  • Method and apparatus for communications from a non-ATM communication medium to an ATM communication medium
    Patent number: 5420858
    Abstract: An apparatus and method of communicating between devices coupled to two networks. The first network comprises a terminal, containing an Ethernet interface, communication medium and an Ethernet interface contained in a concentrator. The second network comprises an Asynchronous Transfer Mode (ATM) interface contained in a switch, a communication medium and other components of an ATM network. Terminals transmit packets to other devices by: transmitting a packet to the concentrator, the concentrator segments the packet's information into ATM cells, and transmits the cells over the ATM network. The Terminals receive packets from other devices by: the ATM network transmitting cells to a concentrator, the cells being reassembled into Ethernet packets, then the packets being transmitted to the appropriate terminal.
