vismAal2CidType3Redundancy
Module: CISCO-VISM-ATM-TRUNK-MIB
OID (symbolic): CISCO-VISM-ATM-TRUNK-MIB::vismAal2CidType3Redundancy
OID (numeric): 1.3.6.1.4.1.351.110.5.5.3.4.1.1.5
Node type: OBJECT-TYPE
Type: TruthValue
Access: read-write
Description: This attribute defines whether the triple redundancy is supported for type 3 packets in AAL2 for this channel. When Triple redundancy is enabled for a channel, the Type 3 packets (CAS bits, dialled digits and user state control packets) are transmitted in triplicates with an interval defined as per the standards I.366.2. For channels which are quite reliable, triple redundancy can be disabled in order to save the bandwidth and the processing overheads.
The default value of this object is 'true(1)' if either vismAal2CidCasTransport or vismAal2CidDtmfTransport is 'true(1)', otherwise the default value is 'false(2)'.
What is vismAal2CidType3Redundancy?
This read-write TruthValue object controls whether triple redundancy is applied to Type 3 packets (CAS bits, dialed digits, user state control) in AAL2 for a given channel, per the I.366.2 standard interval when enabled. Triple redundancy protects critical signaling information from being lost to a single dropped packet, at the cost of extra bandwidth, so disabling it on reliable channels saves capacity. An engineer optimizing bandwidth on a trunk with proven link stability would disable this object on select channels to reclaim bandwidth while accepting slightly higher signaling-loss risk.
