t38HsDataRedundancy
Module: CISCO-WAN-T38-FAXRELAY-MIB
OID (symbolic): CISCO-WAN-T38-FAXRELAY-MIB::t38HsDataRedundancy
OID (numeric): 1.3.6.1.4.1.351.150.19.1.1.1.1.6
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description: This object determines the extent of the IFP packet transmission redundancy for the high-speed control and image information exchanged following the initial low-speed phase of a T.38 fax relay connection.
Depending on whether FEC is enabled via the t38ErrorCorrection object, t38HsDataRedundancy has different meanings.
If FEC is disabled, then t38HsDataRedundancy is the maximum number of prior IFP packets within a UDPTL packet carrying high speed information, not counting the primary or current IFP packet.
If FEC is enabled, then t38HsDataRedundancy is the maximum number of FEC messages within a UDPTL packet carrying high speed information.
What is t38HsDataRedundancy?
This read-write Integer32 (0-2147483647) controls the extent of IFP packet transmission redundancy for the high-speed control and image data exchanged after the initial low-speed phase of a T.38 fax relay connection, with its precise behavior again depending on the t38ErrCorrection (FEC) setting. An admin increases it to protect the bulk of the fax's actual image data against loss on an unreliable IP path. For example, raising t38HsDataRedundancy on a link prone to bursty loss during the high-speed image transfer phase reduces the chance a fax page fails to reassemble correctly at the receiving gateway.
