high-speed, high-volume, packet-switching transmission protocol standard.
ATM uses short, uniform, 53-byte cells to divide data into efficient, manageable
packets for ultrafast switching through a high-performance communications
network. The 53-byte cells contain 5-byte destination address headers and
48 data bytes. ATM is the first packet-switched technology designed from
the ground up to support integrated voice, video and data communication
applications. It is well-suited to high-speed WAN transmission bursts.
ATM currently accommodates transmission speeds from 64 Kbps to 622 Mbps.
ATM may support gigabit speeds in the future.]
