385700-1006-006 INSTALLATION

1.3 DESCRIPTION OF EQUIPMENT

The Radio Communications Network consists of Base and Mobile Radio Communication Systems (RCS). The Base RCS includes Base Data Radios (BDR) connected to wayside Control Equipment. The Mobile RCS includes Mobile Data Radios connected to Control Equipment on board the vehicle. The Radio Communications Systems provide bi-directional communications. 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 are Spread Spectrum non-licensed RF transceivers.

1.3.1 TYPE OF EQUIPMENT

The MDR and BDR are non-licensed spread spectrum transceivers that operate in the ISM 2400-2483.5 MHz frequency band. Antennas connected to MDR and BDR may come from different vendors. Antennas should support the 2400-2483 MHz frequency band, be compliant with FCC part 15 regulations, and are to be inst alled by professional parties.

Refer to Table 1-1 MDR/BDR Types and Applications. The following table contains part numbers for different versions of MDR and BDR.

385700-1006-006 INSTALLATION

1.4.1 MOBILE DATA RADIO ASSEMBLY

The mobile data radio (MDR) uses direct sequence spread spectrum modulat ion techniques. The MDR transmits at a center freq uency of 2467.84 MHz. and receives at a center f r equency of 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-232 interface at J3. An operator can also communicate with the MDR t hrough the diag nostic port across an RS-232 interface (refer to paragraph 2.5. 2) at J4. This int erf ace is r ef err ed to as the Local Command Processor (LCP) terminal and is used to load user supplied paramet ers into the radio’s non-volatile memory when the radio is initially delivered to the customer. This RS232 interface is not used during nor m al oper ation of the radio. The MDR receives power from a nominal 28 VDC (or a nominal 36 VDC depending on application), power source at J1. Refer to Table 1-2 Mobile Data Radio Assembly Specif icat ions.

1.4.2 BASE STATION RADIO ASSEMBLY

The base data radio (BDR), like the MDR, is a spread spectrum transceiver. The BDR transmits at a center fr equency of 2416. 64 MHz frequency and receives at a center f req uency of 2457.84 MHz band. Refer to Table 1-3 Base Stat ion Radio Assembly Specifications. The BDR communicates across an EIA 530 (RS-422) inter face to the wayside control equipm ent at J2 or J3 (see Figure 2-10). An oper ator can also communicate with the BDR through the diagnostic port, J4, across an RS-232 interface (refer to paragraph 2.5.2). This interface is referred to as the Local Command Processor (LCP) ter minal and is used to load user supplied parameters into the radio’s non-volatile memory when the radio is initially delivered to the customer. This RS-232 interf ace is not used during normal operation of the radio. The BDR receives its AC input power at J1. Tables 1-2 through 1- 3 contain the specifications for the MDR and BDR. The tables include characteristics and specifications in three categories: technical, environmental, and physical.

CHAPTER 4

PRINCIPLES OF OPERATION

4.1 FUNCTIONAL DESCRIPTION OF EQUIPMENT

4.1.1 MOBILE DATA RADIO AND BASE DATA RADIO

The BDR and MDR are full duplex transceivers that operate as intentional radiators in the FCC's 2400-2483.5 MHz industrial, scientific, and medical (I SM) band in North America and within 2400-2500 MHz international band. They operate as unlicensed devices and are compliant to the applicable FCC part 15 regu lat ions.

The MDR employs both Code Division Multiple Access (CDMA) and Time Division Multiple Access (TDMA) techniques. CDMA is a function of the Pseudo-random Noise (PN) code selected for transmission and reception. The particular techniq ue used in Andrew Base and Mobile Data Radios is Direct Sequence Spread Spectrum (DSSS) technique. In the direct sequence technique, the information spectrum is spread into a bandwidth many times wider than the bandwidth of the data alone by using a pseudorandom noise seq uence clocked at a rate significantly greater than the information rate. Each data bit is encoded with a pseudorandom spreading code. The receiver can recover the original data by using the same sequence to decode the encoded data bits. Any other selected pseudorandom sequence simply appears as additional noise at the receiver.

