This manual describes the 3000 Series Switch
modules and the alignment instructions for these
modules. This manual is not intended to explain the
®
entire Multi-Net
system, just the 3000-Series Switch
segment. For parts list, schematic diagrams, and
circuit board component layout information, refer to
the 3000 Series Switch Service Manual, Part No. 0013139-102. For more detailed information on the operation of the entire system, refer to Multi-Net Application Note, Part No. 009-3039-004CD.
1.2 DEFINITIONS
The following are brief definitions of terms and
their usage as they are applied to the Switch.
1.2.1 TRUNKED SYSTEM
Refers to systems which pool multiple channels
and use automatic switching so that all system users
can access any repeater channel that is not in use. This
results in minimum waiting to make a call.
1.2.2 LTR TRUNKED SYSTEM
The LTR
®
(Logic Trunked Radio) systems utilize
a concept called trunking. Trunking makes all repeater
channels on a system automatically available to the
users. This is done by logic control system that continually monitors the system and updates the mobiles and
repeaters using data messages. These data messages
tell the mobiles which repeater channels are free and
can be accessed if a call is to be made.
1.2.4 CONVENTIONAL SYSTEM
Refers to systems which are licensed on a single
repeater channel. Operation is similar to that of a
community repeater because there is no automatic
access to several repeater channels.
1.2.5 3000 SERIES SWITCH
The Switch connects several forms of communication together in a “Network” that allows communication between users in the system.
1.2.6 CALL PROCESSOR
The Call Processor controls the databases for the
Switch and provides processing for certain types of
calls within the system.
1.2.7 SYSTEM AND SUBSCRIBER MANAGER
The Switch along with the System and Subscriber
Manager control the Multi-Net System. The System
and Subscriber Manager is an IBM
®
PC or compatible
computer that is running the Johnson management
program. The System and Subscriber Manager is used
by the System Manager to program, control and
continuously monitor Switch operation. Refer to
System and Subscriber Manager Operating Manual,
Part No. 002-3139-078CD for more information.
1.2.8 REPEATER SITE
A location where one or more repeaters are
housed. Trunked system repeaters are connected to the
same high-speed data bus and are required to be
located close together.
1.2.3 MULTI-NET TRUNKED SYSTEM
A trunking system similar to the LTR Trunked
System, but which offers a number of additional and
enhanced features.
1.2.9 HOME REPEATER CHANNEL
All mobiles have one site repeater channel
assigned as their “Home” repeater. The Home
repeater and Group ID information identifies mobiles
for standard dispatch calls.
1-1
INTRODUCTION
1.2.10 STATUS REPEATER CHANNEL
The Status Repeater Channel is one repeater in a
site that is designated to transmit update messages
occurring on all other repeaters at the site. This
repeater is available for voice traffic, but is not
normally assigned as the Home repeater for any
mobiles.
1.2.11 MONITOR REPEATER CHANNEL
This is the repeater channel that a mobile is
currently monitoring for update messages. This
repeater may be either the mobile's Home repeater or
the site Status repeater. A special algorithm is used by
the mobile to determine which is to be monitored.
Generally, it is the last repeater that a valid data
message was detected on.
1.2.12 TELEPHONE INTERCONNECT AND
DATA TRANSMISSION
Mobile transceivers can be used to access the
Public Switched Telephone Network (PSTN) on the
800 and 900 MHz bands. However, this interconnect
operation must be on a secondary basis to dispatch
operation. An exception is when the trunked system or
channel is assigned exclusively to one user. In addition, interconnect calls in a private radio service must
be related to the business activities of the particular
user.
The actual connection to the public telephone
system may take place at any location such as the
repeater or a control station. The interconnect device
can be separate or shared. Timers which limit the
maximum length of transmissions are not required.
However, the equipment must automatically turn off
the transmitter within 3 minutes of the last transmission (except if another dispatch or interconnect call is
initiated within this interval).
Data transmission and paging are also allowed on
these frequencies. It also must be secondary to voice
communication. Refer to applicable FCC rules and
regulations for more information.
1.2.13 PUBLIC SWITCHED TELEPHONE
NETWORK (PSTN)
If interconnect calls are to be placed by mobiles
or landside users to mobiles, the Switch is connected
to the Public Switched Telephone Network. The
specific mobiles which can place calls and other interconnect parameters are determined by how the system
manager programs the Call Processor and by the
programming of each mobile transceiver.
1.2.14 PRIVATE AUTOMATIC BRANCH
EXCHANGE (PABX)
The system has the ability to connect to a PABX
or PBX. This allows mobile originated calls to use the
dial access codes and the least cost routing facility of
the PABX/PBX.

