Abstract:
1. An apparatus, comprising: a line unit and a compressed-voice module, wherein the compressed-voice module comprises a sequencer and a packet separator coupled to said sequencer; wherein said packet separator receives data packet traffic from an originating subscriber premises, wherein the data packet traffic comprises compressed-voice data packets and second data packets; wherein said compressed-voice data packets have a first identifying header; said second data packets have a second identifying header; and said packet separator diverts said second data packets from said compressed-voice data packets upon detection of the second identifying header; wherein said sequencer extracts first compressed-voice data signals from the compressed-voice data packets; the apparatus further comprising a multiplexer that combines a plurality of substantially continuous compressed-voice data signals from a plurality of respective originating subscriber premises into a compressed-voice data package, wherein the plurality of respective originating subscriber premises comprise the originating subscriber premises, wherein the plurality of substantially continuous compressed-voice data signals comprise the first compressed-voice data signals from the sequencer; and a signal injector injecting said compressed-voice data package into a prearranged time slot, of a circuit-switched, time division multiplexed (TDM) signal path of a public switched telephone network (PSTN), that is dedicated for the compressed-voice data package; the apparatus further comprising a switching module of a local switching office of the PSTN, wherein the switching module comprises the line unit, the compressed-voice module, the sequencer, the multiplexer, and the signal injector.
