Definition of ATM

 
 Asynchronous Transfer Mode. A data-framing and transmission architecture that features fixed length data cells of 53 bytes, consisting of a fixed format of a 5-byte cell header and a 48-byte cell payload. The small cell size is intended to support high-speed switching of multiple traffic types. The architecture is asynchronous, so there is no requirement for clock control of the switching and transmission.
