4.2.3.2 Detailed Discussions of Bit 1
Use it to enable/disable transmission of an echo protect tone for a high-speed transmission
V.29 modem signal (transmission speed at 9600 or 7200 bps).
If errors occur frequently at time of transmission because of the condition of the line, select
'transmit' so that a non-modulation carrier will be transmitted as a pre-image transmission
sync signal for about 200 msec.
Memo: Any of the following error codes may be indicated because of the line condition at
time of transmission
