ABSTRACT:
Apparatus for switching full-rate (e.g., 64 kilobit per second) signals and composite signals comprising a plurality of sub-rate signals (e.g., 32 kilobit per second sub-rate signal). The apparatus includes a unit for compressing selected ones of a plurality of full rate signals into a smaller plurality of full rate single and composite signals, and apparatus for expanding composite signals into full rate signals. Advantageously, during periods of heavy load, the switching network fabric of a switching system can carry more calls, and more traffic can be carried between switches equipped for sub-rate switching.
