ABSTRACT:
A method of and a system for exchanging information of payload field of ATM cells wherein the minimum exchanging unit is 1 byte removing the limitation of the current ATM exchanging unit to 48 bytes (1 cell). The payload fields of ATM cells are divided into units of 8.times.N bits to effect exchanging operation, and the exchanging operation is performed by a function of copying ATM cells and rearrangement in position of information of payload field. The rearrangement in position of information of payload field is performed by a position switch which performs rearrangement within an ATM cell and between ATM cells. The position switch selects divided part informations in the payload fields with a signaling signal. The division of the payload field into units of 8.times.N bits may be a division other than a division beginning with the first bit of an ATM cell immediately following a header.
