3 Product descriptionThe DIB-R5 base station family is a constituent of the TETRA mobile radio systemACCESSNET-T IP and ensures the powerful and reliable mobile radio coverage of a spe-cific area. Trendsetting TETRA Release 2 and TETRA Enhanced Data Service (TEDS)support make the DIB-R5 extremely attractive for all scenarios in which a high degree ofavailability as well as high speed data are a must. The TEDS data transmission allowstransferring up to 150 kbit/s (gross bit rate) securely and reliably via the air interface.Figure 4: DIB-R5 familyThe different variants of the DIB-R5 base station family meet the customer and networkrequirements in a perfect way. The following variants of the DIB-R5 are available:nDIB-R5 advancedThe DIB-R5 advanced offers up to eight TETRA carriers with cavity combiner.DIB-R5 advanced consists of one or two equipment racks depending on the numberof carriers.nDIB-R5 compactThe DIB-R5 compact offers up to two TETRA carriers with hybrid combiner.DIB-R5 compact is suitable for space-saving installation in existing 19" equipmentracks.The hardware design of DIB-R5 features a modular layout. This allows hardware compo-nents to be replaced or added during ongoing operation.Product descriptionDIB-R5 advanced19Operation Manual 90DIBR5advancedOM02 - 1.0
In each equipment rack DIB-R5 advanced offers space for four TETRA Channel Units(CHU), which are each providing one TETRA carrier. By using a second equipment rack,up to eight carriers are supported. Thus offers DIB-R5 advanced a maximum of 32 radiochannels to the radio subscribers that can be used simultaneously. To increase the avail-ability, DIB-R5 advanced can be equipped with different redundancy options to avoid"Single Points of Failure". On the hardware side, the transceivers, control unit and voltagesupply can be designed redundantly. Furthermore, additional software-based redundancyoptions are available that further increase the reliability of features.DIB-R5 advanced supports different system configurations of the antenna couplingsystem, including motor-tuned cavity combiner. This enables individual and fast remotefrequency change. In addition, DIB-R5 advanced supports for optimal reception triplediversity. This optimizes the radio characteristic of the base stations and reduces thenumber of base stations that are required for covering a certain area.DIB-R5 advanced can be configured depending on customer requests and networkrequirements and expanded e.g. through additional carriers. This allows the mobile radionetwork to be adapted accordingly to meet new requirements and protect the currentinvestment.For time synchronization, the DIB-R5 advanced compact can be operated optionally withsatellite-based synchronization, e.g. GPS, Galileo and Glonass (Global Navigation Satel-lite System, GNSS).The continuous operation is also supported without satellite-basedsynchronization sources. This allows a reliable operation even in underground areas orwithin buildings without the need of using an antenna for the reception of a satellitesignal.The following figure shows the front view of the DIB-R5 advanced with four TETRAChannel Units (CHU) and DUPLEXER.

The concept of designingsystem functions, function blocks, network elements and connection routes redundantly,may be required to ensure location reliability and system reliability. Location and systemreliability refers to the capability of the network to perpetuate the operation of the overallsystem, even if one location or route drops out completely or partially (due to technicalfailure, natural phenomena, acts of terrorism etc.).The system technology allows flexible network structures and scalable redundancy solu-tions that account for the different requirements for availability and capacity within ancomplete network.If the DIB-R5 advanced should be isolated from the rest of the network, it still providesmost of its features in local fallback operation. Especially security-related features likeauthentication and air interface encryption are supported. Hence, DIB-R5 advanced ena-bles a fully functional fallback operation and full redundancy for the important compo-nents transceiver (CHU), control unit (BSCU) and voltage supply.The following chapters describe the available redundancy options in conjunction withDIB-R5 advanced:nÄ Redundant main control channel (MCCH)nÄ Transceiver redundancynÄ Controller redundancynÄ Fallback operationnÄ Stand-alone operationnÄ Redundant VAC voltage supplynÄ Redundant connection to the transport networknÄ Redundant synchronization (GNSS, PTP)Product descriptionRedundancy optionsDIB-R5 advanced60 Operation Manual 90DIBR5advancedOM02 - 1.0
The redundancy options can be combined with each other.3.5.1 Redundant main control channel (MCCH)By redundant main control channels (MCCH) the operation of a base station is guaran-teed even if the carrier with the MCCH drops out or should be disturbed.If the carrier that provided the main control channel last drops out, an alternative carrierwill take on this task. The MCCH is thus transferred. This will maximally be repeated asoften as the number of carriers that are available at the base station. In this case, thereplacement carriers for the MCCH keep on sending on their original frequency, not onthe frequency of the failed carrier. This frequency change is useful especially when inter-fering carriers affect the MCCH frequency that was being used up to that point.Irrespective of the number of carriers, each radio cell has only one MCCH, via which themobile stations receive information, e.g. on adjacent radio cells. As a rule, the firstchannel of the first carrier of a base station is used as the MCCH, the three remainingchannels of that carrier and all the channels of all the other carriers are used as voicechannels or the Packet Data service. Redundant MCCH are enabled by default