Connecting the analog ground in only one point avoids ground currents from powersupplies and other high current circuitry from creating noise in the analog circuitry. This common point should be locatedwhere the analog supply voltage (VANA) is generated (at filter (A), or regulator (B) depending on implementation).5V VANA12VVANARegulatorBA

DM15/25 Integrator’s Manual 29 OF 386.4.3 Analog ground vs. AGNDThe AGND signal output from the module is not a ground. It is an analog reference, which isconnected to the main ground used by the module in one place inside the module. It should notunder any circumstances be used as a ground or connected to a ground in the application.AGND must be treated as a signal. Together with ATMS and AFMS it creates a semi differentialinterface.The analog ground shall be used as ground plane for the analog circuitry of the application. Itshould not be connected to the AGND signal output from the phone module.6.4.4 Microphone pathAn application using the analog audio interface must re-reference the signal from its own internal BIAS to AGND receivedfrom the module.The figure below shows an example of a microphone implementation.The microphone should preferably be connected to its pre-amplifier differentially, which will minimize noise picked up alongthe way from the microphone to its amplifier. If the impedance is the same on both microphone lines, and the lines are run inparallel, the same amount of noise is picked up on both lines. This noise is then removed in the differential amplifier stage.0-+0R2R2R3R3R1R1VCCC2C2C3C30-+0R4R4R5R5C5C5<=1kBIAS>=2.2uF ATMSAGND>=2.2uF++

The antenna connector of the module is surface mounted, micro miniaturesnap-on MA/-COM connector (P/N 2367-5002-54). A wide variety of compatible mating connectors areavailable. Pigtail assembly (P/N 9960-2100-24), and the inter-series cable assembly (P/N 9960-4100-XX) fromM/A-COM are two options using pre-assembled cables. Another mating option is a right angle crimp jack fromM/A-COM that uses standard RG-type coaxial cable. Custom cables assemblies can be manufactured toindividual requirements using standard off-the-shelf coaxial cable and mating connectors (TNC, SMA, etc.) witheither RG-178 or RG-316 size M/A-COM connectors. Since the mating connector can rotate through 360o, theapplication developer has maximum flexibility for routing the RF coax assembly. The total height of the matedpair using M/A-COM pre-assembled RF connectors is 0.12 inches. The mated pair height using the right anglecrimp jack is approximately 0.290 inches. Physical dimensions of the two module connector types are shownbelow. The pigtail and the right angle crimp.The physical dimensions of the connector are shown in the drawing below.Electrical performance parameters are valid only when the terminating impedance at the output of the antennaconnector exhibits a VSWR of less than 2:1 for all phase angles in the frequency band of operation. HighVSWR loads at the antenna connector adversely affect current consumption, linearity, and power efficiency ofthe module and may prevent operation or cause internal damage.The RF performance of the DM-15/DM-25 meets the requirements of the TIA/EIA-136-270-B specification.Pigtail Assembly Right Angle Crimp Jack.152(3.86).223(5.66)0-+0R1>=10kR1>=10kR2R2C1C1C2C2BIASAFMSAGNDInternal App +Internal App -

The module performs a set of telecom servicesaccording to TIA/EIA-136. The functions of the display and keypad, usually used to make calls, are implemented by issuingAT Commands over the serial interface. To find out how to send SMS messages, make data calls, use the burst mode servicesand handle the Phone Book.6.5.1 Speech CallsThe module offers the following telecom services:•Telephony according to EIA/TIA-136.•Emergency according to EIA/TIA-136.An incoming call is indicated by an AT unsolicited result code (RING indicator).The audio input and output signals in the interface (AFMS and ATMS) will carry analog speech in fullduplex (transmitting and receiving simultaneously). The module supports both Full-Rate speech coding andEnhanced Full-Rate (EFR), if EFR is available in the network. For EFR to be usable, changes must be madein the module’s internal parameters.6.5.2 Value Carrier ServicesThe module supports the following value carrier services:•Calling Line Identification Presentation (CLIP). Enables the called module to get the CLI(phone number) of the calling party.•Calling Line Identification Restriction (CLIR). Allows the calling module to enable ordisable the presentation of the CLI (phone number) to the called party when originating a call(dialling).•Call Forwarding. Permits the called module to have the network send incoming calls to adesired phone number.•Call Waiting. Permits the module to be notified of an incoming call, for example, if the moduleis engaged in an active call. The module can either accept, reject or ignore the incoming call.
DM15/25 Integrator’s Manual 32 OF 38•Conference Calls (Multiparty). Permits the module to maintain simultaneous communicationwith more than one party.•Call Barring. Allows the module to bar certain categories of outgoing or incoming calls. Thecategories are determined by one or more barring programs.Note! Some value carrier services as Call Forwarding and Call Waiting may vary depending on your serviceprovider’s network.Value carrier services are activated/deactivated via the ATD command using a specific code. This code might varydepending on the service provider. Consult your service provider for further information.6.5.3 Short Message ServicesThe DM-15/DM-25 module provides the functional capability to create and send text messages across the airinterface. These messages are transported on the air interface via the layer-3 R-DATA message.The key management attribute of a short message is the folder in which it resides. Folders are convenientgroupings of similar messages. For example, common folders are in-box, out-box and hold-box. This pool offolders use a common set of indices (internally controlled) to reference each message location. The incomingmessages are stored in non-volatile memory until deleted by the host application using the AT+CSDMcommand . The module supports the following SMS services in TDMA:•Sending : Mobile-originated (MO) according to EIA/TIA 136-350.•Receiving: Mobile Terminated (MT) according to EIA/TIA 136-350.The maximum length of an SMS message is 201 bytes.6.5.3.1 Services for Short Message ControlThe services provided by the DM-15/DM-25 module for short message control are the followings:• Message formatting – The module formats short messages for transmitting over the air interface.• Message storage – The module stores messages received over the air interface in an in-box; itqueues messages for transmission over the air interfce in an out-box.• Default information element storage – The module stores default information elements for use informatting short messages.• Message reference assigment – The module assigns message reference numbers to new shortmessages that are transmitted over the air interface.• Message index assigment – The module assigns message index numbers to messages receivedover the air interface.• Privacy Management – The module supports privacy criteria.• Message reporting – The module reports incoming messages received over the air interface.