3000 SERIES SWITCH
2.1 INTRODUCTION
A Multi-Net radio system is a combination of
several key elements that together make up a communication system. By using the basic elements of a
Multi-Net system as building blocks, a Multi-Net
system can be designed to meet the communication
needs of almost any type of user. Elements of a MultiNet system are:
• Backbone
This consists of repeater site equipment including
the links to the Switch.
• Control Consoles
Used for dispatch operators.
• Switch
Provides the interface between the Backbone and
Control Consoles.
• RF Equipment
Consists of mobiles, control stations, and handheld
portables.
A Switch contains a Channel Interface Module
(CIM) for each repeater it controls, a Telephone Interconnect Module (TIM) for each telephone line used
for interconnect calls, an Intelligent Dispatch Module
(IDM) or Multi-Net Console Module (MCM) for each
dispatch console and others described in this section.
A single Switch can control up to 30 re peater channels
all at one site or divided among a combination of sites
(e.g. 3-10 channel Localities on one Switch). Each
repeater has an identical Switch interface/logic panel
that performs the call processing for the channel. The
Switch provides interface between the Locality equipment and the control consoles and directs all activity
in Multi-Net site applications.
RF units in the coverage area of one repeater site
can communicate with RF units in the coverage area
of other repeater sites through the Switch. Where more
than 30 channels are required, multiple Switches can
be used with communication between them to direct
calls. Wide area radio coverage is provided to allow a
mobile to talk to another mobile using a repeater
hundreds of miles away. That repeater may be part of
the same Multi-Net system or another Multi-Net
system with phone lines or some other type of link that
provides the communication path.
Each Multi-Net site is an independent trunking
system that processes calls between RF units, maintains fleet partitioning, and provides priority access
control. The backbone elements are interconnected by
either microwave, fiber optics, RF links or private telephone lines equivalent to a 4-Wire voice grade phone
circuit.
One or more dispatch consoles can be connected
to the Switch using; direct connection, phone lines, or
some other type of link. Depending on the capabilities
of the particular console, the dispatcher can perform
such functions as; place calls to specific mobiles, place
calls to other dispatchers, and make a patch between
two mobiles.
• Telephone Interface Module (TIM), to the PSTN or
a PABX.
• System Network Module (SNM), to other SNM,
Switches.
• Network Interface Module (NetNIM), to the Call
Processor.
• Dispatch Channel Module (DCM), to the Conven-
tional Channel, network side.
• Voter Diagnostics Module (VDM), to the Voter
system.
• Power Termination Module (PTM), provides fusing
of power and termination for a shelf.
• Intelligent Dispatch Module (IDM), to the Tracer
Series Dispatch Consoles.
• Logging Encoder Module (LEM), interface to a
logging recorder.
2.3 SWITCH MODULES (ELEMENTS)
The Switch is constructed of different modules
that interface from the Switch to external devices. The
modules are:
• Channel Interface Module (CIM), to the Multi-Net
or LTR System.
• Conventional Channel Module (CCM), to a
Conventional Channel, channel side.
• Dispatch Interface Module (DIM), to the Dispatch
Consoles.
• Multi-Net Acquisition Module (MAM), interface
from the Switch to the VR-CM50 CR T Consoles for
Tone Paging.
• Multi-Net Console Module (MCM), to VRCM-50
CRT Consoles.
• Conventional Patch Module (CPM), to dynamically
patch a single conventional channel to a single
trunked group.
• Wide Area Module (WAM), to other WAMs,
Switches.

