User's Manual 54. Configuration Parameters Reference
Version 6.8 783 Mediant 500 E-SBC
Parameter Description
Profile, the settings of this global parameter is ignored for
calls associated with the IP Profile.
Web: Echo Canceler
EMS: Echo Canceller Enable
CLI: echo-canceller-enable
[EnableEchoCanceller]
Global parameter that enables echo cancellation (i.e., echo
from voice calls is removed). You can also configure this
functionality per specific calls, using IP Profiles
(IpProfile_EnableEchoCanceller) or Tel Profiles. For a
detailed description of this parameter and for configuring
this functionality in the IP Profile table, see ''Configuring IP
Profiles'' on page
304 or Tel Profile table, see Configuring
Tel Profiles on page 301 .
Note: If this functionality is configured for a specific profile,
the settings of this global parameter is ignored for calls
associated with the profile.
Web: Echo Canceller Type
CLI: echo-canceller-type
[EchoCancellerType] Defines the echo canceller type.

[0] Line echo canceller = (Default) Echo canceller for
Tel side.

[1] Acoustic Echo suppressor - netw = Echo canceller
for IP side.
EMS: Echo Canceller Hybrid Loss
CLI: 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
EMS: ECN lp Mode
CLI: echo-canceller-NLP-mode
[ECNLPMode]
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.
CLI: 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 this parameter to take effect, a device reset is
required.
CLI: 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
Web: Enable Answer Detector
[EnableAnswerDetector]
Currently, not supported.
Web: Answer Detector Activity Delay
CLI: 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.
