ATM
Since 1988, the asynchronous transfer mode (ATM) has been used to transport large amounts of data over telephone lines. The transmission takes place at high speed. That’s why ATMs are often used in high-performance networks with very high transmission rates. The rapid transmission is achieved by splitting the data, regardless of size and type, into small packets. The size of the split packets is 53 bytes each. 48 bytes of a packet are available for the actual information. The remaining 5 bytes are necessary for the transport to the desired destination and the reassembly there.
