Transmit OGM voice stream. During voice
stream capture, the user can adjust the
UB3 value via the <DLE><u> and
<DLE><d> commands. The host voice
driver will need track the number of adjust-
ments and update the +VGT value for
future use.
Terminate the transmit operation. The
modem will respond with OK to denote the
return to command mode.
Select G.726 ADPCM, 4-bit, 32 kbps for-
mat.
Play user record tone prompt.
Restore DAA-to-Si3000 receive gain path.
This will allow call screening of the ICM.
Enable speaker for call screening of the
ICM.
Trigger receive operation. The first byte
after the newline character following the
CONNECT message will be the first data
stream byte.
Receive ICM voice stream. During voice
stream capture, the user can adjust the
UBF value via the <DLE><u> and
<DLE><d> commands. The host voice
driver will need track the number of adjust-
ments and update the +VGR value for
future use.
Terminate the receive operation. The
modem will respond with <DLE><ETX> to
mark the end of the data stream. The OK
denotes the return to command mode. A
loss of loop current, parallel phone detect,
timeout, or silence event can trigger the
<DLE><!> transmission.
