Abstract:
1. A method for rehoming a digital subscriber line access multiplexer between a first data port and a second data port, both of which reside on a first data switch, the method comprising: establishing a physical loop-back circuit between the second data port and a temporary input port of the first data switch; establishing an extension permanent virtual circuit between the temporary input port and the first data port, the first data port coupled to a first data connection between the first data switch and the digital subscriber line access multiplexer; responsive to establishing the extension permanent virtual circuit, removing a permanent virtual circuit between a second data switch, the second data switch servicing a network service provider and the first data port; establishing a new permanent virtual circuit between the second data switch servicing the network service provider and the second data port; responsive to establishing the new permanent virtual circuit, routing data between the network service provider and the digital subscriber line access multiplexer via the new permanent virtual circuit between the second data switch the second data port, the physical loop-back circuit, the extension permanent virtual circuit, and the first data connection between the first data switch and the digital subscriber line access multiplexer; removing the physical loop-back circuit from the second data port; establishing a second data connection between the second data port and a port on the digital subscriber line access multiplexer; responsive to removing the physical loop-back circuit, routing data between the network service provider and the digital subscriber line access multiplexer via the new permanent virtual circuit between the second data switch and the second data port and the second data connection between the second data port and the digital subscriber line access multiplexer; removing the extension permanent virtual circuit between the first data port and the temporary input port; and disconnecting the first data connection between the first data port of the first data switch and the digital subscriber line access multiplexer.
