RadioFrame System Introduction RFN_3.1 Beta 1 1 Introduction 1.1 Scope of the Manual This manual describes standards for installing, modifying and maintaining RadioFrame Networks’ equipment at RadioFrame customer sites. All specifications and requirements pertain to the RadioFrame Networks equipment required in RFN customer iDEN (integrated Digital Enhanced Network) and 802.11b installations. RadioFrame Networks recommends reading the entire manual before attempting to install or operate RadioFrame Networks equipment. 1.1.1 Prerequisites and Responsibilities All installers are required to be trained and certified to install RadioFrame Networks equipment as follows: • Installers shall be trained for specific equipment or the warranty on that equipment may be invalidated. • All installers shall be able to use required tools and test equipment properly. • Installers shall clean up and properly store tools at the end of each day’s work. The installation Project Manager shall be responsible for, but not limited to: • Ensuring that all detailed engineering specifications, job drawings, technical information, and documentation required to successfully complete an installation are on site. • Making an inventory and conducting a visual inspection of all equipment shipped to the job site prior to the installation. • Identifying any physical damage, defects, or problems that may prevent the proper installation, maintenance, or operation of equipment and reporting this information to the proper parties involved. • Ensuring that all installation job activities are completed in a safe and professional manner whether or not the specific activity is mentioned in this manual. • Ensuring that all locations where painted surfaces have been marred are touched up. The touch-up paint shall be the same quality and shade as the paint used on the item being touched up. • Using this Method of Procedure/RadioFrame System manual to ensure that each specific job has been performed. • Ensuring that the site is cleaned up after installation.

Method of Procedure Introduction 2 RFN_3.1 Beta Preparation of a site and installation of equipment requires close coordination between RFN, RFN’s customer and its customers, and designated third-party RFN Certified Integration Partner(s). Domains of responsibilities are shown in the following table. Task Responsible Party Prepares system design and quotes RFN Customer Provides Project Management, including site survey RFN Customer Constructs site, including racks, ironwork (ceiling support, ladder racks, etc.), AC power, DC power, and battery backup systems. RFN Customer/Customer Lays conduit and cable, installs new fiber raceways, and fire stopping after cables have been laid. RFN Certified Integration Partner Installs, tests, and commissions RadioFrame Networks equipment, including site acceptance. RFN Certified Integration Partner Maintains RadioFrame Networks equipment, including logbook. RFN Customer/Customer 1.1.2 Site Documentation The following documents are required for installing, commissioning, testing, and maintaining RadioFrame Networks equipment. Some or all of this documentation will be left on site. In addition, a logbook will be stored on site that will be used for tracking all changes, updates, and maintenance work done on RadioFrame System equipment.

RadioFrame System Introduction RFN_3.1 Beta 3 1.1.3 Reference Documents The following documents are intended to supplement the information contained in this manual. • RF Planning Guidelines for iDEN Installations, RadioFrame Networks, 990-1001-00 • Customer Release Notes RFN_3.1, RadioFrame Networks, P/N 991-1000-31 • Gen 3 Site Controller System Manual, Motorola, 68P80801E30-O • PECO II Rectifier System Manual: 127NHL-IBWS • PECO II System Manual 40-719010-1005 • Battery Manufacturer’s Installation and Maintenance Documentation • Quality Standards—Fixed Network Equipment (FNE) Installation Manual (R56), Motorola, R56 current edition • National Electrical Code (NEC), current edition 1.2 Quality Standards The installation section of this manual requires the Motorola Quality Standards-Fixed Network Equipment (FNE) Installation Manual (R56) as a reference. The R56 contains onsite installation, integration, optimization, and maintenance information for trunked radio equipment. Technicians and installation personnel must be familiar with procedures and guidelines presented within the R56 manual. 1.3 Static Sensitive Precautions Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It occurs when electronic printed circuit cards are improperly handled and can result in complete or intermittent failures. Extreme care must be taken while handling, shipping, and servicing boards and RadioBlades. To avoid static damage, observe the following precautions: • Prior to handling, shipping, and servicing equipment, always put on a conductive wrist strap connected to a grounding device. This discharges any accumulated static charges. All RFN RadioBlades and Field Replaceable Units (FRUs), including NPCs and APCs, are shipped with a disposable anti-static wrist strap (RFN P/N 110-0610-00). Warning! Use extreme caution when wearing a conductive wrist strap near sources of high voltage. The low impedance provided by the wrist strap also increases the danger of lethal shock should accidental contact with high voltage sources occur.

Method of Procedure Introduction 4 RFN_3.1 Beta • Handle boards by the edges and avoid touching any conductive parts of the board with your hands. • Never remove a board with power applied to the unit (hot-pull) unless you have verified it is safe to do so. Make sure the unit will not be damaged by removing the board. • Avoid carpeted areas, dry environments, and certain types of clothing (silk, nylon, etc.) during service or repair due to the possibility of static buildup. • Apply power to the circuit under test before connecting low impedance test equipment (such as pulse generators, etc.). When testing is complete, disconnect the test equipment before power is removed from the circuit under test. • Be sure to ground all electrically powered test equipment. Connect a ground lead (-) from the test equipment to the board or module before connecting the test probe (+). When testing is complete, remove the test probe first, and then remove the ground lead. • Place all boards and RadioBlades on a conductive surface (such as a sheet of aluminum foil) when removed from the system. The conductive surface must be connected to ground through 100kΩ. • Never use non-conductive material for packaging boards or RadioBlades for shipment or storage. All units should be wrapped with anti-static (conductive) material. Replacement units shipped from the factory are packaged in a conductive material. • If possible, retain all original packing material for future use. 1.4 Safety Precautions Read all the notices in this section prior to installing or using the RadioFrame System or any of its components. 1.4.1 Safety Warnings Warning! Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Warning! This product relies on the building’s installation for short-circuit (over current) protection. Ensure that a fuse or circuit breaker no larger than 120VAC, 15A U.S. (240VAC, 10A international) is used on the phase conductors (all current-carrying conductors).

RadioFrame System Introduction RFN_3.1 Beta 5 Warning! To comply with FCC RF exposure requirements, iDEN antennas must be installed to provide at least 8 inches (20 cm) separation from all persons, with antenna gain not exceeding zero (0) dBi. Warning! Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available. Warning! The plug-socket combination must be accessible at all times because it serves as the main disconnecting device. Warning! The RadioFrame Unit (RFU) is intended to be mounted on a wall. The RFU can also be installed on or above a ceiling. Please read the RFU mounting instructions carefully before beginning the installation. Failure to use the correct hardware or to follow the correct procedures could result in a hazardous situation to people and damage to the system. Warning! Ultimate disposal of this product should be handled according to all national laws and regulations. 1.4.2 Safety with Electricity Warning! To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and WAN ports both use RJ45 connectors; incorrect interconnection can cause equipment damage. Use caution when connecting cables. Warning! Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals. Warning! Hazardous network voltages are present in WAN ports regardless of whether power to the attached equipment is OFF or ON. To avoid electric shock, use caution when working near WAN ports. When detaching cables, detach the end away from the router first. Warning! Do not touch the power supply when the power cord is connected. For systems with a power switch, line voltages are present within the power supply even when the power switch is off and the power cord is connected. For systems without a power switch, line voltages are present within the power supply when the power cord is connected.

Method of Procedure Introduction 6 RFN_3.1 Beta 1.4.3 Recommendations 1.4.3.1 Safety Recommendations • Keep tools away from walk areas where you and others could fall over them. • Wear safety glasses if you are working under any conditions that might be hazardous to your eyes. • Do not perform any action that creates a potential hazard to people or makes the equipment unsafe. 1.4.3.2 Guidelines for Working on Equipment Powered by Electricity • Locate the emergency power off switch for the room in which you are working. Then, if an electrical accident occurs, you can act quickly to turn off the power. • Before installing, removing, or repairing an NCU, ACU or URU, unplug the power cord. • Disconnect all power before working near power supplies. • Do not work alone if potentially hazardous conditions exist. • Never assume that power is disconnected from a circuit.

Otherwise, assess the condition of the victim and then call for help. • Determine if the victim needs rescue breathing or external cardiac compressions, then take appropriate action.

RadioFrame System System Description RFN_3.1 Beta 7 2 System Description The RadioFrame Networks iDEN/802.11b solution generates RF within the building using low-power transceivers that are placed as needed to meet coverage and capacity requirements. The low-power nature of the transceivers minimizes interference with the surrounding macrocell system so that the macrocell system views the RFN iDEN/802.11b solution as a peer. The RFN iDEN/802.11b solution is remotely monitored down to the component level, including alarms and system performance, using a web-based interface. The RadioFrame Networks iDEN/802.11 solution consists of the following four systems: • iDEN Interface • RadioFrame System • Power Plant • Local Area Network 2.1 Functional Relationships The following diagram depicts the components of each system in the RadioFrame Networks iDEN/802.11 solution. Figure 1 The RadioFrame Networks iDEN/802.11b solution consists of the iDEN Interface, the RadioFrame System, a Power Plant, and the customer’s Local Area Network.

Method of Procedure System Description 8 RFN_3.1 Beta 2.1.1 The iDEN Interface The iDEN (integrated Digital Enhanced Network) interface supplies T1 and GPS antenna connections, via the iSC-3, for the RadioFrame System. The iDEN interface also provides an Environmental Alarm System (EAS) and a Channel Service Unit (CSU) for the T1 input to the iSC-3. 2.1.1.1 integrated Site Controller (iSC-3) The integrated Site Controller, or iSC-3, consists of a site controller and an Environmental Alarm System (EAS). Most systems are configured with two iSC-3s (an active and a standby) and one EAS. For more information about the iSC-3, refer to the Motorola document Gen 3 Site Controller System Manual, 68P80801E30-O. Figure 2 The iSC-3 functional diagram.

RadioFrame System System Description RFN_3.1 Beta 9 Site Controller CPU Board The following is a list of CPU Board main features: • PPC750 host processor with 1MByte L2 cache • MPC8260 communications processor for all serial I/O • 32 MBytes of FLASH on the PPC bus • 64 MBytes of SDRAM on the PPC bus • 16 MBytes SDRAM on the MPC8260 local bus • 32 KBytes battery backed SRAM with real time clock on the MPC8260 local bus • Four E1/T1 span lines supported by a single quad E1/T1 framer/line driver IC • One 10/100BaseT Ethernet port • Three 10Base2 Ethernet ports • One X.21 port • One IEEE 1284 parallel port • Two RS232 serial ports • Internal or remote GPS Receiver • Three time/frequency reference outputs Environmental Alarm System (EAS) The EAS provides a central location for site alarm signal processing. The EAS monitors site environmental conditions, including AC power, smoke alarms, intrusion alarms, antenna tower lights, etc. The Site Controller and EAS interact in a master/slave relationship. The Site Controller sends commands to the EAS to determine the status of alarm inputs or set the state of control outputs. The EAS, in turn, sends alarm status responses to the Site Controller. The EAS continuously scans the status of the alarm inputs, ensuring that all alarms are consistently monitored. Alarm wiring routes directly from the RadioFrame Networks site equipment and power supply equipment to the EAS. The EAS sends alarm status to the site controller via the IEEE 1284 parallel connection. The EAS can monitor up to 48 inputs, each of which must be a contact closure between the alarm input and its return. Alarm inputs are optically isolated. The EAS also provides eight relay outputs. Four RJ45 connectors replicate the physical interfaces to the three RF cabinets and one control cabinet. The remaining alarm inputs and relay outputs are accessible via two 50-pin DSUB

Method of Procedure System Description 10 RFN_3.1 Beta connectors. These connectors are cabled to punch blocks to allow simple installation of the remaining site alarm and control I/O. Figure 3 Environmental Alarm System functional diagram. 2.1.1.2 GPS Antennas The Global Positioning System (GPS) antenna provides the timing reference to the iSC-3. One GPS antenna with a dedicated 50ohm coax is required for each iSC-3. Generally, the GPS antennas are to be mounted on a stable platform with a clear view of the southern horizon and secured access. Horizontal separation of the antennas is not required for proper operation; however, it is generally required to increase survivability of the antenna from falling objects. GPS satellite acquisition and lock can be verified with a handheld GPS receiver prior to installation. Four satellites should be available.

