NEC 2000 IPS manual System Diagnostics, Self Diagnostic/System Messages, Remote Maintenance

Chapter 8 System Administration

System Diagnostics

When a fault occurs in the system, an audible and visual indication will be given at the following units:

External alarm indicating unit

Fault messages reported at MATWorX for remote reporting

Alarm lamps in front of each package mounted in the frame

Self Diagnostic/System Messages

The UNIVERGE NEAX 2000 IPS provides a sophisticated array of self-diagnostic routines that are continually and automatically being performed. Various system messages are printed when a fault occurs in a central processor system, switch network processors. Many other miscellaneous system messages and change of key status messages are also printed.

Remote Maintenance

This feature allows station and trunk changes or reassignments to be performed without a site visit by service personnel, and can be used to retrieve fault codes prior to visiting a site. One Remote Maintenance center can service an unlimited amount of systems, thus reducing the amount of personnel to maintain each site, travel costs and customer billing for each site.

Service Conditions

1. The following additional equipment is required for this feature:

A modem at the maintenance center and one at each remote site. (When the internal modem of the Main Processor (MP) is used, no modem at each remote site is required)

A cable for connection between the MP and the on-site modem. (When the internal modem of the MP is used, the above cable is not required)

2. The internal modem of the MP is compatible with the following specifications:

	Modem Specification
	ITU-T V.22 1200 bps	ITU-T V.32	4800/9600 bps
	ITU-T V.22 bis 2400 bps	ITU-T V.34	19.2 k/33.6 kbps
	Bell 212A 1200 bps
3. Any one of the following connections are also required for access to the modem:
	Required Connection
	A dedicated line		Attendant controlled transfer
	Direct Inward System Access (DISA)		Direct Inward Termination

4. The following operations can be executed from the Remote Maintenance location:

Retrieval of fault data

Retrieval of Peg Count information

Deletion or addition of system data (line, trunk, etc.) using a preprogrammed security password Data assignment by device number (stations, trunks, and Attendant Console)

Copying of station data from one station to other stations (when adding sequential stations in groups) Release / Reconnection of backup batteries

Display of station line status
