12713020-003-2 Revision F.01 – January 2007 SSU-2000 Technical Reference 33
Chapter 2 TL1 Reference
System Security
The SSU-2000 system software allows you to set up a list of users with one of five
access levels; each level has an increasing level of access to system functions and
commands. Each incremental access level incorporates all of the options from the
lower numbered access levels and additional options at that level. For instance, a
User-level user does not have as many options available as a Technician-level user.
An Administrator-level user assigns the access level to each user when the user id
and password is created. Table 2-2 summarizes each access level, ID number, and
the operator privileges for each level.
TL1 Retrieve Commands and Responses
This section contains an alphabetical listing of TL1 retrieve commands, a
description of the command which provides the valid aid codes to use in the
command, and an example and description of the components of message lines.
Table 2-2. User Access Levels
Level ID Description
Idle 0 Access level 0 is available when no user is logged in. This level allows
Idle-level users to view a list of available commands (HELP), syntax, software
version number, unit id, or to login.
User 1 Users at the User level can execute level 0 commands and view information
about the current configuration and operation, and change communication
settings such as line termination and echo. Changes made by a User-level
user remain in effect only until the user logs out.
Technician 2 Users at the Technician level (CRAFT persons) can perform levels 0 through 1
functions, and can read or set all installation functions.
Supervisor 3 Supervisor-level users can execute all commands at levels 0 through 2, and
can read or set all functions.
Administrator 4 Administrator-level users can execute all levels of commands; they can view
and set software configurations; they can also add, delete, or modify the user
table, or log off any user from any port.
