units:

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.
Customer Administration Terminal (CAT)
The Customer Administration Terminal (CAT) is a digital multi-function telephone (Dterm)
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.
