Abstract
A method and system are provided for rehoming a digital subscriber line access multiplexer between a first data port and a second data port on a data switch. The method includes establishing a physical loop-back circuit between the second data port and a temporary input port of the data switch, establishing an extension permanent virtual circuit between the temporary input port and the first data port, removing a permanent virtual circuit between a data switch servicing a network service provider and the first data port, establishing a permanent virtual circuit between the data switch servicing the network service provider and the second data port, and routing data between the network service provider and the digital subscriber line access multiplexer via the permanent virtual circuit between the data switch servicing the network service provider and the second data port, the physical loop-back circuit, and the extension permanent virtual circuit.
