ABSTRACT:
A system (100) for receiving data from an asynchronous network and transmitting such data onto a synchronous network includes a voice packet buffer memory system (108) with a jitter buffer (118) having groups of entries storing data for voice channels and jitter buffer valid bit (JBVB) memory (120) for status of a particular entry for multiple jitter buffer groups. Writing or reading data from a jitter buffer entry sets a corresponding JBVB memory bit to a valid or invalid state respectively. Jitter buffer data may be read with a corresponding state memory bit. If a corresponding JBVB memory bit is valid, data from a jitter buffer (118) may be provided as an output. If a corresponding JBVB memory bit is invalid, a loss recovery algorithm may compensate for such invalid jitter buffer data.
