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 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.
Customer Administration Terminal (CAT)
The Customer Administration Terminal (CAT) is a digital multi-function telephone (D
term
) which is
equipped with function keys, a dial pad and LCD and interfaces with the system via the MP card.
Programming of the system can be done from selected Multiline Terminals with LCD. The
designated Multiline Terminals can be placed in program mode, and system data can then be
changed. To prevent unauthorized changes, password levels are assigned, providing authorization for
access to certain areas of programming and denying access to others.
Service Conditions
1. Programming from a Customer Administration Terminal can only be accomplished when the
system is online.
2. All Multiline Terminals with LCD scanned during initialization will be Customer
Administration Terminals.
3. The commands CM00 (Office Data All Clear) and CM01 (Office Data Partial Clear) cannot
be accessed from the CAT. The CAT cannot delete itself from the system program.
4. Only two Customer Administration Terminals can be in program mode at the same time.
5. The data that can be changed from the CAT can be limited by the Password level assigned.
There are eight levels of Passwords that can be assigned in system programming. The relation
between Password level and access to available commands is also assigned in system
programming.
6. A password can consist of a maximum of any eight digits with the following limitation: The
password cannot be CCCCCCCC or FFFFFFFF.
7. Caution should be exercised when assigning Passwords to command authorization levels. If a
password is forgotten, access to system programming will be limited and a system
initialization with subsequent programming may be required.
8. When the Customer Administration Terminal is offline for programming, it cannot access
normal terminal functions.
