ATM was intended to provide a single unified networking standard that could support both synchronous channel networking (PDH, SDH) and packet-based networking (IP, Frame relay, etc), whilst supporting multiple levels of quality of service for packet traffic.
ATM sought to resolve the conflict between circuit-switched networks and packet-switched networks by mapping both bitstreams and packet-streams onto a stream of small fixed-size 'cells' tagged with virtual circuit identifiers.
ATM will remain deployed for some time in higher-speed interconnects where carriers have already committed themselves to existing ATM deployments; ATM is used here as a way of unifying PDH/SDH traffic and packet-switched traffic under a single infrastructure.
ATM is highly scalable and supports transmission speeds of 1.5, 25, 100, 155, 622, 2488 and 9953 Mbps (see OC).
When ATM came on the scene in the early 1990s, it was thought to be the beginning of a new era in networking, because it was both a LAN and WAN technology that could start at the desktop and go straight through to the remote office.
ATM adapters for the desktop were expensive, and standards for interconnecting existing networks to an ATM backbone were confusing and often delayed.
