OVERVIEW OF INSTALLATION, PROGRAMMING, AND MAINTENANCE

System Data Entry

There are two methods for data entry, using a Customer Administration Terminal (CAT) or a Maintenance Administration Terminal (MAT).

CAT

Any Dterm can be assigned as a CAT through programming. The Dterm can still be used as a regular telephone when it is not in CAT mode.

MAT

The Maintenance Administration Terminal (MAT) is a personal computer that connects to the PBX using MATWorX software. MATWorX is a Windows-based software application that lets you program and configure any NEAX PBX from your computer. It is a framework or platform wherein PBX maintenance software (add-ins) resides. Its graphical user interface (GUI) makes it easier for you to manage and configure your PBX's features.

Maintenance

Trouble Reporting and Diagnosis

The urgency of a fault is indicated by the MJ/MN lamp provided on the Power Card and optional external alarm indicator.

System Administration

System data, which varies from installation to installation and which is subject to continual change during service, is readily entered or changed from the Dterm or MAT (Maintenance Administration Terminal).

The system data can be downloaded to, or uploaded from, a floppy disk in the MAT computer.

Remote Maintenance

Access to the NEAX 2000 IPS, for the purpose of system diagnosis, status reporting, and database reconfiguration, can be performed from remote locations (e.g., Maintenance Centers, Technical Assistance Service Centers, etc.). By taking advantage of the built-in modem on the NEAX 2000 IPS CPU, the following maintenance administration functions can be accomplished by a remotely located MAT via a modem over a central office network or a tie line network.
