Introduction

Automatic Tests

The system performs ongoing maintenance automatically by running tests that:
Monitor the status of equipment.
Audit operations consistency.
Detect hardware malfunctions.
Without disrupting normal service, the tests check hardware and software that
are in service. The system registers any errors it detects in the error logs and, if
possible, corrects them automatically.
Alarms
If the automatic tests indicate serious error conditions, the system generates an
alarm. Depending on how the system is programmed, the system announces an
alarm condition in one of the following ways:
An LED for a line or feature button turns on at an operator console or
other designated telephone.
The red status LED on the processor module lights.
In Release 3.0 and later, the error code/status display on the processor
module displays
Restarts''
(Restart).
If a software installation or upgrade is taking place, a blinking character is
displayed to indicate the status of the procedure. See

information.
The status display indicates an alarm (on an MLX-20L console or a PC
running SPM), and can be viewed on the Error screen.
A supplemental alert, bell, chime, or strobe, if installed, is activated.
