##752 [TX]
In ECM transmission, DCN was received after
transmission of PPS-NULL
Cause:
The line condition is poor, and the other party cannot receive PPS-
NULL correctly.
Remedy:
1. Increase the transmission level so that the other party may
receive PPS-NULL correctly.
2. Adjust the NL equalizer so that the other party may receive
PPS-NULL correctly.
3. Add an echo protect tone to the V.29 modem signal for
transmission.
Cause:
The Stop key was pressed during a communication.
Remedy:
Transmit once again.
##753 [TX]
In ECM transmission, the allowed number of
procedure signal retransmissions was exceeded or a T5
time-over (60 sec) condition occurred after
transmission of PPS-NULL
Cause:
The page buffer of the other party is full or is engaged; as such,
although RNR was received after transmission of PPS-NULL and
then RR was transmitted, no significant signal was received
correctly thereafter.
Remedy:
1. Start G3 mode, and transmit once again (Prohibit the ECM
mode).
2. Decrease the transmission start speed.
3. Record the protocol on a DAT or MD, and have it analyzed by
the local Canon office and/or Technical Center.
##754 [TX]
In ECM transmission, the allowed number of procedure
signal retransmissions was exceeded after transmission
of PPS-NULL
Cause:
The line condition is poor; as such, although PPR was received 4
times after transmission of PPS-NULL and then CTC was
transmitted, the other party could not receive it correctly.
Remedy:
Increase the transmission level so that the other party may receive
CTC correctly.
