Code
after sending CI.
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 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
Meaning
Suggested Cause/Action
•
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.
•
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.
