Series 4000 Communications Control System



Communications Control System Series 4000

The Series 4000 is a communication control system designed for medium-sized communications centers. In addition to exceptional reliability, the Series 4000 offers easy programming and economical upgrades.

Unique Series 4000 capabilities include CRT based operator positions, trunked radio compatibility, and an integrated instant recall recorder that captures radio traffic on each channel.

Featuring three styles of operating positions and two common controller sizes, a Series 4000 system can be economically scaled to accommodate from 8 to 48 channels and from 1 to 16 operator positions.

Common Control Units

A Common Control Unit (CCU) is the central controller responsible for switching and routing multiple audio channels between operating positions and the external devices such as base stations, control stations, repeaters, telephones, monitor receivers, and intercoms.
The Series 4000 offers two different Common Control Units to accommodate different capacity requirements.
