Abstract
There is provided a terminate or permit device that includes an internal circuitry, which discriminates between noise and non-noise transmissions. In one embodiment, the internal circuitry comprises a switch and termination unit (“STU”) with a signal path that is used to terminate and/or permit the upstream bandwidth based on the presence of non-noise transmissions. The internal circuitry also comprises a signal processing unit (“SPU”) with a processing circuit, which is configured to identify the non-noise transmissions from the upstream bandwidth, and to cause the STU to permit the upstream bandwidth based on the presence of the non-noise transmissions.
