8.6.1 Telco Alarm Cutoff Push Button
The SAM provides a Telco alarm cutoff function with the front-panel push button switch
located on the ADP. This push button activates the alarm cutoff (ACO) state. When ACO is
activated, the active alarm LED blinks and all of the alarm relays are deactivated. This button
does not clear alarms. Refer to Figure 8-2 on page 175 for the location of the alarm cutoff push
button switch.
8.6.2 Telco Alarm LEDs
These LEDs are used to indicate the presence of the critical, major, and minor alarms. When a
LED is lit, the respective alarm is active. A blinking LED signals an alarm cut-off state which is
initiated by pressing the alarm cut-off button when an alarm is active.
8.6.3 Telco Alarm Interface
The SAM provides a front-panel alarm connector, which is a standard DB-15 connector with the
following pin assignments:
