    摘要: A frequency band selection device that can be inserted into a signal transmission line of a CATV system on the premise of a user includes at least two signal path sets between a tap side and a premise side. Each signal path set includes two discrete signal paths, a high frequency signal path for a downstream bandwidth and a low frequency signal path for an upstream bandwidth. The high frequency signal path and the low frequency signal path are separated by a cut-off transition frequency that is different for each signal path set. The device further includes a switch controller having at least two discrete switch positions. The switch controller chooses one of the switch positions as a result of an information signal. Each of the switch positions corresponds to a respective one of the signal path sets.

    摘要: A network interface device including a signal splitter which conducts CATV signals through an active branch circuit, the active branch circuit including an active signal conditioner which modifies characteristics of active branch signals conducted through the active branch circuit, a sensor connected to sense normal, inoperative and abnormally operative conditions, the sensor removing a control signal indicative of inoperative and abnormal operating conditions, a selectable switch connected to the active branch circuit, the selectable switch communicating the CATV signals between the CATV network and the subscriber devices when in an activated position, and the selectable switch passing the signals to a signal reduction path when in a deactivated position, the selectable switch assuming the deactivated position in response to the de-assertion of the control signal, and a phase cancellation circuit connected to the signal reduction path.
