Channell through 15, and $0 Channell).

1.2 DMP 4O-CONDUCTOR INTERFACE CABLE

The DMP comes with a separate 40-conductor ribbon in-

terface cable, a separate 8-conductor metering cable with

"modular" connectors, two separate voltage probes and

a set of housing rods that may be extended and inserted

into the mounting rails inside the station cabinet. Refer

to Figure 2 for the locations of the connectors used for

the CONTROL (11201), METER (11202), +voltage

probe (11203), and - voltage probe (11204). Refer to

Figure 3 for a view of the DMP with its front panel re-

moved.

The 40-conductor interface cable connects the station

EXPANSION connector J800 (located on the top of the

control tray housing) to the DMP CONTROL connector

J1201. This cable provides interface lines which connect

power, audio and digital signals between the station con-

trol board, other control modules within the station, and

the DMP. There are four types of signal lines provided,

as follows:

•• audio line

., dedicated logic line

., multiplexed logic (MUXbus) lines

., power and ground lines

268P81114E03

SELECT AUDIO Pin 32) - Audio line

The Select Audio signal, originating on the station control

module, is the audio input for the local speaker amplifier

circuit in the DMP. Any of the following audio signals will

be present on the select audio line when it is properly

gated by the control circuits in the station: primary receiv-

er audio, secondary receiver audio, transmit audio from

the remote wire line, and automatic station LD. and

alarm tone audio. The Select.Andio line is connected to

the wiper of the VOLUMpcontrol on the control tray

front panel. Therefore, the debias level and ac level on

the line varydepending onthe VOLUME control setting.

The DMP employs an audio power amplifier circuit to

provide up to 5watts of local service audio from the Select

Audio signal, through the DMP internal 4-ohm speaker.

The audio power amplifier circuit can be disabled with

SPEAKER ON/OFF switch S121O,located on the face of

the DMP. By connecting an optional microphone

(HMN1001) to CONTROL Jack J812 on the front panel

of the station control tray, the transmitter can be locally

keyed and modulated, or intercom with the remote con-

trol.console operator can be accomplished.

e.EXPANSION RESET signal is a shared logic line

whiChallows a clean, coordinated start up of the station

co:fltro1module and any other interconnected modules or

e t rnal equipment (such as the DMP). The EXPAN-

QN RESET signal is active low at power-up, or when

station control module switch S801 is put into the TEST

position, or when t station control module is reset by

its watchdog timer circuit, or when another control mod-

ule receives a command to reset the station. Also, normal

MUXbus operation is suspended while the watchdog tim-

er circuit generated RESET signal is active low. The

MUXbus data strobe line DS, is held inactive and the

MUXbus address and data lines do not follow their nor-

mal patterns.

IMPORTANT

While the EXPANSION RESET line is

active low, no module except the station

control module should write to the MUX-

bus data lines. Otherwise, the station con-

trol module may fail its self diagnostic

tests, and remain reset indefinitely.

Multiplexed Logic MUXbus) lines

The multiplexed logic (MUXbus) lines consist of the fol-

lowing signals:

Four Address lines (BAO-BA3) - Pins 13-16

•• Four Data lines (BDO-BD3) - Pins 17-20

•• Data strobe (DS) - Pin 22

All DMP MUXbus lines are referenced to audio ground

data lines define 16 words of 4 bits each, or 64 total bits

as shown in Table 1. These bits form a multi-directional

digital communications path. The bus is multiplexed to

conserve interconnections (64 connections reduced to 9)

and to increase future expansion capability. The data

strobe and the four address lines are driven by the

control module. The data lines are.inverted and open col-

lector driven in both the station control module and the

DMP. This allows the station control module and the

DMP to drive the same bit in a nondestructive, wired

"OR" fashion.

The MUXbus timing diagram is shown in Figure 4. The

address lines are incremented once, approximately every

1.3 DMP 8-CONDUCTOR METERING CABLE

The 8-conductor metering cable connects the DMP ME-

TER Jack J1202 to either the station TX Metering or sta-

tion RX Metering Jack. The TX and RX Metering Jacks

(J413 and J21O, respectively) are both located on the sta-

tion RF Tray front panel. The PAMetering Jack (J503) is

located on the PA Distribution Board, within the station

Power Amplifier Deck. This cable provides interface lines

which connect five metering lines and a meter common

line to the DMP, as shown in Table 2.

1.4 VOLTAGE PROBES

The two voltage probes plug into two jacks provided on

the bottom edge of the DMP: RED =

"+"

=J1203;

BLK

= "-" =

J1204. Each of the probes is equipped

with a reversible blunt or pointed tip.

2. METERING FACILITIES

The DMP provides a measured indication for the signals

listed in Table 2 on a 0-50

J.l.A

full-scale meter (MI201).

The proper indications are the same as those obtained us-

ing a Motorola Portable Test Set or TEK-5F Meter Panel,

as described in the MSF5000 Base Station and Repeater

Instruction Manual. A specific meter position is selected

by using the METER selector switch S1208 on the face of

the DMP. When METER selector switch S1208 is in the

"10 V" or "25 V" position, the meter monitors the volt-

age probes and is calibrated to read full-scale voltage (in-

stead of full-scale microamperes).

IMPORTA.NT

When measuringthe.power amplifier cir-

cuits, via J503, meter REVERSING switch

S1209 must be placed in the "-" (or re-

verse) position. METER REVERSING

switch S1209 is normally in the"

(or

forward) position when the DMP is con-

nected to either J413 or J210 (TX or RX

Metering, respectively).

3. DIAGNOSTIC FACILITIES

3.1 GENERAL

The right hand portion of the DMP contains the switches

and displays required to monitor and manipulate the op-

erating parameters of the station. These functions are

made possible by connecting circuits of the DMP to the

MUXbus of the station EXPANSION connector (J800).

3.2 CHANNEL DISPLAY

The CHANNEL display consists of two 7-segment LED

packages that are used to display the station's current aux-

iliary operating channel (left-most unit) and its current

primary operating channel (right-most unit). The primary

operating channel is the channel currently selected for

the station transmitter and primary receiver. The auxilia-

channel may have several uses, one of which is that it

would be the selected channel of the secondary receiver

in a 2-receiver station. The operating CHANNEL display

changes each time the station changes operating channel,

or the operating channel is changed via the channel select

switch on the station control tray. The auxiliary CHAN-

NEL display changes only when a change of operating

channel occurs.

3.3 STATUS DISPLAY

The Station Parameter Status Display Matrix consists of

eight 8 element LED packages located behind the re-

cessed sceened panel of the DMP. The screening identi-

fies each of 641vlUXbus bits, via a specific mnemonic des-

ignation, as shown in Thole 1.

The STATUS DisplaY.Pl ()vides a visible indication of the

major portion of the main control related activities that

are occurring at any timejn. the station. These include var-

ious push-to-talk signals, the state of the squelch circuits,

the presence of properly coded squelch signals, the sta-

tion channel, the station-level alarms and wild card

functions, as well as specialized activities such as Chan-

nel-Scan or DVP operation.

NOTE

To check to see if all the LEDs in this sec-

tion of DMP are functional, momentarily

switch the ENIER DATA-TEST switch to

the TEST position. AU 64 LEDs in the

STATUS display area should light, and the

two-digit CHANNEL display should indi-

cate $FF.

The STATUS Display indicates the active control condi-

tions within the station with a corresponding illuminated

LED. The absence of an expected condition can be readily

observed as the station is operated, leading to rapid iden-

tification of a defective area.

To simulate an active condition in the station using the

DMP, select the address or row in the display containing

the particular signal with the ADDRESS switch. Next, set

one of the data switches DO through D3 corresponding to

the column in the display containing the signal. Momen-

tarily switch the ENTER DATA-TEST switch to the EN-

TER DATA position and the condition will become ac-

tive. To clear the condition, return the data switch to the

OFF position and flip the switch to the ENTER DATA

position once again.

CAUTION

It is recommended that the DMP be dis-

connected from the control tray (via J8oo)

during station power up. This prevents the

station from being initially activated in a

possible undesirable function. However, if

the station is powered up with the DMP

connected, and an undesirable condition

does occur, place the four DATA switches

to the OFF position, and then toggle the

ENTER DATA switch. This will deactivate

the four DMP data bits applied to the

MUXbus Data Line and remove the unde-

sirable condition

7/15/90 68P81114E03

DI GNOSrrIC MErrE ING P NEL.;

An active condition is also cleared when the ADDRESS

switch is moved to a different address, and the ENTER

DATA switch is used to activate a MUXbus bit at the new

address.

For example, suppose it is desired to verify that the proper

alarm tones would be sent by the station in the event of

a PA failure. To simulate this alarm condition using the

DMP, set the ADDRESS switch to 12 (the row containing

the PA alarm signal) and flip the data switch up (for the

column containing this signal (D1). Flip the ENfER

DATA switch, illuminating the LED in the status display

for PA alarm and activating a simulated PA failure alarm.

If the station is working properly, two beeps will be heard.

If the Dl switch is turned to the OFF position and the EN-

TER DATA switch is activated, the PA alarm LED will

tum off, and the alarm beeps will cease. Likewise, if the

ADDRESS switch is moved to address 1, and the D1

switch is left in the up position, then when the ENTER

DATA switch is activated, the PA alarm LED will turn off,

the alarm beeps will cease, the LOCal PTf LED will illu-

minate, and the station will key up.

NOTE

Status only bits, when activated by the

DMP, will cause their corresponding LED

to light, but will not affect a change in sta-

tion operation. The station causes these

LEDs to light when it has successfully ac-

complished a certain function.

4. MUXBUS BIT DEFINITIONS

4.1 INTRODUCTION

The following paragraphs provide definitions for each of

the 64 operating parameters (MUXbus Bits) displayed by

the DMP. Each of these bits may have their state changed

by the DMP. Each paragraph title gives the MUXbus Bit

mnemonic, definition, and row-column address required

for access (in the form: #, D#), respectively.

4.2 SP XMIT (SPECIAL TRANSMIT) 0, D3

The SP XMIT bit indicates that the deviation and/or the

rf PA power should be either boosted or cut, defined by

information in the station control module code plug. The

default condition in the station control module code plug,

upon activation of this MUXbus bit, is deviation control.

This bit will only have an effect during a PIT. The activa-

tion of this bit, by itself, will not key the station.

4.3 SCAN (SCAN ENABLE) 0, D2

The SCAN bit forces the station control module to enable

the primary receiver as a scanning receiver. The station

must be ordered with the Channel-Scan option in order

for this feature to operate. Only the primary receiver can

scan.

4.4 T ALM DS (TOTAL ALARM DISABLE) 0, Dl

The T ALM DS bit mutes all alarm tones until this bit is

deactivated. This bit will deactivate the station control

module alarm bits on the Reverse Wild Card bits 1

through 4, but will not affect the other Reverse Wild

Card bits on the MUXbus. Pulsing T ALM DS for 25

msec or longer will release S ALM DS, if active.

4.5 S ALM DS (SELECTIVE ALARM DISABLE) O,DO

The S ALM DS bit is meant to support a nuisance avoid-

ance alarm feature. The console operator can mute in-

progress alarm tones without fear of missing any new

alarms. For example, initially all alarm bits (Reverse

Wild Card bits, addresses 12 & 13) and S ALM DS are

inactive. An alarm condition activates an alarm bit, and

alarm tones are heard. The wireline control pulses

S ALM DS active for 25 msec or longer in response to a

remote control console command, and the alarm tones

are muted. If the alarm condition were to disappear, the

corresponding alarm bit would be deactivated, S ALM DS

would be cleared, and no alarm tones would be heard

since no alarm bit is active. If, instead, a second alarm bit

were activated while the first alarm was active, S ALM DS

would be deactivated and alarm tones for both alarms

would be heard. The wireline control could re-enable

S ALM DS, then alarm tones for both alarms would be

muted. S ALM DS does not deactivate the MUXbus

alarm bits, but merely mutes the alarm tones.

