ABSTRACT:
An N:1 data compression system for compressing data on N DS1 trunks carrying 4N channels is disclosed. Waveform encoding circuitry is coupled to the N DS1 trunks for compressing the DS1 data into x bits and producing both encoded data and control parameters, where x.ltoreq.8. The system further includes circuitry coupled to the waveform encoding circuitry for receiving the encoded data and control parameters, performing digital speech interpolation and producing data packets which may include encoded data and control parameters that are transmittable on a single DS1 trunk.
