385700-1006-006 INSTALLATIONDocument use is restricted to that described on cover 1-21.3 DESCRIPTION OF EQUIPMENTThe Radio Communications Network consists of Base and Mobile Radio CommunicationSystems (RCS). The Base RCS includes Base Data Radios (BDR) connected to waysideControl Equipment. The Mobile RCS includes Mobile Data Radios connected to ControlEquipment on board the vehicle. The Radio Communications Systems provide bi-directionalcommunications. The systems operate in a combined Time Division Multiple Access (TDMA)and Code Division Multiple Access (CDMA) environment.The Mobile Data Radio (MDR) and Base Data Radios (BDR) in the technical manual areSpread Spectrum non-licensed RF transceivers.1.3.1 TYPE OF EQUIPMENTThe MDR and BDR are non-licensed spread spectrum transceivers that operate in the ISM2400-2483.5 MHz frequency band. Antennas connected to MDR and BDR may come fromdifferent vendors. Antennas should support the 2400-2483 MHz frequency band, becompliant with FCC part 15 regulations, and are to be installed by professional parties.Refer to Table 1-1 MDR/BDR Types and Applications. The following table contains partnumbers for different versions of MDR and BDR.Part No. Type Application385700-1000-001 MDR Input Voltage 18-32 VDC385700-1000-002 MDR Input Voltage 21-56 VDC385700-3000-001 BDR Rack Mounted385700-3000-002 BDR Wall Mounted385700-3000-003 BDR Pole MountedTable 1-1 MDR/BDR Types and Applications1.3.2 PURPOSE OF THE EQUIPMENTThe radio provides a bi-directional communication link between the wayside and the vehiclecontrol equipment.

385700-1006-006 INSTALLATIONDocument use is restricted to that described on cover 1-41.4.1 MOBILE DATA RADIO ASSEMBLYThe mobile data radio (MDR) uses direct sequence spread spectrum modulation techniques.The MDR transmits at a center frequency of 2467.84 MHz. and receives at a center frequencyof 2416.64 MHz.The MDR communicates with the vehicle control equipment across an EIA 530 (RS-422)interface at J2. The MDR can also send messages to external equipment via an RS-232interface at J3. An operator can also communicate with the MDR through the diagnostic portacross an RS-232 interface (refer to paragraph 2.5.2) at J4. This interface is referred to as theLocal Command Processor (LCP) terminal and is used to load user supplied parameters intothe radio’s non-volatile memory when the radio is initially delivered to the customer. This RS-232 interface is not used during normal operation of the radio. The MDR receives power froma nominal 28 VDC (or a nominal 36 VDC depending on application), power source at J1.Refer to Table 1-2 Mobile Data Radio Assembly Specifications.1.4.2 BASE STATION RADIO ASSEMBLYThe base data radio (BDR), like the MDR, is a spread spectrum transceiver. The BDRtransmits at a center frequency of 2416.64 MHz frequency and receives at a center frequencyof 2457.84 MHz band. Refer to Table 1-3 Base Station Radio Assembly Specifications. TheBDR communicates across an EIA 530 (RS-422) interface to the wayside control equipmentat J2 or J3 (see Figure 2-10). An operator can also communicate with the BDR through thediagnostic port, J4, across an RS-232 interface (refer to paragraph 2.5.2). This interface isreferred to as the Local Command Processor (LCP) terminal and is used to load user suppliedparameters into the radio’s non-volatile memory when the radio is initially delivered to thecustomer. This RS-232 interface is not used during normal operation of the radio. The BDRreceives its AC input power at J1. Tables 1-2 through 1-3 contain the specifications for theMDR and BDR. The tables include characteristics and specifications in three categories:technical, environmental, and physical.Figure 1-2 Transmitter Block Diagram

