CHAPTER 7 TROUBLESHOOTING
##768 [TX]
In ECM transmission, the allowed number of procedure signal re-
transmissions was exceeded or a T5 time-over (60 sec) condition
occurred after transmission of PPS-EOP
The page buffer of the other party is full or is engaged; as such, although RNR
was received after transmission of PPS-EOP and then RR was transmitted, no sig-
nificant signal was received correctly thereafter.
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.
##769 [TX]
In ECM transmission, the allowed number of procedure signal re-
transmissions was exceeded after transmission of PPS-EOP
The line condition is poor; as such, although PPR was received 4 times after trans-
mission of PPS-EOP and then CTC was transmitted, the other party could not re-
ceive it correctly.
Increase the transmission level so that the other party may receive CTC correctly.
The line condition is poor; as such, although PPR was received 4 times after trans-
mission of PPS-EOP and then CTC was transmitted, no significant signal was re-
ceived correctly thereafter.
Ask the operator of the other party to increase the transmission level so that the
signal may be received correctly.
##770 [TX]
In ECM transmission, no significant signal can be received after
transmission of EOR-NULL, and the allowed number of procedure
signal re-transmissions was exceeded
The line condition is poor, and the other party cannot receive EOR-NULL cor-
rectly.
1. Increase the transmission level so that the other party may receive EOR-NULL
correctly.
2. Adjust the NL equalizer so that the other party may receive EOR-NULL cor-
rectly.
3. Add an echo protect tone to the V.29 modem signal for transmission.
The line condition is poor, and the significant signal cannot be received correctly.
Ask the operator of the other party to increase the transmission level so that the
signal may be received correctly.
