Asynchronous Transfer Mode (ATM) is the hottest network to technology in the marketplace, enabling extremely high-speed transmission of all user traffic, including voice, data and video. The UNI3.1 standard enables developers to build equipment that will fully interoperate in today's public and private ATM network environments. This is the only authoritative guide to this new standard, by The ATM Forum, the industry-led consortium that created it.




the authoritative guide to the new ATM User Interface Version 3.1 standard that defines the primary specification for end-system connection to ATM networks.
describes how to build equipment that will interoperate within a high-speed ATM network.
reflects ITU-T recommendations 1,610, Q.2100, Q.220, Q.2130 and Q.2931.
covers the Physical Layer Interfaces Specificatoin, as well as standards for traffic and congestion control, MIBs, Message Functional Definitions and Contents, Support for 64 Kb ISDN Circuit Mode Services, and other specifications.