385700-1006-006 OPERATIONSDocument use is restricted to that described on cover 4-1CHAPTER 4 PRINCIPLES OF OPERATION4.1 FUNCTIONAL DESCRIPTION OF EQUIPMENT4.1.1 MOBILE DATA RADIO AND BASE DATA RADIOThe BDR and MDR are full duplex transceivers that operate as intentional radiators in theFCC's 2400-2483.5 MHz industrial, scientific, and medical (ISM) band in North America andwithin 2400-2500 MHz international band. They operate as unlicensed devices and arecompliant to the applicable FCC part 15 regulations.The MDR employs both Code Division Multiple Access (CDMA) and Time Division MultipleAccess (TDMA) techniques. CDMA is a function of the Pseudo-random Noise (PN) codeselected for transmission and reception. The particular technique used in Andrew Base andMobile Data Radios is Direct Sequence Spread Spectrum (DSSS) technique. In the directsequence technique, the information spectrum is spread into a bandwidth many times widerthan the bandwidth of the data alone by using a pseudorandom noise sequence clocked at arate significantly greater than the information rate. Each data bit is encoded with apseudorandom spreading code. The receiver can recover the original data by using the samesequence to decode the encoded data bits. Any other selected pseudorandom sequencesimply appears as additional noise at the receiver.When power is applied to a radio, the radio configures the transmit and receiver spreadingsequences from data stored in the radio’s nonvolatile memory. After the radio configuration iscompleted, the Control Equipment can change the spreading sequences. The base stationradios and mobile data radios maintain a pool of available PN codes or channels. Each radiorequires a code. The transmit and receive codes are different. The receive code of the MDRor BDR must equal the other unit’s transmit code. Adjacent BDRs should not have the samecodes.In normal operation, all MDR’s in the same control zone operate with the same set of transmitand receive spreading codes. Time Division Multiple Access techniques are used to minimizeinterference between the MDR’s.Normally, the BDR keeps its transmitter on all the time. The MDR on the vehicle turns on itstransmitters in response to being specifically polled by a BDR. The BDR commands the MDRto bring up its transmitter and send any pending poll responses from the vehicle controlequipment. The MDR turns off its transmitter if it fails to get confirmation in a certain period oftime that the BDR has “locked” to the MDR. Also, MDR will turn off its transmitter after theBDR successfully “locks” to the MDR transmitter and the MDR sends its response to the BDR.

Waysideto mobile communication can be distributed over a single or a number of radio networks. Eachcontrol region is considered as a single radio network. The regional control equipment uses asimple roll-call polling technique to communicate with all the vehicles in the region during acommunication cycle. When a train approaches a region boundary it is handed over to thenext region's radio network by using a software hand-off algorithm.4.1.2.1 RF TRANSMISSIONSFull duplex operation is achieved by utilizing separate frequency ranges within the 2400 -2483.5 MHz band for each direction of communications. Data is transmitted from base radio tomobile using one range and from mobile to base radio over another frequency range. Referto Table 1-2 Mobile Data Radio Assembly Specifications and Table 1-3 Base Station RadioAssembly Specifications.4.1.2.2 BASEBAND DATA RATEThe radio network operates at a synchronous baud rate of 64Kbps.4.1.2.3 OSI LAYERSThe radio network is developed following the ISO (International Standard Organization) OpenSystems Interconnection (OSI) Reference Model. The radio network is modular in design.Industry standard protocol, interfaces and hardware are used to easily interface third partyequipment.Figure 4-1 Radio Network OSI Layers

385700-1006-006 OPERATIONSDocument use is restricted to that described on cover 4-44.1.2.3.1 PHYSICAL LAYERThe physical layer is composed of a synchronous serial interface between the controlequipment and the base or mobile transceiver and a radio to radio link based on spreadspectrum technology. The baseband interfaces are based on the EIA-530 interface. The RFradio link is based on Direct Sequence Spread Spectrum modulation.4.1.2.3.2 DATALINK LAYERThe data link layer is based on the HDLC (High-level Data Link Control) protocol tocommunicate over the radio channel between the base Radio Communication System (RCS)and mobile RCS. The same protocol is also used to communicate between the RCS and thecontrol equipment over the EIA-530 interface. A sliding window of one is implemented for thetransfer of HDLC Information Frames (I frames).The HDLC Information frame (I frame) format is used to transfer data between the base radioand mobile radio as well as between the radio system and control equipment. The length of aframe is programmable. Currently