sending CI.
 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 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.
 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.
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 main power switch, then turn it back on.