RadioFrame System System Description RFN_3.1 Beta 11 Coax size, 1/2" or 7/8", is determined by the overall length of the coax run (the distance in feet from the GPS antenna to the top of the equipment rack containing the iSC-3). The maximum run length for using 50ohm 1/2" coax is 166'. The maximum run length for using 50ohm 7/8" coax is 290'. 2.1.1.3 Channel Service Unit (CSU) The Channel Service Unit (CSU) provides the T1 connection between the iSC-3 and the telephone company that provides the T1 line. The CSU provides surge protection to the T1 line and loop-back testing for the telephone company. 2.1.2 RadioFrame System (RFS) The RadioFrame System is comprised of several components, which are connected in a ‘tree’-style architecture (see the following illustration): • The Network Chassis Unit (NCU) acts as the sole connection point (i.e. the ‘root’) to all ACUs (and RFUs) which ‘branch’ off this ‘root’ chassis. The NCU also connects to the iSC and the customer LAN. • Up to eight Airlink Chassis Units (ACUs) connect from the NCU and send traffic, power and timing to the RFUs over standard CAT 5 wiring. • Up to 64 RadioFrame Units (RFUs), that house the RadioBlades, provide access points mounted on walls and ceilings. • Up to seven iDEN RadioBlades (RBs) can be installed per RFU, and up to three 802.11b RadioFrame Access Points (RAPs) per RFU; the combined total is seven RBs/RAPs per RFU. Each iDEN RB and RAP provides a single RF transceiver that supports iDEN or 802.11b (WLAN). • Up to two Universal Repeater Units (URUs) can be installed to extend the distance between components from 328’ (100 meters) to 984’ (300 meters). • An Ethernet Media Converter is provided to connect the NCU and the iSC-3.

Method of Procedure System Description 12 RFN_3.1 Beta Figure 4 The RadioFrame System uses a ‘tree’-style architecture to connect components. 2.1.2.1 Network Chassis Unit (NCU) The Network Chassis Unit is the main controller of the RFS, providing external network interfaces and the baseband network processing for the ACUs and RFUs. The NCU also is the interface between the RFS and the telecommunications switching entities.

RadioFrame System System Description RFN_3.1 Beta 13 Figure 5 NCU functional diagram. 2.1.2.2 Airlink Chassis Unit (ACU) The Airlink Chassis Unit provides the baseband airlink processing for up to 8 RadioFrame Units, providing a coverage area up to 250,000 square feet. The ACU is the interface between the RFUs and the Network Chassis Unit, and provides power, signals, and timing to the RFUs. Figure 6 ACU functional diagram.

Method of Procedure System Description 14 RFN_3.1 Beta 2.1.2.3 RadioFrame Unit (RFU) The RadioFrame Unit serves as the access interface between signals received from mobile terminals and the airlink processing performed in the ACU. The RFU connects to the ACU via a single CAT 5 connection, and receives its power, signals, and timing from the ACU. Each RFU holds up to 7 RadioBlades in combination of: a maximum of 6 iDEN RadioBlades, a maximum of 3 RAPs. Figure 7 RFU functional diagram. 2.1.2.4 iDEN RadioBlade (RadioBlade or RB) Each iDEN RadioBlade provides a single RF channel transceiver supporting the iDEN voice standard. Each RadioBlade contains an onboard omnidirectional antenna and provides a coverage area of approximately 32,000 square feet (nominal 100’ radius cell). Each RadioBlade inserts into a slot in the RFU. Figure 8 iDEN RadioBlade functional diagram.

Each RAP contains an onboard omnidirectional antenna and provides a coverage area of approximately 32,000 square feet (nominal 100’ radius cell). Each RAP inserts into a slot in the RFU. Figure 9 RadioFrame Access Point (RAP) functional diagram. 2.1.2.6 Universal Repeater Unit (URU) The Universal Repeater Unit (URU) extends the distance between RFS components, including the NCU and the iSC, from 328’ (100 meters) to 656’ (200 meters). Up to two URUs can extend the distance to 984’ (300 meters). The unit repeats the Ethernet signal and timing, and can also supply power to an RFU. 2.1.2.7 Ethernet Media Converter The Ethernet Media Converter (Allied Telesyn model number AT-MC15) is installed between the NCU and iSC-3. The MC15 converts signals from twisted pair cable to thinnet cable, and vice versa, providing seamless connection between two different media with a 10Base-2 BNC connector. An external 12 Vdc power adapter supplies power to the media converter. 2.1.3 Power Plant The Power Plant consists of two components: a rectifier and battery plant.

The customer’s LAN may include a variety of equipment, including switches, routers, and gateways. The RFS connects to the LAN via Port 2 on the front of the NCU. The RAPs installed in the RFUs support the LAN. Figure 10 RFS and customer LAN functional diagram. In the above diagram, an optional “gateway” device is shown between the customer LAN and the RFS to provide a point of control, thus isolating the RFS from the customer’s LAN. The gateway may be used to perform inter-network routing and access control, permitting only authorized users access to the customer LAN via the RFS. It may also perform service accounting and user mobility functions. NOTE: Though not required, the use of a gateway device is strongly recommended, particularly for use as an access control mechanism to prevent Customer LANNCUACURFUsACURFUsGateway

Method of Procedure System Description 18 RFN_3.1 Beta unauthorized access to the customer LAN. In addition, while a router between the RFS and the customer LAN is not required, it is highly recommended that a combination router and security gateway be used. The RFN implementation of 802.11b provides a transparent MAC layer bridging function between the RFS and the customer’s LAN. No layer 3 (IP) protocol routing is required for operation. The NCU contains a card that is assigned a fixed address during installation. Once the NCU has been configured, the NCU will automatically assign IP addresses to each network element in the RFS. 2.2 Physical Relationships The RadioFrame System is laid out as follows: • Main rack: Located in a Telco closet, the main rack houses the entire iDEN Interface and Power Plant, along with the NCU and one ACU of the RadioFrame System. • Remote ACUs: Up to seven additional ACUs can be connected to the NCU. The remote ACUs are installed in closets or Telco rooms throughout the building to support additional RFUs. • RFUs: Up to 8 RFUs per ACU are installed on walls or on or above ceilings throughout the building to provide coverage for the iDEN/802.11b RFS; RFUs house the iDEN RadioBlades RAPs. • LAN: Customer equipment located in a customer-defined area. The following illustration depicts a typical RadioFrame Networks iDEN/802.11 solution. The main rack is located on Floor 4 housing the iDEN Interface, Power Plant, and the NCU and one ACU of the RFS. The Customer LAN equipment is also located on Floor 4. Remote ACUs are located on Floors 1 and 2, with each ACU supporting up to eight RFUs. The ACU located on Floor 1 also supports RFUs in the parking level. RFUs on each floor of the building, 1, 2, 3, 4 and the parking level, support one of three sectors. RFUs on Floors 1 and 4 support sector 1. RFUs in the parking level and on floor 3 support sector 2. RFUs on Floor 2 support sector 3.

RadioFrame System System Description RFN_3.1 Beta 21 2.2.2 Remote ACUs Remote ACUs are located in Telco rooms or other closets throughout the building mounted in 19” EIA-standard compliant racks or equivalent. The racks for remote ACUs may be either floor or wall-mounted racks. Any other method used to mount the remote ACU is not approved, and could void the warranty on the product and other components in the RFS. 2.2.3 RFUs RFUs are located throughout the building to provide coverage for specific areas. RFUs are typically mounted on or above the ceiling, or on a wall. The following illustration depicts typical RFU locations using a simple floor plan. Three RFUs, denoted by triangles, are located along the central hallway providing coverage to each portion of the floor. Antenna coverage for each RFU is a 100-foot radius (30.3 meters) or approximately 32,000 square feet (2,920 square meters). Figure 13 RFUs are located throughout the building to provide coverage. 2.2.3.1 RadioBlades and RAPS The number and combination of RadioBlades and RAPs to be installed in each RFU is driven by the coverage and capacity requirements of that particular portion of the building. A maximum of six iDEN RadioBlades can be installed in each RFU. A maximum of three RAPs can be installed in each RFU. The combined total of iDEN RBs and RAPs is seven per RFU. Each RadioBlade is supplied with an antenna that must be installed vertically and pointed down towards the ground.

An Ethernet cable connection must available from the LAN to the main rack for connection to the NCU.

RadioFrame System Pre-Installation RFN_3.1 Beta 23 3 Pre-Installation This section provides pre-installation information for a RadioFrame System at a RFN customer site. A pre-installation site review and evaluation helps prevent potential equipment installation problems. Consider every subject discussed in this section before installing the iDEN/802.11b RFS. 3.1 Receipt of Equipment The main rack is provided pre-installed with the following equipment: • Rectifier, PECO II • NCU (Network Chassis Unit), RadioFrame Networks • ACU (Airlink Chassis Unit), RadioFrame Networks • CSU (Channel Service Unit), DTS • EAS (Environmental Alarm System), Motorola • two iSC-3s (integrated Site Controllers), Motorola • two battery trays, 2 x 100 amp batteries All other equipment is RadioFrame Networks equipment and is shipped as follows: each RFU, remote ACU, and URU is shipped in its own box. The iDEN RadioBlades and RAPs are shipped several to a box and individually wrapped in antistatic packaging. Unpack each unit only at the time of installation—leave items in their shipping containers until ready for use. Unpacking instructions are contained inside each shipping container. 3.1.1 Equipment Inspection Inspect the RadioFrame Networks iDEN solution equipment immediately upon receipt. If obvious damage has occurred to shipping containers before unpacking, contact the shipping agent. Ask that a representative of the shipping company be present while the equipment is unpacked. Observe guidelines for safe handling of electrostatic sensitive devices or equipment to prevent damage due to electrostatic discharge. A conductive wrist strap is provided with each RFU and should always be worn when handling any electrical component, including iDEN RadioBlades. Check for the following: • loose or damaged equipment in the pre-installed main rack • dents, scratches, or other damage on all sides of each component • physical damage to iDEN RadioBlade or RAP antennas or connectors

RadioFrame System Pre-Installation RFN_3.1 Beta 25 3.2 Site Planning Licensing and the availability of space help to determine a site selection. On a RFN customer owned or controlled site, field engineering and program management will plan the system and site layouts. Planning helps prevent potential on-site and off-site interference from other RF systems. Site layouts should always be planned to minimize inter-cabling lengths between RF equipment. 3.2.1 Site Considerations 3.2.1.1 Main Rack The site for the main rack should not contain windows and must be able to resist extreme weather conditions. It should be designed to meet the requirements of the American National Standards, Building Code Requirements for Minimum Design Loads in Buildings and Other Structures. RFN recommends the following considerations when selecting a site: • A minimum floor space of at least 42 square feet is recommended to allow enough space for front and rear access to the main rack. • The minimum ceiling height of at least 8’6” above a finished floor is required to allow enough space for the height of the main rack and cable access at the top of the cabinet. • The ceiling structure should be able to support a cable tray assembly for routing the inter-cabinet cabling and other site cabling. The cable tray assembly is mounted to the site ceiling and walls per site plan and should be at least 7’6” from the site floor to allow for the height of the main rack. • The minimum door dimensions should be at least 3’ wide and 6’8” high. • All exterior doors should have tamper proof locks installed for security purposes. • The interior site environment should be maintained at a constant 78° F (25.6° C). The site should be capable of maintaining this temperature in an outside ambient temperature range of -10 to +105° F (-23.4 to +40.6° C). RadioFrame Networks iDEN solution equipment is not approved or recommended for outdoor use. • Proper surge protection is required for all antennas and power inputs to prevent potential damage to site equipment. • The site floor should be level to within 1/8” and able to support the weight of site equipment.

