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 U NIVERGE 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
