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.
