Connecting an External Alarm Monitoring Facility
The clock and scheduler card (CSC) incorporates a 25-pin D-sub connector on the card
faceplate (see Figure 3-16) that enables you to attach a site-wide external alarm monitoring
facility to the Cisco 12008. This facility is described in Chapter 1 in the section entitled
"Housekeeping and Alarm Monitoring Functions of the CSC."
