Version 6.8 607 Mediant 2600 E-SBC
User's Manual 43. Configuration Parameters Reference
43.9 Channel Parameters
This subsection describes the device's channel parameters.
43.9.1 Voice Parameters
The voice parameters are described in the table below.
Table 43-33: Voice Parameters
Parameter Description
Web/EMS: Input Gain
CLI: input-gain
[InputGain]
Global parameter that defines the pulse-code modulation (PCM) input
(received) gain control level (in decibels). You can also configure this
functionality per specific calls, using IP Profiles (IpProfile_InputGain).
For a detailed description of this parameter and for configuring this
functionality in the IP Profile table, see ''Configuring IP Profiles'' on
page 297.
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: Voice Volume
EMS: Volume (dB)
CLI: voice-volume
[VoiceVolume]
Global parameter that defines the voice gain control (in decibels). This
defines the level of the transmitted (IP-to-) signal. You can also
configure this functionality per specific calls, using IP Profiles
(IpProfile_VoiceVolume). For a detailed description of this parameter
and for configuring this functionality in the IP Profile table, see
''Configuring IP Profiles'' on page 297.
Note: If this functionality is configured for a
specific profile, the settings
of this global parameter is ignored for calls associated with the profile.
EMS: Payload Format
CLI: G726-voice-payload-
format
[VoicePayloadFormat]
Determines the bit ordering of the G.726 voice payload format.
[0] = (Default) Little Endian
[1] = Big Endian
Note: To ensure high voice quality when using G.726, both
communicating ends should use the same endianness format.
Therefore, when the device communicates with a third-party entity that
uses the G.726 voice coder and voice quality is poor, change the
settings of this parameter (between Big Endian and Little Endian).
Web: MF Transport Type
CLI: MF-transport-type
[MFTransportType]
Currently, not supported.
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). For a detailed
description of this parameter and for
configuring this functionality in the
IP Profile table, see ''Configuring IP Profiles'' on page 297.
Note: If this functionality is configured for a specific profile, the settin
of this global parameter is ignored for calls associated with the profile.
Web: Network Echo
Suppressor Enable
CLI: acoustic-echo-
suppressor-enable
[AcousticEchoSuppressorSu
pport]
Enables the network Acoustic Echo Suppressor feature on SBC calls.
This feature removes echoes and sends only the near-end’s desired
speech signal to the network (i.e., to the far-end party).
[0] Disable (default)
[1] Enable
Note: For this parameter to take effect, a device reset is required.
