Code
0-52 Polarity changed during
communication
0-55 FCU (PCB2) does not detect the SG3.
0-56 The stored message data exceeds
the capacity of the mailbox in the
SG3.
0-70 The communication mode specified in
CM/JM was not available
(V.8 calling and called terminal)
0-74 The calling terminal fell back to T.30
mode, because it could not detect
ANSam after sending CI.
0-75 The called terminal fell back to T.30
mode, because it could not detect a
CM in response to ANSam (ANSam
timeout).
0-76 The calling terminal fell back to T.30
mode, because it could not detect a
JM in response to CM
(CM timeout).
0-77 The called terminal fell back to T.30
mode, because it could not detect a
CJ in response to JM
(JM timeout).
0-79 The called terminal detected CI while
waiting for a V.21 signal.
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
D0CK
Meaning Suggested Cause/Action
•
Check the line connection.
Retry communication.
•
FCU (PCB2) firmware or board defective.
•
SG3 firmware or board defective.
•
SG3 firmware or board defective.
•
The other terminal did not have a compatible
communication mode (e.g., the other terminal
was a V.34 data modem and not a fax modem.)
•
A polling TX file was not ready at the other
terminal when polling RX was initiated from the
calling terminal.
•
The calling terminal could not detect ANSam
due to noise, etc.
•
ANSam was too short to detect.
•
Check the line connection and condition.
•
Try making a call to another V.8/V.34 fax.
•
The terminal could not detect ANSam.
•
Check the line connection and condition.
•
Try receiving a call from another V.8/V.34 fax.
•
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.
•
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.
