The ATM layer in ATM Technology deals with cell transport.
Asynchronous transfer mode:-ATM provides functionality that is similar to both circuit switching and packet switching networks. ATM uses asynchronous time-division multiplexing, and encodes data into small, fixed-sized packets called cells.
Asynchronous data transfer, there is no common clock signal between the sender and receivers. Therefore, the sender and the receiver first need to agree on a data transfer speed.