is set to 81 bytes (including the two flag bytes). Thewayside control equipment sends an ATC frame to the radio system along with proper RCSaddress, control byte and CRC. The first two bytes of the ATC frame will contain the addressof the vehicle. This vehicle address will be used by the radio system to address a mobile radioon a vehicle. The control byte determines the type of frame. The radio communication systemadds the CRC and flags to the ATC frame and transmits the packet over radio channel.Figure 4-3 SCP to RCS Frame FormatA mobile radio is addressed by its two byte Address. Two addresses are reserved. A trainaddress of zero hexadecimal ‘0000’ is not a legal value. The train address hexadecimal ‘FFFF’is reserved for a broadcast message to all the trains in a region. A broadcast message willautomatically be retransmitted by the BDR until the regional control equipment clears theframe. A vehicle will send no response to the broadcast message.Flag RCSAddress ControlByteCommunications-Control System FrameMaximum 75 bytesCyclicRedundancyCheck FlagTrain ID Car ID Region ID ControlByte Communications-Control System DataMaximum 73 BytesATC Equipment to Andrew Radio Frame FormatCommunications-Control System Frame Format
385700-1006-006 OPERATIONSDocument use is restricted to that described on cover 4-5The radio communication system at the receiving end receives the packet and passes it to thevehicle control equipment. The successful receipt of an I frame must be acknowledged by thereceiving RCS and control equipment. This is done by incrementing the Nr field of the controlbyte within the next frame sent.If a vehicle has more than one radio communications system, one of them acts as the mainunit and the others act as auxiliary radios. An MDR responds to a poll only if it is pre-loadedwith a response message by the vehicle control equipment. For vehicles with more than oneMDR, the vehicle control equipment must direct which MDR will be pre-loaded with aresponse. Hence, all radio systems in a train receive the message from the region controlequipment but only the main radio system sends the response back.Additional information about the message protocol can be found in the referenced ICDdocument.4.1.3 MDR/BDR COMMUNICATIONS HANDLINGA communications cycle is the exchange of information between the wayside controlequipment and each vehicle control equipment within the region. During a typicalcommunications cycle, each vehicle control equipment will be sent a poll request, which will beacknowledged by a poll response from the vehicle control equipment. Each communicationscycle is followed by the specific command that clears untransmitted messages beforeproceeding. The wayside control equipment must query the base data radio every 10 to 20ms for a poll response, and all poll requests must be sent to the base radio at the beginning ofthe communications cycle (within the constraints of the protocol). Mobile radios are polled insequence one after the other in a round robin fashion.The data exchange is based on the High-Level Data Link Control (HDLC) standard protocol tocommunicate over the radio channel between the Andrew base and mobile radios. The sameprotocol is also used to communicate between base radio and wayside control equipment andbetween mobile radio and mobile control equipment over the EIA-530 interface. Thehandshaking sequence required by the communications protocol precedes each pollresponse.The referenced Interface Control Document establishes the protocols and interfaces betweenwayside and vehicle Control Equipment and Mobile and Base Data Radios.4.1.4 PN SPREADING CODESThe Direct Sequence Spread Spectrum and CDMA operation of the radios are controlled bythe Pseudo Noise spreading codes contained within the non volatile memory of the radios.Normal operation of the radios requires (1) that the BDR transmit spreading code equal theMDR receive spreading code, (2) that that the MDR transmit spreading code equal the BDRreceive spreading code, and (3) that the transmit and receive spreading codes within anyradio be different. The radios are configured with over 80 different spreading codes.Selection of the codes by the user-supplied equipment is covered in the Radio CommunicationSystem Interface Control Document. Selection of the codes from the LCP terminal is coveredin Chapter 8.

