PH-PC36

Multiplexer

1. General Function

The PH-PC36 (MUX ) circuit card i s an i nterface card f or mounting line circuits and/or trunks. In between

the CPR and the Port Microprocessor (PM) of the line/t runk circuit, this circuit card provides an interface

for P M control and manage ment by the CPU. Like wise in between t he TSW and the li ne ci rcuit /trunks, this

circ uit card pro vides an interface for mult iplexing/ de-multiplexi ng of vo ice Pulse Code Modulati on (PCM)

information and digital data information.
