Abstract

A gateway (1000a) is provided including a telephony interface (1004), a network interface (1002), and a digital signal processor (DSP) (1008a) for encoding the incoming telephony channels. The telephony interface (1004) is configured to separate an incoming data stream into separate channels. The telephony interface (1004) is further configured to control operation of a plurality of clocks for synchronizing the transfer of the channels to the encoding DSP, thereby minimizing multiplexing delay. According to another embodiment, the incoming channels are separately initialized by a controller 1050, at a predetermined delay.
