1. A node configured to receive respective scheduled upstream data signals from each of a plurality of modems and propagate received signals further upstream, each modem connected to the node by a respective one of at least two Radio Frequency (RF) legs, the node comprising a steering subsystem configured to control a switch to selectively isolate the respective scheduled upstream data signals from noise present on any said RF leg not propagating a scheduled upstream data signal, the switch controlled using information from reservation MAPSs, provided to the steering subsystem by a scheduler subsystem, and which define a predetermined schedule of upstream transmissions for each of the plurality of modems.