The system rack is a framework for modules that
consists of up to two shelves with thirteen slots per
shelf. In each shelf, twelve slots are for function
modules and one slot is reserved for the power
module. The power supplies for the shelves are
located in the lower portion of the rack framework.
The framework also provides support for interconnection wiring, routed between shelves, and external
devices.

normal modules. The total wattage of the terminal is
found by multiplying the wattage of a module by the
number of modules.
Total Watts x No. of Modules = Terminal Power
The wattage required by the power supply is
found by dividing the total wattage of the terminal by
the efficiency of the power supply (0.7).
Terminal Power ÷ 0.7 = Wattage of Power Supply
The BTUs per hour are found by multiplying a known
value (3.6) by the wattage required by the power
supply.
3.6 x Wattage of Power Supply = Btu/Hr.

4.2 FOUR SHELF 3000 SERIES SWITCH
The system rack is a framework for modules that
consists of up to 4-shelves with 13-slots per shelf. In
each shelf, 12-slots are for function modules and
1-slot is reserved for the power module. The power
supplies for the shelves are located in the lower
portion of the rack framework. The framework also
provides support for interconnection wiring, routed
between shelves, and external devices.
4.2.1 POWER CONSUMPTION
The following tables shows the average voltage,
current and power for each supply voltage per card
(based on loading of 48 cards).
Table 4-6 AVERAGE VOLTAGE/CURRENT/
POWER
VoltageCurrentPower
+5V DC0.50A2.50W
+12V DC0.10A1.20W
3.6 x Wattage of Power Supply = Btu/Hr.
EXAMPLE:
4.3W x 48 = 206W
206W ÷ 0.7 = 295W
3.6 x 295W = 1,061 Btu/Hr
4.2.2 EQUIPMENT REQUIRED
• Digital Multimeter, voltmeter resolution to 0.001V.
• Transmission test set, HP 3551A.
• IBM NT compatible computer, with Call Processor
Software.
• Two CIMs (023-3039-035).
4.2.3 4-SHELF POWER SUPPLY
-12V DC0.05A0.60W
-48V DC0.03A*1.44W
Total5.74W
* DIDs only.
Total watts including TIM-DID is 5.74W.
Excluding the TIM-DID provides a total of 4.3W for
normal modules. The total wattage of the terminal is
found by multiplying the wattage of a module by the
number of modules.
Total Watts x No. of Modules = Terminal Power
The wattage required by the power supply is
found by dividing the total wattage of the terminal by
the efficiency of the power supply (0.7).
Terminal Power ÷ 0.7 = Wattage of Power Supply
The BTUs per hour are found by multiplying a known
value (3.6) by the wattage required by the power
supply.
The Power Supply has a 115/230V AC 50/60 Hz
input and 4 continuous duty outputs as follows:
+5V DC 24A.
-5V DC 6A.
+12V DC 3A.
-12V DC 5A.
The power supply can handle 2-shelves and has
the following connections:
4 separate +5V 2A connections.
2 separate -5V connections.
2 separate +12V connections.
2 separate -12V connections.
6 separate ground connections.
4.2.4 POWER SUPPLY REDUNDANT PLATE
The power supply drawer can be made redundant
by the use of the redundant diode plate (PN 023-3039-
553). The redundant plate allows two power supply
drawers to share the load via diodes. One of the power
supply drawers may be removed and the remaining
drawer will supply the full load (see Figure 4-10).

