Table 6-57: Fax and Modem Parameters
Fax transport mode used by the device.
[0] Disable = transparent mode.
[1] T.38 Relay = (default).
[2] Bypass.
[3] Events Only.
Note: This parameter is overridden by the parameter IsFaxUsed.
If the parameter IsFaxUsed is set to 1 (T.38 Relay) or 3 (Fax
Fallback), then FaxTransportMode is always set to 1 (T.38 relay).
Determines the V.34 fax transport method (whether V34 fax falls
back to T.30 or pass over Bypass).
[0] = Transparent
[1] = Relay (default)
[2] = Bypass
[3] = Transparent with Events
Note: To configure V34FaxTransportType to 1 (i.e., fax relay),
you also need to configure FaxTransportMode to 1 (fax relay).
Number of times that control packets are retransmitted when
using the T.38 standard.
The valid range is 0 to 4. The default value is 0.
Number of times that each fax relay payload is retransmitted to
the network.
[0] = No redundancy (default).
[1] = One packet redundancy.
[2] = Two packet redundancy.
Note: This parameter is applicable only to non-V.21 packets.
Maximum rate (in bps), at which fax relay messages are
transmitted (outgoing calls).
[0] 2400 = 2.4 kbps.
[1] 4800 = 4.8 kbps.
[2] 7200 = 7.2 kbps.
[3] 9600 = 9.6 kbps.
[4] 12000 = 12.0 kbps.
[5] 14400 = 14.4 kbps (default).
Note: The rate is negotiated between the sides (i.e., the device
adapts to the capabilities of the remote side).
