Abstract

A Multiservice Access Concentrator (MAC) is provided at which a dynamic association is established and maintained among a number of processors and a number of voice channels of a data stream. The voice channels are multiplexed voice channels received in a Pulse Code Modulation (PCM) data stream. The processors comprise digital signal processors (DSPs) for performing compression and decompression of the plurality of voice channels. A table is generated that tracks the association among the plurality of processors and the plurality of voice channels. At least one signal is generated that synchronizes a transfer of data among each of the processors and the associated voice channels. The generation of at least one signal comprises providing a frame synchronization signal to each of the processors to indicate the start of a first voice channel. Furthermore, a byte synchronization signal is provided to each processor when the associated voice channel is available for transfer. Moreover, a clock gating control signal is provided to each of the processors when the associated voice channel is available for transfer. A number of compressed voice channels are provided to at least one multi-service network using a configurable trunk, wherein the at least one multi-service network comprises Asynchronous Transfer Mode (ATM), Frame Relay, High-level Data Link Control (HDLC), Internet Protocol (IP), and TDM networks.