4.3 SIX SHELF 3000 SERIES SWITCH
The system rack is a framework for modules that
consists of up to 6-shelves with 13-slots per shelf. In
each shelf, 12-slots are for function modules and
1-slot is reserved for the power module. The power
supplies for the shelves are located in the lower
portion of the rack framework. The framework also
provides support for interconnection wiring, routed
between shelves, and external devices.
4.3.1 POWER CONSUMPTION
The following tables shows the average voltage,
current and power for each supply voltage per card
(based on loading of 72 cards).
Table 4-11 AVERAGE VOLTAGE/CURRENT/
POWER
The wattage required by the power supply is
found by dividing the total wattage of the terminal by
the efficiency of the power supply (0.7).
Terminal Power ÷ 0.7 = Wattage of Power Supply
The BTUs per hour are found by multiplying a known
value (3.6) by the wattage required by the power
supply.
3.6 x Wattage of Power Supply = Btu/Hr.
EXAMPLE:
4.3W x 72 = 310W
310W ÷ 0.7 = 443W
3.6 x 443W = 1,595 Btu/Hr

SECTION 5 CALL PROCESSOR
CALL PROCESSOR
5.1 INTRODUCTION
The Call Processor controls the databases for the
Switch and provides processing for certain types of
calls within the system. The Call Processor consists of
the following:
• Large Multi-Net Controller (PN 558-3000-126)
• 10 MHz 4-port RS-232 Assembly
(PN 558-3000-122)
• Call Processor Software (PN 023-9998-180).
5.2 DATA BUSES
The Call Processor connects to the system via
five different RS-232 ports. The SMB and SSB
connect the Call Processor to the Switch via the
Network Interface Module (NetNIM). The MAB,
RGB and RMB connect the Call Processor to ancillary
equipment of the overall system. Refer to Figure 5-1.
1. Net Intra-Terminal Data Bus (NetIDB)
The NetIDB is a 9600 baud full duplex port
connected to the Network Interface Module
(NetNIM). The NetNIM buffers the Call Processor
data to the Intra-T erminal Data Bus (IDB). The Call
Processor communicates with the rest of the Switch
modules on the IDB via the NetNIM.
2. Net Channel Status Bus (NetCSB)
The NetCSB is a 9600 baud single data path that
receives data from the NetNIM to the Call
Processor. This data is a “snap shot” of the channel
activity from the Channel Status Bus (CSB) within
the Switch, collected and buffered by the NETNIM
and sent once every two seconds. This information
may be used by an external device to determine
subscriber air time usage. The NetCSB data
protocol and format are available upon request.

