Solution:

WAN Access for NT (WAC) is a software package written by The Software Group, Ltd.,(TSG) based in Barrie, Ontario, Canada.  Digi no longer OEMs or supports this package as its own.  

There are two versions of WAC presently being used by customers, 1.0.9b and 1.2.1.  Although the driver and software installation is similar for each, the protocols supported for each differ.  For technical support, you will need to contact The Software Group, Ltd.

Protocol support provided by WAC:

Both versions also include a completely documented SYNC API, including source code examples, headers, and API specifications. The use of Frame Relay, X.25, or HDLC will require the implementation of this API within the customer's application.

The PPP, SNA, and the IP Over protocols will not, under normal usage, entail the utilization of the SYNC API.

Known Issues/Limitations:

• The S/570i 4port PCI adapter is not fully supported. WAC is not limited to a single line of the adapter for running Frame or X.25. If running Frame on one line and X.25 on another, you will be able to use two lines.
• With v1.2.1, installing SNA or PPP excludes all other supported protocols from being available. This affects the entire server.
• WAC  is licensed software, requiring one unique license per server. If the WAC protocol services detect a duplicated license, it will initiate a random timer. Once expired, the protocol stack being used will be stopped, forcing you to reboot the server.