4.6 RPT PTT (REPEATER PUSH-TO-TALK) 1, D3

The RPT PTT bit keys the transmitter, modulating with

RX 1 Audio if no higher-priority PTT is active. If a high-

er-priority PTT is active, the station control module deac-

tivates RPT P1T. If the repeater PTT time-out timer

(TOT) times out, RPT PTT will be deactivated, and the

transmitter will dekey. If repeater knock down (RPT KD)

goes active while RPT PTT is active, RPT PTT will be

deactivated, PL reverse burst or DPL turn off code

RBI

TOC) will be encoded if appropriate, and the transmitter

will dekey. RPT PTT is active during repeater drop-out

delay. RPT PTT is inactive when RBITOC is encoded.

The station control module turns on RPT P1T, if repeater

audio activity exists on Receiver 1, and if RPT KD is inac-

tive, and if no higher-priority PTT is active. Repeater

audio activity is set for each channel by station control

module code plug qualifiers. These qualifiers determine

what combination of the four MUXbus bits RX P L DS,

Rl PL DT, RPT USQ, and AUX DET are ANDed to ob-

tain RPT

PTf.

Line, Local, and Repeater PTT priorities

are set for each channel by station control module code

plug qualifiers.

4.7 LIN PTT (LINE PUSH-TO-TALK) I,D2

The LIN PTT bit keys the transmitter, modulating with

TX Audio (inbound wireline) if no higher-priority PTT is

668P81114E03

active. LIN PTT stays active if a higher-priority PTT is ac-

tive. LIN PTT is inactive when R ITOC is encoded, un-

less the RBITOC is caused by the Line PT T TOT timing

out. If the station is so equipped, LIN PTT switches the

antenna switch to its transmit state. Line, Local, and Re-

peater PTT priorities are set for each channel by station

control module code plug qualifiers

4.8 LOC PTT (LOCAL PVSH- TO-TALK) 1, Dl

The LOC PTT bit keys the transmitter, modulating with

Local Audio if no higher priority PTT is active. LOC PTT

says active if a higher priority PTT is active. LOC PTT is

inactive when RBITOC is encoded, unless the RBIT OC

is caused by the Local PTT TOT timing out. If the station

is so equipped, LO C PTT switches the antenna switch to

its transmit state. LOC PTT is active if the PTT switch is

depressed on the local microphone plugged into the sta-

tion control module front panel CONTROL connector

J812. Line, Local, and Repeater PTT priorities are set for

each channel by station control module code plug qualifi-

ers. The front panel XMIT switch on the station control

module will activate TX PL DS and key the station with-

out activating the LOC PTT bit on the MUXbus. This key

will be without PL, DPL, or audio (silent carrier). As

thusly defined,

is not a true P1T, and can be overridden

by any other PTT

4.9 INTCOM (INTERCOM) 1, DO

The INTCOM bit is active if the remote control module

INTERCOM switch is actuated. When INTCOM is ac-

tive, the station control module treats LOC PTT as an In-

tercom P1T. Local Audio is gated to the wireline (out-

bound wireline) when a local PTT is generated, but the

transmitter is not keyed. When LOC PTT is not active,

remote control console audio (inbound wireline) is gated

to the 112-watt local audio amplifier.

4.10 TX PL DS (TRANSMIT PLIDPL DISABLE) 2, D3

The TX PL DS bit mutes encoded PL or DPL. The Trans-

mit PL Strip wireline option utilizes this bit. If PL or DPL

is being encoded when TX PL DS goes active, then

RBI

TOC will be generated before muting PL or DPL. This

bit will also be set active whenever PLI DPL encoding is

disabled, such as during an auto ID transmission, or if the

front panel XMIT switch on station control module is ac-

tivated.

