Patent ID: 7145865

Claim:
A method for moving a plurality of permanent virtual circuits in an ATM network from a first ATM port to a second ATM port, said method comprising: creating a list comprising the plurality of permanent virtual circuits to be moved, wherein the list comprises a first plurality of virtual path identifier and virtual circuit identifier pairs; building a plurality of shadow permanent virtual circuits, wherein the plurality of shadow permanent virtual circuits use the second ATM port, and wherein the plurality of shadow permanent virtual circuits comprise a second plurality of virtual path identifier and virtual circuit identifier pairs; moving a physical connection from the first ATM port to the second ATM port, wherein moving a physical connection from the first ATM port to the second ATM port comprises removing a first physical connection between a digital subscriber line access multiplexer and the first ATM port and then establishing a second physical connection between the digital subscriber line access multiplexer and the second ATM port; deleting the plurality of permanent virtual circuits on the first ATM port; and changing the plurality of shadow permanent virtual circuits to use the first plurality of virtual path identifier and virtual circuit identifier pairs.