Method of Procedure Pre-Installation 26 RFN_3.1 Beta 3.2.1.2 Remote ACUs Remote ACUs are located in Telco rooms or other closets throughout the building. Any such location must be free of dust, wind, salt and liquids. All other operating environment specifications that apply to an ACU in the main rack also apply to a remote ACU. Remote ACUs must be mounted in a 19” EIA-standard compliant rack or equivalent. The racks for remote ACUs must be either floor or wall mounted. Any other mounting method is not approved, and could void the warranty on the product and other components in the RFS. The number and location of remote ACUs is determined by the number of RFUs required to provide coverage for the iDEN/802.11b RFS. 3.2.1.3 RFUs The RadioFrame System is designed to simplify site planning. The RFS intentionally limits antenna coverage to a 100-foot radius (30.3 meters) or approximately 32,000 square feet (2,920 square meters). To determine the number of RFUs required to provide coverage, divide the desired area’s square footage by the RFS minimum coverage area (32,000). This determines the minimum number of RFUs. The capacity requirements of the site determine the number of iDEN RadioBlades and 802.11b RAPs that will be required. RFUs are mounted so that the antennas of the installed iDEN RadioBlades and 802.11b RAPs point to the ground. This orientation of the antennas must not be changed. The number and exact location of RFUs is determined by capacity and coverage requirements, as well as site considerations, such as mounting considerations, interior structures, and interference from macro systems. For more information on site planning considerations, refer to the RFN document, RF Planning Guide for RadioFrame iDEN Systems (P/N 990-1001-00). 3.2.1.4 LAN Connecting the RFS to the customer LAN requires only a single Ethernet cable from the NCU in the main rack to the customer’s LAN equipment (gateway, switch, router etc.). No other site considerations are required. 3.3 Main Rack and Supporting Hardware Most communications equipment is mounted into standard 19” EIA racks or enclosed cabinets. Follow the rack and/or equipment manufacturer's instructions when installing equipment into racks or cabinets. For example: • All supplied bracing hardware shall be properly utilized.

RadioFrame System Pre-Installation RFN_3.1 Beta 27 • Proper hardware shall be used to secure equipment. • Convected heat transfer from one piece of equipment rack to another shall be considered. Heat baffles may be required. 3.3.1 Mounting The front panels of the NCU, ACU, iSC-3s, CSU, PDU and EAS are 19” wide to allow for installation into 19” wide cabinets. All of this equipment is typically installed into a 19” wide cabinet prior to shipment to the site. For rack installation instructions for the NCU and ACU, see Appendix C NCU and ACU Main Rack Installation. 3.3.1.1 Plumb and Squareness Equipment shall be level and plumb. Equipment level shall be tested on a known flat surface in at least two directions to verify accuracy. Equipment shall be parallel or perpendicular to the surrounding walls and adjacent installed equipment. 3.3.1.2 Anchoring Anchoring is the mechanical fastening of the communications equipment to suitable locations using hardware acceptable for the application. Although every installation is unique, certain methods for anchoring shall be adhered to for all installations. Typically, at least four anchor points shall be used on each item of equipment mounted to the floor. The only exception is when the equipment manufacturer supplies other than four mounting points. 3.3.1.3 Mounting on Concrete Floors Equipment racks or cabinets should be positioned and anchored to the floor using preferred mounting methods. In general, observe the following: • An anchor specifically designed for concrete shall be used. The preferred method for anchoring racks, or other ancillary equipment to concrete floors is to use flush-mount expansion anchors properly sized for the application. Flush mount expansion anchors do not extend above the surface of the floor and provide an easy bolt down. They also provide the required pullout and shear strength. If at a later time equipment needs to be moved, flush mount expansion anchors do not get in the way. NOTE: Unless an isolating mounting scheme is used (refer to section 3.3.1.4 Isolated Mounting, next in this section), ensure that no anchors come in contact with reinforcing rods or wire mesh buried in the concrete; the rack shall be electrically isolated from any other equipment or materials at the site.

Method of Procedure Pre-Installation 28 RFN_3.1 Beta • In applications where flush-mount expansion anchors are not preferred or acceptable, then wedge-type stud anchors may be used. • All concrete anchors shall be zinc-plated carbon steel for standard applications, galvanized steel for mildly humid or corrosive environments, and yellow zinc or stainless steel for humid, highly corrosive, or acidic environments. Minimum bolt diameter shall be 10 mm (0.375 in.) with 12 mm (0.5 in.) preferred. Anchor embedment depth should be at least 76 mm (3 in.) to provide good tensile and shear strength. Follow manufacturer's instructions for depth reduction when rebar is encountered. A heavy-duty washer should be part of the anchor assembly to ensure the equipment is secure. 3.3.1.4 Isolated Mounting Isolated mounting is recommended to prevent a second electrical path to ground through the concrete floor, and is required for the installation of certain equipment. In these cases expansion anchors are inserted into the concrete floor. However, isolation of the equipment rack is ensured using an insulating plate and hardware. If the installation is in an earthquake zone, additional anchors are used. NOTE: Motorola equipment frames are always required to use, and are shipped with, isolating washer and bolt assemblies, and have separate insulating mounting plates. Refer to the Motorola document 68P09226A18 Frame Mounting Guide for more information. 3.3.1.5 Mounting on Wood or Fiberglass Floors Appropriately sized lag bolts shall be used for mounting on wood or fiberglass floors. If the underside is accessible and the floor stability is questionable, then thru-bolting may be desirable. RFN recommends mounting non-racked ancillary equipment on a "C-channel" type of mounting track where possible. This provides for easy cleaning and some isolation in the case of standing water. Another benefit of installing non-rack mounted equipment off the floor is that the weight is distributed across the floor. In these cases, C-channel type mounting provides multiple floor anchor points where the equipment provides only four to six anchor points. When mounting racks to raised computer floors, 0.5 in. (13 mm) minimum diameter allthread rod and flush-mount expansion anchors shall be used to anchor to the concrete subfloor. When mounting consoles to a raised floor, 0.375 in. (10 mm) minimum allthread rod and hardware shall be used for anchoring. Mounting arrangement shall be in accordance with mounting kit manufacturer's instructions.

RadioFrame System Pre-Installation RFN_3.1 Beta 29 3.3.1.6 Anchoring Equipment to Raised Floors The anchoring of overhead and wall-mounted devices present a number of considerations. Placement is very important; if equipment is bolted to a wall that is on an aisle, the aisle may be unacceptably narrowed with the danger of injury to personnel. Also, the serviceability of the equipment being mounted to adjacent equipment may be inhibited. Overhead applications generally include coax cabling, cable runways, and mounts for earthquake bracing. All overhead applications should keep in mind loading of overhead surfaces. Care must be exercised when deciding how much can be held by the ceiling without some sort of building foundation support. In the case of earthquake bracing equipment, cable runways can be secured overhead then affixed to the equipment racks providing acceptable foundation support. When anchoring cable runways to ceilings or walls, the manufacturer-supplied support hardware shall be used. Anchors used in overhead applications vary depending on the ceiling structure as follows: • For concrete and wood ceilings, the same principles discussed in floor anchoring apply. • For an exposed steel l-Beam ceiling, many cable runway manufacturers make beam clamps for C-channel or threaded drop rods. • For corrugated steel ceilings, C-channel tracks can be affixed to the ceiling using properly sized lag bolts. The C-channel will span the corrugated steel and provide multiple anchor points. For drywall or plasterboard ceilings, special considerations are required: • If the drywall is on steel or wooden roof joists, locate and tap into the roof joist with lag bolts. • C-channel mounting can be used. • An alternative to C-channel mounting is using large toggle or molly wings with hex head tap bolts. NOTE: Make certain joists are properly located before drilling into drywall. 3.3.1.7 Seismic Anchoring Seismic anchors are designed, tested, and specified for seismic zones 3 and 4. Seismic anchors enhance the stability of equipment due to the special characteristics specifically suited to the dynamic and cyclic loading effects experienced during earthquake events. As such, anchors shall be used that are manufactured to particular specifications that make them the most resistant to the effects of dynamic and cyclic loading effects.

Method of Procedure Pre-Installation 30 RFN_3.1 Beta Selected anchors shall meet standards set forth in NESS (Network Equipment Building Systems) TR-64 and ASTM (American Society For Testing and Materials) 488-90 for earthquake compliance. This testing evaluates anchors for bolt failure from shearing and from pullout or slippage. Compliance with these standards requires that the anchor not allow a standard top heavy 7 ft. (2.2 m) rack to have a deflection greater than 3 in. (7.6 cm) at the top of the frame. This compliance will also adhere to Bellcore Technical Specifications AU-434 for earthquake concrete expansion anchors. Anchor selection criteria shall comply with all general requirements for standard concrete anchors plus meet the above seismic requirements. All seismic anchoring shall be enhanced with top cabinet or rack bracing. Seismic Considerations All RadioFrame Networks equipment is seismically rated to withstand vibrations of a Level 3 earthquake. The property owner is responsible for any damage to RFN equipment due to building or rack structures that are not rated to withstand vibrations of a Level 3 earthquake, or not secured to withstand vibrations of a Zone 4 earthquake. Site protection from earthquakes may be required in certain areas. Typically, this would be an area having historical data indicating a Moment Magnitude rating of 3 or 4. Note that areas other than historically prone areas may need consideration. Obviously, addressing such concerns results in increased costs of equipment installation. A certified architect specializing in earthquake-resistant installation shall be consulted for seismic designs and recommendations in areas where the potential loss of the site may outweigh associated costs of earthquake-resistant design. In the United States, it is recommended to consult the US Geological Survey for more information regarding earthquake probability and historical data for various areas. In other areas, similar consultation should be done. • The US Geological Survey information can be accessed at: http://geohazards.cr.usgs.gov • Seismic maps are available at: http: //www.neic.cr.usgs.gov Earthquake-resistant design should be contracted to a firm specializing in such work. However, the following general considerations need to be observed and factored into a seismic design program: • Equipment shall not be secured to both the shelter walls and floors, since dissimilar movement between these surfaces is likely in an earthquake. • Mounting should provide for some "sway" in the overall equipment mounting, thereby absorbing the energy of an earthquake. This is typically accomplished by rigid mounting of racked equipment or cabinets at the base, while semi-rigidly attaching the rack top using 1/8 in (3.2 cm) diameter steel

RadioFrame System Pre-Installation RFN_3.1 Beta 31 braided wire rope. Wire rope anchors are then secured to ceilings joists. The benefit of this type of installation is that racks are allowed to sway within limits but can't fall over. • Cabinet designs with wide footprints can be used to help prevent cabinets from tipping over. • Columns of cabinets stacked and bolted back-to-back present a very stable and wide footprint. The bottom cabinets shall still, however, be bolted to the floor for complete security. • Some cabinets can be outfitted with outrigger-type support legs to prevent tip-over. These outriggers alone do not provide adequate earthquake protection, but are typically adequate if the cabinet is bolted to the floor. NOTE: If a rack is seismic rated, any add-on aftermarket equipment or equipment that is not seismic rated will render the overall package as not being seismic tested and certified as a unit. Therefore, the unit would no longer be considered as seismic rated. • When bolting down to computer floor, be sure to anchor all the way to the subfloor. • Columns of cabinets must be supported, though not rigidly. Rigid mounting will result in extreme vibration and resultant mechanical failure during an earthquake. Semi-rigid mounting is preferred. Semi-rigid bracing is defined as bracing which allows a measurable amount of movement. • Some computer floors lose mechanical integrity if several panels are simultaneously removed. This could lead to equipment floor collapse during at earthquake. The flooring manufacturer shall be consulted for floor removal procedures. • Equipment shall be stabilized by a top support. This is critical in preventing a column of equipment from toppling, causing injury to personnel. The footings cabinet columns and racks shall be bolted to the floor as appropriate, using concrete anchors. Sometimes the cabinet columns are placed on C-channel tract or wooden pedestals. • Cables and transmission lines should not be installed rigidly, and without strain relief. Make broad service loops. • Lighting fixtures should be prevented from swaying by the addition of one or more guy wires. A fluorescent lighting fixture in particular, can be very dangerous if allowed to swing against a wall or equipment racks, shattering and spraying broken glass below. Fluorescent lighting fixtures shall have protective lenses or protective plastic sleeves that cover the fluorescent tube, preventing broken glass from falling on occupants. • Storage cabinets shall be secured to the wall to prevent upset. Storage cabinets shall also have closable, secured doors to prevent contents from spilling during an earthquake.

