cxeCallCtrlT38LsRedundancy
Module: CISCO-XGCP-EXT-MIB
OID (symbolic): CISCO-XGCP-EXT-MIB::cxeCallCtrlT38LsRedundancy
OID (numeric): 1.3.6.1.4.1.9.9.325.1.1.1.1.15
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description: This object determines the extent of the Internet Fax Protocol (IFP) packet transmission redundancy for the low-speed control information exchanged during the first phase of a T.38 fax relay connection.
Depending on whether Forward Error Correction (FEC) is enabled (cxeCallCtrlT38FecEnabled is set to 'true') or not, this object has different meanings. If FEC is disabled, then this object is the maximum number of prior IFP packets within a Unnumbered Datagram Protocol Transport Layer (UDPTL) packet carrying low speed information, not counting the primary or current IFP packet.
If FEC is enabled, then this object is the maximum number of FEC messages within a UDPTL packet carrying low speed information.
This object is not applicable if cxeCallCtrlT38Inhibited is set to 'true'.
What is cxeCallCtrlT38LsRedundancy?
This read-write Integer32 (0-5) sets the amount of low-speed IFP packet retransmission redundancy used during the initial control-information phase of a T.38 fax relay call, with its exact meaning depending on whether Forward Error Correction is enabled. Admins tune it to trade bandwidth for resilience against packet loss during fax call setup on the network. For example, on a link with occasional packet loss, an admin might raise this from 0 toward 5 to make the low-speed T.38 handshake more tolerant of dropped packets.
