Configure a fax training
mode
VoFR entities only support the PPP training mode.
When rate training is carried on between facsimile terminals, the transmitting
terminal transmits "zero-filled" TCF data (the filling time per packet is 1.5±10%
seconds) to the receiving facsimile terminal, and the receiving facsimile 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 again.
Configuration prerequisites
VoIP configuration is completed, IP calls can be made successfully, and fax
machines are connected correctly.
Configuration procedure
Follow these steps to configure a fax local training threshold:
To do...
Enter system view
Enter voice view
Enter voice dial program view
Enter voice entity view
Configure the fax training mode as
local training
Configure a fax local training
threshold
When the local training mode is adopted, use the fax local-train threshold
command to configure the threshold. When the PPP training mode is adopted, the
gateway does not participate in rate training and the fax local training threshold is
not applicable.
Usually, the default transmit energy level of the gateway carrier is acceptable. If
the fax cannot be set up yet on the condition that other configurations are correct,
you can attempt to adjust the transmit energy level of the gateway carrier.
