4.5Cell Link Unit - CLU (REX-BRD0014 or ROFNB 157 11/2) or

CLU-S (REX-BRD0016 or ROFNB 157 16/2)

The CLU interfaces between a SPU and a Base Station. Every CLU board contains eight CLC (see Figure 4-3). Each CLC communicates with one Base Station.

The main functions of the board are:

zProvides eight simultaneous speech channels from the RE to a Base Station.

zProvides TDMA frame synchronization and power for the Base Stations.

The Base Station control, TDMA frame generation and radio link maintenance functions are implemented in the Base Station.

For signalling distances up to 2.2 miles, a CLU may be used with appropriate powering and cable types. For signalling distances up to 1.2 miles, a CLU-S may be used with appropriate powering and cable types.
