Abstract:
A network interface (NI) system wherein ATM format encoded data is comprised of control and information data, and wherein control data is provided in the ATM format encoded data, for communicating between an ATM formatted source of encoded data and a circuit formatted source of encoded data, for network interface in a mobile subscriber system having call connectivity management, the network interface system comprising:means for converting received ATM format encoded data, and means for segmenting and reassembling the received data into reconstructed encoded data;means for converting encoded data from the circuit formatted source from a circuit format to an internal ATM format for output; andmeans for converting the received ATM format encoded data to the circuit format for output;wherein the means for converting the circuit format encoded data and the means for converting the received ATM format encoded data are responsive to the reconstructed encoded data for the control data to provide for communication between the ATM formatted source and the circuit formatted source, wherein connectivity and call management are maintainedwherein the NI is coupled to at least one external Mobile Switching Center (MSC); andwherein data from the NI, originating from the at least one external MSC, is coupled via an ATM switch to a transcoder (XC), wherein the XC converts said data to CDMA encoded data and provides an output of transcoded data in the internal ATM format, via the ATM switch, to a base transceiver interface (BTSI), wherein the BTSI provides for conversion from the internal ATM format to a base transceiver system (BTS) format for output to a BTS and therefrom to a mobile subscriber (MS).
