CONFIGURING RESTRICTIONS

1. On the Functions menu, select Users, or click on the toolbar. The User List dialog appears.

2. Select a user that which you want to configure restrictions, or click Add to configure a new user.

The User dialog appears.

3. Select the Restrictions tab.

4. Select 56000 bps or 64000 bps for the Base Data Rate. 64000 bps is the default.

5. Determine the Initial Bandwidth and Maximum Bandwidth. These values do not have to be

multiples of the Base Data Rate.

6. H0 Call Support can be enabled for users who need bandwidth to accomplish large file transfers

or video conferencing. This feature is not cost effective for users who generate a smaller

amount of network traffic.

7. Determine any time restrictions for the user. The default is no restrictions. Disable No

Restrictions in order to configure time restrictions.

Note: If No Restrictions is disabled, you must configure the non-zero values for each

restriction parameter for a specific call direction before the user is allowed to connect.

8. Click Update to write the new information for the user to the database, or click Add to create the

newly configured user.

Note: If you are adding a new user to the database, a User Name must be defined on the

Address tab.

9. Click Close.

ACCESS

SFVRA Connection Manager performs device level security. Device level security is an

authentication process between internetworking devices, in which authentication takes place

automatically. Both bridges and routers support this form of security. An offnode authentication

server can perform User level security as an optional feature. Configure device level security for

each remote device. Group assignments and other features such as call back and compression are

configured in this section.

AUTHENTICATION

DEVICE LEVEL AUTHENTICATION ON SFVRA-CONN

When a remote device calls a CyberSWITCH, the CyberSWITCH accepts the call. The

authentication process begins by the user sending its authentication data to the CyberSWITCH. The

CyberSWITCH passes this information on to SFVRA Connection Manager in an Authentication

Request message. The SFVRA-CONN validates the information against its database, and sends an

Authentication Reply to the CyberSWITCH indicating whether the user is valid or not. If the

remote device is a valid user, the CyberSWITCH will negotiate connection parameters, such as the
