(2) Adjust the NL equalizer so that the other party may receive PPS-EOM
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.
##763 [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-EOM
Cause: The page buffer of the other party is full or is engaged; as such, although RNR
was received after transmission of PPS-EOM 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.
##764 [TX] In ECM transmission, the allowed number of procedure signal
retransmissions was exceeded after transmission of PPS-EOM
Cause: The line condition is poor; as such, although PPR was received 4 times after
transmission of PPS-EOM 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.
Cause: The line condition is poor; as such, although PPR was received 4 times after
transmission of PPS-EOM and then CTC was transmitted, no significant
signal was received correctly thereafter.
Remedy: Ask the operator of the other party to increase the transmission level so that
the signal may be received correctly.
##762 [TX] In ECM transmission, DCN was received after transmission of PPS-
EOM
