Voice AT Commands

The following is a summary of voice AT commands supported by the Omni 288:
Chapter 10 - Voice Mode Operation
Event Report Description
Turn up the volume or gain by one unit.
Turn down the volume or gain by one unit.
Pause Data State: The DCE suspends sending analog data to the
currently selected analog destination. While pausing, the DCE will
maintain the contents of its internal buffer and the state of its
compressors, continue in the Data State, and send silence to the
analog destination.
Resumes Data Transmission State: The DCE resumes sending
the contents of the DCE buffer to the currently selected analog
destination. Before resuming sending the analog signal to the
analog destination, the DCE will not reset the contents of its
internal transmission buffer, nor reset the compressors.
Ends Data Transmission State: The DTE sends this code to
signify the end of the voice data from the DTE and cause the
DCE to return to the Voice Command State. The DCE will
complete the transmission of the contents of its buffer before
switching to the Voice Command State and returning the OK
result code
Clears the transmission buffer of voice data and ends Data
Transmission State: The DTE sends this code to indicate the end
of the voice data from the DTE and cause the DCE to return to
the Voice Command State. The DCE will clear its internal
transmission buffer before switching to the Voice Command State
and returning the OK result code.
Clears the transmission buffer of voice data: This code
commands the DCE to (1) clear its internal transmission buffer;
(2) get ready for a new voice data stream with the same
parameters as the last stream; and (3) reset its compressors and
send silence over to the analog destination while paused.
Concatenate data streams: The DTE sends this code to indicate
the start of a new voice data stream with the same parameters as
the last stream without first returning to the Voice Command
State. The DCE will transmit the remainder of its internal
transmission buffer and reset its compressors before transmitting
the data following the <DLE><FS> or <DLE><DC2> codes.
Ends Data Reception State. The DTE sends this code to indicate
the end of voice data reception and the return to Voice Command
State. The DCE will discard the contents of its buffer before
switching to the Voice Command State and returning the OK
result code.
