CHAPTER 8. USING THE CONSOLE
TO TROUBLESHOOT THE SYSTEM
The attendant console provides access to several features and facilities that can be used to
troubleshoot system problems. This chapter presents some procedures and suggestions for
isolating and analyzing troubles before calling for higher-level maintenance.
Trouble Reporting
Each system site should have a well-defined policy for collecting and responding to system
alarms and user-generated trouble reports. System-alarmed troubles produce visible signals
at the attendant console(s) and at selected voice terminals as well as on the system
equipment cabinet.
If the system has a link to a remote maintenance center, alarms are sent to that location
automatically. Otherwise, system-alarmed troubles must be reported immediately to the
System Manager, who is responsible for clearing them or calling a designated maintenance
organization.
Troubles detected by system users must be reported

Alarm/Alarm Reported (Enhanced) and Alm-Ack (Basic) Lamps
The basic alarm indicator of the attendant console is the Alm-Ack pair of lamps to the left of
the touch-tone dial on the Basic Console (Figure 2-8) and the Alarm and Alarm Reported
lamps to the right of the touch-tone dial on the Enhanced Console (Figure 2-9). The Alarm
and Alm lamps light when a system trouble is detected and remains lighted until the trouble
is cleared. If the system has the remote maintenance option, the Alarm Reported and
adjacent Ack lamps soon light steadily, showing that the maintenance center has been
automatically alerted. At this point, the center assumes responsibility for clearing the trouble.
An Alarm Reported or Ack lamp that flashes for any extended length of time after the Alarm
or Alm lamp lights means that the system is unable to notify the maintenance center. You,
the attendant, must alert the System Manager to the unresolved alarm condition.
