Abstract: A probing signal transmitted on a twisted pair telephone line in a DSL system is reflected and received at a DSL device. An estimate of one of a DSL data transmission signal or DSL synch symbol transmission signal is removed from the received probing signal to recover the reflected probing signal. The recovered reflected probing signal is processed to determine characteristics information of the twisted pair telephone line.

Abstract: An apparatus comprises at least one vectoring engine and a cross-connect coupled to the vectoring engine. The cross-connect is to couple with each of a plurality of customer premises equipment (CPE) devices via a respective DSL loop. An interface is to receive instructions for the cross-connect to couple the vectoring engine to a nonoverlapping subset of the CPE devices via the respective DSL loops. The interface is further to receive instructions for the vectoring engine to apply vectoring to the DSL loop via which to couple one of the CPE devices to the cross-connect.