4.11 TX ACT (TRANSMITTER ACTMTY) 2, D2

The TX ACT is a status only bit, and indicates that the

transmit rf channel (outbound) is ready. TX ACT goes ac-

tive after a keyup, when the transmitter power output has

stabilized. In the event of a PA failure on keyup, TX ACT

stays inactive (doesn't glitch). TX ACT goes inactive

when the station control module dekeys the PA. TX ACT

is inactive during RBITOC.

4.12 RX2 ACT (RECEIVER 2 ACTMTY) 2,

The RX2 ACT bit indicates whether second receiver au-

dio should be used. The second receiver control module

7/15/90

responds to an active RX2 ACT by gating deemphasized,

PL-stripped audio from the second receiver to the RX2

audio line. From there, it is mixed with line audio (out-

bound wireline) by the station control module. RX2 Au-

dio is also mixed with select audio (local speaker) by the

station control module.

4.13 RX1 ACT (RECEIVER 1 ACTMTY) 2, DO

The RXI ACT bit indicates whether the primary receiver

has audio present with the proper qualifiers to unmute re-

ceiver audio. This condition is set for each channel by four

qualifiers in the station control module code plug. These

qualifiers determine what combination of the four MUX-

bus bits RX PL DS, Rl PL DT, Rl UN SQ, and AUX DET

are ANDed to obtain RXI ACf. The station control mod-

ule responds to an active RXI ACT by opening the RXI

audio gate. This gates RXI audio to both the line audio

(outbound wireline) and select audio (local speaker) lines.

RXI audio is also gated to the station control module re-

peater audio gate. If the station is transmitting due to a

RPT PTT, then the repeater audio gate will be open and

RXI audio will be gated, via the IDC circuit, to the TX

modulation audio line.

4.14 RX PL DS (RECEIVE PLIDPL DISABLE) 3, D3

The RX PL DS bit causes the station to revert to carrier

squelch only operation for purposes of determining status

of RXI ACT and RX2 ACf. The Monitor and Receiver

Squelch OnlOff wireline functions utilize RX PL DS.

Also, the station control module front panel PL Disable

switch activates RX PL DS.

4.15 Rl PL DT (RECEIVER 1 PLlDPL DETECT) 3, D2

The Rl PL DT bit is active when PL or DPL coded

squelch is being detected via Receiver 1.

4.16 Rl SQ LV (RECEIVER 1 SQUELCH LEVEL) 3,

The R

SQ LV bit changes the carrier squelch threshold.

When Rl SQ LV is active, the primary receiver is operat-

ing with loose squelch.

4.17 Rl UN SQ (RECEIVER 1 UNSQUELCH) 3, DO

The Rl UN SQ bit is a status only bit, and is active when

the Receiver

audio carrier squelch circuit on the station

control module detects activity. Rl UN SQ is used for au-

dio gating (refer to RX

ACT), not for repeater keying

(refer to RPT

PIT).

4.18 R2 MUTE (RECEIVER 2 MUTE) 4, D3

The R2 MUfE bit causes the second receiver control

module to attenuate the audio driving the RX2 audio line,

so that Local or RXI audio can be heard on both the line

7/15/90 68P81114E03

audio (outbound wireline) and select audio (local speak-

er) lines. The attenuation is accomplished by means of a

potentiometer on the second receiver control module.

Therefore, RX2 audio can be fully muted, if desired.

4.19 R2 PL DT (RECEIVER 2 PLlDPL DETECT) 4, D2

The R2 PL DT is active when PL or DPL coded squelch

is being detected via Receiver 2.

4.20 R2 SQ LV (RECEIVER 2 SQUELCH LEVEL) 4, D1

The R2 SQ LV bit changes the carrier squelch threshold.

When R2 SQ LV is active, the second receiver is operat-

ing with loose squelch.

