<Remarks>
FUNC 5 Bits 7 and 6:
These bits program the equalizer value which has frequency characteristics. For
long-distance communication, a larger equalizer value is recommended as a rule.
FUNC 5 Bit 5:
This bit selects whether or not the echo protect tone is added before the training for
V.29 (9600 bps) communication. By adding the echo protect tone, the echo cancel
circuit of the satellite line is started up to improve the line status.
FUNC 5 Bit 4:
This bit selects whether or not a delay (500 ms) is inserted before sending the signal
at reversing transmission/reception change and the timing is shifted to avoid line
echo.
When the echo preventing circuit or echo cancel circuit causes missing of the begin-
ning of the signal, for example, in overseas communications where a delay may be
larger, this bit should be set to 1 (on).
FUNC 5 Bit 3:
This bit selects whether or not a delay (500 ms) is inserted before the high-speed
signal is sent to shift the timing. Explanation for bit 4 is applicable.
FUNC 5 Bit 1:
This bit selects whether or not the CNG signal is output in manual transmission (on-
hook dialing/off-hook dialing). When the receiving terminal uses a switching device,
CNG signal output is required (1=on).
FUNC 5 Bit 0:
This bit selects whether or not the CED signal is transmitted in manual reception.
