Introduction
Figure 1: Model 4048 Common Control Equipment
The Model 4020 Common Control Equipment provides the same functionality as the
Model 4048, but is configured for smaller systems. A Model 4020 system contains up to
19 modular circuit cards. It handles a maximum of twenty radio channels and six dispatch
console positions.
The CCE resides in a standard open-frame or fully enclosed 19-inch EIA equipment rack
(not included as part of the system) and is typically located in a back room away from
traffic and dust. The choice of an open or enclosed rack depends on the location and
whether or not additional air filtration is required. The CCE consists of a set of modular
19-inch rack mounted components. Depending on configuration, the Model 4048 CCE
requires between 36.75 and 56 inches of vertical rack space. The Model 4020 CCE
requires a minimum of 17.5 inches of vertical rack space.
