Code Meaning
The called terminal fell back to T.
30 mode, because it could not
0-77
detect a CJ in response to JM
(JM timeout).
The called terminal detected CI
0-79
while waiting for a V.21 signal.
The line was disconnected due to
0-80 a timeout in V.34 phase 2 – line
probing.
The line was disconnected due to
0-81 a timeout in V.34 phase 3 –
equalizer training.
The line was disconnected due to
0-82 a timeout in the V.34 phase 4 –
control channel start-up.
The line was disconnected due to
0-83 a timeout in the V.34 control
channel restart sequence.
The line was disconnected due to
0-84 abnormal signaling in V.34 phase
4 – control channel start-up.
The line was disconnected due to
0-85 abnormal signaling in V.34
control channel restart.
Suggested Cause/Action
• 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 main power switch, 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 main power switch, then turn it back
on.
• If the same error is frequent, replace the FCU.
