B.SYN1: is set to 'ON' when the relay is linked via multiplexer, and set to 'OFF' when direct link
is applied. (for channel 1)
This setting is available for CCITT G703-1.2.1, 1.2.2, 1.2.3, X21 and optical interface
(short distance: 2km class). In the case of optical interface 30km and 80km class, this
setting is neglected.
B.SYN2: same as above. (for channel 2)
Setting of RYID, RYID1 and RYID2
Relay address number RYID must take a different number at each terminal.
If the relay address monitoring switch [RYIDSV] is "OFF", their settings are ignored. The
RYID2 setting is enabled by setting the [TERM] to "3TERM" or "Dual".
Two-terminal application: Set the local relay address number to RYID and the remote relay
Three-terminal application: Set the local relay address number to RYID and the remote relay 1
Note: The remote 1 relay is connected by CH1 and the remote 2 relay connected by CH2

remote relay. See Figure 2.2.14.3.
In "Dual" setting, the RYID2 setting must be the same as the RYID1
setting.

RYID2. The RYID1 is equal to the RYID of the remote 1 relay and
the RYID2 equal to the RYID of the remote 2 relay. See Figure
