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.

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 modules in the system are connected by
various busses as described in the following sections.

3.3.1 DATA BUS

• Ethernet Bus

The Ethernet Bus is a broadcast networking tech­nology that can use several different physical media,
including twisted-pair cable and coaxial cable. The
Ethernet bus connects multiple Call Processors and
the System and Subscriber Manager together using
TCP/IP for communication. This allows the Call
Processors and the System and Subscriber Manager to
pass information to keep each other up to date. The
bus passes data for Subscriber Management,
Subscriber Registration, and Switch Configuration
Management.

4.1 TWO SHELF 3000 SERIES SWITCH

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.

4.1.1 POWER CONSUMPTION

The following tables shows the average voltage,
current and power for each supply voltage per card
(based on loading of 24 cards).

Table 4-1 AVERAGE VOLTAGE/CURRENT/

POWER

Voltage

Current Power

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.

EXAMPLE:

4.3W x 12 = 51.6W

51.6W ÷ 0.7 = 73.7W

+5V DC 0.50A 2.50W

+12V DC 0.10A 1.20W

-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

3.6 x 73.7W = 265 Btu/Hr

4.1.2 EQUIPMENT REQUIRED

1. Digi tal Multimet er, voltmeter resolution to 0.001V.

2. Transmission test set, HP 3551A.