In this case an external modem connected to the analog audiosignals (ATMS, AFMS) is needed.• Microburst/Vburst mode (by Aeris).• The DM-15/DM-25 module supports Aeris Microburst and Vburst protocols. These protocols enableapplications to send either short messages or 1045 byte data-grams to the Aeris data center. The shortmessages in Microburst mode are sent using dialed digits inside a feature request. Feature requests arepages with a ‘*’ character followed by 15 digits. In Microburst/Vburst mode the DM-15/DM-25module does not use either IRDB or WIN4 list.• The Microburst and Vburst service is detected by listening for pages to area code 175 or area code 180respectively.• Application providers that use Aeris Microburst/Vburst protocols must obtain Microburst and Vburstdocumentation from Aeris (see section 1.4)• Sony Ericsson Burst Modem.• The Sony Ericsson Burst Modem protocol enables applications to send 250-byte messages on anAMPS voice channel.• In order to have a complete solution customers must develop an application to control the module,obtain service with a cellular provider, and develop a call center to process incoming data packets orvoice calls.• The DM-15/DM-25 module supports several control channel selection modes. The Sony EricssonBurst Modem protocol may use a standard IRDB lookup mode or a GTE Win4 scanning mode..

Host Modem Server The 250 Byte Message ProtocolThe key feature of the 250-byte protocol is that it allows applications to send up to 250 bytes of dataduring a voice call. The voice conversation is suspended while data is transferred.The 250-byte protocol utilizes powerful error detection and correction algorithms to maximize thechance of delivering error free data. The data in each packet is duplicated three times to enablemajority logic correction, the data is encoded with a convolution encoder that allows multiple biterror correction, and each ten data bytes are protected by a 16 bit CRC. If a first attempt to send thedata packet fails then it is retransmitted up to two more times. The time to send 250 bytes variesbetween 5 and 15.5 seconds depending on the number of retransmissions.6.5.5 Telematics capabilitySony Ericsson DM-15/DM-25 modules can be used in two different modes. The two modes arecalled NAM-1 and NAM-2. In NAM-1 mode the module is a TDMA dual mode phone.Applications can use NAM-1 mode to place analog or digital calls. NAM-1 also supports digitaldata modes such as short message service. In NAM-2 mode, also called “telematics” mode, themodule behaves similar to an AMPS-only phone. Applications can use telematics mode to sendshort data packets on an analog voice channel.In order to switch between NAM-1 and NAM-2 modes the module must be reset, thereforeapplications that desire to use both modes are necessarily more complex. The NAM-1 and NAM-2modes share the same ESN as well as most of the configuration settings. The important exceptionsare MIN, band order, SID and SOC. These parameters can be set independently for telematics
DM15/25 Integrator’s Manual 35 OF 38mode. This means that applications that want to use both modes may choose a different carrier forNAM-2. Using different carriers raises some complications with IRDB settings..6.5.6 Over the air activation (OTA)The DM-15/DM-25 supports Over the Air Programming as defined in EIA/TIA 136 Rev. B6.5.7 Hints for integrating the moduleThis chapter, which gives you advice and helpful hints on how to integrate the DM-15/DM-25 withthe application, should be taken as a guide.Note! The circuits on the test board are not shielded. Thus take proper precautions for avoidingESD and EMI.6.5.8 PrecautionsHere is a list of preparations that you should make before beginning the integration work that isdescribed in this chapter.•Where to install the module.•Safety Standards.•Network and subscription.•Antenna.6.5.9 Where to install the moduleMake sure that the module is installed so that the environmental conditions, such as temperature,humidity, vibration, etc., are not beyond the limits specified for it. See also section 7 TechnicalData.Make sure that the signal strength is sufficient. To improve signal strength, move the antenna toanother position. Signal strength may depend on how close the module is to a radio base station.Degradation in signal strength could be a result of disturbance from another source, for example, anelectronic device nearby.You can verify signal strength by issuing the AT command AT+CSQ.Tip! Before installing the module, use an ordinary mobile telephone to check a possible location forit. Consider signal strength as well as cable length in determining the location for the module andantenna. That way, you will find out if it is practical to install the module where you intended.
DM15/25 Integrator’s Manual 36 OF 386.5.10 Network and subscriptionMake sure that the AMPS/TDMA network provides the necessary telecommunication services.Contact your service provider. Make sure that the location at which you intend to use the module iswithin the network coverage.If you intend to use SMS for the application, make sure that this is included in your (voice)subscription.6.5.10.1 Possible communication disturbances•Noise can be caused by electronic devices and radio transmitters.•Path-loss occurs as the strength of the received signal steadily decreases with the distance fromthe transmitter.•Shadowing is a form of environmental attenuation of radio signals that is caused by hills,buildings, trees or even vehicles. Inside buildings this can cause problems, especially if thewalls are thick and reinforced.•Multi-path fading is a sudden decrease or increase in the signal strength. This is the result ofinterference caused when direct and reflected signals reach the mobile phone simultaneously.Flat surfaces such as buildings, streets, vehicles, etc, can reflect signals.•Hand-over occurs when you move from one cell to another in the AMPS/TDMA network. Ittransfers your present mobile phone call from one cell to another. Hand-over will interferebriefly with communication and could cause a delay, or at worst, a disruption.
