Connecting to the Alarm Port
The DB-15 alarm port on the switch’s front panel is used to provide alarm,
service port, and BITS clock reference interfaces. The switch supports two
sets of alarm relay contacts (major and minor), and 4 external customer
site alarm inputs. It also provides an alarm cutoff button (labeled ACO).
