SECTION 1 INTRODUCTION

INTRODUCTION

1.1 SCOPE OF MANUAL

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.

SECTION 2 3000 SERIES SWITCH

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.

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.

-12V DC 0.05A 0.60W

-48V DC 0.03A* 1.44W

Total 5.74W

* 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-

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.)

SECTION 9 CONVENTIONAL CHANNEL MODULE (CCM)

9.1 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 Conventional Channel Module (CCM) connects the Switch to a Conventional Repeater. Each repeater has a CCM that controls the repeater through logic signaling.

9.1.1 REPEATER SIGNALING

The CCM exchanges control information with the CRM via Audio Frequency Shift Keying (AFSK) data in a blank and burst mode on the voice audio path.

9.1.2 REPEATER CONTROL

The CCM monitors and controls the repeater transmit, receives confirmation of all requests made to the repeater and sends information the repeater received.

9.1.3 VOICE CONNECTION

9.2 CCM SETUP PROCEDURE

9.2.1 CCM SWITCH SETTINGS

Refer to Figure 9-1 for Alignment Points

Diagram.

Command and Control Communication

The command and control communication to the Conventional Repeater Module (CRM) is by blank and burst mode of Audio Frequency Shift Keyed data on the Main audio lines.

9.2.2 AFSK COMMUNICATION ON THE MAIN

LINES

Refer to Table 9-1 for switch settings.

Table 9-1 CCM SWITCH SETTINGS

Switch Open Sections Close Sections

The CCM 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.

9.1.4 INTERNAL COMMUNICATION

The CCM uses the Intra-Terminal Data Bus (IDB) to communicate to other modules and send messages to and receive messages from the Call Processor that controls its actions.

The status of the CCM/CRM/Repeater combination is determined by the other modules by what the CCM transmits on the Channel Status Bus (CSB). The other modules monitor the CSB and determine if a CCM has the appropriate group and status for the type of communication the module requires.

DISPATCH INTERFACE MODULE (DIM)

SECTION 11 DISPATCH INTERFACE MODULE (DIM)

11.1 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 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.
