Function
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.
Support online software upgrade, and support querying SN.
