Parameter Description
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.
Web: Attenuation Intensity
CLI: acoustic-echo-
suppressor-attenuation-
intensity
[AcousticEchoSuppAttenuati
onIntensity]
Defines the acoustic echo suppressor signals identified as echo
attenuation intensity.
The valid range is 0 to 3. The default is 0.
Web: Max ERL Threshold -
DB
CLI: acoustic-echo-
suppressor-max-ERL
[AcousticEchoSuppMaxERL
Threshold]
Defines the acoustic echo suppressor maximum ratio between signal
level and returned echo from the phone (in decibels).
The valid range is 0 to 60. The default is 10.
Web: Min Reference Delay
x10 msec
CLI: acoustic-echo-
suppressor-min-reference-
delay
[AcousticEchoSuppMinRefD
elayx10ms]
Defines the acoustic echo suppressor minimum reference delay (in 10-
ms units).
The valid range is 0 to 40. The default is 0.
Web: Max Reference Delay
x10 msec
CLI: acoustic-echo-
suppressor-max-reference-
delay
[AcousticEchoSuppMaxRefD
elayx10ms]
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).
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]
Enables Non-Linear Processing (NLP) mode for echo cancellation.
 [0] = (Default) NLP adapts according to echo changes
 [1] = Disables NLP
CLI: echo-canceller-
aggressive-NLP
[EchoCancellerAggressive
NLP]
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].
