vismJitterInitialDelay
Module: CISCO-VISM-MODULE-MIB
OID (symbolic): CISCO-VISM-MODULE-MIB::vismJitterInitialDelay
OID (numeric): 1.3.6.1.4.1.351.110.3.17.3.6
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Defines the jitter buffer size. If the vismJitterDelayMode is set to be fixed, the jitter buffer is fixed at this value for the call. If vismJitterDelayMode is adaptive, this is the initial jitter buffer size, and the DSP will adapt to an optimal size.
The valid range for template 1 : 1,10,20,30,40,50,60,70, 80,90,100 The valid range for template 2 : 1,5,10,15,20,25,30,35, 40,45,50,55,60,65,70, 75,80,85,90,95,100.
When the template of the card changes, either from template 1 to 2 or vice versa the value of this object will be implicitly set to default value.
What is vismJitterInitialDelay?
This INTEGER sets the jitter buffer size for a call, used as the fixed size when vismJitterDelayMode is fixed, or as the starting point the DSP adapts from when the mode is adaptive, with the valid discrete values depending on which template is in use. This directly trades off latency against resilience to network jitter, so an admin tunes it based on how much delay variation the network path actually exhibits. For example, an admin on a network with noticeable jitter might raise vismJitterInitialDelay to reduce audio choppiness, accepting a bit more overall call latency in exchange.
