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, the first data switch comprising an asynchronous transfer mode 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; removing a permanent virtual circuit between a second data switch and the first data port, the second data switch comprising an asynchronous transfer mode switch; establishing a new permanent virtual circuit between the second data switch and the second data port; routing data between the second data switch and the digital subscriber line access multiplexer via the new permanent virtual circuit, 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; routing data between the second data switch and the digital subscriber line access multiplexer via the new permanent virtual circuit and the second data connection; 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.
