Abstract: A digital interface apparatus and system for cable television systems and digital service are disclosed. The apparatus includes a housing with an input and two outputs. The housing includes a surge protection circuit connected to the input and to a signal dividing circuit that is connected to an output and a filtering circuit that is connected to another output.
Abstract: An electrical grounding suppressor device, and the method of using the same, which is placed directly in line with the co-axial center conductor of cable television distribution lines without inhibiting or causing significant loss of the radio frequency signal in the co-ax line. An electronic circuit senses a transient surge on the co-ax line and triggers a rapid clamping action to ground to dissipate the harmful effects of the surge.
