Abstract:
A system for interworking digital simultaneous voice and data (DSVD) modems with a radio telecommunications network having a mobile switching center (MSC) which communicates with a mobile station utilizing a circuit mode Radio Link Protocol (RLP), said system comprising:a DSVD modem associated with said mobile station, said DSVD modem generating DSVD source signal and line negotiation protocols;means for encapsulating DSVD source signal and line negotiation protocols without modification into circuit mode RLP signals, said means for encapsulating including means for multiplexing said DSVD source signal and line negotiation protocols into a single voice channel;an interworking function associated with said MSC for translating said circuit mode RLP signals into signals in a landline telecommunications protocol; andmeans for modulating and transmitting said signals in a landline telecommunications protocol to a landline telecommunications network.
