Abstract
An ATM exchange which is comprised of a multistage cascade connection of ATM switches of self-routing module structures which are provided with a plurality of outgoing lines and incoming lines, wherein it provides at the output side and the input side of the ATM switches output side conversion interfaces and input side conversion interfaces both for connection of adjoining ATM switches and uses optical cables to connect the output side interfaces and input side interfaces facing thereto. By this, it is possible to maintain the correct exchange operation even if the length of the transfer lines (outgoing lines and incoming lines) laid between ATM switches becomes greater along with extension of the ATM switches in the exchange.
