- 948 -
Mediant 4000 SBC | User's Manual
Description
■ [3] = 3 dB
Global parameter enabling Non-Linear Processing
(NLP) mode for echo cancellation.
■ [0] = (Default) NLP adapts according to echo
changes
■ [1] = Disables NLP
Note: If the feature is configured for a specific Tel
Profile, the settings of the global parameter is
ignored for calls associated with the 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 the 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.