385700-1006-006 DIAGNOSTIC LCP MENUDocument use is restricted to that described on cover 8-1CHAPTER 8 DIAGNOSTIC LCP MENU8.1 DIAGNOSTIC MENUInitial configuration and trouble shooting of the radio equipment is accomplished through theDiagnostic port of a radio. A WYSE 100 compatible terminal or a computer running a terminalemulation program is attached to the diagnostic port. This terminal or computer is referred toas the LCP terminal elsewhere in this manual. The LCP diagnostics menu for the MDR andBDR are identical except for a few commands. The differences are noted in the followingsections. The diagnostics menu includes user available selections as well as reservedcommands for testing the radio. The reserved commands are intended for use by factorytrained personnel only. Use of these commands by unauthorized personnel will require theuser to perform a power reset to the unit before normal operation can occur. The followingsections are based on a typical LCP menu. The user should contact the factory for updates.The operator selects a particular command by typing the command number, which appears tothe left of the command, followed by pressing the ENTER (↵) key. If the command requiresadditional parameters, the LCP program will prompt the user for inputs. All inputs arecompleted using the ENTER (↵) key.

Thepoll request is sent to Vehicle Address 100016. The poll requests are sent at anapproximate rate of one request per second. The LCP displays the current state of thepolling after this command is entered. The polling state toggles between sending andstopping poll requests each time the command is entered.Vehicle Addr. (Train ID) MDRThis command is used to set the 16 bit address of an MDR. Each MDR requires aunique vehicle address. The allowable address range is 000116 to FFFE16 . Theaddress, FFFF16, is reserved for the Broadcast message.
385700-1006-006 DIAGNOSTIC LCP MENUDocument use is restricted to that described on cover 8-4Set PN Index (CDMA Code) BDR and MDRThis command selects the spreading code to be used by the Transmitter and ReceiverPN spreading generators. The user selects the generator(s), Tx, Rx, or Both to beloaded, and an index number which points to a lookup table of PN generator initialconditions. At the completion of this command, the selected PN generator(s) arereset, the new initial conditions are loaded into the PN generator(s), and the radiodisplays the new generator PN index.Program Synthesizers BDR and MDRThis command is reserved for future use or internal unit testing.Reserved BDR and MDRThis command is reserved for future use or internal unit testing.Reset DSP BDR and MDRThis command is reserved for future use or internal unit testing.Reset PN BDR and MDRThis command allows the user to start one of the PN sequences in the radio at aknown state. The user is prompted for the type of generator reset (continuous, pulsed,or release from continuous) and which generator, Tx or Rx, to reset..Reset PN (RX STROBE)This command performs a pulsed reset of the Rx PN generator with a doublekeystroke entry by the user.SET UPPER THRESHOLD BDR and MDRThe upper threshold value is part of the radio receiver’s confidence test for determiningPN code synchronization. The UPPER THRESHOLD must be greater than theLOWER and LOWER LOCK thresholds. The actual values used are set at the factory.Large values for the upper threshold require input high signal levels. If the levels areset too high, the radio will not be able to declare PN synchronization. If the levels areset too low, the radio will falsely declare PN synchronization. This will degradecommunications throughput by increasing the amount of time to synchronize to theincoming PN code. Using this command results in an internal radio receiver resetcondition. This forces a radio receiver to reacquire PN synchronization. The range ofallowable values is 0016 to FF16 subject to the above stated requirements.UPPER THRES W/O PN RESET BDR and MDRThis command is similar to the Set Upper Threshold command except it does not forcethe radio receiver to reacquire PN synchronization after the new threshold is loaded.SET LOWER THRESHOLD BDR and MDRThe lower threshold value is part of the radio receiver’s confidence test for determiningPN code synchronization. The LOWER THRESHOLD must be less than the UPPERTHRESHOLD but greater than the LOWER LOCK thresholds. The actual values usedare set at the factory. Large values for the lower threshold require input high signallevels. If the levels are set too high, the radio will not be able to declare PNsynchronization. If the levels are set too low, the radio will falsely declare PN
