gateway. The transmitting gateway finalizes the packet transmission rate by comparing the received
training result with its own training result.
• Point-to-point training—The gateways do not participate in the rate training between two fax
terminals. In this mode, rate training is performed between two fax terminals and is transparent to
the gateways.
Perform the following configuration in voice entity view.
Configuration prerequisites
VoIP configuration is completed, IP calls can be made successfully, and fax machines are connected
correctly.

oFR entities only support the PPP training mode.
Configuring threshold of local training
When rate training is carried on between fax terminals, the transmitting terminal transmits "zero-filled"
TCF data (the filling time per packet is 1.5±10% seconds) to the receiving fax terminal, and the receiving
fax terminal decides whether the current rate is acceptable according to the received TCF data.
When the percentage of all-ones or all-zeros TCF data to the total number of TCP data is less than the
local training threshold, the current rate training succeeds. Otherwise, the current rate training fails and
you need to drop the rate for a local training operation again.
