Adjust the NL equalizer so that the other party may receiveEOR-EOP correctly.3. Add an echo protect tone to the V.29 modem signal fortransmission.Cause: The line condition is poor, and the significant signal cannot bereceived correctly.Remedy: Ask the operator of the other party to increase the transmissionlevel so that the signal may be received correctly.##787 [TX] In ECM transmission, DCN was received aftertransmission of EOR-EOPCause: The line condition is poor, and the other party cannot receiveEOR-EOP correctly.Remedy: 1. Increase the transmission level so that the other party mayreceive EOR-EOP correctly.2. Adjust the NL equalizer so that the other party may receiveEOR-EOP correctly.3. Add an echo protect tone to the V.29 modem signal fortransmission.Cause: The Stop key was pressed during a communication.Remedy: Transmit once again.##788 [TX] In ECM transmission, the allowed number of proceduresignal retransmissions was exceeded or a T5 time-over(60 sec) condition occurred after transmission of EOR-EOPCause: The page buffer of the other party is full or is engaged; as such,although RNR was received after transmission of EOR-EOP andthen RR was transmitted, no significant signal was receivedcorrectly thereafter.##785 [TX] In ECM transmission, no significant signal can bereceived after transmission of EOR-EOP, and theallowed number of procedure signal re-transmissionswas exceeded
