2.11 System Alarm Reporting

Occasionally, the DSU system will fail to communicate with a particular station; it could be that the station has been disconnected from its station port or that the system printer is off line. When the system experiences these disruptions, an alarm signal will display at the attendant’s station or any LCD speakerphone when enabled by class of service programming. In order to review the system alarms, the attendant can command the system to present alarm codes on the station display.

When this feature is provided, a flashing appears on the first line of your telephone’s LCD to indicate that new alarms are present. It is a good idea to write down which alarms are displayed so that you may report the nature of the alarms to your system installer.
