XCON: X.25 Support for SAT Cards

• Microsoft Exchange Server, versions 4.0 and 5.0

SUMMARY

The Microsoft Exchange Server documentation states that the Eicon cards are the only X.25 cards supported by Microsoft Exchange Server. This is not true; in some cases X.25 cards manufactured by SAT are also supported.

MORE INFORMATION

The statement that only Eicon cards are supported refers only to the installation of the X.25 protocol stack within the Microsoft Exchange Server Administrator program. Currently only Eicon cards can be used for an X.400 connector using a native X.25 connection.

There are, however, three ways to use an SAT X.25 board with a Microsoft Exchange Server computer.

• One way is to configure a software PAD on top of both X.25 boards. Then a RAS connector is configured between the two Microsoft Exchange Server computers.
• The two other configurations require the XLAN-IP product to route the IP protocol over the X.2 physical link. On the computer running Microsoft Exchange Server, either configure a site connector
• or add a TCP/IP stack and configure an X.400 connector. This solution has the advantage of supporting both a site connector and an X.400 connector. On the other hand, it produces more protocol overhead and is not suited to very slow X.25 connections (less than 9,600 baud).

REFERENCE

SAT is an X.25 board manufacturer whose Atlantis X.25 for Windows NT and Atlantis X.25/ISDN PCI for Windows NT cards are supported by Microsoft Exchange Server on Windows NT versions 3.51 and 4.0. To contact SAT:
