IP Fax Configuration
2-4
received “1” is less than the preset threshold value, then the current rate train is
successful, otherwise, it is not successful.
Please perform the following configuration in dial peer configuration mode.
Table VC-2-4 Configure fax local-train threshold value
Operation Command
Configure fax local-train threshold value fax local-train threshold threshold
Restore the default value of fax local-train threshold value no fax local-train threshold
By default, the fax local-train threshold value is 10. The threshold value ranges from 0
to 100.
2.2.6 Configuring Gateway Carrier Transmit Energy Level
Generally, the default values of gateway carrier transmit energy level are acceptable. If
subscriber found fax could not established when the other configurations are correct,
you may try to adjust the gateway carrier transmit energy level. Less energy level value
shows higher energy.
Please perform the following configuration in dial peer configuration mode.
Table VC-2-5 Configure gateway carrier transmit energy level
Operation Command
Configure gateway carrier transmit energy level fax level level
Restore the default value of gateway carrier transmit energy level no fax level
By default, the gateway carrier transmit energy level is 15. The level value ranges from
3 to 60.
2.2.7 Configuring Sending Redundancy Packet Number of T38 Fax Protocol
Low-speed data indicates the command data compliant with V.21 and the data rate is
300bps. High-speed data indicates TCF and image data.
Please perform the following configuration in dial peer configuration mode.
Table VC-2-6 Configure sending redundancy packet number of T38 fax protocol
Operation Command
Configure redundancy packet number of low-speed data of
T38 fax protocol
fax protocol t38 ls-redundancy number
Restore the default value of redundancy packet number of
low-speed data of T38 fax protocol
no fax protocol t38 ls-redundancy
Configure redundancy packet number of high-speed data of
T38 fax protocol
fax protocol t38 hs-redundancy number
Restore the default value of redundancy packet number of
high-speed data of T38 fax protocol
no fax protocol t38 hs-redundancy
