Automatic File Transfer

The current demonstration application is Automatic File Transfer (AFT) over X.25. AFT is used to download billing data from DMS-100 telephone switches made by Nortel Networks. In this application, a PXS directly connected to a switch using X.25 downloads billing records and forwards them to a remote file server over TCP/IP where they are written to disk. During operation, the PXS logs its activities to a remote log server.

For the demonstration, ARC supplies the remote file server and log server software as well as a control application to start and stop the PXS. The software is available from our web site in the file This documentation explains how to install the software and run the demonstration.
