ABSTRACT:
An ATM hub transcoder system (AXC) is coupled to a base station controller (BSC), a mobile switching center (MSC), and a base transceiver subsystem (BTS). In one embodiment, the transcoder system is comprised of an ATM switch subsystem, a transcoder subsystem (XC), a base transceiver subsystem interface (BTSI), and a mobile switching center network interface subsystem (MSC-NI). The ATM switch provides coupling and communication of data in an internal ATM format between each of the XC, BTSI, MSC-NI, and BSC, responsive to control signals from the BSC. The MSC-NI provides for conversion of the format of the data between the internal ATM format and a synchronous format. In one embodiment, the synchronous format is used for communication between the MSC and the NI, responsive to the MSC and the BSC, and the BTSI provides for communicating mobile subsystem information between the BTS and the XC, responsive to the BTS and the BSC. In one embodiment, the interface between the ATM switch and the MSC-NI is PCM encoded in the internal ATM format data. The In an alternate embodiment, the interface between the ATM switch and the BTSI is of digitally encoded voice data in the internal ATM format. The MSC-NI couples the data originating from the MSC via the ATM switch to the transcoder subsystem (XC).
