Parameter Description
and/or a Tel Profile.
Web: Max Echo Canceller
Length
[MaxEchoCancellerLength]
Defines the maximum Echo Canceler Length (in msec), which is
the maximum echo path delay (tail length) for which the echo
canceller is designed to operate:
 [0] Default = (Default) Based on various internal device
settings to attain maximum channel capacity
 [11] 64 msec
 [22] 128 msec
Notes:
 For this parameter to take effect, a device reset is required.
 Using 128 msec may reduce channel capacity. For example:
with DSP Template 0 and number of spans 4, the capacity is
reduced from 120 to 100. The reduction depends on the
combination of “DSP Template” and “Number of Spans”. For
accurate figures, see DSP Templates on page 695.
 It is unnecessary to configure the parameter
EchoCancellerLength, as it automatically acquires its value
from this parameter.
EMS: 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
[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.
[EchoCancellerAggressiveNL
P]
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.
[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].
