vismAal2CnfPktPeriod
Module: CISCO-VISM-ATM-TRUNK-MIB
OID (symbolic): CISCO-VISM-ATM-TRUNK-MIB::vismAal2CnfPktPeriod
OID (numeric): 1.3.6.1.4.1.351.110.5.5.3.4.1.1.14
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This object is used to configure the packetization period for a given codec. This packetization period has to be a valid entry in the profile table. Profile type and number identify a unique profile table and one codec type in this table might have one or more packetization period. This is applicable only if the vismAal2CidCodecType is 'g729a'.
The configurable values for 'g729a' are 10,20,30 & 40. If a CID entry is configured with a codec other than 'g729a' then the user cannot configure the pkt period for that codec and the pkt period is picked from the profile table.
Hence when we do get/walk on this entry/table any one of the above values could be returned.
What is vismAal2CnfPktPeriod?
This read-write INTEGER object configures the packetization period for a given codec (values five, ten, twenty, thirty, or forty), applicable only when vismAal2CidCodecType is g729a, with valid configurable values of 10, 20, 30, and 40. This setting trades off latency against bandwidth efficiency, since a longer packetization period packs more voice samples per packet and reduces overhead but adds delay. An engineer tuning a bandwidth-constrained G.729a trunk would raise this period toward 40ms to shrink per-call bandwidth, accepting slightly more latency.
