This module provides RADIUS Client. It sends users’ information a specified
RADIUS server and then takes actions according to different responses made by
the server. The RADIUS server generally runs on a workstation. Its task is to
receive requests from customers, authenticates users’ authority, and returns
configuration information necessary for customers to provide service for users.
The database in the RADIUS Server stores all security information. The Radius
Client and Radius Server implement AAA functions based on the RADIUS
protocol.

interface module. They are described as follows:
1. Configuration
module
Both the SCBF and line interface board have system configuration modules,
which complete respective tasks.
