Abstract
An apparatus comprising a receiver configured to receive a digital subscriber line (DSL) signal carrying a data burst from a first network element (NE) via a first DSL line in a network, a processor coupled to the receiver and configured to perform frame synchronization to determine a burst timing of the data burst, perform signal amplification on the DSL signal to produce an amplified DSL signal, and determine a transmission time for the amplified DSL signal according to the burst timing of the data burst, and a transmitter coupled to the processor configured to transmit the amplified DSL signal to a second NE over a second DSL line in the network according to the transmission time to facilitate communication between the first NE and the second NE.
