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.
0-84 The line was disconnected
due to abnormal signaling in
V.34 phase 4 – control
channel start-up.
 The signal did not stop within 10 s.
 Turn off the main power switch, then turn it
back on.
 If the same error is frequent, replace the
FCU.
