Rapidly being deployed by telephone companies and enterprise customers, ATM represents for many the next generation for LAN switching. Its ability to accommodate the simultaneous transmission of data, voice and video is enabling a spectrum of new applications, including those supporting real-time voice and video. ATM is a networking technology that has very high expectations to improve transmission speeds. It has the capability to condense and transmit video, voice and data over a single line. Its speeds far outrate those of LANs using Token Rings or Ethernet.
