ERROR CODES
SM 4-5 B465
Fax Unit
B465
Code Meaning Suggested Cause/Action
0-74 The calling terminal fell back
to T.30 mode, because it
could not detect ANSam
after sending CI.
• 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.
0-75 The called terminal fell back
to T.30 mode, because it
could not detect a CM in
response to ANSam
(ANSam timeout).
• The terminal could not detect ANSam.
• Check the line connection and condition.
• Try receiving a call from another V.8/V.34 fax.
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).
• 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.
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.
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.
• 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.
0-84 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 machine, then turn it back on.
• If the same error is frequent, replace the FCU.
0-85 The line was disconnected
due to abnormal signaling in
V.34 control channel restart.
• 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.
