1. A method, comprising:

  • receiving, by a network interface device (NID), electromagnetic waves guided by an insulated surface of a transmission medium, wherein the transmission medium is coupled to the NID, wherein the transmission medium has an electrical return path to enable a flow of electrical signals in a conductive material of the transmission medium, wherein the electromagnetic waves propagate along the insulated surface of the transmission medium without requiring the electrical return path, and wherein the electromagnetic waves convey first digital subscriber line (DSL) signals;

    providing, by the NID, first electrical signals that are based upon the electromagnetic waves to a first DSL device, wherein the first electrical signals convey the first DSL signals; and

    transmitting, by the NID, second electrical signals received by the NID from the first DSL device, wherein the second electrical signals convey second DSL signals, wherein the transmitting is into the conductive material of the transmission medium, wherein the second electrical signals received from the first DSL device that convey the second DSL signals are directed to a second DSL device, and wherein the electrical return path of the transmission medium enables the second electrical signals to propagate along the conductive material of the transmission medium.
