When connecting the RJ-45 port to a router, use the crossover cable pinout as shown in the below figure.

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. 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.
Figure 64: 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.
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.
Caution
To comply with the intrabuilding lightning surge requirements of Telecordia GR-1089-CORE, Issue II,
Revision 01, 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.
Note
This table lists the pin-to-signal correspondence between the cable connector pins and the alarm connector
relay contacts.
