User's Manual
Description
Defines the acoustic echo suppressor minimum reference
delay (in 10-ms units).
The valid range is 0 to 40. The default is 0.
Defines the acoustic echo suppressor maximum reference
delay (in 10-ms units).
The valid range is 0 to 40. The default is 40 (i.e., 40 x 10 =
400 ms).
Defines 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] = (Default) 6 dB

[1] = N/A

[2] = 0 dB

[3] = 3 dB
Defines the echo cancellation Non-Linear Processing
(NLP) mode.

[0] = (Default) NLP adapts according to echo changes

[1] = Disables NLP

[2] = Silence output NLP
Note: This parameter can also be configured in a Tel
Profile.
Enables the Aggressive NLP at the first 0.5 second of the
call.

[0] = Disable

[1] = (Default) Enable. The echo is removed only in the
first half of a second of the incoming IP signal.
Note: For this parameter to take effect, a device reset is
required.
Defines the number of spectral coefficients added to an
SID packet being sent according to RFC 3389.
The valid values are [0] (default), [4], [6], [8] and [10].
Currently, not supported.
Defines the time (in 100-msec resolution) between
activating the Answer Detector and the time that the
detector actually starts to operate.
The valid range is 0 to 1023. The default is 0.
Currently, not supported.
Currently, not supported.
Defines the Answer Detector sensitivity.
The range is 0 (most sensitive) to 2 (least sensitive). The
default is 0.
