  • Ethernet OAM to ATM OAM interworking for loopback capability
    Patent number: 8824308
    Abstract: In general, techniques are described for interworking between Ethernet organization, administration, and maintenance (OAM) frames and Asynchronous Transfer Mode (ATM) ATM OAM cells. For example, an access node in an Ethernet and ATM network may implement the techniques. The access node comprises an Ethernet interface that receives an Ethernet OAM Loopback frame from a device within an Ethernet network. The access node includes a control unit that constructs an ATM OAM End-to-End Loopback cell from the Ethernet OAM Loopback frame, and an ATM interface that transmits the ATM OAM End-to-End Loopback cell from the access node towards a virtual circuit connected to a subscriber device to verify connectivity from the originating device within the Ethernet network to the subscriber device within the ATM network.
