RCC Standby LED States
The Standby LED on the RCC indicates that software is loaded on the card and is ready to provide a path for data or
signalling traffic from a line card to a redundant PAC/PSC. This LED should be on for normal operation for both RCCs
installed.

Testing System Alarm Outputs
The system provides the following two physical alarm mechanisms:
System Audible Alarm: Located on the SPC/SMC, the speaker is used to provide an audible indicator that a
minor, major, or critical alarm has occurred.
CO Alarms Interface: Located on the SPIO, this interface provides a 10-pin connector that enables three
normally-closed dry-contact relays for the triggering of external audio and/or visual indicators. These
indicators can be used to alert that either a minor, major, or critical alarm has occurred.
