Mediant 1000B Gateway & E-SBC
Parameter Description
Note: The corresponding global parameter is
PremiumServiceClassControlDiffServ.
Jitter Buffer
Dynamic Jitter Buffer
Minimum Delay
jitter-buffer-minimum-delay
[IpProfile_JitterBufMinDelay]
Defines the minimum delay (in msec) of the device's dynamic Jitter
Buffer.
The valid range is 0 to 150. The default delay is 10.
For more information on Jitter Buffer, see Configuring the Dynamic
Jitter Buffer on page 199.
Note: The corresponding global parameter is DJBufMinDelay.
Dynamic Jitter Buffer
Optimization Factor
jitter-buffer-optimization-factor
[IpProfile_JitterBufOptFactor]
Defines the Dynamic Jitter Buffer frame error/delay optimization
factor.
The valid range is 0 to 12. The default factor is 10.
For more information on Jitter Buffer, see Configuring the Dynamic
Jitter Buffer on page 199.
Note:
 For data (fax and modem) calls, set the parameter to 12.
 The corresponding global parameter is DJBufOptFactor.
Jitter Buffer Max Delay
jitter-buffer-max-delay
[IpProfile_JitterBufMaxDelay]
Defines the maximum delay and length (in msec) of the Jitter Buffer.
The valid range is 150 to 2,000. The default is 250.
Voice
Echo Canceler
echo-canceller
[IpProfile_EnableEchoCancell
er]
Enables the device's Echo Cancellation feature (i.e., echo from voice
calls is removed).
 [0] Disable
 [1] Line (default)
For a detailed description of the Echo Cancellation feature, see
Configuring Echo Cancellation on page 187.
Note: The corresponding global parameter is EnableEchoCanceller.
Input Gain
input-gain
[IpProfile_InputGain]
Defines the pulse-code modulation (PCM) input gain control (in
decibels). For the Gateway application: Defines the level of the
received signal for Tel-to-IP calls.
The valid range is -32 to 31 dB. The default is 0 dB.
Note: The corresponding global parameter is InputGain.
Voice Volume
voice-volume
[IpProfile_VoiceVolume]
Defines the voice gain control (in decibels). For the Gateway
application: Defines the level of the transmitted signal for IP-to-Tel
calls.
The valid range is -32 to 31 dB. The default is 0 dB.
Note: The corresponding global parameter is VoiceVolume.
SBC Signaling
PRACK Mode
sbc-prack-mode
[IpProfile_SbcPrackMode]
Defines the device's handling of SIP PRACK messages for the SIP
entity associated with the IP Profile.
 [1] Optional = PRACK is optional. If required, the device performs
the PRACK process on behalf of the SIP entity.
 [2] Mandatory = PRACK is required for this SIP entity. Calls from
endpoints that do not support PRACK are rejected. Calls destined
