[Bit 1]
Use it to specify whether or not to transmit an echo protection tone for high-speed transmission V.29 (9600 or 7200
bps; modem signal).
If an error occurs often because of a line condition at time of transmission, set it to '1'. If set to '1', unmodulated carrier
will be transmitted as a sync signal before transmission of an image for about 200 msec.
MEMO:
The following error codes are associated with a line condition at time of transmission:
##100, ##104, ##281, ##282, ##283, ##750, ##755, ##760, ##765
[Bit 7]
Use it to specify whether or not to transmit a 1080-Hz tonal signal before transmission of the CED signal. Set it to
'1' if an error occurs often because of an error at time of reception.
MEMO:
The following error codes are associated with an echo at time of reception:
##005, ##101, ##106, ##107, ##114, ##200, ##201, ##790
[Bit 4, 5, 6]
