Patent ID: 7403141

Claim:
A Wireless Local Area Network (WLAN) transceiving integrated circuit that services voice communications in a WLAN with at least one WLAN device, the WLAN transceiving integrated circuit comprising: a WLAN interface that wirelessly communicates with the at least one WLAN device to receive inbound packetized audio data from the at least one WLAN device and to transmit outbound packetized audio data to the at least one WLAN device; a transcoder operably coupled to the WLAN interface, wherein the transcoder receives the inbound packetized audio data and converts the inbound packetized audio data to inbound Pulse Code Modulated WLAN audio data, and wherein the transcoder receives outbound PCM WLAN audio data and converts the outbound PCM WLAN audio data to the outbound packetized audio data; and a switch box operably coupled between the transcoder and a PCM bus, the switch box including: a plurality of switch box inputs that receive the inbound PCM WLAN audio data and outbound PCM bus audio data; a plurality of switch box outputs that produce the outbound PCM WLAN audio data and inbound PCM bus audio data; and signal selection and combining circuitry operably coupled to the plurality of switch box inputs and to the plurality of switch box outputs that controllably combines at least two switch box inputs of the plurality of the switch box inputs to produce one switch box output of the plurality of switch box outputs.
