RSP and RP Port Connection Guidelines
Alarm Connection Guidelines
The RSP/RP card has an alarm connector on its front panel. This 9-pin D-subconnectors (ALARM OUT)
connects the router to an external site alarm maintenance system (Figure 1-65). When a critical, major,
or minor alarm is generated, it energizes the alarm relays on the RSP/RP card to activate the external site
alarm.
Figure1-65 Alarm Connector on the RSP/RP Card Front Panel
The alarm relay contacts on the RSP/RP card consist of standard common, normally open, and normally
closed relay contacts that are wired to the pins on the connectors.
Caution Only safety extra-low voltage (SELV) circuits can be connected to the alarm connector. Maximum rating
for the alarm circuit is 100 mA, 50 V.
Note To comply with the intrabuilding lightning surge requirements of Telecordia GR-1089-CORE, IssueII,
Revision01, February 1999, you must use a shielded cable when connecting to the external alarm port
on the RSP/RP card. The shielded cable is terminated by shielded connectors on both ends, with the
cable shield material tied to both connectors.
