Vertical Communications DSU and DSU II - Manual (Page 40)

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.
•
To display alarm codes,
1. Press and hold ✳ for 5 seconds. The following status reports will
be displayed:
— Station disconnected from station port for more than five minutes.
Month, day, station port number, and station extension number are
shown.

— Data printer off-line.

You may press 0 to cancel the alarm report displays.
After the information has been shown on the display, the ✳ disappears
until another alarm occurs.
