Method and apparatus for transceiver noise reduction in a frame-based communications network

A switch apparatus for providing noise reduction for a received signal in a transceiver communicating frames over a transmission medium in a frame-based communication network, the transceiver having a transceiver transmit path and a transceiver receive path, comprising:

• a blocking switch locatable in the transceiver transmit path, the blocking switch having an input port and an output port allowing transmit signal propagation through the blocking switch and along the transceiver transmit path when enabled, the blocking switch further including enable/disable control to disable the blocking switch when the transceiver transmit path is not transmitting frames over the frame-based communications network preventing both transmit signal propagation and circuit device noise coupling from the transceiver transmit path to the transceiver receive path when the blocking switch is disabled so as to reduce noise in the received signal.
