CHAPTER 7 TROUBLESHOOTING
##775 [TX]
In ECM transmission, no significant signal can be received after
transmission of EOR-MPS, and the allowed number of procedure
signal re-transmissions was exceeded
The line condition is poor, and the other party cannot receive EOR-MPS cor-
rectly.
1. Increase the transmission level so that the other party may receive EOR-MPS
correctly.
2 . Adjust the NL equalizer so that the other party may receive EOR-MPS 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 cor-
rectly.
Ask the operator of the other party to increase the transmission level so that
the signal may be received correctly.
##777 [TX]
In ECM transmission, DCN was received after transmission of
EOR-MPS
The line condition is poor, and the other party cannot receive EOR-MPS cor-
rectly.
1. Increase the transmission level so that the other party may receive EOR-MPS
correctly.
2 . Adjust the NL equalizer so that the other party may receive EOR-MPS cor-
rectly.
3 . Add an echo protect tone to the V.29 modem signal for transmission.
The Stop key was pressed during a communication.
Transmit once again.
##778 [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 EOR-MPS
The page buffer of the other party is full or is engaged; as such, although
RNR was received after transmission of EOR-MPS and then RR was transmit-
ted, 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.
