System Overview
System Overview
The communications control system consists of the Model 4048/4020 Common Control
Equipment (CCE) cabinet and one or more console positions (see Figure 3 ). The CCE
cabinet contains several slots for accepting various types of circuit cards. Types of cards
include Dual Channel Cards (DCCs), Console Interface Cards (CICs), System Traffic
Cards (STCs), Patch Cards, and Auxiliary I/O Cards. The dual channel cards interface the
system to the radio base-stations. The console interface cards interface the system to the
console positions. The STC is the main controller for the system. Patch cards allow the
audio patches to be connected between various channels. The Auxiliary I/O Card adds
external input and output control to the system.
The Model 4048 CCE has 54 card slots (48 usable), supports up to 48 channels, up to 16
console positions, and 1 Patch Card. The Patch Card uses one of the available console
positions.
The Model 4020 CCE has 19 card slots, supports up to 20 channels, up to 6 console
positions, and one Patch Card.
The radio connections at the CCE are made using 25-pair telephone-style cable with 50-
conductor Amphenol-type connectors. The cabinet has one male 50-conductor plug for
every four channels. The radio cables may be routed to a protective punch-down block,
which will protect the equipment from gas-discharge and sneak-current problems.
Consoles may be desktop, rack-mount, or video-display type and may be combined in the
same system. Each type, except the video-display type, consists of a console and up to
three accessory control panels. The basic requirements for each type of console position
are:
Desktop console positions require one Model 4018 Dispatch Console (see Figure 7 ).
Rack-mount console positions require one 4118 Dispatch Console and at least one Model
4115B Console Expander. Two additional Model 4115B Console Expanders may be added
(see Figure 5 and Figure 6 ).
Video display console positions require either one Model 4217B Audio Panel (see Figure
8 ) or a Model 4219 Console Audio Interface (see Figure 9 ), a computer, and a monitor
(see Figure 4 ). A mouse or trackball is normally supplied but is not necessary if the
optional touchscreen is installed. For information about the video display console
positions, refer to the appropriate manual listed in Table 1 .
The CCE is connected to the dispatch console using six pairs of wire, which may be two 6-
conductor modular telephone cables. The dispatch console is connected to the optional
Note
In mixed systems, an Integrator RD video console must be installed
in position 1. This permits various advanced functions to work
properly.
