Translating the fax trace report
Print a fax log report (see the user guide for instructions). The fax log
report contains information about the product’s interpretation of the
problem.
Read the time sequences, looking for abnormal activity on the fax
trace report. See table 24, “Fax phase sequence,” on page 223, and
table 25, “Appropriate responses,” on page 224, to separate normal
from abnormal activity. Fax abbreviations appear in table 26 on page
225.
Identify the phase in which the error occurred.
Note ??? is an unidentified command.
Examples of a successfully sent fax and a successfully received fax
appear after the tables.
431 The transmitting machine has not
received a response after aborting a
transmission. Depending upon when the
session is aborted, some remote
machines may not respond. It should be
noted that the local unit always attempts
to abort the session in such a way that
the remote machine is allowed to
respond to the final PPS_EOP.
No action required. The session was
aborted.
440-444 Error occurred during a V.34
transmission after one or more partial
pages (image data) were transmitted
using the primary channel. The
transmitting machine was unable to
restart the control channel in order to
resume the T.30 handshake. This
typically occurs when the receiving
machine prematurely disconnects during
partial page reception, although it is
possible it may also be caused by
compatibility issues.
Reattempt the fax reception at a different
time when telephone line conditions
have improved.
