Alarm subconnectors can be used to connect the router to an external site alarm
maintenance system. Any critical, major, and minor alarms generated by the
router also energize alarm relays on the alarm card and activate the external site
alarm. The alarm relay contacts on the alarm card consist of standard common,
normally open, and normally closed relay contacts that are wired to the alarm
connector pins.
Table 2-13 lists the pin-to-signal correspondence between the connector pins and
the alarm card relay contacts. Because alarm contact cables are entirely dependent
on installation site circumstances, alarm connector cables are not available from
Cisco. For information about alarm connector wiring requirements and the
pinouts for the alarm connector interface, see the