4.21 R2 UN SQ (RECEIVER 2 UNSQUELCH) 4, DO

The R2 UN SQ bit is a status only bit, and is active when

the Receiver 2 audio carrier squelch circuit on the second

receiver control module detects activity. R2 UN SQ is

used for audio gating (refer to RX2 ACT). The second re-

ceiver can neither key the repeater (activate RPT

PIT),

nor modulate the transmitter.

4.22 GD TN DT (GUARD TONE DETECT) 5, D3

The GD TN DT bit becomes active whenever high level

guard tone is detected from the TX Audio signal (inbound

wireline) by the tone remote control module. In stations

with an antenna switch, the station control module re-

sponds to an active GD TN DT by switching the antenna

switch to its transmit state. The TX Audio signal is muted

(on the station control module) while GD TN DT is ac-

tive, in order to prevent remote control tones from being

transmitted.

4.23 AUX DET (AUXILIARY DETECT) 5, D2

The AUX DET bit indicates that an optional decoder is

detecting. The optional decoder may be connected to ei-

ther Receiver

or Receiver 2 audio. AUX DET can be

used to activate TXl ACT , RX2 ACT, and RPT

PIT

a manner similar to the Rl PL DT and Rl UN SQ qualifi-

ers.

4.24 RPT KD (REPEATER KNOCK-DOWN) 5, Dl

The RPT KD bit disallows a repeater PTT. Also, this bit

forces an existing active RPT

PIT

inactive.

4.25 RPT USQ (REPEATER UN SQUELCH) 5, DO

The RPT USQ bit is a status only bit, and

active when

the Receiver

repeater carrier squelch circuit, located on

the station control module, detects activity. This bit

used to key the repeater, not to gate audio (refer to RPT

PTT).

4.26 ACC DIS (ACCESS DISABLE) 6, D3

The ACC DIS bit is a status only bit, and is active when

the Access Disable station control module switch is actu-

ated. ACC DIS active indicates that the following five

functions are inhibited: 1) Auto ID; 2) Alarm tones; 3)

Time-out timers;

Repeater

PIT

initiated from the pri-

mary receiver; and, 5) Wire line commands including Line

P1T. When Access Disabled, the station operating chan-

nel is selected with the CHANNEL select switch, located

on the front panel of the remote control module. The pre-

vious station operating channel is remembered by the

station control module and reinstated when the Access

Disable switch is deactivated. If there is no remote control

module connected as part of the station (repeater only op-

eration) the DMP channel display will show

$0,

but the

station control module will equate this with Channell op-

eration.

4.27 EX DA DT (EXTERNAL DATA DETECT) 6, D2

The EX DA DT bit, when active, can cause the station

control module to mute TX, and/or local, and/or RXI

(Repeater) audios, under code plug programming con-

trol. This bit can allow or disallow selected mixing of these

audios with TX data audio onto the TX modulation audio

line. Which of the three audios is muted depends on

which PTT is keying the transmitter. The intent is to op-

tionally prevent audio from mixing with TX Data audio.

Whether or not mixing occurs is determined by a qualifier

4.28 DW SEL (DIGITAL VOICE PROTECTION

SELECT) 6, Dl

The DVP SEL bit selects either the primary VP code

or the secondary VP subcode from the VP control

module.

4.29 DW C/C (DIGITAL VOICE PROTECTION

CODED/CLEAR) 6, DO

The DVP C/C bit, when active, enables the encryption

and decryption functions of the VP control module.

Therefore, voice is transmitted coded . When inactive,

this bit disables the encryption and decryption functions.

Therefore, voice is transmitted clear .

and

AUX C8, AUX C4, AUX C2,

(AUXILIARY CHANNEL)

D3 TURU

These eight bits determine up to two sets of channels for

the station. A channel is a station state which chooses pre-

defined groups of station parameters such as transmit and

receive frequencies and coded squelch code. The channel

parameters are defined in the station control module

code plug. Also, the station control module code plug

contains the transmit, primary receive, and Channel Scan

parameters. The (second receiver control module) code

plug contains the second receiver parameters. The TX/

RX Channel occupies Address 8, Bits 3-0. The Auxiliary

Channel (Second Receiver and Channel-Scan) occupies

Address 9, Bits 3-0. Optionally, the bits making up the

two channels can be re-grouped to form two different

channels, in which one channel has more. than four bits.

