Suggested Cause/Action
The other terminal did not have a compatible
communication mode (e.g., the other terminal
was a V.34 data modem and not a fax
modem.)
A polling tx file was not ready at the other
terminal when polling rx was initiated from the
calling terminal.
The calling terminal could not detect ANSam
due to noise, etc.
ANSam was too short to detect.
Check the line connection and condition.
Try making a call to another V.8/V.34 fax.
The terminal could not detect ANSam.
Check the line connection and condition.
Try receiving a call from another V.8/V.34 fax.
The called terminal could not detect a CM due
to noise, etc.
Check the line connection and condition.
Try making a call to another V.8/V.34 fax.
The calling terminal could not detect a JM due
to noise, etc.
A network that has narrow bandwidth cannot
pass JM to the other end.
Check the line connection and condition.
Try receiving a call from another V.8/V.34 fax.
Check for line noise or other line problems.