CALL PROCESSOR
5.3 CALL PROCESSOR CONTROL
The Call Processor controls several different
databases and secondary functions of the Switch. The
following are some of the major functions of the Call
Processor.
5.3.1 SYSTEM CONFIGURATION
The system configuration provides for initialization of modules and database management. When a
module sends an initialization request to the Call
Processor, the Call Processor searches the configuration database and sends initialization information to
the module. If the module number is not found, the
Call Processor creates an alarm and places the module
in standby mode.
The specific parameters for each module are
contained in the database. Both configuration's database and Switch-to-site setup is viewed or modified
and the channel configuration's loading time is set.
The system analyzer parameters may be viewed and
modified. The system loading may be viewed. The
total configuration database is stored and retrieved
from hard disk or floppy disk.
5.3.3 SUBSCRIBER MANAGEMENT
The Subscriber Management allows an operator
to view, set or modify the Home/Group IDs and the
Unique IDs permissions. Unique IDs may be
controlled for suspend audio, and selective unit disable
(kill).
The Dynamic Reassignment of Unique IDs can
be controlled from the Call Processor. A Unique ID
may be moved to a new System and Group or it may
have the programmable group of a system set to a new
group.
This function allows the following:
1. A Unique ID to be interrogated.
2. The current ID being used on each channel to be
displayed by the operator.
3. Access for each user for Group and Unique IDs can
be set or viewed for RMF control.
4. Passwords for each user may be assigned for RMF
control.
5.3.2 MANUAL DEVICE CONTROL
The manual device control allows the operator to
do the following:
1. Restart single or multiple modules
2. Enable/disable a module from operation
3. Read/write to memory of modules or devices
4. Set date/time.
5. Turn on/off the alarm records storage, activity log,
and screen saver functions
6. Change password.
7. Change the system title of the SMM.
8. Control the receiver voter functions.
9. Control the system analyzer operator by site.
The file management for the above databases is
done by storing and retrieving the files from the hard
disk or floppy disk.
5.3.4 ACTIVITY LOG UTILITIES
The system operator can use the Call Processor
keyboard to enter information messages. The Call
Processor monitor activity window displays alarms
and information for the current day's log and history
files. The activity log contains a time stamp of when
the activity occurred.
5.3.5 CALL COMPLETION
The call completion function handles database
management of trunk assignments and telephon e
number assignments. The trunk assignments may be
viewed, set, stored or retrieved on both hard disk and
floppy disk. The telephone numbers are viewed and
assigned Unique IDs and the telephone assignment
database is stored and retrieved on the hard disk and
floppy disk.
5-2
CALL PROCESSOR
5.3.6 KEYBOARD LOCK
The system operator has the ability to lock the
keyboard by password control to prevent the unauthorized use of the Call Processor. The password is a
single level of control.
5.3.7 LOG OUT/LOG IN
This function allows the operator to log out of
Call Processor thereby locking the keyboard from
unauthorized usage. Once the Call Processor has been
logged out, the function becomes Log In. The log in
function will ask for a password. If the password is
not correct, access is denied.
5.4 ALARM CONTROL
The alarm control is where errors are time
stamped and passed to the activity log function and the
message accounting output function.
5.5 SYSTEM ANALYZER
5.6 CALL PROCESSING
The Call Processor processes Unique ID calls,
telephone calls and group site calls (see Call Sequence Appendix B). Normal dispatch call processing is
handled independently in the associated modules.
The Call Processor determines if an originated
Unique ID call is to be automatically routed or not and
routes the call to the appropriate facility, i.e. DIM or
SNM. The destination Unique ID call is processed by
the Call Processor to determine routing to a DIM or
CIM. Both origination and destination calls are
accounted for and a message accounting record is
generated.
The dialed digits of an incoming telephone call
determine the Unique ID requested and the Call
Processor routes the call to where the Unique ID is
registered. The Call Processor determines if the
Unique ID on an outgoing call has the proper permission for the digits dialed, selects the proper trunk, and
creates a message accounting message.
The Call Processor has the ability to perform an
analysis on the system. This is a complete handshake
(interrogation) of a test mobile in the RF coverage of
sites. This verifies the correct operation of the system
to and from the mobile. The analysis includes all links
including the antenna systems and RF coverage. The
system analyzer has the ability to automatically
disable channels from the system that do not pass the
analysis.
The group site call is routed to the site selected on
origination and creates a message accounting record.
The Call Processor uses the information from the
SSB to validate the use of the system for audio on
Home repeater channel, Group ID sets and Unique
IDs. If an unauthorized user is detected, the Call
Processor intervenes and disconnects the audio being
transmitted from the modules or mobiles.

NETWORK INTERFACE MODULE (NetNIM)
SECTION 6 NETWORK INTERFACE MODULE (NetNIM)
6.1 DESCRIPTION
The NetNIM interfaces the Call Processor to the
internal communication of the Switch. The NetNIM
passes data communication via a 19200 baud full
duplex channel on the Intra-Terminal Data Bus (IDB)
to the Network Intra-terminal Data Bus (NetIDB) at
19200 baud. The NetNIM also passes data between
the Channel Status Bus (CSB) to the Network
Channel Status Bus (NetCSB).
The Master Clock and Master Sync for the PCM
busses are redundant in the NetNIM. A detection
circuit monitors the two different sets and if Master
Clock-A is off frequency, Master Clock-B is activated. If both -A and -B are off frequency, an alarm is
sent to the Call Processor and the NetNIM removes
both sets from distribution in the Switch.
The Switch is allowed a Master and Slave
NetNIM, enabled or disabled from operation on the
data communication path. The master tells the slave
when both of its clocks are off frequency and the
slave clock is distributed, if the slave clocks are on
frequency.
6.2 OPERATION
The NetNIM may be redundant using a master
and slave module. The master is placed in a card slot
with the least significant bit equal to zero. The slave
is placed in a card slot with the least significant bit
equal to one. The NetNIM Master/Slave LED is ON
for master and OFF for slave.
The card slot(s) used for the NetNIM has the
backplane wired for this operation. Refer to Section
23 for further details.

