Security Levels
Each menu item on the configuration screens has an associated secu-
rity level. The security level ranges from 0 (highest security level) to 5
(lowest security level). This level determines whether a Telnet session
can access that menu item. The Telnet session is assigned a security
level set by the user. Passwords can only be accessed as security level
0. The maintenance port is always at security level 0.
The security levels are assigned as follows:
Level
0 Access all parameters including passwords
1 Access all parameters except passwords
2 Access all parameters except passwords and
authentication methods
3 Access all parameters except passwords, authentication
methods, and HDSL parameters
4 Access only test and status menus
5 Access status menus only
