CHAPTER 60 Configuration Parameters Reference
Mediant 4000 SBC | User's Manual
Table 60-39:IP Media Parameters
Parameter Description
'IPMedia Detectors'
configure voip > media
ipmedia > ipm-detectors-
enable
[EnableDSPIPMDetectors]
Enables the device's DSP detectors for detection
features such as AMD.
■ [0] Disable (default)
■ [1] Enable
Note:
■ For the parameter to take effect, a device reset is
required.
■ The DSP Detectors feature is available only if the
device is installed with a License Key that includes
this feature. For installing a License Key, see
License Key .
'Number of Media Channels'
configure voip > sbc
settings > media-channels
[MediaChannels]
Defines the maximum number of DSP channels that
can be used for features requiring DSP resources, for
example, coder transcoding, DTMF transcoding, and
answer machine detection (AMD).
The default is -1, meaning the maximum DSP
channels, as defined by the License Key (“DSP
Channels”).
Note:
■ Most SBC features that require DSP resources
use two DSP channels. For example, if the device
needs to perform coder transcoding between two
endpoints where one uses the G.711 coder and the
other uses G.729, and a maximum of 100
concurrent transcoding sessions need to be
supported, the device would use 200 DSP
channels. For this scenario, you would configure
the parameter to 200.
■ In some scenarios, the device may not have
sufficient DSP resources to process the number of
transcoding sessions as configured by the
MediaChannels parameter.
■ If you modify the parameter to a value that is less
than the number of DSP channels currently being
used by the device for currently active calls, the
device allows these calls to continue (and does not
terminate them).
Automatic Gain Control (AGC) Parameters
'Enable AGC'
configure voip > media
ipmedia > agc-enable
[EnableAGC]
Global parameter enabling the AGC feature.
Enables the AGC mechanism. The AGC mechanism
adjusts the level of the received signal to maintain a
steady (configurable) volume level.
■ [0] Disable (default)
■ [1] Enable
For a description of AGC, see Automatic Gain Control
(AGC) .
