1. A method of determining an ATM network topology in an ATM network by which a plurality of ATM switches and a plurality of ATM terminals are interconnected, each of said ATM terminals having at least one respective port and each of said ATM switches having a respective plurality of ports through which each of said ATM switches and ATM terminals is directly connected to its neighboring ATM switches and ATM terminals;

  • said method comprising the steps of;

    storing, in each respective one of said ATM switches and ATM terminals, a respective switch identifier that indicates whether said respective ATM switch or ATM terminal is an ATM switch;

    exchanging said respective switch identifier between said respective ATM switch or ATM terminal with those of its neighboring ATM switches and ATM terminals;

    determining, for each respective port of said respective ATM switch or ATM terminal, whether a network node interface for connecting two neighboring ATM switches is present or whether a user-network interface for connecting an ATM switch and an ATM terminal is present using said exchanged switch identifiers; and

    automatically setting a data communications protocol format that corresponds to said determined interface and which identifies said respective ATM switch or ATM terminal.
