Asynchronous Transfer Mode

The synchronous Transfer Mode is an International Telecommunication UnionTelecommunications standards section for cell relay wherein information for multiple service types, such as voice, video, or data is conveyed in small, fixed sire cells. ATM are connection oriented. ATM standard is widely accepted by common carriers as mode of operation for communication. It is a form of cell switching using small fixed sired packets. ATM network will be organized as a hierarchy. Asynchronous transfer mode is quickly evolving to enable the full use of Broad Band Integrated Services Digital Network.
