Abstract:
1. A method comprising: receiving, with an access node, an Ethernet operations, administration, and maintenance (OAM) Loopback frame from an originating device within an Ethernet network; constructing, with the access node, an Asynchronous Transfer Mode (ATM) OAM End-to-End Loopback cell from the Ethernet OAM Loopback frame; and transmitting the ATM OAM End-to-End Loopback cell from the access node towards a virtual circuit connected to a subscriber device within an ATM network to verify end-to-end connectivity from the originating device within the Ethernet network to the subscriber device within the ATM network, wherein constructing the ATM OAM End-to-End Loopback cell from the Ethernet OAM Loopback frame comprises translating data from one or more fields of the Ethernet OAM Loopback frame into a source identification (ID) field of the ATM OAM End-to-End Loopback cell.
