Apparatus for placing a plurality of computer-assisted compressed-voice subscriber calls using a circuit-switched signal path in a distributed telecommunications network. A plurality of vocoders receive voice data from respective subscriber voice devices and output substantially continuous compressed-voice data signals which are arranged by a plurality of packetizers into compressed-voice data packets. A plurality of network adapters send the compressed-voice data packets to a circuit-switched telephone network. A plurality of sequencers remove the substantially continuous compressed-voice data signals from the compressed-voice data packets. A multiplexer coupled to the sequencers combines the compressed-voice data signals into a compressed-voice data package and a signal injector injects the compressed-voice data package into a prearranged time slot of a conventional circuit-switched signal path. Upon arrival at the destination, the time slot carrying the compressed-voice data is disassembled and compressed-voice data is routed to destination subscriber premises. Circuit-switched telephone networks can now be employed to carry compressed voice, allowing simultaneous voice and data communications, while still providing low cost and high quality voice service.
