How to Create an X.400 Protocol Stack

You must create a protocol stack on the Exchange server that will host the connector before you create an X.400 connector. The protocol stack is created on individual Exchange servers and provides the underlying functionality for the connector to transport messages.

Procedure

To create a transport stack

1. In Exchange System Manager, expand Protocols, right-click X.400, point to New, and then select either TCP/IP X.400 Service Transport Stack or X.25 X.400 Service Transport Stack.

2. On the General tab, type a name for this transport stack.

   The following names are the default names:

   • X.25<server name>

   • TCP <server name>

3. (Optional) Under OSI address information, select the character set and the selector information if other applications use this transport stack.

   The following figure shows the General tab of the Properties dialog box for a TCP/IP X.400 transport stack. On this tab, you can configure the transport stack. Any connectors that you configure to use this transport stack appear on the Connectors tab.

   Note

   When you first create the connector, the Connectors tab does not list any connectors.

4. (Optional) On the General tab of an X.25 transport stack (see the following figure ), set the following X.25-specific configuration options:

   • Based on the information supplied by your X.400 service provider, type the appropriate values for Call user data, Facilities data, and the X.121 address of the remote X.25 provider.

   • For I/O port, type the port number that is used by the X.25 adaptor. (If you have multiple X.25 X.400 transport stacks on a single server, each stack must use a different port number.)
