System including a communication apparatus having a digital audio interface for audio testing with radio isolation

A system comprising:

• a communication apparatus;
• a test subsystem configured to initiate an audio test of the communication apparatus, wherein the test subsystem is configured to receive in response to the audio test a set of audio test data at a predetermined constant data rate and wherein the communication apparatus is configured to alternately enable and disable the output of the set of audio test data during the audio test;
• and
• a converter coupled to receive the set of audio test data output from the communication apparatus and configured to provide the set of audio test data to the test subsystem at the predetermined constant data rate.

A system comprising:

• a communication apparatus including a radio frequency (RF) circuit coupled to a digital processing circuit;
• a test subsystem configured to initiate an audio test of the communication apparatus, wherein the test subsystem is configured to transmit a set of audio test data at a predetermined constant data rate and receive in response acoustic audio transmissions from the communication apparatus;
• and
• a converter coupled to receive the set of audio test data output from the test subsystem at the predetermined constant data rate;
• wherein the communication apparatus is configured to cause the converter to transmit the set of audio test data to the communication apparatus during inactive periods of operation of the RF circuit and suspend the transmission of the set of audio test data to the communication apparatus during active periods of operation of the RF circuit.

A method of performing an audio test of a communication apparatus, the method comprising:

• providing a signal to initiate the audio test from a test subsystem that is configured to receive a set of audio test data in response to the audio test at a predetermined constant data rate;
• generating a set of audio test data in response to the signal;
• alternately enabling and disabling the output of the set of audio test data from the communication apparatus to a converter during the audio test;
• transmitting the set of audio test data from the converter to the test subsystem at the predetermined constant data rate.

A method of performing an audio test of a communication apparatus, the method comprising:

• transmitting a set of audio test data from the test subsystem at a predetermined constant data rate;
• buffering the set of audio test data in a converter;
• alternately enabling and disabling a transmission of the set of audio test data from the converter to the communication apparatus;
• generating an acoustic audio output from the communication apparatus in response to receiving the set of audio test data;
• and
• providing the acoustic audio to the test subsystem.