Method of Procedure Pre-Installation 32 RFN_3.1 Beta • Ladders and other large objects shall be secured to a wall or removed from the equipment room when not in use. These items have been known to fall into “live” equipment during earthquakes. 3.3.2 Clearances Proper spacing of equipment is essential for efficient use of the room area, ease of maintenance, and safety of personnel. The following specifications have been established to meet the National Fire Protection Associations (NFPA) Code, and the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) standards. Any local regulations, as applicable, shall also be adhered to. • To provide adequate working space, a 576 sq. in. (0.37 m2) footprint (as measured from facing equipment surfaces) shall be used for combining equipment. NOTE: Local codes may require additional clearance. In such cases, the local code shall prevail. • 36 in. (91 cm) front and side aisles shall be maintained around electrical panel boards (NPPA 70, Article 110-26). • 36 to 48 in. (91 to 123 cm) front, side, and (where applicable) rear aisles are required for servicing equipment. • 36 in. (91 cm) aisle shall be maintained in front of all equipment. • 36 in. (91 cm) aisle shall be maintained between at least one end of an equipment row and building wall or other obstruction; longer aisles may require additional access breaks. Larger aisles and additional access breaks in a row may be require as the row becomes longer, such that a fire in the aisle does not prevent egress. Comply with any codes regarding fire egress specifications. • Ingress and egress to equipment rooms shall conform to NFPA 70, Article 111 and local building and fire codes. • In US installations where a facility is to be normally occupied, American with Disabilities Act (ADA) shall be complied with. Some general requirements of ADA are 91.5 cm (36 in.) wide doors, ramps and safety rails, 36 in. (91.5 cm) can turn around clearance for wheelchairs, and specific placement of telephones, fire extinguishers, light switches, etc. NOTE: ADA compliance in architectural plans may be required in obtaining a construction permit in some localities.

This demarcation (demarc) point connects to the T1/E1 through a surge arrestor. The following illustration shows the T1/E1 interface with the iDEN/802.11b RFS. Figure 15 Telco (T1/E1) interface with the iDEN/802.11b RFS. The surge arrestor must be adequately grounded as outlined in the Quality Standards Fixed Network Equipment - Installation Manual (R56). The surge arrestor usually mounts near the demarcation (demarc) point. The cable connecting the surge arrestor to the Telco SmartJack should be locally procured, or should be provided with the surge arrestor. The cable connecting the iSC-3 to the surge arrestor is locally procured. The following table lists RFN-approved surge suppression equipment.

Cabling within racks and cabinets shall conform to the requirements of NFPA 70, Article 300, Article 800, Article 810, and Article 820. (Refer to ANSI/TIA/EIA-568(a) and 569(a) for additional information.) All cables shall be installed and routed so that personal safety and equipment functionality is not compromised and that all equipment is accessible for servicing. The following requirements apply to cabling installed in racks or cabinets. 3.3.10.1 Securing cabling within racks or cabinets To help prevent damage or accidental disconnection, cables and conductors shall be secured at intervals of no more than 3 ft (91 cm). Attachment shall be accomplished in a manner that does not restrict access to the equipment in the rack or cabinet. Insulated standoffs are recommended for use in racks or cabinets. The standoffs should be of sufficient length to maintain the proper cable separation. Nonmetallic cable ties shall be used to secure cables and conductors. Attachment shall be tight enough to secure cables without crushing them. Cables that span a gap greater than 2 ft (61 cm) shall be supported. 3.3.10.2 Routing cables within racks and cabinets Grounding conductors within racks or cabinets shall be routed toward the RGB, MGB, SSGB, or ground bus conductor. Connections to the RGB or ground bus conductor shall always be made with the equipment grounding or tap conductors being routed toward the MGB, SSGB, or RGB. At points where grounding conductors must pass through a hole in a metallic surface and the hole is slightly larger than the conductor, the conductor shall be bonded to the metallic surface through which it passes. If the hole or opening is much larger than the conductor, and it is intended to accommodate several conductors, the conductor is not required to be bonded. Cables in racks or cabinets shall be sized to length, and shall be installed and routed neatly and in a professional manner. Excess cable shall not be coiled on top of cabinets or racks.

Method of Procedure Pre-Installation 40 RFN_3.1 Beta AC power cords longer than necessary may be looped down and back up a rack or cabinet. Excess lengths of AC power cord shall not be coiled on top of racks or cabinets. 3.3.10.3 Protecting cables within racks and cabinets Grounding conductor tap joints shall be installed in order to prevent the conductor or connection device from coming in contact with metallic surfaces. Where cables or conductors are routed through holes in metallic surfaces or near sharp edges, the sharp surfaces shall be suitably protected with a grommet or similar material to help protect the cable or conductor from damage caused by sharp edges. 3.3.10.4 Cable bending radius within racks and cabinets Grounding conductors of all sizes shall maintain a minimum bending radius of 8 in. (20 cm). The angle of any bend shall be not less than 90°. The bending radius of CAT 5 cables shall be not less than 10 times the outside diameter of the cable. Follow the cable manufacturer's recommendation and refer to ANSI/TIA/EIA-568 and CSA-T529 for additional information. All other cables shall not have sharp bends that will damage or degrade the performance of the cable. The cable manufacturer's specifications shall be followed. 3.3.10.5 Cable separation and grouping within racks or cabinets Cabling in racks or cabinets shall be grouped according to function. Cable groups within racks and cabinets shall be separated by a minimum of 2 in. (5.1 cm) from other cable groups. Refer to ANSI/TIA/EIA-568a and -569; and NFPA 70, Articles 800-52, 810-18, and 820-52 for more information. 3.3.11 Alarm Blocks All alarm wires shall be tagged and labeled with the appropriate alarm item. All contacts will be normally closed, dry, and isolated from ground. Alarm wire will be neatly run and secured using nylon cable ties/clamps every three feet to walls and existing cable tray. All alarm wiring shall be two-wire, 22 AWG. 3.4 Remote ACUs Up to seven remote ACUs may be installed for a total of 8 ACUs per NCU.

RadioFrame System Pre-Installation RFN_3.1 Beta 41 3.4.1 Mounting Remote ACUs are located in telco rooms or other closets throughout the building, mounted in 19” EIA-standard compliant racks or equivalent. Any other method used to mount the remote ACU is not approved, and could void the warranty on the product and other components in the RFS. NOTE: The ACU may be placed on a flat surface only if the front and back of the unit are accessible and if the side vents are not blocked. In this case, the ACU is not secured and, therefore, is not rated to withstand any level of earthquake, and the warranty may be voided. Currently, the remote ACU does not include a Universal Power Supply (future enhancement). Grounding of the remote ACU is not required by RadioFrame Networks and is the responsibility of the RFN customer or its customer. A bonding ground point for protective earth grounding is provided; #6 screw with internal sems washer. 3.4.2 Clearances • Dimensions: 19" wide x 7" high x 13" deep (approx.) 3.4.2.1 Back • 7” 3.4.2.2 Front • 12” 3.4.2.3 Sides • Left side (facing unit): 0”; right side: 2” 3.4.2.4 Above • Above: 0” 3.4.3 Weight • 27 lbs (fully loaded) 3.4.4 Power • 100-240 Volts AC, 47-63 Hz, 8-3.5A , or • Negative 48-56 Volts DC, 11A

The number of RFUs is determined by dividing an area’s square footage by the minimum RFU coverage area, (32,000’). Typically, a floor plan of each story in the building is used as an aid to identify RFU placement.

RadioFrame System Pre-Installation RFN_3.1 Beta 43 In addition, RFU placement requires taking into consideration such factors as interior structures, multiple-floor installations, elevators and stairwells, and neighboring macro cell systems. For more information, refer to the RFN document, RF Planning Guide for RadioFrame Systems (990-1001-00). 3.5.2 Mounting Once the approximate RFU locations have been identified, determine the mounting configuration required for each RFU—on or above the ceiling, or on a wall. Wall mounts are ideal, provided the wall is of low density. Mounting the RFU to a structural brick or concrete wall can alter the unit’s omni directional pattern. Also, each RadioBlade installed in an RFU is supplied with an antenna designed to be installed vertically and pointed down. Do not change this orientation. Suspended ceilings are very common in commercial buildings and mounting the RFU above the ceiling can work well, provided lower half of the RFU is kept clear of metal objects such as water pipes, wire bundles and light fixtures. The added benefit of an above-ceiling installation is that the RFU is hidden yet still easily accessed. Generally, suspended ceiling panels are of low-density lightweight materials that do not attenuate RF. The metal grid supports typically are spaced at greater than 2-foot intervals and will not dramatically affect the RFUs’ performance if they are kept at least 1-foot away from the antennas. 3.5.3 Clearances • Dimensions: 13.5" wide x 8" high x 5" deep (approx.) 3.5.3.1 Back • 0” 3.5.3.2 Front • 0” 3.5.3.3 Sides • 0” 3.5.3.4 Above • Leave at least 1.25” between the top of the RFU and the ceiling or any overhead structure. • Leave at least 3” below the RFU.

The Telco entrance and Telco termination board should be located as close to the transmission line entry and AC service entrance as possible. This enables the individual ground leads to bond to a single point, with the least amount of distance between the ground leads. 3.9.1 T1 T1 lines are used to connect the RadioFrame System with the Mobile Switching Center (MSC). Each RFN customer iDEN/802.11b RFS site is typically fed with a single T1 line, and subsequently protected with a surge suppressor. The suppressor is located between the "smart jack" (maintained by the local telephone company) and the Channel Service Unit (CSU). The suppressor should be grounded downward directly to the master ground bus (MGB) using a #6 AWG green wire. The Telco board and the MGB should be mounted adjacent to each other on the same wall (the coax ground and power ground should also be at this same

Method of Procedure Pre-Installation 50 RFN_3.1 Beta location to achieve single point grounding). The Smart Jack and T1 suppressor are located on the Telco board near the T1 line entrance to the site. The CSU is located in main rack. The CSU is grounded to the main rack and subsequently to the master ground bar approximately 15 wire-feet away. 3.9.2 Power Cabling All electrical wiring for the site must meet the requirements of NEC and all applicable local codes. 3.9.2.1 AC Power Cabling This section describes only the AC power. All grounding shall limit the exterior connections to a single point. The transmission wire entrance for the GPS and the telco service and board must be installed on a common wall to have true single point grounding. Caution Facility AC wiring within junction boxes, receptacles, and switches shall be performed by a licensed and bonded electrical contractor. Personnel safety and liability hazards can result from AC wiring performed by installation personnel other than an electrical contractor. When an open equipment rack is used, hardwiring of power is not always possible. Mounting a dedicated simplex receptacle or receptacle assembly on the rack may be the most convenient method of supplying power, especially if multiple pieces of equipment are mounted on the rack. This is also a convenient way to install personal protection type 3 SPD devices (such as Motorola PN RLN4924A) to the equipment. These receptacle assemblies can be pre-manufactured and mounted to the top face of an equipment rack. Mounting can also use a fabricated power pole mounted between racks. Equipment that contains its own AC power supply is typically fitted with a standard grounded line cord. Where this equipment is used, the rack shall be equipped with a dedicated simplex receptacle or receptacle assembly. Use only the power cables provided by RadioFrame Networks. Use of any other cable is strictly prohibited and may void the warranty and/or cause electrical fire and damage. Caution Under no circumstances shall consumer-grade power outlet strips be used In any Installation. Extension cords of any type shall not be use for connecting line power to communications equipment.

