### Configuring RAS Ports on Windows NT 4.0

This topic describes how to configure Digi devices as RAS ports (sometimes called RAS capable devices).

#### Procedure

1. To access Windows NT RAS, choose Control Panel > Network > Services > Remote Access Services > Properties.

2. To add a modem port to the RAS configuration, do the following:

   - Click Add > Install Modem.

   - Choose Don't detect my modem; I will select it from a list and then click Next.

   - From the list, select Digi Int'l 56K Modem and then click Next.

   - Install this modem type on the ports you want to use for RAS and then click Next > Finish > OK.

3. If you have a RAS B or RAS P/T/E adapter and want to add an ISDN port (B-channel) to the RAS configuration, do the following:

   - Click Add.

   - Select a B-channel from the list in RAS Capable Devices and then click OK.

4. If you have a Sync 2000 or SYNC/570 adapter and want to add an X.25 switched virtual circuit (SVC) to the RAS configuration, do the following:

   - Click Add

   - Select an X.25 SVC from the list in RAS Capable Devices and then click OK.

5. To configure the port, do the following:

   - Select the port from Remote Access Setup and click Configure.

   - Specify Dial out only, Receive calls only, or Dial out and Receive calls, and then click OK.

6. To configure the network protocols to use over a port, do the following:

   - Select the port.

   - Click the Network button to access the protocol-specific configuration.

   - Use Microsoft's help text to guide you through the network protocol configuration. If you plan to use Multilink PPP over this connection, ensure that Multilink is selected.
