ATM is a1connection-oriented technology, in which a connection is established between the twoendpoints before the actual data exchange provides a highly complex technology, with features intended for applicationsranging from global telco networks to private local area computer networks.

The full suite of ATM standards provides defi-nitions for layer 1 (physical connections), layer 2 (data link layer), and layer 3 (network) of the classical OSI seven-layer networking model.