RadioFrame System Pre-Installation RFN_3.1 Beta 51 AC input power Main Rack: The AC input power for the RFN iDEN/802.11b RFS solution shall be of 208/240 single phase and shall be coming off one designated 30 amp breaker. AC input power will be supplied to the Peco II rectifier panel. Remote ACUs: for 120VAC power, use the power cord provided (use of a different cord may void the warranty and/or cause electrical fire and damage). URUs: for 120VAC power, use the power cord provided (use of a different cord may void the warranty and/or cause electrical fire and damage). Circuit breakers Square D QO Plug-On type (30 Amp breaker) Rectifier frame feeds (for Peco II Rectifiers) Refer to the PEC 127NHL document for more information. 3.9.2.2 DC Power Cabling Use of UL approved cable is required; the suggested standard is UL1007. For RFN equipment, follow the cabling instructions described below for proper cable gauge, length, and color. Caution The power supply cord is used as the main disconnect device; ensure that the socket-outlet is located/installed near the equipment and is easily accessible. For -48VDC power, use only an AMP connector Part Number 350766-1 or equivalent using the following pinout: Pin Number Wire Connection 1 -48 Volts DC Return (black) 2 -48 Volts DC (red) 3 No connect

Method of Procedure Pre-Installation 52 RFN_3.1 Beta Wire shall be sized to carry a minimum of 11 Amps per these recommendations: Length of Run Minimum recommended wire gauge Up to 6’ 16 AWG 6’ - 10’ 14 AWG 10’ - 15’ 12 AWG 15’ - 24’ 10 AWG 3.9.3 Category 5 Cabling All components of the RFS are connected using standard CAT 5 cabling installed in existing raceways or conduits when available. Use only RJ45 (T568B) connectors for system components. The same is true for connecting the RFS to the iDEN Interface and the Customer LAN. If using a patch panel between RFS components, ensure the following: • Use only a CAT 5e- or CAT 6-rated patch panel. • Follow all TIA 568B standards. • Total impedance, end to end, cannot exceed 8 ohms. • Use only CAT 5e or CAT 6 wiring. Maximum length between RFS components shall not exceed 328’ (100 meters). A Universal Repeater Unit (URU) can be installed to extend the distance between any two RFS components to 656’ (200 meters). Up to 2 URUs can be used between any two RFS components to extend the distance to 984’ (300 meters). The maximum DC resistance allowed cannot exceed 26.2 Ohms per 1000 feet. Use plenum rated cable if the cable traverses through a plenum (open air) space. The proper installation of computer network cabling is critical to the safe and reliable operation of the computer network. It is recommended that standards developed by the Telecommunications Industry Association/Electronic Industries Association (TIA/EIA) and the Canadian equivalent (or equivalent standards in other countries) be followed. Applicable NFPA codes, local electrical codes, local building codes and other standards in this manual shall also be conformed to when installing computer network cabling. NOTE: It is recommended that a specialist in the installation of computer networks perform computer network cable installations. The specialist should have the expertise, knowledge of applicable local codes, and the test equipment required for a quality installation.

RadioFrame System Pre-Installation RFN_3.1 Beta 53 NOTE: This section cites standards from the American National Standards Institute (ANSI), the Electronic Industry Association (EIA), the Telecommunications Industry Association/Electronic Industries Association (TIA/EIA), and the Canadian Standards Association (CSA). Even in non-domestic installations, these standards should be adhered to. 3.9.3.1 Case Type CAT 5 Unshielded Twisted Pair (UTP), 100-ohm cable is the recommended cable type for computer network cabling, and will be the assumed cable type throughout this section. CAT 5 cable is preferred over CAT 3 and CAT 4 cables because of its ability to support 100Mbps (Megabits per second) systems and because of its better immunity to Electromagnetic Interference (EMT) and Radio Frequency Interference (RFI). Refer to ANSI/TIA/EIA-568-A, and CSA-T529 for more information. 3.9.3.2 Connecting Hardware UTP cables shall be terminated with connecting hardware of the same category rating or higher. This includes all connectors, punch blocks, cross-connect jumpers and patch cords. It is recommended that hardware used to terminate cables be of the insulation displacement (IDC) type. Modular connectors shall also be of the proper typed for the cable used; solid conductor cable uses a different connector than stranded cable. Refer to ANSI/TIA/EIA-568-A, and CSA-T529 for more information. 3.9.3.3 Cable and Connector Wiring Appropriate color-coding and jack pair assignments should be followed when wiring modular jacks, connectors, and cables. The same wiring standard shall be used throughout the cabling system. ANSI/TIA/EIA T568B is the recommended standard. The following illustration shows end views of an 8-pin Modular female jack for T568B with the pairs and colors identified. Refer to ANSI/TIA/EIA-568-A, and CSA-T529 for more information. Warning! Crimp all connector wiring completely. Ensure that all crimps have fully penetrated the protective coating on the wiring. Ensure that enough of the protective coating is left in place to fit inside the connector. Failure to follow these instructions may cause system failures to occur.

Every added junction point and cross-connect can decrease the performance of the network. Multiple appearances of the same cable at different locations, referred to as bridge taps shall be avoided. Each cable segment shall have only one source and one destination. Never untwist the twisted pairs of a CAT 5 cable beyond 1.3 cm (0.5 in.) from the point of termination. Untwisting the wires can decrease the cable's category performance rating and degrade system performance. Refer to ANSI/TIA/EIA-568-A and CSA-T529 for more information. Do not make sharp bends in CAT 5 cable. The bend radius for CAT 5 cable shall not be less than ten times the outside diameter of the cable. Bending the cable with a shorter bend radius can affect the electrical characteristics of the cable and degrade system performance. Refer to ANSI/TIA/EIA-568-A and CSA-T529 for more information. Do not pull a CAT 5 cable with excessive force. CAT 5 cable should not be pulled with a force greater than 110 Newtons (25 lbs force), or as suggested by the cable manufacturer. Pulling a cable with too much force can change the cable's electric characteristics and degrade its performance. Refer to ANSI/TIA/EIA-568-A and CSA-T529 for more information. Do not over tighten CAT 5 cable with cable ties or other supports. Over tightening cable ties or other supports can change the electrical characteristics of the cable and degrade the system performance. Refer to ANSI/TIA/EIA-568-A and CSA-T529 for more information. CAT 5 segment lengths shall not exceed 100 m (328 ft.). This includes 90 m (295 ft.) of building cabling and up to 10 m (32.8 ft.) of equipment cords, cross-

RadioFrame System Pre-Installation RFN_3.1 Beta 55 connects and patch cords. Of the 10 m (32.8 ft.) allowed for equipment cords, cross-connects and patch cords, a maximum of 3 m (9.8 ft.) should be used from the computer workstation to the information outlet. Refer to ANSI/TIA/EIA-568-A and CSA-T529 for more information. For simplifying installation and reducing cable runs, a single CAT 5 cable may be run from the equipment room hub to an additional hub in the computer workstation area for distribution to the individual computers. This can reduce the number of cables required between the equipment room and the individual computers. Refer to ANSI/TIA/EIA-569-A for more information. If cable segments need to be extended beyond 100 m (328 ft.), an additional hub may be installed. Each individual segment between hubs shall not exceed 100 m (328 ft.). Note that no more than the one intermediate hub shall be used. If the required distance is greater than, a specific cabling system shall be engineered. Refer to ANSI/TIA/EIA-569-A for more information. 3.9.4.1 NEC Compliance All RadioFrame Networks products and equipment are NEC compliant. 3.9.4.2 Local Jurisdictions Local jurisdiction codes shall apply and override any other requirements specified in this document. 3.9.4.3 Routes Consideration should be given to using some method of cable management and containment for runs of CAT 5 cable. Such methods can be dedicated cable runs, lay-in wireways, cable runways and conduits. Refer to ANSI/TIA/EIA-569-A and CSA-T530 for more information. CAT 5 cable shall not be installed in the same conduit, cable runway, outlet box, or similar device with AC power cables, unless separated by a barrier as allowed in NFPA 70, Article 800-52. Doing so can be unsafe and is likely to cause EMI onto the CAT 5 cable, causing network errors. Refer to NFPA 70, Article 800-52, ANSI/TIA/EIA-568-A, and CSA-T529 for more information. Precautions should be taken to avoid routing CAT 5 cable near sources of EM/RFI. Such noise sources may be electrical power wiring, dimmer switches, radio frequency transmitters, motors, generators, and fluorescent lights. Precautions may include, increasing the physical distance between the CAT 5 cable and the source of the EMI/RFI, installing the CAT 5 cable inside of a grounded metallic conduit, or use of a CAT 5100-ohm screened twisted pair cable as permitted by ANSI/TIA/EIA-568-A. Routing cables near sources of EMI/RFI can cause data errors and degraded system performance. Refer to ANSI/TIA/EIA-568-A and CSA-T529 T530 for more information.

Method of Procedure Pre-Installation 56 RFN_3.1 Beta Cables shall be separated by at least 5.1 cm (2 in.) from AC power conductors. Refer to NFPA 70, Article 800-52 for more information. CAT 5 cables installed in ducts, plenums, and other air-handling spaces shall be installed in accordance with other sections of this document and NFPA 70, Article 300-22. Also refer to NFPA 70, Article 645. CAT 5 cables installed in hazardous areas as defined in NFPA 70, Article 500 shall be installed in accordance with NFPA 70, Article 500 and any other applicable electrical and building codes. CAT 5 cable shall not be attached by any means to the exterior of a conduit or other raceway as a means of support. Refer to NFPA 70, Article 725-54 and NFPA 70, Article 800-52 for more information. Suspended ceiling support rods and wires may be used as a means of support for computer network cabling if used in conjunction with appropriate cable fasteners. Refer to ANSI/TIA/EIA-569-A and CSA-T530 for more information. CAT 5 cables shall not be laid directly on the tiles of a false ceiling. Refer to ANSI/TIA/EIA-569-A and CSA-T530 for more information. CAT 5 cables shall not be run from one building to another building. If the computer network needs to be extended to another building, a specific cabling system shall be engineered. Options for extending from one building to another may include the use of fiber optic cable or a T1. Computer network cabling entering and/or leaving a building shall be properly grounded and protected from surges as required elsewhere in this document. 3.9.4.4 Testing Every effort should be made to ensure a quality installation of the computer network cabling system. Even the best installation effort cannot guarantee a properly working system. It is therefore required that a computer network cabling system be tested for proper performance. The procedures and specifications in the TIA/EIA Telecommunications System Bulletin (TSB) 67 shall be used for this testing. TSB 67 has four primary parameters to test. Below is an overview of the four test parameters needed to assure a properly working system. Wire map The wire map test is used to verify wire pair to pin termination at each end of the cable and to check for installation connectivity errors. It is recommended that 100% of cables be tested using a testing tool such as Microtest® Microscanner™ Pro. (Be sure the tester can check for a “split pair” configuration). Each of the 8 conductors in the cable are tested for: • Conductor continuity to the remote end of the cable

RadioFrame System Pre-Installation RFN_3.1 Beta 57 • Shorts between any two or more conductors in the cable • Crossed pairs in the cable • Reversed pairs in the cable • Split pairs in the cable • Any other wiring errors in the cable Length The length test is used to determine the maximum physical length of the cable segments. The Microscanner™ Pro and many other models can be used to check cable, which are accurate within a few feet. The RFN guideline for cable length is 100 meters (approximately 328’ for less). Attenuation Attenuation is the measure of signal loss in the cable segment. Near-End Crosstalk (NEXT) loss NEXT loss is a measure of signal coupling from one wire pair to another within a single UTP cable segment. 3.9.4.5 Labeling Cabling shall be identified with a standardized, double-ended system to facilitate cable and equipment connection identification. (Refer to ANSI/TIA/EIA-606 for more information.) The label should show the following: • Equipment identification for each end of cable. • Connector reference designator for each end of cable. • Direction along the cable where terminating equipment is located. • Floor and room of the equipment. In general, the following considerations need to be observed in implementing a labeling system: • Labeling shall indicate the destination ends of the cable, in terms of equipment name and connector reference designator or name. This applies to connectorized, lugged, or punched-down cable terminations, regardless of the application (RF, audio, or control). • Labeling shall be imprinted on white opaque material (preferably plastic or plasticized paper) using indelible black ink.