and applyto all the base stations with more than one carrier.3.5.2 Transceiver redundancyTo increase the system stability of carriers or to ensure the Base Station Function (BSF),as many as two redundant transceivers can be used in one base station. If one trans-ceiver fails, these spare transceivers ensure the radio coverage with the frequency of thefailed transceiver. Transceiver redundancy is mostly used in cases, in which only a fewfrequencies are available.3.5.3 Controller redundancyThe controller required for operating a base station can be designed redundantly. In thiscase, two BSCUs (Base Station Controller Units) are used, whereby one BSCU is inoperation and the other is kept ready for operation (standby). In case of a failure of theactive BSCU or its ethernet connection, the standby BSCU is automatically switched toactive and takes over its function. This ensures continued operation of the base station.3.5.4 Fallback operationThe radio coverage of base stations is also ensured if the base station loses the connec-tion to an IP Node (IPN) with Switching Controller Function (SCF). In this case, the basestation changes to fallback operation. In fallback operation, the base station in its radiocell still maintains the Base Station Function (BSF). Even in fallback operation, authenti-cation and authorization validation are ensured since the corresponding subscriber dataare stored in the base station.Product descriptionRedundancy options> Fallback operationDIB-R5 advanced61Operation Manual 90DIBR5advancedOM02 - 1.0
The connection to other network constituents is not possible in fallback operation, the fol-lowing services and features, however, are available locally:nGroup callsnIndividual calls (semi-duplex and duplex calls)nTransmission of SDS and status messagesnClass 2 and class 3 air interface encryption (encrypted voice and data communica-tion)nAuthentication (with respect to the base station)nPriority calls, emergency calls, pre-emptive priority callsnQueue, depending on the priority level of the callnRejection of a call from/to an unknown subscribernRejection with the reason "busy" if the subscriber is already making a call or the pri-ority of the incoming call is minornConfigurable call time limitnInactivity timer (ending semi-duplex calls after the configured inactivity time hasexpired)Fallback operation is the emergency operating mode of base stations in networks withcentralized switching architecture. The operating mode is signaled to the mobile stationsand taken into account by them for the cell selection.3.5.5 Stand-alone operationThe radio coverage of base stations with Switching Controller Function (SCF) in networkswith distributed switching architecture continues to be ensured if they lose the connectionto all other network constituents with SCF. In this case the base station switches to stand-alone operation.In stand-alone operation, the base station in its radio cell will perpetuate the Base StationFunction (BSF) as well as all the other local services and gateways (Application Gateway(AGW) and/or Packet Data Gateway (PGW)). As opposed to fallback operation, in stand-alone operation Call Detail Records (CDR) will still be generated.Stand-alone operation is the emergency operating mode of base stations in networks withdistributed switching architecture. The operating mode is signaled to the mobile stationsand taken into account by them for the cell selection.Depending on the project require-ments, the signaling can be switched off upon demand.3.5.6 Redundant VAC voltage supplyFor the reliable voltage supply, DIB-R5 provides two redundancy options for VAC voltagesupply to ensure operation of the base station at all times:nÄ Redundant rectifier modules (Power Supply Module, PSM)nÄ Redundant voltage supply feedsBoth redundancy options can be combined for the highest possible reliability.Product descriptionRedundancy options> Redundant VAC voltage supplyDIB-R5 advanced62 Operation Manual 90DIBR5advancedOM02 - 1.0
3.5.6.1 Redundant rectifier modules (Power Supply Module, PSM)The voltage supply continues to be ensured through redundant rectifier modules (PowerSupply Module, PSM) and ensures the operation of DIB-R5 if one PSM should fail. Theactive and the redundant PSMs are all in operation in this case and divide the loadamong them. In case of a failure, the load on the remaining PSMs is increased accord-ingly.In the combination with redundancy option "Redundant voltage supply feeds", two PSMseach are supplied by one voltage supply feed.3.5.6.2 Redundant voltage supply feedsThe voltage supply continues to be ensured on site by the redundant voltage supplyfeeds and secures the operation of DIB-R5 even if a feed should fail or fall below therequired voltage range. This is particularly meaningful in difficult environments in which,for example, the infrastructure on site is unreliable. With this redundancy option, onePower Distribution Module (PDM), two in case of redundancy, is always supplied by avoltage supply feed.If this redundancy option is selected, a second voltage supply feed must be taken intoaccount in the location planning.3.5.7 Redundant connection to the transport networkWith the redundant connection to the transport network, the connection to all networkcomponents continues to be ensured in case of a failure of the IT infrastructure (e.g.router).3.5.8 Redundant synchronization (GNSS, PTP)The clock and time signals required for the synchronization of base stations are beingobtained in parallel via a connected GNSS antenna and as an alternative via the Preci-sion Time Protocol (PTP). If the satellite signal should no longer be available due toexternal influences, a switch is automatically made to the network time.Product descriptionRedundancy options> Redundant synchronization (GNSS, PTP)DIB-R5 advanced63Operation Manual 90DIBR5advancedOM02 - 1.0
