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 to some central position such as an attendant or the System Manager, who either resolves the troubles or requests help from a remote maintenance center.

Console Alarm Indicators

The console has built-in alarm lamps that indicate major or minor troubles in the system switch. In addition, feature button lamps on the console can be administered as alarm indicators for more specific conditions.

Alarm/Alarm Reported (Enhanced) and Alm-Ack (Basic) Lamps

The basic alarm indicator of the attendant console is the Alm-Ackpair 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 a n d 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.
