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.

Turn off the machine, then turn it back on.
• If the same error is frequent, replace the FCU.
0-86
