ABSTRACT:
In a PCM switching system having a CPU controlled switching network, a reformatting circuit is connected between the switching network and a number of digital spans. The reformatting circuit converts supervisory data which is serially received to parallel data words which may be readily accessed by the CPU. The supervisory data is logically ordered and stored in a memory for CPU access.
