Panel, the other connecting CCU B to the
RS-232 Switch Panel.
For D200 systems, two cable assemblies
are required, one connecting CCU A to the
RS-232 Switch Panel, the other
connecting CCU B to the RS-232 Switch
Panel.
Connects CCU A to CCU B, when a ping
connection is used for communication
between the two CCUs.
HDLC Cable Connects CCU A to CCU B, when a D.20
