Code Meaning Suggested Cause/Action
0-77
The called terminal fell
back to T.30 mode,
because it could not
detect a CJ in response
to JM
(JM timeout).
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.
0-79
The called terminal
detected CI while waiting
for a V.21 signal.
Check for line noise or other line problems.
If this error occurs, the called terminal falls
back to T.30 mode.
0-80
The line was
disconnected due to a
timeout in V.34 phase 2 –
line probing.
The guard timer expired while starting these
phases. Serious noise, narrow bandwidth, or low
signal level can cause these errors.
If these errors happen at the transmitting
terminal:
Try making a call at a later time.
Try using V.17 or a slower modem using
dedicated tx parameters.
Try increasing the tx level.
Try adjusting the tx cable equalizer setting.
If these errors happen at the receiving
terminal:
Try adjusting the rx cable equalizer setting.
Try increasing the tx level.
Try using V.17 or a slower modem if the same
error is frequent when receiving from multiple
senders.
0-81
The line was
disconnected due to a
timeout in V.34 phase 3 –
equalizer training.
0-82
The line was
disconnected due to a
timeout in the V.34 phase
4 – control channel
start-up.
0-83
The line was
disconnected due to a
timeout in the V.34
control channel restart
sequence.
