The STS-1 outputs from the demultiplexer are sent to the STS-1 pointer processor
which performs pointer interpretation and generation on each received STS-1.
The output of the STS-1 pointer processor is three STS-1 signals, frame
synchronous to each other. STS-1s are passed through without STS-1 path
overhead termination. The cross connect sends each of the three STS-1 signals
to the function unit slots.
