Systems and methods for moving DSL launch points

摘要

A system for scaling vectored DSLAM deployments has a DSLAM interfaced with a cross-connect apparatus. The DSLAM receives POTS signals from at least one bridge connection assembly. When a DSLAM is added at the cross-connect facility, at least one connector of the bridge connection assembly is disconnected from an existing DSLAM and is interfaced with the newly-added DSLAM. By moving the connector to the newly-added DSLAM, a batch of downstream distribution pairs (which are preferably bound by a single distribution cable) are effectively moved from the existing DSLAM to the new DSLAM without having to reconfigure the jumpers of the cross-connect apparatus. Accordingly, it is possible to scale the cross-connect facility to any number of vectored DSLAMs while limiting vector group sizes, thereby reducing the complexity of vectoring operations, without having to perform complex reconfigurations of the cross-connect apparatus.

1. A method for moving a digital subscriber line (DSL) launch point, comprising:
electrically connecting a plurality of feeder pairs bound by a first cable to a first digital subscriber line access multiplexer (DSLAM) through a first cross-connect apparatus and a first multi-pair connector; electrically connecting a first plurality of distribution pairs bound by a second cable to the first DSLAM through the first cross-connect apparatus and a second multi-pair connector; communicating POTS signals from the feeder pairs bound by the first cable through the first DSLAM to the first plurality of distribution pairs bound by the second cable; receiving first digital data at the first DSLAM; transmitting digital subscriber line (DSL) signals based on the first digital data from the first DSLAM through the first plurality of distribution pairs bound by the second cable; disconnecting the first and second multi-pair connectors from the first DSLAM; electrically connecting the first and second multi-pair connectors such that POTS signals propagate from the feeder pairs bound by the first cable to the first plurality of distribution pairs bound by the second cable without passing through the first DSLAM; electrically connecting the first plurality of distribution pairs bound by the second cable to a second DSLAM through a second cross-connect apparatus downstream from the first cross-connect apparatus; electrically connecting a second plurality of distribution pairs bound by a third cable to the second DSLAM through the second cross-connect apparatus; communicating POTS signals from the feeder pairs bound by the first cable through the first plurality of distribution pairs bound by the second cable, the second cross-connect apparatus, and the second DSLAM to the second plurality of distribution pairs bound by the third cable; receiving second digital data at the second DSLAM; and transmitting DSL signals based on the second digital data from the second DSLAM through the second plurality of distribution pairs bound by the third cable.