Method of Procedure Pre-Installation 58 RFN_3.1 Beta • Labeling should wrap entirely around the cable. It should be secure enough to assure label retention if the cable is to be pulled through conduit. • Label placement shall be between 10 and 16 cm (4 and 6 in.) from each end of the cable (or the most logical point that would allow the label to be easily read). • Information printed on each label should be brief but clearly understandable. Because of limited space, abbreviations and acronyms should be used. If abbreviations are used, they should be industry standard. • All cables shall be properly labeled by the manufacturer as to the type, capacity, and approval ratings of the cable. 3.10 Main Rack Configuration The following illustration shows a typical main rack installation for a RadioFrame System. The main rack contains the iDEN Interface, the NCU and one ACU of the RadioFrame System, and the Power Plant. The rack must be an EIA-standard compliant rack, or equivalent.

RadioFrame System Pre-Installation RFN_3.1 Beta 59 Figure 17 Standard 19" 7’ rack configuration and power requirements for the RadioFrame System.

Method of Procedure Pre-Installation 60 RFN_3.1 Beta 3.11 RF Planning RF planning places a minimum number of RadioFrame Units in locations that will provide optimal coverage and voice quality. RF planning for the RadioFrame System takes into consideration anything that might affect RF propagation, including: • RFU locations, including coverage and mounting requirements, multi-story installations, and elevator shafts and stairwells • Simulcasting, including single-sector and multi-sector systems • Interference, including out-of-building emissions and in-building interference from macro systems • RFN recommends using three channels of separation For more information about site planning, refer to the RFN document, RF Planning Guide for RadioFrame iDEN Systems (990-1001-00). 3.12 Site Survey An informal site survey can be conducted to determine RFS equipment locations. Based upon the RFS square footage model, preliminary site designs are relatively easy to calculate prior to a formal site survey (refer to Appendix B “Site Survey” for an example of site survey questions and information). 3.13 Alarm Configuration Various alarms or sensors are installed within the RFN customer RFS site building. All alarm wiring terminates at the Environmental Alarm System (EAS) location within the main rack. The electrical contacts for the alarms must be dry contacts and normally remain closed (open on alarm). 3.14 Tools Required The RadioFrame System comes with all the parts necessary to mount each component of the system. This section describes all of the equipment necessary to install the RadioFrame System. 3.14.1 Hand Tools • #2 Phillips screw driver. • Optional: For RFU ceiling mounts, a drill with a 3/16” bit for use with provided wood screws, or a 9/32” bit and four ¼” bolts (not provided).

RadioFrame System Pre-Installation RFN_3.1 Beta 61 3.14.2 Laptop Computer A laptop computer is required to bring up the RFS. The laptop must be loaded with the following fully functional equipment (or equivalent): • Serial cable • Adapter for APC/NPC cards • Ethernet cables to connect to the RLIC: - crossover EIA/TIA 658A - straight through EIA/TIA 568B • EtherPeek • CD-ROM capability • FTP server (WFTPD) • Telnet and serial communications software (TeraTerm) • Administration rights to change settings on laptop 3.14.3 System Manager Software • Loaded on RLIC, which is used for the download • Up-to-date version loaded on the laptop (backup) • Loaded on a CD ROM (backup) • New versions can also be downloaded from RFN web site (backup) 3.14.4 IP Addresses for all cards in the RFS • RadioFrame LAN Interface Cards (RLIC) • Network Processing Cards (NPC) • RadioFrame Interface Cards (RIC) • Airlink Processing Cards (APC) 3.14.5 iSC-3 Configuration • Data fill of iSC (refer to RFN Recommended Data Fill, P/N 998-0100-00) • Method by which regional office identifies sector/cabinet positions 3.14.6 Test Equipment • Ethernet cable tester

RadioFrame System Installation RFN_3.1 Beta 63 4 Installation Following all construction work, both exterior and interior, the site and facility shall be in a suitable condition for the installation of communications equipment. In general, the following considerations need to be observed: • Interior of facility shall be free of excessive dust. • All refuse related to the installation tasks shall be removed. Consideration should be exercised when laying out a site to allow primarily for all code requirements for spacing, and then the most efficient use of space. Special attention shall be given to future expansion with regard to cable runway heights, electrical outlet placement, and equipment placement. The procedures described in this chapter assume the field technician or installer has knowledge of the installation techniques contained in the Quality Standards Fixed Network Equipment - Installation Manual (R56). Prior to performing the installation procedures, prepare the site with all associated antennas, phone lines, and other related site equipment. This information is covered in the Pre-Installation chapter. The main rack may already be installed, depending on the site configuration. 4.1 Main Rack and Supporting Hardware This section provides installation instructions for a cabinet already containing the iDEN Interface, RadioFrame Networks NCU and ACU, and the Power Plant. The procedure listed here is for permanently mounting the equipment cabinet within a site. The following procedures describe how to mount non-wheeled cabinets in a system site building. Be sure to read all of the procedures carefully to ensure a quality installation. 4.1.1 Main Rack The main rack must be secured to the floor for optimum stability. Since the main rack is very heavy, this procedure is written so that the rack is moved only once. Warning! Always use two or more persons whenever moving a cabinet. A fully configured equipment cabinet weighs approximately 800 lbs (360 kg).

Method of Procedure Installation 64 RFN_3.1 Beta Perform the following steps to properly install the main rack within the site building: 1 Measure the mounting location for the main rack within the row. 2 Carefully mark the mounting holes with a pencil, as indicated on the appropriate main rack footprint. 3 Drill the marked mounting holes to the appropriate depth of the mounting hardware with a hammer drill and bit. 4 Insert an anchor into the drilled hole. If necessary, tap the anchor into place using a hammer. 5 Remove the four screws securing the bottom kick panel to the front and back of the main rack. Remove the kick panel and set aside during installation. 6 Carefully move the main rack into the position indicated by the holes in the floor. Adjust and level the main rack as necessary to align the rack mounting holes with the pre-drilled holes in the floor. 7 Secure the main rack to the site floor with the locally procured mounting hardware. 8 If required, connect adjacent cabinets to each other using ganging hardware. 4.1.2 Auxiliary Equipment Auxiliary equipment for the main rack includes: • GPS antenna • Environmental alarm block • Mandatory alarms • Optional alarms • Surge arrestors • Grounding • Cable supports 4.1.2.1 GPS Antennas When locating the GPS antennas, install vertical mast (or antenna mount) at a location that provides a line of sight to as much of the horizon as possible. Solid buildings and overhanging trees will block the 1.575 GHz signal and cut down on the amount of sky visible and therefore the number of satellites the antenna can see. Satisfactory performance can be achieved with as much as 25 percent of

RadioFrame System Installation RFN_3.1 Beta 65 the sky being obscured. Reflecting objects such as air conditioners, walls, and metal surfaces may cause multi-path interference with the GPS signal and should be kept below 10 degrees above the horizon. • Minimum separation between GPS antennas is 4 feet. • GPS antennas should be installed at a height that allows for regional snow depth. The antennas may be installed on building tops utilizing mounting hardware designed to allow physical positioning aiming the antennas to the designated coverage area sectors. Downtilt brackets should be installed during initial installation of antenna at all sites other than omni configurations. Antenna installation shall be per the manufacturer’s instructions. All antennas shall be placed according to RF engineering information supplied by the RFN customer. The installation hardware supplied with the antennas by the manufacturer shall be used unless the RFN customer is supplying special brackets for unusual mounting. In order for sites to hand off correctly, each site’s GPS antenna must receive pulse signals from a minimum of one satellite. From that pulse the sites will set their “internal clocks” so that all sites will be synchronized. 4.1.2.2 Environmental Alarm Block Alarm wiring fitted with modular (8-pin Telco) connectors terminate at the EAS. All other connections are designed to terminate at a punch block.

Method of Procedure Installation 66 RFN_3.1 Beta Figure 18 Environmental Alarm Block Each of the site alarm contacts are normally closed and connected to the EAS through a 50-pin Champ cable that connects to a punch block. All alarm contact pairs must be dry (isolated from ground). Most alarm connections are inputs. Outputs provide a dry relay closure rated at 0.5 Amps, 30 Vrms or 60 Vdc, 10VA max. Alarm wiring for the main rack terminates directly to the EAS rear panel. Connect the alarm cable as shown in the previous illustration. Four outputs on the User Alarm/Control and System Alarm/Control connectors are available for customer-defined applications. Diode suppression of inductive surges is required if anything but a resistive load is connected to this output. Eighteen customer-defined alarm inputs are available on the User Alarm/Control connector. The alarms are reported to the Operations and Maintenance Center (OMC) by the respective alarm code. The OMC must be programmed with the proper alarm name corresponding to each code. All connections on User Alarm/Control and System Alarm/Control connectors must be defined and provided to the OMC to insure the effectiveness of monitoring those alarms. Backboard A wall mounted AC grade fire-rated plywood backboard (1/2” x 4’ x 4’) must be provided within the site. Reserve a two square foot area on the Telco backboard for dedicated system use. A 117 VAC dual receptacle outlet (3 prong) should be installed on or adjacent to the Telco backboard. This outlet can be used for accessories, such as modems and other AC powered devices. It may also be used as a general service outlet. 4.1.2.3 Mandatory Alarms RFN recommends site installation of the following alarms: Alarm Code Alarm Type EAS standard alarm connection 219 Intrusion alarm predefined input, site entry 220 High temperature predefined input, site high ambient temperature 221 Low temperature predefined input, site low ambient temperature 222 Smoke detector (120 VAC) predefined input, site smoke detector 242 Power Plant alarms: AC power failure 243 low DC voltage 244 high DC voltage 245 breaker alarm failure

RadioFrame System Installation RFN_3.1 Beta 67 Alarm Code Alarm Type EAS standard alarm connection 246 minor rectifier failure 247 major rectifier failure 4.1.2.4 Surge Arrestors T1 The T1 surge arrestor must be adequately grounded as outlined in the Quality Standards Fixed Network Equipment - Installation Manual (R56). The surge arrestor usually mounts near the demarcation (demarc) point. The cable connecting the surge arrestor to the Telco SmartJack should be locally procured, or should be provided with the surge arrestor. The cable connecting the iSC-3 to the surge arrestor is locally procured. GPS antennas All antenna feed lines should terminate with a suitable surge arrestor within 12” inside of the entry window. Each arrestor must connect to the master ground bar located below the entry plate. It is recommended that the arrestors be mounted to a mounting bracket to simplify grounding and cable installation. AC power (optional) An RFN customer-approved surge arrestor must be installed adjacent to the AC power panel. Very short wire lengths between the arrestor and the power panel are required for proper operation of equipment. 4.1.2.5 Grounding Within the site, ground the main rack with a single dedicated connection between the main rack and the master ground bar. The connecting wire must be a #2 AWG green-insulated copper wire. Use appropriate lugs (and split ring lock washers when possible) with an anti-oxidant grease applied for interior grounding connections and exterior secondary grounding connections. If lock washers are used, they should be placed between the nut and the lug to ensure the mechanical integrity of the connection. The washer must not be secured between the lug and the surface to which it is connected. Painted connections must be scraped clean before applying the anti-oxidant grease and lug. The main rack (ground bus) must be connected to the site ground using a single dedicated ground wire.

