Making a V.120 connection

V.120 was designed to allow non-ISDN devices to communicate with the ISDN network. The DIVA LAN ISDN Modem provides support for V.120, so you can connect with such legacy systems. For example, in many countries around the world, Compuserve offers access to their network over ISDN, using the V.120 protocol.

In general, you should use V.120 only when the site you are connecting to requires it. Once the V.120 connection is active, the DIVA LAN ISDN Modem automatically establishes a PPP connection on top of it. This is why you will see this option listed as PPP over V.120 on the configuration screens.

To make a V.120 connection you must do two things:

•Configure the V.120 protocol for the profile that will make the connection.

•Define a V.120 script to automatically log on to your ISP. The DIVA LAN ISDN Modem contains a pre-defined script that should work in the majority of cases. However, you may need to modify this script for your installation.

To configure the V.120 protocol

1.On the Configuration main menu, click V.120. You will see the following page:

2.Define the V.120 parameters to match the settings of the remote site you are going to connect to. For information on each parameter consult the online help by clicking the parameter name.

3.Click Save.

4.On the Configuration main menu, click Connection Profiles.

5.Click Edit for the profile that will make the V.120 connection.

6.Click Connection on the menu bar.

7.Select PPP over V.120 as the Protocol.
