Alarm Relay

Previous releases of the DEFINITY AUDIX system could use the two-wire alarm relay to notify INADS of major alarms. Although the DEFINTY AUDIX system can notify INADS of minor alarms via the external modem, the system will no longer use the two-wire alarm relay to signal minor alarms.

For more information about Alarm Origination for DEFINITY AUDIX system Release 4.0, including self-diagnostics, the external modem, and the alarm relay, see Chapter 3.

LEDs

DEFINITY AUDIX system Release 4.0 uses three light-emitting diodes (LEDs) on its faceplate to display system status and health. Previous system releases used a liquid crystal display (LCD) for the same purpose. The LCD used three maintenance buttons and a structured set of menus to display messages about system status.

The LEDs on Release 4.0 display information similar to the messages on the old LCD. However, technicians and system administrators cannot manipulate the LEDs to display different types of messages while the system is running.

NOTE:

The two recessed maintenance buttons on DEFINTY AUDIX system Release 4.0 do not perform the same functions as the three maintenance buttons for the LCD on previous system releases. For more information about the LEDs and recessed maintenance buttons on Release 4.0, see Chapter 3.

MO Disk Drive

DEFINITY AUDIX system Release 4.0 uses a magneto-optical (MO) disk drive for backups and software upgrades. Previous releases used a tape drive.

The MO disk drive is smaller than the tape drive, which helps reduce the system’s demand for space in the customer’s switch. The rewritable disks for the MO disk drive offer slightly more storage space than the tapes for the tape drive, as well as flexibility for data access and reuse. For more information about the MO disk drive, see Chapter 2, Chapter 3, and Chapter 3.
