X.25 transaction-oriented features - datagram and fast select

The latest proposed revisions to CCITT Recommendation X.25 for packet-switched service in public data networks now include two new capabilities suitable for transport of a small amount of data. The first provides datagram service for the transport of independent "message type" packets. The other new feature is the fast select facility which provides for the inclusion of 128 octets of user data in the call establishment packets for virtual call service. Both these new provisions greatly enhance the capability X.25 to efficiently support the broadest range of user applications.
