Local Control Module Description 
The local control module locally monitors the following node voltages and signals: 
 
Receiver optical input level (all receivers) 
 
Transmitter optical output level (all transmitters) 
 
AC power presence and peak voltage (for split AC powering cases, AC 
power from both sides of node housing is monitored) 
 
DC voltages from both primary and redundant power supplies 
 
Optical amplifier operating parameters 
 
Optical switch operating parameters 
The local control module communicates serially with the RF amplifier module to 
control the optional forward band redundancy switches on the forward