When power is applied to a radio, the radio configures the transmit and receiver spreading sequences from data stored in the radio’s nonvolatile memory. Af ter the r adio config uration is completed, the Control Equipment can change the spreading sequences. The base station radios and mobile data radios maintain a pool of available PN codes or channels. Each radio requires a code. The transmit and receive codes are diff erent. T he receive code of the MDR or BDR must equal the other unit’s transmit code. Adjacent BDRs should not have the same codes.

In normal operation, all MDR’s in the same control zone operat e with the same set of t ransmit and receive spreading codes. Time Division Multiple Access techniques are used to minimize interference between the MDR’s.

Normally, the BDR keeps its transm itter on all the time. The MDR on the vehicle turns on it s transmitters in response to being specifically polled by a BDR. The BDR comm ands the MDR to bring up its transmitter and send any pending poll responses from the vehicle control equipment. The MDR turns off it s transm itt er if it f ails to g et conf irm ation in a cert ain period of time that the BDR has “locked” t o the MDR. Also, MDR will turn off its transmit ter after the BDR successfully “locks” to the MDR transmitt er and the MDR sends its response to the BDR.

385700-1006-006 OPERATIONS

4.1.2 RADIO NETWORK ARCHITECTURE

The typical communication flow consists of wayside equipment (user control equipment and BDRs) communicating with mobile equipment (user control equipment and MDRs). W ayside to mobile communication can be distributed over a single or a number of radio net works. Each control region is considered as a single radio network. The regional contr ol equipment uses a simple roll-call polling technique to communicate with all the vehicles in the r egion during a communication cycle. When a train approaches a region boundary it is handed over to the next region's radio network by using a software hand-off algorithm.

4.1.2.1 RF TRANSMISSIONS

Full duplex operation is achieved by utilizing separate frequency ranges within the 2400 -

2483.5 MHz band for each direction of communications. Data is t ransmitted from base radio to

mobile using one range and from mobile to base radio over another frequency rang e. Refer to Table 1-2 Mobile Data Radio Assembly Specifications and Table 1-3 Base Station Radio Assembly Specifications.

4.1.2.2 BASEBAND DATA RATE

The radio network operates at a synchronous baud rate of 64Kbps.

4.1.2.3 OSI LAYERS

The radio network is developed following the ISO (International Standard Org anization) Open Systems Interconnection (OSI) Reference Model. The radio network is modular in design. Industry standard protocol, interfaces and hardware are used to easily interface third party equipment.

4.1.2.3.1 PHYSICAL LAYER

The physical layer is composed of a synchronous serial interface between the control equipment and the base or mobile transceiver and a radio to radio link based on spread spectrum technology. The baseband interf aces are based on the EIA-530 inter face. The RF radio link is based on Direct Sequence Spread Spectr um modulation.

4.1.2.3.2 DATALINK LAYER

The data link layer is based on the HDLC (High-level Data Link Control) protocol to communicate over the radio channel between the base Radio Communication System (RCS) and mobile RCS. The same protocol is also used to comm unicate between the RCS and the control equipment over the EIA-530 interf ace. A sliding window of one is implemented for t he transfer of HDLC I nformation Frames (I frames).

The HDLC Information frame ( I fram e) form at is used to transf er data between the base radio and mobile radio as well as between the radio system and control equipment. T he length of a frame is programmable. Currently is set to 81 bytes (including the two flag bytes). The wayside control equipment sends an ATC frame t o the radio system along with proper RCS address, control byte and CRC. The first two bytes of the ATC f rame will contain the address of the vehicle. This vehicle address will be used by the radio system to address a m obile r adio on a vehicle. The control byte determines the type of frame. The radio communicat ion system adds the CRC and flags to the ATC frame and transmits the packet over radio channel.

A mobile radio is addressed by its two byte Address. Two addresses are reserved. A train address 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 will automatically be retransmitted by the BDR until the regional control equipment clears the frame. A vehicle will send no response to the broadcast messag e.

Document use is restricted to that described on cover 4-4

385700-1006-006 OPERATIONS

The radio communication system at the receiving end receives the pack et and passes it to the vehicle control equipment. The successful receipt of an I frame must be acknowledged by the receiving RCS and control equipment. T his is done by incrementing the Nr f ield of the control byte within the next frame sent.

