| 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 via the t38ErrorCorrection object,
t38LsDataRedundancy has different meaning.
If FEC is disabled, then t38LsDataRedundancy is the
maximum number of prior IFP packets within an unnumbered
datagram protocol transport layer (UDPTL) packet carrying
low speed information, not counting the primary or current
IFP packet.
If FEC is enabled, then t38LsDataRedundancy is the maximum
number of FEC messages within a UDPTL packet carrying low
speed information. |