Method of Procedure Equipment Commissioning 82 RFN_3.1 Beta 5 Equipment Commissioning The procedures in this chapter describe how to conduct final checkout and system test procedures for each portion of the iDEN/802.11 RadioFrame System, including the iDEN Interface, the Power Plant, and the RFS. Following the successful completion of procedures described in this chapter, the RFS can be connected to the customer LAN as described in Chapter 6 “Connecting the RFS to the Customer LAN”. The procedures in this chapter are to be used in conjunction with troubleshooting and repair information provided in Chapter 7 Operations and Maintenance and the RFN document, Field Guide to the RadioFrame System. Together, these troubleshooting solutions and commissioning procedures provide the necessary information to isolate failures to a Field Replaceable Unit (FRU). This minimizes system downtime by quickly returning the site to normal operation. This chapter’s procedures check system functions and help isolate failures down to the FRU level. If a failure cannot be isolated after performing these tests, refer to Chapter 7 “Operations and Maintenance” for technical assistance information. 5.1 iDEN Interface Perform the following procedures described in the Gen 3 Site Controller System Manual, Motorola, 68P80801E30-O: Chapter Procedure Title 5 Final Checkout Final Checkout Setup Powering the Site Controller Rack Circuit Breakers 6 System Testing Site Controller Startup Sequence T1 Connection Test EAS Alarm Checkout GPS Status 5.2 Power Plant Perform the following procedures described in the PEC 127NHL Manual, PECO II, 438127NHL-IBWS-PD: Chapter Procedure Title 4 Initial Turn On and Acceptance Test Procedures Complete Operational Checkout Alarm Tests BTC Probe Compensation Test

RadioFrame System Equipment Commissioning RFN_3.1 Beta 83 Chapter Procedure Title Test Completion GPS Status 5.3 RadioFrame System After installation of all RadioFrame Networks equipment, including verification that each unit is receiving power, start the System Manager to complete the installation of the RadioFrame System. The System Manager automatically downloads information about each component in the RFS, including assigned IP addresses, sector information, port connections, and component status, as well as specifying default information that can be changed, or ‘configured’. To configure each system component, you will specify a device name, adding building/site location information for each component. Anytime an RFU port connection is moved or changed, or when an NPC or APC is moved to another slot within the same chassis unit (NCU and ACU, respectively), you must restart the System Manger to download the new information. For other RFS component changes, restarting is not required, however, RFN recommends validating that the port change is reflected in System Manager. When new releases of System Manager are provided, download the new release as described in section 7.1 Upgrading System Software. NOTE: During configuration, verify that the following information displayed in System Manager matches the Equipment Inventory. If any changes are made in System Manager, those changes must also be shown on the Equipment Inventory or site as-built documentation. • Physical location • IP addresses • Port connections • Sector locations 5.3.1 Start System Manager 1 Using a 9-pin serial cable, connect a laptop computer to the RS232 port on the front of the NCU. 2 Start the browser on the laptop, and enter the provided URL to start System Manager.

The iDEN Configuration page appears (see the following illustration). 2 Enter the new cabinet position for the specified RFS BR(s). 3 Select the Save Changes button to save your changes.

Method of Procedure Equipment Commissioning 92 RFN_3.1 Beta 5.4 Coverage Validation Once the components of the RadioFrame System have been configured, use iFTA-software, a laptop and an iDEN handset to check for regions of low signal strength. If increasing the transmit power from one or more local RFUs does not resolve the problem, adding another RFU is the surest remedy. 5.4.1 Detailed Building Plans—RF Modeling Testing by RFN has shown that simple Linear Attenuation Models (LAM) as discussed in COST 231, Chapter 4 section 4.7 “Indoor Propagation Models” work well provided they are used on a floor-by-floor basis. An attenuation coefficient of 0.62dB/m is recommended for dense, single-floor propagation, but this can double if concrete walls are present. 5.4.2 Measurement-based Estimate A battery-powered test transmitter can be moved between each RFU location and a handheld signal strength meter used to monitor RSSI. This method can be useful when RF penetration is desired through suspect walls or where wall construction data is lacking. Generally, this method provides good agreement when it is used to identify regions of poor coverage rather than to establish sufficient coverage zones. This is because it is usually inconvenient to duplicate an RFUs’ position during initial coverage surveys. 5.4.3 Floor Plan Estimate Oftentimes, only simple floor plans are available for the building in which the RFUs are to be installed. Without specifics about the building construction, such as interior wall, floor and ceiling construction, propagation models are of limited value. A measurement-based approach (discussed earlier) works well, but for simple buildings, installing RFUs at the candidate locations and then testing the results will likely be adequate. If regions of poor coverage are found, transmit power can be increased or if necessary, additional RFUs added. 5.5 Site Acceptance Guidelines 5.5.1 Site As-Built Documentation As-built documentation consists of the original site development documentation with post-installation information. On the job, installers use site development documentation for reference, to make notes, and to document completion of each step of the installation.

RadioFrame System Equipment Commissioning RFN_3.1 Beta 103 5.6.1.10 Validation of ‘Unable to Key BR’ Alarm While the RFS is operating, any system component, from the NCU to the RFU, will be disconnected, and the OMC will be monitored to validate the generation of the “Unable to Key BR” alarm by the RFS. The RFS provides fault alarming and isolation within System Manager for individual components, which consists of detecting catastrophic faults that prevent an RFS component from responding to a periodic “ping”. All fault alarms generated by the RFS are received at the OMC via the iSC. The “Unable to Key BR” alarm will appear at the OMC as minor, major, or critical as follows (for more information about alarms, refer to section 7.5 Alarm Resolution Procedures): ‘Unable to Key BR’ alarm severity Indication minor An iDEN RadioBlade or 802.11b RAP has failed. major An RFU has failed. critical A card in a chassis unit has failed (except for the RLIC, which is responsible for returning the alarm information.) 5.6.2 Rectifier & AC Power Alarms For information on conducting an Rectifier functionality test, refer to the Peco II document: Peco II 127HNL. 5.6.3 iSC-3 Functionality Test For information on conducting an iSC-3 functionality test, refer to the Motorola document: Gen 3 Site Controller System Manaual, 68P80801E30-O.

Method of Procedure Connecting to the Customer LAN 104 RFN_3.1 Beta 6 Connecting the RFS to the Customer LAN Once the RadioFrame System has been installed, commissioned, and all iDEN Acceptance Test and System Functionality procedures have been successfully completed, the RFS can be connected to the Customer LAN. Once the LAN has been physically connected, the RFS must be globally configured to support the LAN. Individual RAPs can also be configured, overriding certain global configuration options. 6.1 Connect the NCU to the Customer LAN In an 802.11b installation, RAPs are installed in each RFU supporting the WLAN. Once the RFS has been physically connected to the LAN, use the System Manager to configure the RFS to support the WLAN. 1 Connect Port 2 on the front of the NCU to the customer’s local area network using an RJ45-to-RJ45 CAT 5 cable (see the following illustration). Figure 32 Connect Port 2 on the front of the NCU to the customer’s LAN. 6.2 Configure the RFS Global 802.11 Services This section describes how to configure the RFS global, or system-wide, 802.11 configuration settings. First, start the System Manager, then configure the following five items: • Service Set Identity (mandatory) • WEP Encryption (optional) • Enhanced Security (optional) • User Access Control (optional) • Add/Remove MAC Addresses (optional)

RadioFrame System Connecting to the Customer LAN RFN_3.1 Beta 105 1 Start System Manager and log in to the RFS. Start your browser, and enter the provided RFS URL to start System Manager. Enter your User Name and Password to log in to the RFS. 2 Select the System Configuration tab. 3 Select the 802.11 Global Configuration link under Other Configure Options. The following screen appears. You must choose a security method for the RFS, or the RFS will not work. 4 Select “MAC address access control”. The 802.11 Global Configuration page appears (see the following illustration). The 802.11 settings are divided into five groups: • SSID • WEP Encryption • Enhanced Security • User Access Control • Add/Remove MAC Addresses. When you make changes to any of these five settings, you must save the changes for that section using the Save Changes button for that setting. 5 For SSID, enter up to 32 alphanumeric characters to identify the Service Set Identity for the RFS, and select Save Changes to save your changes. You must enter an SSID in order for the RFS to have 802.11 capabilities. Typically, the SSID reflects the owner of the RFS. By default, the owner is RFN Customer. For more information, refer to section 6.2.1 Service Set Identity (SSID). 6 For WEP Encryption, RFN recommends that you set Encryption to “On”. In this case, you must also define the four WEP keys. To enter a WEP Key, first select the radio button next to the text box of the WEP key you want to enter or change. Enter each WEP key in hexadecimal format consisting of five pairs of hex digits. Five pairs of hex digits form a 40-bit binary string, which is the standard length of a WEP key. Only one WEP Key can be selected at a time (the radio button is selected). Then, choose

Method of Procedure Connecting to the Customer LAN 106 RFN_3.1 Beta one of the four keys to be used for RAP identification (select the radio button of the key you want to use). For Shared Key Authentication, RFN recommends that you leave this option disabled, that is, do not select the option. When you have set all the WEP Encryption options you want, select Save Changes. Refer to section 6.2.2 WEP Encryption for more information on using WEP Encryption settings. Figure 33 Each global 802.11 configuration setting has a separate “save” button.

RadioFrame System Connecting to the Customer LAN RFN_3.1 Beta 107 7 For Enhanced Security, RFN recommends that you select “On” to prevent RAPs from broadcasting their SSIDs. Then select Save Changes. For more information, refer to section 6.2.3 Enhanced Security for more information on using this setting. 8 For User Access Control, RFN recommends that you select “On” to control which devices will have access to the customer LAN via the RFS. Then select Save Changes. For more information, refer to section 6.2.4 User Access Control for more information on using this setting. 9 For Add MAC Address, enter the MAC address of each device that will be authorized to the use the customer LAN. You can enter MAC addresses one at a time, or copy them from a database or other file (Add MAC Addresses from file). You can also remove the entire list of MAC addresses (Remove All MAC Addresses), or save the list of MAC addresses to a file (Save MAC Addresses to File). For more information, refer to section 6.2.5 Add/Remove MAC Addresses for more information on using these options. 6.2.1 Service Set Identity (SSID) The only mandatory RFS 802.11b configuration setting is the Service Set Identity (SSID). The SSID must be configured in all installations where 802.11b RadioFrame Access Points are installed. If the SSID is not configured, the 802.11b capability will not be available. The SSID is necessary because, unlike wired LANs, a device which is part of an 802.11 LAN may be within radio range of multiple “groups” of 802.11 stations. In order to isolate stations in one group from stations in another group, the SSID was created. It is an 802.11-only construct, which does not exist for any other type of LAN. The SSID identifies a collection of 802.11 stations for the purpose of communication as a group. The SSID is 1 to 32 characters in length. Typically, the SSID reflects the owner of the RFS. By default, the SSID is ‘RFN Customer’. This way, users can distinguish their LAN from any other 802.11 LAN which might physically overlap their area. For example, the SSID “RFN_Customer_Marketing” could provide the Marketing department at the RFN customer with its own distinct wireless LAN. Other departments within the RFN customer, such as “RFN_Customer_Operations”, might be in close proximity to the Marketing department. The staff in the two departments would both have 802.11 access to the company LAN, but their access would be provided via different RAPs, based on which SSID they use.

