Description: Voice DSP jitter buffer size in milliseconds. More specifically, it refers to the amount of memory usage that can store certain milliseconds of voice.
There are two types of jitter algorithms: static and dynamic. Dynamic allows the jitter buffer to grow and shrink as inter-arrival jitter changes. A static jitter buffer does not.
When the jitterBufferType is dynamic, jitterBufferSize is the initial buffer size the jitter buffer can grow to.
Some examples of the voice connection types used for; Voice Over ATM (VoATM): pots-to-aal2, isdn-to-aal2, aal2-to-gr303, aal2-to-v52. Voice Over IP (VoIP) : sip-to-ds1, sip-to-gr303, sip-to-v52.
Valid range is 1 to 33 milliseconds for VoATM case.
Valid range is 1 to 100 milliseconds for VoIP case.
Default jitter buffer size is 10 milliseconds.
What is jitterBufferSize?
Sets the default jitter buffer size in milliseconds (0-300, though the valid range is narrower per connection type -- roughly 1-33ms for VoATM and 1-100ms for VoIP, default 10ms). For a dynamic jitter buffer, this value is just the starting size it can grow beyond as needed.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.5504.4.3.3.1.3 snmpwalk -v2c -c public <target> ZHONE-COM-VOICE-DSP-MIB::jitterBufferSize
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.5504.4.3.3.1.3.1 snmpget -v2c -c public <target> ZHONE-COM-VOICE-DSP-MIB::jitterBufferSize.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.5504.4.3.3.1.3.1 i <value>
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> jitterBufferSize.1
