Windows NT Single Channel Access (CAPI)

The RVS-COM installation makes several RVS-COM (CAPI compliant) modems available. Once they are added as modems and set up under RAS, you are ready to set up your Dial-Up connection.

1.Set up the Dial-Up Networking connection by selecting Programs>Accessories>Dial-Up Networking.

2.Click New. Provide a descriptive name for this connection and enter the phone number for your remote server or ISP.

3.Next, select the CAPI (RVS-COM) modem and COM port for this connection in the Dial- Using field.

4.When complete, click the Server tab and verify the Dial-Up server type. Click the TCP/IP settings tab if you need to specify IP addresses for your remote server or DNS. Contact your ISP or network administrator for information on configuring this screen.

5.Click OK to return to the Network Dial Up folder.

To use this connection, highlight the connection and click Dial. Your ISDN adapter will connect within seconds.

Windows NT Multilinked Channel Access (CAPI)

Before a second channel can be linked using CAPI, a second port must be defined within RVS-COM.

1.To make the second port available, open the RVS-COM Comm Center.

2.Click the Services tab. In the Virtual COM Ports section of the window, place a check mark in front of both ports. Associate each port with a unique COM port number (the two devices must use different COM ports.) Click Apply, then OK.

If the second CAPI device has not been installed add a second RVS-COM modem and make it available through RAS as described previously in this section.

You are now ready to create your Dial-Up Networking connection for multilinking. In this example, the Single Channel Access connection will be modified to allow for multilinking.

1.Click on Programs>Accessories>Dial-Up Networking.

2.Select the Single Channel CAPI connection and click More. Select Edit entry and Modem Properties.

3.In the Dial Using list box, select Multiple Lines.

4.Next, press Configure. Place a check mark in the box associated with the two RVS- ISDN lines you will be linking.

5.Highlight the first line and select Phone Numbers. If not previously entered, enter the phone number for this line. Click Add and OK.

6.Highlight the second line and select Phone Numbers. If not previously entered, enter the phone number for this line. Click Add and OK.

To use this 128K MLP Dial-Up connection, click Programs>Accessories>Dial-Up Networking. Double click on this newly created CAPI multilink connection. Both phone lines on your MultiModem ISDN adapter will connect in seconds.
