universal access concentrator, or a Cisco 678. The cell is injected into a
specific virtual circuit along with the normal user traffic flow. The cell is
carried unmodified by each intermediate ATM switching node until it arrives
at the circuit's other endpoint, such as the Cisco 67x. The receiving endpoint
modifies the cell payload to indicate that the cell has been looped-back and
transmits this new cell back into the ATM circuit. It is relayed by each
intermediate node until it arrives at the original transmitting endpoint. The
receipt of this cell indicates a valid end-to-end connection between the two
endpoints over the intervening ATM network.
