A single-chip network processor ( 12 ) for a Voice-over-Internet Protocol phone integrates a universal serial bus port ( 21 ), a pair of IEEE 802.3 MACs ( 40 ), and repeater, and a pair of pulse code modulation (PCM) ports ( 24 ) such that the network processor can be easily combined with other peripherals to transmit both voice and computer data over an Internet protocol network.
