Abstract
A cable television tap ( ) for receiving a forward signal including an information signal and a power signal. The tap ( ) includes a diplex filter ( ) for receiving the forward signal and for separating the information signal from the power signal at outputs of the diplex filter ( ) and a plurality of subscriber ports ( ) coupled to an output of the diplex filter ( ) for receiving the information signal such that the information signal can be accessed at each of the plurality of subscriber ports ( ). The tap ( ) also includes a removable port device ( ) coupled to the other output of the diplex filter ( ) for receiving the power signal, and the port device ( ) has a connector ( ) so that the power signal can be accessed. According to the present invention, when the port device ( ) is coupled to the tap ( ), the information signal can only be accessed at the subscriber ports ( ), and the power signal can only be accessed at the connector ( ) of the port device ( ). This provides a way to separately transmit the information signal and the power signal over the subscriber property to the subscriber.
