Version 7.2 1099 Mediant 1000B Gateway & E-SBC
User's Manual 65. Configuration Parameters Reference
Parameter Description
max. echo canceller length of 128 msec.
 When housed with an MPM (in Slot #6), no channel reduction
occurs.
 It is unnecessary to configure the parameter
EchoCancellerLength, as it automatically acquires its value
from the parameter.

echo-canceller-hybrid-loss
[ECHybridLoss]
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

echo-canceller-NLP-mode
[ECNLPMode]
Global parameter enabling Non-Linear Processing (NLP) mode for
the echo cancellation.
You can also configure the functionality per specific calls, using
Tel Profiles (TelProfile_ECNlpMode). For a detailed description of
the parameter and for configuring the functionality in the Tel
Profiles table, see Configuring Tel Profiles on page 459.
Note: If the functionality is configured for a specific Tel Profile, the
settings of the global parameter is ignored for calls associated with
the Tel Profile.
configure voip > media voice >
echo-canceller-aggressive-NLP
[EchoCancellerAggressiveNLP]
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.
configure voip > media RTP-
RTCP > number-of-SID-
coefficients
[RTPSIDCoeffNum]
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].
Answer Detector (AD) Parameters
Enable Answer Detector
[EnableAnswerDetector]
Currently, not supported.
Answer Detector Activity Delay
configure voip > media ipmedia
> answer-detector-activativity-
delay
[AnswerDetectorActivityDelay]
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.
Answer Detector Silence Time
[AnswerDetectorSilenceTime]
Currently, not supported.
Answer Detector Redirection
[AnswerDetectorRedirection]
Currently, not supported.
Answer Detector Sensitivity Defines the Answer Detector sensitivity.
