1. A method for identifying which client devices are coupled to which radio frequency (RF) ports of a node, the method comprising:
assigning, with one or more control circuits, some of the client devices instructions to transmit data;
assigning, with the one or more control circuits, others of the client devices idle grants;
switching, with the one or more control circuits, an RF switching network situated between the RF ports and a plurality of optical ports of the node from a first state to a second state; and
identifying, with the one or more control circuits, one or more client devices of the some of the client devices that are delivering the data to a predefined optical port of the plurality of optical ports.