If a vehicle has more than one radio communications system, one of them acts as the main unit and the others act as auxiliary radios. An MDR responds to a poll only if it is pre-loaded with a response message by the vehicle control equipment. For vehicles with more than one MDR, the vehicle control equipment must direct which MDR will be pre-loaded with a response. Hence, all radio systems in a train receive the message from the region control equipment but only the main radio system sends the response back .

Additional information about the message protocol can be found in the referenced ICD document.

4.1.3 MDR/BDR COMMUNICATIONS HANDLING

A communications cycle is the exchange of information between the wayside control equipment and each vehicle control equipment within the region. During a typical communications cycle, each vehicle control equipment will be sent a poll request , which will be acknowledged by a poll response from the vehicle control equipment . Each communications cycle is followed by the specific command that clears untransmitted messages before proceeding. The wayside control equipment must query the base data radio every 10 to 20 ms for a poll response, and all poll requests must be sent to the base radio at the beginning of the communications cycle (within the constraints of the prot ocol). Mobile radios are polled in sequence one after the other in a round robin fashion.

The data exchange is based on the High-Level Data Link Control (HDLC) standard prot ocol to communicate over the radio channel between the Andrew base and mobile radios. The same protocol is also used to communicate between base radio and wayside control equipment and between mobile radio and mobile control equipment over the EIA-530 interface. The handshaking sequence required by the communications protocol precedes each poll response.

The referenced Interface Control Document est ablishes the protocols and interfaces between wayside and vehicle Control Equipment and Mobile and Base Data Radios.

4.1.4 PN SPREADING CODES

The Direct Sequence Spread Spectrum and CDMA operation of the radios are controlled by the 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 the MDR receive spreading code, (2) that that the MDR transmit spreading code equal the BDR receive spreading code, and (3) that the transmit and receive spreading codes within any radio 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 Communication System Interface Control Docum ent. Selection of the codes f rom t he LCP terminal is covered in Chapter 8.

4.1.5 ANTENNA SWITCHING CONTROLS

The MDR Data 2 Port includes 3 signals, see MDR Data 2 Por t Pin-out s, that can provide 20 ma of drive current. The current based signals, ANT0-ANT2, can be connected to a user supplied external switch that controls a multiple antenna config uration t hat is connect ed to the MDR. The return current path signals, SIGA GND, are tied together inside the radio. The software control of the antenna select lines is defined in the Radio Communication System Interface Control Document.

The MDR Data 2 Port also provides a power and power return path, see MDR Data 2 Port Pin-outs, to the user. The power sig nal, RADIO PWR, is t aken directly from the user supplied input source. The electrical path is made with 22-g auge wire. The user is responsible to insure that (1) the current dr aw is within the limits that this gauge wire can support and (2) that the user supplied DC power source can supply this current load as well as the current load required by the MDR.

DIAGNOSTIC LCP MENU

8.1 DIAGNOSTIC MENU

Initial configuration and t rouble shooting of the radio equipment is accomplished th rough the Diagnostic port of a radio. A WYSE 100 compatible ter minal or a computer running a ter minal emulation program is attached t o the diagnostic port . This ter minal or com puter is referred to as the LCP terminal elsewhere in this manual. The LCP diagnost ics menu for the MDR and BDR are identical except for a few commands. The differences are noted in the following sections. The diagnostics menu includes user available selections as well as reserved commands for testing the radio. The reserved commands are intended for use by factory trained personnel only. Use of these commands by unauthorized personnel will require the user to perform a power reset to t he unit before normal operation can occur. The following sections are based on a typical LCP menu. The user should contact the factory for updates.

The operator selects a particular command by typing t he command number, which appears t o the left of the com mand, followed by pressing the ENTER (↵) key. If the command requires additional parameters, the LCP program will prompt the user for inputs. All inputs are completed using the ENTER (↵) k ey.

8.3 LCP COMMANDS

A description of the commands, t heir applicability to BDR or MDR, and the required response(s) to be entered are given below.

Send Poll Requests BDR

This command causes the BDR to send or stop sending poll requests to an MDR. The poll request is sent to Vehicle Address 1000 approximate rate of one request per second. The LCP displays the current stat e of the polling after this command is ent ered. The polling state togg les between sending and stopping poll requests each time the com mand is entered.

