Panel
The Dry Contact (DRYC) card provides the following functions:
 Support 8 ways of on/off value output control and 8 ways of on/off
value input detection.
 Support 2 on/off value transmission modes. In shared timeslot mode, 8
ways of dry contact input detection or output control share TS0. In
independent timeslot mode, each way of dry contact input detection or
output control occupies a timeslot, so 8 ways occupy TS0–TS7.
 Dry contact input occupies TS0–TS7 of No.1 E1 in uplink bus of the
backplane, and dry contact output occupies TS0–TS7 of No.1 E1 in
downlink bus.
 Dry contact input supports three control sources: peer input control,
network management control, and local input control.

The input detection interface adopts an isolated power scheme to avoid
impact on system power.
 Lightning protection level: 4 kV in common mode and 2 kV in
differential mode.