385700-1006-006 DIAGNOSTIC LCP MENUDocument use is restricted to that described on cover 8-5synchronization. This will degrade communications throughput by increasing theamount of time to synchronize to the incoming PN code or by preventing PN codesynchronization altogether. Using this command results in an internal radio receiverreset condition, which forces a radio receiver resynchronization. The range ofallowable values is 0016 to FF16 subject to the above stated requirements.LOWER THRES W/O PN RESET BDR and MDRThis command is similar to the Set Lower Threshold command except it does not forcethe radio receiver to reacquire PN synchronization after the new threshold is loaded.SET LOWER LOCK THRESHOLD BDR and MDRThe lower threshold value is part of the radio receiver’s confidence test for maintainingPN code synchronization. The LOWER LOCK THRESHOLD must be less than theUPPER THRESHOLD and is normally less than the LOWER LOCK thresholds. Theactual values used are set at the factory. Large values for the lower threshold requireinput high signal levels. If the levels are set too high, the radio will not be able tomaintain PN synchronization. If the levels are set too low, the radio will falsely maintainPN synchronization. This will degrade communications throughput by increasing theamount of time to correctly synchronize to the incoming PN code or by preventing PNcode synchronization altogether. Using this command results in an internal radioreceiver reset condition, which forces a radio receiver resynchronization. The range ofallowable values is 0016 to FF16 subject to the above stated requirements.DISABLE TRANSMITTER BDR and MDRThis command allows the user to manually turn off the radio transmitter.ENABLE TRANSMITTER BDR and MDRThis command allows the user to manually turn on the radio transmitter. If the radiohas not been powered down, the output level will be the last loaded value. If the radiois powered down after selecting this command, the output level will be the last valuesaved to non volatile memory. The user can check the level with the STATUSREQUEST command. The user can change the output level with the SET dBmOUTPUT LEVEL command.LOAD SC REGISTER BDR and MDRThis command is reserved for future use or internal unit testing.DISABLE TEST PORT BDR and MDRThis command is reserved for future use or internal unit testing.PN TEST SELECT BDR and MDRThis command is reserved for future use or internal unit testing.A/D SELECT BDR and MDRThis command is reserved for future use or internal unit testing.SET CLOCK SEARCH BDR and MDRThis command is reserved for future use or internal unit testing.

The ESCAPE key isused to return the radio to its normal operating condition from this state.SET RCS ADDRESS BDRThis command sets the BDR address. It is used in multiple BDR configurations. Theallowable range of address is 0116 to FE16. A default address of 4016 is preloaded intothe BDR upon power up initialization. See the ICD for further information.SSR STATUS REQUEST BDR and MDRThis command reads the current configuration data stored inside various moduleswithin the radio. It includes a display that indicates whether the data agrees with thedata originally written to the modules. The parameters currently supported are thelower lock, lower, and upper thresholds, the Tx and Rx PN code, the Tx and Rx DataRates, and the current state of the Transmitter. All other parameters are for futureuse.STATUS REQUEST BDR and MDRThis command displays the current radio configuration as stored in the radio’s volatilememory. The parameters currently supported are the lower lock, lower, and upperthresholds, the Tx and Rx PN code, the Tx and Rx Data Rates, and the current stateof the Transmitter. All other parameters are for future use.SHOW POLL COUNTERS BDRThis command displays a group of communication counters that monitor the pollingactivity between the BDR and MDR and special flags used for internal radio codedebugging. The counter types currently supported are the number of poll requestsinput to the BDR, the number of frames transmitted from the BDR controller to theradio RF transmitter, the number of valid poll responses received from the MDR, thetotal number of frames received from the radio RF port at the BDR controller, and thenumber of poll request retransmission attempts.CLEAR POLL COUNTERSThis command zeroes a group of communication counters that monitor the pollingactivity between the BDR and MDR.READ TRACK/AGC VALUES BDR and MDRThis command is reserved for future use or internal unit testing.SET dBM OUTPUT LEVEL BDR and MDRThis command is used to set the transmitter output power level of the radio. Therange of listed output levels may be greater than the specifications of the radio. Whenusing this command, the user must set the output level such that compliance with FCCoutput level requirements are maintained. The output resolution is in 1 dB increments.CHANGE dBM/DAC VALUES BDR and MDRThis command is reserved for factory calibration or internal unit testing. Thecommand, Set dBM Output Level, is used to enter the PA control voltagescorresponding to an RF output levels. After entering the voltage/ RF levels, the user