In this optional configuration, the TX/RX Channel least

significant bit (LSB) is at Address

Bit

If more than

four bits are required to form the TX/RX channel repre-

sentation, then those bits are taken from the auxiliary

channel assignments beginning with bit 0 of address 9.

The Auxiliary Channel then starts (LSB) with the next

available bit after the last defined TX/RX channel bit and

continues to bit 3 of address 9. If the two channels are to

be independent, then they cannot share any bits. This

means that the sum of the numbers of bits for the two in-

dependent channels must be eight or less.

These parameter bits are reserved for future applications

or special customer needs.

4.33 REVERSE WILD CARD PARAMETER BITS

Use of the reverse wild card bits (8 bits total, addresses

12 &

13)

requires the wild card module which resides

in the Control Option Tray. The wild card inputs (four

per card) activate or deactivate the appropriate Reverse

wild card MUXbus bit in response to a status signal ex-

ternal to the station. The eight reverse wild card MUX-

bus bits also have an additional definition. They are con-

sidered alarms which, when activated, translate to alarm

tones and are sent to the remote control console via the

outbound wireline. Optionally, the alarm tones may also

be transmitted. The alarms are tone bursts (beeps). The

four bits in Address

are normally defined as internal

alarms and do not require the wild card equipment.

Station conditions which the station control module mon-

7/15/90

itors cause the station control module to write to these

bits which, in tum, send the alarm tones.

NOTE

If the four internal alarm bits of address 12

are activated by the DMP, or some other

control module connected to the MUX-

bus, then the alarm beeps will be activated,

but the actual internal alarm condition will

not be simulated. For example, if the PA

Fail alarm bit (RW2 PA) were to be acti-

vated, two alarm beeps would be sent, but

the PA itself would not be forced to dekey.

The station control module code plug contains information

which determines whether an internal alarm gets written to

the MUXbus, and also if all of the reverse wild card

MUXbus bits will be enabled to activate alarm tones. Thus,

all 8 bits can be configured as external alarm inputs, if de-

sired. The maximum number of internal alarms is four.

The RW4 OVG bit is the battery overvoltage internal sta-

tion alarm parameter, and is activated by the station control

module. RW4 OVG is active when the station battery char-

ger power supply indicates that the external (customer

supplied) station emergency batteries are providing too

much voltage (e.g., are overcharged).

The RW3 SYN bit is the transmit or primary receiver syn-

when either the transmit, primary receive, or both synthesiz-

ers are unlocked.

The RW2 PA bit is the rf power amplifier fail internal station

alarm parameter, and is activated by the station control

module. RW2 PA is active when the rf power amplifier has

failed. A successful keyup or a station control module reset

is required to clear the alarm. The alarm may be active when

the transmitter is de-keyed, due to a prior failure. PA Fail

means that one or both of the station control module PA

status lines (pA On or PA Full Power) are inactive

30-45

msec after the start of a keyup, or for

30-45

msec continu-

ously during keyup, thereafter. RW2 PA is not activated by

the station control module if the PA is not keyed at full pow-

er due to the station control module personality EPROM

rf power cut option. If the station control module service

jumper (JUB01) is installed, the station control module will

activate RW2 PA regardless of the PA status lines. This is

a reminder that the rf power amplifier is operating in a non-

standard manner.

This bit is the battery revert internal station alarm parame-

that the station has lost ac power and has switched to emer-

gency battery backup. RWI BAT becomes inactive as soon

as proper ac power is restored to the station.

Use of the Forward Wild Card bits (up to 8 bits on ad-

dresses 14

puts per card) which resides in the Control Option Tray. Re-

mote wireline control activates these bits. The wild card

control module responds by activating a relay closure or an

open collector output. These closures and/or outputs can

then be used to control equipment external to the station.
