ERROR CODES
B750 22 SM
Code Meaning Suggested Cause/Action
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.
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.
• The other terminal was incompatible.
•
Ask the other party to contact the manufacturer.
0-87 The control channel started
after an unsuccessful
primary channel. •
The receiving terminal restarted the control
channel because data reception in the primary
channel was not successful.
• This does not result in an error communication.
0-88
The line was disconnected
because PPR was
transmitted/received 9
(default) times within the
same ECM frame. • Try using a lower data rate at the start.
•
Try adjusting the cable equalizer setting.
