 Bypass mechanism for V.34 fax transmission (see ''Bypass Mechanism for V.34 Fax
Transmission'' on page

 T.38 Version 0 relay mode, i.e., fallback to T.38 (see ''Relay Mode for T.30 and V.34
Faxes'' on page

Note:
• The CNG detector is disabled in all the subsequent examples. To disable the CNG
detector, set the 'CNG Detector Mode' parameter (CNGDetectorMode) to Disable.
14.2.3.1 Bypass Mechanism for V.34 Fax Transmission
In this proprietary scenario, the device uses bypass (or NSE) mode to transmit V.34 faxes,
enabling the full utilization of its speed.
 To use bypass mode for T.30 and V.34 faxes:
1. On the Fax/Modem/CID Settings page, do the following:
a. Set the 'Fax Transport Mode' parameter to Bypass (FaxTransportMode = 2).
b. Set the 'V.22 Modem Transport Type' parameter to Enable Bypass
(V22ModemTransportType = 2).
c. Set the 'V.23 Modem Transport Type' parameter to Enable Bypass
(V23ModemTransportType = 2).
d. Set the 'V.32 Modem Transport Type' parameter to Enable Bypass
(V32ModemTransportType = 2).
e. Set the 'V.34 Modem Transport Type' parameter to Enable Bypass
(V34ModemTransportType = 2).
 To use bypass mode for V.34 faxes, and T.38 for T.30 faxes:
1. On the Fax/Modem/CID Settings page, do the following:
a. Set the 'Fax Transport Mode' parameter to T.38 Relay (FaxTransportMode = 1).
b. Set the 'V.22 Modem Transport Type' parameter to Enable Bypass
(V22ModemTransportType = 2).
c. Set the 'V.23 Modem Transport Type' parameter to Enable Bypass
(V23ModemTransportType = 2).
d. Set the 'V.32 Modem Transport Type' parameter to Enable Bypass
(V32ModemTransportType = 2).
e. Set the 'V.34 Modem Transport Type' parameter to Enable Bypass
(V34ModemTransportType = 2).
14.2.3.2 Relay Mode for T.30 and V.34 Faxes
In this scenario, V.34 fax machines are forced to use their backward compatibility with T.30
faxes and operate in the slower T.30 mode.
 To use T.38 mode for V.34 and T.30 faxes:
1. On the Fax/Modem/CID Settings page, do the following:
a. Set the 'Fax Transport Mode' parameter to T.38 Relay (FaxTransportMode = 1).
b. Set the 'V.22 Modem Transport Type' parameter to Disable
(V22ModemTransportType = 0).
c. Set the 'V.23 Modem Transport Type' parameter to Disable
(V23ModemTransportType = 0).
