1. A method, comprising:

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

    converting, by the NID, the electromagnetic waves to first electrical signals that convey the first DSL signals;

    providing, by the NID, the first electrical signals that convey the first DSL signals to a first DSL device;

    receiving, by the NID, second electrical signals from the first DSL device, wherein the second electrical signals convey second DSL signals; and

    transmitting, by the NID, the second electrical signals into the conductive material internal to 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 internal to the transmission medium.
