SM 25 D0CK
Code Meaning Suggested Cause/Action
timeout in V.34 phase 3 – equalizer
training.
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.
0-82 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.
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
(PCB2).
0-85 The line was disconnected due to
abnormal signaling in V.34 control
channel restart.
•
