vismCodecJitterDelayMode
Module: CISCO-WAN-CODEC-GEN-PARM-MIB
OID (symbolic): CISCO-WAN-CODEC-GEN-PARM-MIB::vismCodecJitterDelayMode
OID (numeric): 1.3.6.1.4.1.351.150.21.1.1.1.1.2
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This object is used to provision the jitter buffer mode to be apply to a call connection. The possible values are: 'fixed' : means use a constant jitter buffer size, which is defined by the vismJitterInitialDelay (specify in CISCO-VISM-MODULE-MIB MIB) variable. The DSP will be instructed to use fixed with no time-stamps mode. 'adaptive': means let the DSP pick the optimal value for the call connection.
'fixedWithTimeStamp': means use a constant jitter buffer size, which is defined by the vismJitterInitialDelay variable. The DSP will be instructed to use fixed with time-stamps mode.
For 'g711u', 'g711a', 'clearChannel', and 'lossless' the default value is fixed.
For 'g726r32000', 'g729a', 'g729ab', 'g726r16000', 'g726r24000','g726r40000', 'g723h','g723l', 'g723ah' and 'g723al' the default value is adaptive.
What is vismCodecJitterDelayMode?
This read-write object provisions the jitter buffer mode applied to a VISM voice call connection, with fixed using a constant buffer size defined by vismJitterInitialDelay, adaptive letting the DSP pick and adjust an optimal size dynamically, and fixedWithTimeStamp instructing the DSP to use a fixed buffer with time-stamps. An administrator chooses the mode based on the network's jitter characteristics for voice traffic. For example, a link with highly variable delay would benefit from the adaptive mode so the DSP can continually adjust buffering to minimize both jitter artifacts and added latency.
