Introduction
The CCU Channel Control Units are used to control functions in a Land Mobile
Radio System such as:
Main / Standby Base
Repeat On/Off
Comparator A / Comparator B
Receive: Normal / Emergency Control Station (ECS)
Transmit: Normal / ECS
The CCU allows three independent consoles to control the above functions. It
allows each console to toggle the functions and provides feedback to the consoles
to indicate the state of each function. If one console fails, the others may continue
to control the system functions.
The CCU provides status indication of each function on the MCN (Monitoring
and Control Network), similar to a CIB module. It also allows the functions to be
toggled from a PC running the MCN Remote Comparator Display (MCNRCD)
software.
The CCU is a CIB Comparator Interface Module with special firmware.
