Patent ID: 8260285

Claim:
A handset comprising: a processor configured to perform a diagnostic routine for diagnostic testing of the handset wherein the diagnostic routine generates diagnostic trace information and processes acoustic trace information; a first switch adapted to selectively route the diagnostic trace information or the acoustic trace information received from the processor of the handset, the diagnostic trace information generated in the processor and the acoustic trace information processed in the processor; a codec coupled to the first switch to code the routed trace diagnostic information into coded diagnostic information or to code the routed acoustic trace information received from the processor into coded acoustic information; and a second switch coupled to the codec to selectively route the coded diagnostic information to a bidirectional external acoustic port and to selectively route the coded acoustic information to the bidirectional external acoustic port wherein the bidirectional external acoustic port receives control information to cause the processor to generate the coded diagnostic information and wherein during diagnostic testing audio is forced through the bidirectional external acoustic port disabling real audio capabilities of the bidirectional external acoustic port.
