Interface between Data Terminal Equipment (DTE) and Data Circuit-Terminating Equipment (DCE) for Operation with Packet-Switched Data Communications Networks. Category: Hardware Standard. Subcategory: Data Transmission

摘要

This joint Federal Information Processing Standard (FIPS) and Federal (Telecommunication) Standard (FED-STD) specifies the means of interfacing automated data processing (ADP) equipment and services, as well as telecommunication system terminal equipment, with packet-switched data communication networks. It is based on Recommendation X.25 which was developed and approved by the International Telegraph and Telephone Consultative Committee (CCITT) of the International Telecommunications Union (ITU). Recommendation X.25 contains a large number of options and implementation alternatives, which if exercised in different ways would impede the interoperability of equipment and services. This joint standard limits these options and alternatives in order to satisfy the vast majority of Federal user requirements for interconnections with packet-switched data communications networks.
