Rehoming a DLSAM between ports residing on a first switch includes establishing a physical loop-back circuit between a second port and a temporary input port of the first switch; establishing an ePVC between the input port and a first port, the first port coupled to a first connection; removing a PVC and establishing a new PVC; routing data between the second switch and the DSLAM via the new PVC, the circuit, the ePVC, and the first connection between the first switch and the DSLAM; removing the circuit from the second port; establishing a second connection between the second port and the DSLAM; routing data between the second switch and the DSLAM via the new PVC and the second connection; removing the ePVC between the first port and the temporary input port; and disconnecting the first connection between the first port of the first switch and the DSLAM.

Method and system for rehoming a digital subscriber line access multiplexer

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.

Systems and methods are disclosed for providing network testing. The disclosed systems and methods may include connecting to at least one element within a network. Furthermore, the disclosed systems and methods may include performing a test on the network through at least one element. The test may be associated with at least one addressable device connected to the network. In addition, the disclosed systems and methods may include analyzing data associated with the test.

A method for moving permanent virtual circuits in an ATM network with minimal downtime includes creating a list of the permanent virtual circuits to be moved; building a set of shadow permanent virtual circuits using the new ATM port and a temporary set of virtual path identifier and virtual circuit identifier pairs; moving a physical connection from the original ATM port to the new ATM port; deleting the permanent virtual circuits on the original ATM port; and changing the shadow permanent virtual circuits to use the original virtual path identifier and virtual circuit identifier pairs.

Method for moving network elements with minimal network outages in an active ATM network

A method and system are provided for rehoming a digital subscriber line access multiplexer between a first data switch and a second data switch or ports on a single data switch. An extension permanent virtual circuit is established between the first data switch and the second data switch and a physical loop-back circuit is established at the second data switch for routing data from an output port of the second data switch to a temporary input port. A permanent virtual circuit between a data switch servicing a network service provider and the first data switch is removed, and a permanent virtual circuit between the data switch servicing the network service provider and the second data switch is established. Data is then routed 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 switch, the physical loop-back circuit, and the extension permanent virtual circuit.

Reporting tools used to manage an asynchronous transfer mode (ATM) network. Tools include a trunk inventory reporting tool, a trunk utilization reporting tool, an exceptions reporting tool and a flow control processor activation utility. Reports generated by these the tools include information about the operation and capacity of trunks, switches and user network interfaces.
