CHAPTER 7 TROUBLESHOOTING
##753 [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-NULL
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.
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 re-
transmissions was exceeded after transmission of PPS-NULL
The line condition is poor; as such, although PPR was received 4 times after trans-
mission of PPS-NULL and then CTC was transmitted, the other party could not
receive 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-NULL and then CTC was transmitted, no significant signal was
received correctly thereafter.
Ask the operator of the other party to increase the transmission level so that the
signal may be received correctly.
##755 [TX]
In ECM transmission, no significant signal can be received after
transmission of PPS-MPS, and the allowed number of procedure
signal re-transmissions was exceeded
The line condition is poor, and the other party cannot receive PPS-MPS correctly.
1. Increase the transmission level so that the other party may receive PPS-MPS
correctly.
2. Adjust the NL equalizer so that the other party may receive PPS-MPS correctly.
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.