Method of Procedure Connecting to the Customer LAN 108 RFN_3.1 Beta 6.2.2 WEP Encryption The Wired Equivalent Privacy (WEP) encryption technology is defined in the IEEE 802.11 standard, and is intended to provide the same quality of privacy and access control for an 802.11 LAN as is provided for a wired LAN. That is, a WEP-protected 802.11 is should be no easier to infiltrate or eavesdrop than would be on a wired LAN. Any LAN (wired or wireless) can be made more secure and private by applying additional security measures (such as encryption, centralized strong authentication, firewalling, etc.). The difference between a wired LAN and a wireless LAN, however, is that without including encryption of user traffic and encryption-based access control, a wireless LAN is inherently less secure than a wired LAN, all other things being equal. 6.2.2.1 Encryption (On/Off) WEP encryption is enabled or disabled by selecting “On” or “Off,” respectively. When “Off” is selected, all other items related to WEP encryption are disabled (WEP Keys and Shared Key Authentication), and need not be configured. When “On” is selected, then the WEP keys must be entered. 6.2.2.2 Shared Key Authentication When Shared Key Authentication is enabled, or “checked,” the RAPs will require client devices (such as laptop computers) to prove their authenticity by answering a challenge from the RAP. This challenge (authentication protocol) can be answered correctly only if the client device “knows” the WEP keys configured into this RFS. NOTE: RFN does not recommend the use of Shared key authentication, because the messages used to accomplish this authentication may provide information to eavesdroppers as an aid in cracking the WEP encryption on future messages. The ability to enable or disable Shared Key Authentication is provided mainly for compatibility purposes. Some client adapters may require Shared Key Authentication whenever WEP encryption is enabled. If this is not the case with the client adapters used in your location, then it is best to leave this setting disabled. This does not compromise security, however, because with WEP encryption enabled, the RAP will not accept traffic from 802.11 client devices unless the traffic is encrypted. 6.2.2.3 WEP Keys When WEP Encryption is enabled, you must enter values for the four WEP keys in order for the RFS 802.11 implementation to function. WEP Keys are used to encrypt 802.11 traffic that is transmitted by a RAP. Each WEP Key has a radio button. When you select the radio button, you can enter, change, or delete information for that key only. Each WEP key consists of

RadioFrame System Connecting to the Customer LAN RFN_3.1 Beta 109 five pairs of hex digits forming a 40-bit binary string, which is the standard length of a WEP key. Only one WEP Key can be selected at a time. The selected key is used to encrypt 802.11 traffic that is transmitted by a RAP. However, any of the four keys may be used by client devices for their transmissions. The determination of which key is used by a client device is performed at the client device, usually in a manner similar to the way the RAP is configured. 6.2.3 Enhanced Security Enhanced Security provides another layer of protection for the RFS 802.11 implementation. When enabled, or “On”, this setting prevents RAPs from broadcasting their SSID information. This helps to prevent unwanted users from accessing the customer’s WLAN. When disabled, or “Off”, any system can ‘see’ the SSID of RAPs in the customer WLAN. 6.2.4 User Access Control The RFS provides the ability to restrict access to the customer LAN to certain pre-authorized devices. RFN recommends setting the User Access Control option to “On” to provide a means to identify those devices that are authorized to communicate over the customer’s LAN via the RFS. When this option is disabled, set to “Off”, any client device may associate with the RFS. Devices are identified by a number that is programmed into the 802.11b network interface installed in the device. For instance, laptop PCs typically use a PCMCIA card plugged into the laptop’s PCMCIA bay to access an 802.11 network. Every 802.11b PCMCIA card comes from the manufacturer with a unique serial number programmed into it. No two 802.11b devices are ever manufactured with the same serial number. In IEEE 802 networking terminology, this serial number is called the MAC address (Media Access Control address), an addressing mechanism that is present in all types of IEEE 802 LANs. The MAC address is typically represented as six sets of hexadecimal (base 16) numbers, with two hexadecimal digits in each set. The following is an example of how a MAC address may be written: 00:04:16:A3:29:B7 Authorized MAC addresses/devices are listed below the User Control option. To learn how to add and remove MAC addresses, read the following section 6.2.5 Add/Remove MAC Addresses. When you are done adding and removing MAC addresses, you’ll select the Save Changes button under User Access Control. 6.2.5 Add/Remove MAC Addresses Start by collecting a list of MAC addresses for all user devices that will be authorized to access the customer’s LAN via the RFS 802.11. It is best to keep a

Method of Procedure Connecting to the Customer LAN 110 RFN_3.1 Beta permanent list (on paper, in a spreadsheet, or other computer storage) that includes each MAC address and a description of the device, including the name of the person who owns the device, etc. Also refer to section 6.4 Viewing WLAN User/RAP Associations, later in this chapter. 6.2.5.1 Adding MAC Addresses MAC addresses are added to the list of authorized client devices in one of two ways: one, you can enter the addresses one at a time, or two, you can enter the MAC addresses into a text file and “upload” this list into the MAC address database. To add an individual MAC address, enter it in the box labeled Address. Enter each MAC address in the format described above, that is, six pairs of hexadecimal digits (for example 00:04:16:A3:29:B7). The alphabetic values of hexadecimal digits—A,B,C,D,E,F—may be in either upper case or lower case. For Name, enter a meaningful device name or identifier, or the name of the person who owns the device, then select Add Address. To add MAC addresses from a file, either enter the file name under Add MAC Addresses from File (including drive letter and full pathname), or select the Browse… button to locate the file. Then, select Add. This appends the MAC addresses from the file to any other MAC addresses already entered into System Manager. TIP Add one or two individual MAC addresses, then save those MAC addresses to a file (see “Saving MAC Addresses” later in this section). Then open the text file and copy the saved address(es) to a new line in the file, and edit each line to specify a different client device and MAC address. This way, you can create your list of authorized devices, save the file as a backup, and upload the file into the System Manager knowing that the format of the text file will be acceptable to the System Manager. 6.2.5.2 Removing MAC Addresses To remove a MAC address, select the delete option listed next to the MAC address you wish to remove. To remove all MAC addresses, select the Remove All Addresses button under Remove All MAC Addresses. 6.2.5.3 Saving MAC Addresses When all additions or removals have been completed, select the Save Changes button at the bottom of the User Access Control section. This will record the MAC addresses and the User Access Control setting and activate them. To save the entire list of MAC addresses to a file, enter a file name in the text box under Save MAC Addresses to File, then select the Save to File button.

RadioFrame System Connecting to the Customer LAN RFN_3.1 Beta 111 6.3 Configuring an Individual RAP RadioFrame Access Points (RAPs) provide the 802.11b wireless interface between the RFS and the corporate local area network (LAN). Typically, all RAPs in the RFS are configured at one time using the 802.11 Global Configuration options. These global settings can be overridden by changing configuration information for individual RAPs. Individual RAPs can also be isolated from further global changes as well. NOTE: WEP Encryption and Enhanced Security settings override global 802.11 settings. Typically, changing these settings is done to isolate the RAP for testing. 1 Using the System Configuration tab, drill down to the RFU that contains the RAP(s) you want to configure, and then select the RAP icon to display its configuration page. 2 For SSID, either leave the globally configured SSID name as it is, or enter up to 31 alphanumeric characters to change it.

Method of Procedure Connecting to the Customer LAN 112 RFN_3.1 Beta The SSID you enter must be a valid SSID that is recognized by System Manager. 3 For Channel, type 1, 6, or 11 to specify the channel to be used by the RAP. At the time of shipment, all RAPs are set to Channel 6 by default. Channel numbers can only be changed at the RAP level—channels cannot be changed using global settings. If a 3-channel frequency plan is implemented, RFN recommends using channels 1, 6, and 11 (in countries where these channels are permitted). 4 Select ‘Save Changes’ to save the SSID and Channel settings. 5 When WEP Encryption is disabled or “Off”, all other items related to WEP encryption are disabled (WEP Keys and Shared Key Authentication). When “On”, a WEP Key other than the globally configured WEP key can be selected. Also, Shared Key Authentication can be enabled or disabled, “checked” or “unchecked” respectively. For more information about Shared Key Authentication, refer to section 6.2.2.2 Shared Key Authentication. RFN recommends that RAP WEP Encryption settings be set globally rather than individually. RAP WEP Encryption changes remain until changes are made to the global 802.11 settings. 6 Statistics lists information about the functioning of the RAP, including: Statistic Description Transmitted Frames Number of frames transmitted by the RAP Received Frames Number of frames received by the RAP FCS Errors Number of FCS errors WEP Undecryptable Frames Number of frames that could not be unencrypted Transmit Failed Number of failed transmissions Multiple Retries Number of retries attempted IP Address IP address of the RAP MAC Address MAC address of the RAP 7 For Enhanced Security, select either “On” or “Off”, and then select Save Changes.

RadioFrame System Connecting to the Customer LAN RFN_3.1 Beta 113 6.4 Viewing WLAN User/RAP Associations To view clients and their associated RAP(s), select the Active MAC addresses link on the 802.11 Global Configuration page. For each RAP, the Active MAC Addresses page lists each user associated with the RAP, including the user name (Description) and the IP address of the workstation or piece of equipment. Information is sorted by the RAP IP address. To view the number of users supported by each RAP, select the Active DataHosts and Associations link at the top of the 802.11 Global Configuration page. The Active DataHosts page identifies the location of each RAP by RFU and ACU, and displays the number of users associated to the RAP. You can view the configuration for each RAP, RFU or ACU by selecting the link for that component. This information can be used to analyze the load distribution in the WLAN RadioFrame system.

Method of Procedure Connecting to the Customer LAN 114 RFN_3.1 Beta 6.5 Verifying the Wireless LAN (802.11b) Installation Verifying the LAN installation requires a laptop that has 802.11b internally or a client card that plugs into the PCMCIA port. 1 Associate with a RAP in the RFS by matching the SSID on the client (laptop) and the SSID that is configured in the System Manager. 2 Setup a static address on the client to communicate with the RFS (refer to the appendixes for a list of default IP addresses for the RFS). 3 Once associated, open a command window and ping the RLIC IP addresses to confirm that the client is properly associated with the RAP (this also confirms connectivity up to the RLIC). 4 Once associated, navigate to a few Internet addresses. This requires that the Administrator correctly configure their network for this navigation.

RadioFrame System Operations and Maintenance RFN_3.1 Beta 129 7.5 Alarm Resolution Procedures The RFS provides fault alarming and isolation within System Manager for individual components, which consists of detecting catastrophic faults that prevent an RFS component from responding to a periodic “ping”. Depending on the severity, alarms are sent to the OMC via the iSC-3. All alarms passed to the OMC use an Alarm Code, such as 39005, which uses the event description “Unable to key BR”. This section describes: • How to view alarms in System Manger, • OMC alarm code and severity levels, and • System Manager alarms and resolution procedures. 7.5.1 Viewing System Manager Alarms System Manager displays system-related errors. Only some of these errors are sent to the OMC. 1 To view alarms and other system-related errors in System Manager, select the Alarms tab. The Alarms Log displays RFS alarms, listed by Time of occurrence (including the date), in a sequence of 200 alarms at a time—No. (see the following illustration). Approximately 25 alarms are visible at any one time. At the bottom of the page, you can see which alarms are currently displayed, in this case, 99 through 118 of 118 alarms. NOTE: If the Alarms page is empty, System Manager is still loading the page. 2 To display alarms that have scrolled out of view, select first, prev, next, last or all at the bottom of the alarm page, then enter a value in the Show text box and press enter. For example, to view the first 20 alarms, click first and type 20 in the text box, then press Enter. To return to the bottom of the list of alarms, select last and type a value in the text box.

Method of Procedure Operations and Maintenance 130 RFN_3.1 Beta Figure 35 Alarms are listed up to 200 at time and continue to scroll as events occur. For each Alarm, System Manager displays the alarm description and whether the alarm is new (Set) or has been cleared (Clear). The same alarm will continue to be listed as a set alarm until it has been cleared. If an alarm is not cleared, it will be sent to the OMC (see “System Manager Alarm Descriptions” later in this section). Other alarms might occur before an alarm clears, so the ‘set’ and ‘clear’ for the same alarm do not necessarily appear in sequence. The Alarm Tag uniquely identifies each alarm using either the actual IP address or hex digits to represent the IP address of the affected component. In the latter case, the last four digits of the alarm tag represent the last two sets of digits of the IP address of the component. For example, 0xc0a80679 represents xxx.xxx.06.121. The IP address of the board generating the alarm is shown under SrcAddress, or ‘source address’. Board Type identifies which board within a chassis unit is affected (APC, CRIC, etc.). For these alarms, select Click for chassis link to display the page for that component.

RadioFrame System Operations and Maintenance RFN_3.1 Beta 131 NOTE: When troubleshooting alarms that require assistance from RadioFrame Networks, you’ll need to provide the data displayed in the Alarm Data and DbgFlgs fields. 7.5.2 OMC Alarm Code and Severity Levels All RFS alarms sent to the OMC use an Alarm Code, such as 35009 (see the following table). The Event Description for this alarm is ‘Unable to key BR’. The severity level—minor, major or critical—indicates which RFS component has been affected (see the second table below).