BASIC BOARD MODULE (BBM)
SECTION 7 BASIC BOARD MODULE (BBM)
7.1 DESCRIPTION
The Basic Board Module (BBM) is the mother
board of the following modules:
• Dispatch Interface Module (DIM)
• Intelligent Dispatch Module (IDM)
• Dispatch Channel Module (DCM)
• Channel Interface Module (CIM)
• Telephone Interface Module (TIM)
• System Network Module (SNM)
• Conventional Channel Module (CCM)
• Logging Encoder Module (LEM)
• Voter Diagnostic Module (VDM)
• Multi-Net Console Module (MCM)
• Conventional Patch Module (CPM)
• Wide Area Module (WAM)
7.1.1 MAIN AUDIO
The main external audio connection is via RXA±,
P1, pins 31 and 32, and TXA±, P1, pins 63 and 64.
These connections go to P33. This allows the personality cards to intercept the lines. When a 2-Wire
connection is required on a module, it enters the card
via the RXA± connection. The personality card then
intercepts the signal on P33, pins 2 and 4. The receive
and transmit buffers are connected to the personality
card via P33 also. Refer to the Basic Board Module
block diagram, Figure 7-1.
7.1.2 SECONDARY COMMUNICATION
There is a secondary communication connection
to the BBM. This is used to pass data information to
and from an external device, i.e. the Multi-Net Logic
Module (MLM), another SNM, etc. These connections are the RXS±, P1, pins 27 and 28, and TXS±, P1,
pins 59 and 60. There are two forms of communication on these lines, digital and audio frequency shift
keyed data. The form of communication is determined
by the switch setting of S3 and S4.
These modules are made up of the BBM plus the
appropriate software and personality cards as
required.
The BBM uses four wire audio to connect to the
external equipment. There is an additional connection
for secondary data transmission.
7.1.3 INTERNAL COMMUNICATION
There are several switch selections for the proper
internal routing and use of the audio. This occurs via
switch S1 and J27. There are several internal communication buses that are selected for operation of the
microprocessor. These include both data and audio
buses.

BASIC BOARD MODULE (BBM)
7.3 BBM ALIGNMENT PROCEDURES
7.3.1 INTRODUCTION
The module is designed to operate at a maximum
input level and maintain that level without added
distortion or noise levels significantly different from
the maximum input level. The overall distortion
should be less than 5% with noise less than -45 dB, Cmessage weighted. Adjustments at the maximum
level are difficult due to possible higher distortion and
clipping of the signal, therefore, an average level is
used for alignment. A voice application typically uses
an average level that is -12 dB from the maximum
level. When the module(s) are pre-aligned with the 12 dB average level, the only adjustment necessary is
to set the input and output levels to the -12 dB level.
The module contains operational amplifier stages
with gain that require the absolute alignment level to
be lowered by the gain of the op amp stage. The
module op amp stages have a +9 dBm output swing.
Since the alignment level is -12 dB from maximum,
the absolute average alignment level would be -3 dBm
for a unity gain op amp stage.
The module contains a PCM CODEC chip that
converts the analog audio to digital and back to
analog. The maximum input of the codec is +6 dBm
absolute level since there is a gain of 3 dB in the
circuitry and the output stage can handle +9 dBm
absolute level. The +6 dBm input level requires the
average alignment level to be lower than a -6 dBm
absolute level.
7.3.2 ALIGNMENT
The basic module is pre-aligned with a tone of
1004 Hz at -12 dBm with a 600 ohm driving impedance. The -12 dBm level is verified by measuring the
level across the interface with a high impedance
balanced AC voltmeter. The main audio levels of the
module relative to the input are adjusted to provide
pre-alignment.

