11.5 Access levels
Access levels are entered as part of the login process, allowing different users to
access different functions. The six access levels are numbered 5 to 0, with level 5
being the highest level. A separate password can be defined for each level, except
level 0.
Only level 5 users can define and modify access level definitions, and change
passwords.
Access for levels 4 to 1 can be defined as follows:
•
no access to the function (NO_ACCESS)
•
read-only access (READ_ONLY)
•
read/write access (READ/WRITE)
The default is read/write access.
Level 5
Level 5 is intended for use by system managers, providing read and write access to
all functions. Level 5 cannot be redefined but it can be assigned a password.
Levels 4 to 1
Levels 4 to 1 are used to meet the requirements of the following types of user.
Table 11-2 lists suggested access level definitions.
•
Level 4 (system manager)
The user is managing housekeeping functions related to user access and Control
card non-volatile memory maintenance functions.
•
Level 3 (network configuration operator)
The user configures network interfaces, signaling, data processing applications,
system serial ports, date and time.
•
Level 2 (network performance operator)
The user manages alarms, statistics, diagnostic tests and circuit or position
maintenance.
•
Level 1 (network performance personnel)
The user collects information on abnormal system conditions or significant
events.
Level 0
Level 0 is a read-only access defined for one or both serial ports. Level 0 users have
access to all softkeys except PROCEED. When enabled, level 0 access has no effect
on access levels 5 to 1.
If a serial port is configured for level 0 access, a user may log in at level 0 or any
other level. If a serial port is configured for no level 0 access, users must enter a level
(5 to 1) and password to log on.
