This article answers the question, “which remote access connection technology breaks up transmitted data into 53-byte cells?”

POTS (plain old telephone service) is still one of the more common methods for connecting remotely to the corporate network. It uses copper wires that already exist in almost every home and office to transmit analog signals, but a little extra hardware attached to the user and switch ends of the line allows much higher data rates than what can be achieved over standard phone wiring using other digital methods such as ISDN and DSL. ATM (Asynchronous Transfer Mode) is a high speed network protocol that uses cell relay technology, but unlike packet switching, it encodes data traffic into fixed length cells of 53 bytes (5 bytes header plus 48 bytes payload) instead of variable size packets.
