Code Meaning
0-75 The called terminal fell
back to T.30 mode,
because it could not detect
a CM in response to
ANSam (ANSam timeout).
0-76 The calling terminal fell
back to T.30 mode,
because it could not detect
a JM in response to a CM
(CM timeout).
0-77 The called terminal fell
back to T.30 mode,
because it could not detect
a CJ in response to JM
(JM timeout).
0-79 The called terminal
detected CI while waiting
for a V.21 signal.
0-80 The line was disconnected
due to a timeout in V.34
phase 2 – line probing.
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.
0-85 The line was disconnected
due to abnormal signaling
in V.34 control channel
restart.
0-86 The line was disconnected
because the other terminal
requested a data rate
using MPh that was not
available in the currently
selected symbol rate.

Suggested Cause/Action
• 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.
If this error occurs, the called terminal falls back
to T.30 mode.
• 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.
• The signal did not stop within 10 s.
• Turn off the machine, then turn it back on.
• If the same error is frequent, replace the FCU.
• The signal did not stop within 10 s.
• Turn off the machine, then turn it back on.
• If the same error is frequent, replace the FCU.
• The other terminal was incompatible.
• Ask the other party to contact the
manufacturer.
