Parameter Reference
Broken Fax V.21 Preamble
Description: The gateway supports a mode such that when the incoming signal contains V.21
preamble, silence, V.21 preamble then the Media Gateway will remove silence and send one V.21
preamble not two.
Note: The broken fax V.21 setting is currently only supported on the DMG2030DTIQ and
DMG2060DTISQV34.
Allowed Values:
• On
• Off
Default Value = Off
INI File Parameter Name = dspFaxSendOneV21PreambleEnable
V.34 Fax Retrain Enable
Description: The gateway supports a mode that enables automatic rate reduction when line
impairments are present. Reducing the fax rate will reduce fax retransmissions (PPRs). In the case
where multiple PPRs occur, the gateway will issue a retrain command and lower the rate. For
example, by default, the gateway will retrain to two rates lower (Fax Retrain Step Down=2) after
two block PPRs (Fax Retrain Threshold=2).
Note: The V.34 fax retrain enable setting is currently only supported on the DMG2030DTIQ and
DMG2060DTISQV34.
Allowed Values:
• On
• Off
Default Value = On
INI File Parameter Name = dspFaxV34RetrainEnable
V.34 Fax Retrain Threshold
Description: This parameter sets the number of PPRs (retransmissions) threshold to enable retrain
to a lower rate.
Note: The V.34 retrain threshold setting is currently only supported on the DMG2030DTIQ and
DMG2060DTISQV34.
Allowed Values: 1 to 4
Default Value = 2
INI File Parameter Name = dspFaxV34RetrainThreshold
