Code Meaning
The called terminal detected
0-79 CI while waiting for a V.21
signal.
The line was disconnected due
0-80 to a timeout in V.34 phase 2 –
line probing.
The line was disconnected due
0-81 to a timeout in V.34 phase 3 –
equalizer training.
The line was disconnected due
0-82 to a timeout in the V.34 phase
4 – control channel start-up.
The line was disconnected due
0-83 to a timeout in the V.34 control
channel restart sequence.
The line was disconnected due
to abnormal signaling in V.34
0-84
phase 4 – control channel
start-up.
The line was disconnected due
0-85 to abnormal signaling in V.34
control channel restart.
The line was disconnected
because the other terminal
requested a data rate using
0-86
MPh that was not available in
the currently selected symbol
rate.
Suggested Cause/Action
• 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.
• If the same error is frequent, replace the FCU.
• The other terminal was incompatible.
• Ask the other party to contact the manufacturer.