Vehicle Addr. (Train ID) MDR

This command is used to set the 16 bit address of an MDR. Each MDR requires a unique vehicle address. The allowable address range is 0001 address, FFFF

Set PN Index (CDMA Code) BDR and MDR

This command selects the spreading code to be used by the Transmitt er and Receiver PN spreading generators. The user selects the generator(s), Tx, Rx, or Both to be loaded, and an index number which points to a lookup table of PN generator initial conditions. At the completion of this command, the selected PN generator(s) are reset, the new initial conditions are loaded into the PN generator(s), and the radio displays the new generator PN index.

Program Synthesizers BDR and MDR

This command is reserved for future use or internal unit testing .

Reserved BDR and MDR

This command is reserved for future use or internal unit testing .

Reset DSP BDR and MDR

This command is reserved for future use or internal unit testing .

Reset PN BDR and MDR

This command allows the user to start one of the PN sequences in the radio at a known state. The user is prompted for the type of generator reset (continuous, pulsed, or release from continuous) and which generat or, Tx or Rx, to reset..

Reset PN (RX STROBE)

This command performs a pulsed r eset of the Rx PN generator with a double keystroke entry by the user.

SET UPPER THRESHOLD BDR and MDR

The upper threshold value is part of the r adio r eceiver’s confidence test for det er m ining PN code synchronization. The UPPER THRESHOLD must be greater than the LOWER and LOWER LOCK thresholds. The actual values used are set at the f act ory. Large values for the upper threshold require input high signal levels. If the levels are set too high, the radio will not be able to declare PN synchronization. If the levels are set too low, the radio will falsely declare PN synchronization. This will degrade communications throughput by increasing the amount of time to synchronize to the incoming PN code. Using this command results in an internal radio receiver reset condition. This forces a radio receiver to reacquire PN synchronization. T he range of allowable values is 00

to FF16 subject to the above stated requirement s.

UPPER THRES W /O PN RESET BDR and MDR

This command is similar to the Set Upper Threshold com mand except it does not f orce the radio receiver to reacquire PN synchronization aft er the new threshold is loaded.

SET LOWER THRESHOLD BDR and MDR

The lower threshold value is part of the radio receiver’s conf idence t est f or det ermining PN code synchronization. The LOW ER THRESHOLD must be less than the UPPER THRESHOLD but greater t han the LOWER LOCK thresholds. T he actual values used are set at the factory. Large values f or the lower threshold require input high signal levels. If the levels are set too high, the radio will not be able to declare PN synchronization. If the levels are set too low, the radio will falsely declare PN

Document use is restricted to that described on cover 8-4

385700-1006-006 DIAGNOSTIC LCP MENU

synchronization. This will degrade communications throughput by increasing the amount of time to synchronize to the incoming PN code or by preventing PN code synchronization altogether. Using this command results in an internal radio receiver reset condition, which forces a radio receiver resynchronization. The range of allowable values is 00

to FF16 subject to the above stated requirement s.

LOWER THRES W/O PN RESET BDR and MDR

This command is similar to the Set Lower Threshold comm and except it does not force the radio receiver to reacquire PN synchronization aft er the new threshold is loaded.

SET LOWER LOCK THRESHOLD BDR and MDR

The lower threshold value is part of the radio receiver’s conf idence t est f or maintaining PN code synchronization. The LOWER LOCK THRESHOLD must be less than the UPPER THRESHOLD and is normally less than the LOW ER LOCK thresholds. The actual values used are set at the factory. Larg e values for t he lower threshold requir e input high signal levels. If the levels are set too high, the radio will not be able to maintain PN synchronization. If the levels are set t oo low, the radio will f alsely m aintain PN synchronization. This will degrade communications throughput by increasing the amount of time to correct ly synchronize to the incoming PN code or by preventing PN code synchronization altogether. Using this command results in an internal radio receiver reset condition, which forces a radio receiver resynchronization. T he range of allowable values is 00

to FF16 subject to the above stated requirement s.

DISABLE TRANSMITTER BDR and MDR

This command allows the user to manually turn of f the radio transmitter.

ENABLE TRANSMITTER BDR and MDR

This command allows the user to manually turn on the radio transmitter. If t he radio has not been powered down, the output level will be the last loaded value. If the radio is powered down after selecting this command, t he output level will be the last value saved to non volatile memory. The user can check the level with the STATUS REQUEST command. The user can change the output level with the SET dBm OUTPUT LEVEL command.
