Abstract:
1. A system for providing data communications between a first digital subscriber line data device and a network switch comprising: a pilot branch for communicating with the first digital subscriber line data device via pilot signals when the first digital subscriber line data device is in a sleep mode; a data branch for providing data communications between the first digital subscriber line data device and the network switch when the first digital subscriber line data device is active; and a controller circuit for monitoring the pilot signals and for switching the first digital subscriber line data device from the pilot branch to the data branch when the first digital subscriber line data device becomes active based on the pilot signals; wherein the controller circuit comprises a crosspoint device for switching the first digital subscriber line data device from the pilot branch to the data branch and for switching a second digital subscriber line data device from the data branch to the pilot branch when the first digital subscriber line data device is switched from the pilot branch to the data branch in response to the controller; and wherein the controller circuit monitors operation of the second digital subscriber line data device and, based on the monitored operation, instructs the crosspoint device to switch the second digital subscriber line data device.
