Description
N/A.
Valid Range and Description
Determines the number of spectral coefficients added to an SID packet
being sent according to RFC 3389. Valid only if
EnableStandardSIDPayloadType is set to 1.
The valid values are 0 (default), 4, 6, 8 and 10.
Sets the four wire to two wire worst case Hybrid loss, the ratio between
the signal level sent to the hybrid and the echo level returning from the
hybrid.
[0] = 6 dB (default)
[1] = 9 dB
[2] = 0 dB
[3] = 3 dB
-18 to -3, corresponding to -18 dBm to -3 dBm in 1 dB steps. (Default = -
12 dBm) fax gain control.
[0] = DTMF event is reported on the end of a detected DTMF digit.
[1] = DTMF event is reported on the start of a detected DTMF digit
(default).
Time in msec for generating DTMF tones to the PSTN side (if
TxDTMFOption = 1, 2 or 3).
The default value is 100 msec. The valid range is 0 to 32767.
Time in msec between generated DTMF digits to PSTN side (if
TxDTMFOption = 1, 2 or 3).
The default value is 100 msec. The valid range is 0 to 32767.
[0] = CoderLoopback, encoder-decoder loopback inside DSP.
[1] = PCMLoopback, loopback the incoming PCM to the outgoing PCM.
[2] = ToneInjection, generates a 1000 Hz tone to outgoing PCM.
[3] = NoLoopback, (default).
Determines the Bell modem transport method.
[0] = Transparent (default).
[2] = Bypass.
[3] = Transparent with events.