CHANNEL INTERFACE MODULE (CIM)
SECTION 8 CHANNEL INTERFACE MODULE (CIM)
8.1 DESCRIPTION
Refer to 3000 Series Switch Service Information
manual, Part No. 001-3139-102, for the component
layout, parts list and schematic. Refer to Figure 7-1
for the Basic Board block diagram. The Channel Interface Module (CIM) connects the Switch to the MultiNet and LTR Repeaters. Each repeater has a CIM that
monitors and controls the repeater through logic
signaling.
8.1.1 REPEATER SIGNALING
The CIM uses one of three methods to exchange
control information with its repeater: RS-232 lines,
Audio Frequency Shift Keying (AFSK) data on a
separate audio path, or by AFSK data in a blank and
burst mode on the voice audio path.
8.1.2 REPEATER CONTROL
The CIM controls the repeater with restart,
enable and disable, executes requests to read and write
to the repeater's memory, and tells the repeater
transmit code, hang or send turnoff. The CIM
receives confirmation of all requests made to the
repeater and sends information the repeater receives.
The status of the CIM/Repeater combination is
determined by the other modules by what the CIM
transmits on the Channel Status Bus (CSB). Th e other
modules monitor the CSB and determine if a CIM has
the appropriate group and status for the type of
communication the module requires.
8.2 CIM SETUP PROCEDURE
8.2.1 SWITCH SETTINGS
Refer to Figure 8-1 for Alignment Points
Diagram.
Command and Control Communication
The command and control communication to the
Multi-Net Logic Module or the Repeater Interface
Module may take place by several different forms.
The form chosen is typically dependent upon the
location of the repeaters to the CIM equipment.
1. If the location is within 200 feet, it is suggested that
the communication take place digitally on the
secondary line.
8.1.3 VOICE CONNECTION
The CIM provides a 4-Wire 600 ohm balanced
voice connection to the repeater, converts audio to and
from Pulse Code Modulation (PCM), transmits and
receives on the PCM buses, and controls voice audio
gating to and from the repeater.
8.1.4 INTERNAL COMMUNICATION
The CIM uses the Intra-T erminal Data Bus (IDB)
to communicate to other modules and send messages
to and receive messages from the Call Processor that
controls its actions.
2. If the location is greater than 200 feet, the communication taking place uses the Audio Frequency
Shift Keyed (AFSK) modems. This may take place
on the Secondary lines if the appropriate facilities
are available; i.e. 4-Wire leased line or microwave
link.
3. The AFSK may be done using the blank and burst
mode on the Main audio lines. This is typically
used when the link is by leased lines or microwave,
but the number of lines available does not allow for
the use of the secondary line connections. (This has
a low level burst of data (100 ms) at the end of transmissions.)

manual, Part No. 001-3139-102, for the component
layout, parts list and schematic. Refer to Figure 7-1 for
the Basic Board block diagram. The Dispatch Interface Module (DIM) uses one of two methods of interface to the dispatch equipment:
1. Direct Connection
2. Tone Remote
A DIM with direct connection is associated with
only one group code and uses a form of Type II E&M
lead input similar to the mobile PTT.
A DIM with tone remote connection decodes
guard tone for the PTT indication and decodes DTMF
to select from one of ten group codes. A control
sequence uses the DTMF to place the DIM in scan
mode or to stop and use a specific group code. The
tone remote feature requires the use of a plug-in
personality card.
1. If the Console is a normal contact closure PTT, the
connection is by direct connect. This uses the E&M
lead input and output.
2. A Tone Remote Console uses 4-Wire audio for the
connection. The DIM requires the use of a tone
remote personality card.

11.2.2 DIM JUMPER PLACEMENT
The DIM connects the 4-Wire 600 ohm balanced
audio with the Pulse Code Modulation (PCM) data
paths and communicates to other modules via the
Intra-Terminal Data Bus (IDB). The DIM also monitors the Channel Interface Module (CIM) Channel
Status Bus (CSB) to determine if a CIM is active with
a DIM group.
11.2 DIM SETUP PROCEDURE
11.2.1 SWITCH SETTINGS
Refer to Figure 11-1 for Alignment Points
Diagram.
Command and Control Communication
The command and control communication to the
Consoles may take the place by two different forms.
The form chosen is typically dependent upon the type
of console connected to the DIM.
