9. A digital signal distribution installation comprising:
-
a housing that houses; (a) a coupler linked to an alternating current electrical distribution line and linked to a DSL model with the coupler disposed therebetween, wherein the coupler permits high frequency digital signals carried by the electrical distribution line to pass between the electrical distribution line and the DSL modem while blocking flow of low frequency alternating current to the DSL modem; and (b) a filtering circuit linked to the alternating current electrical distribution line and a plurality of electrical power sockets carried by the housing, the filtering circuit comprising with the filtering circuit disposed therebetween; (1) a pair of inductors with one inductor connected to one branch of the electrical distribution line and the other inductor connected to another branch of the electrical distribution line and providing an impedance that opposes passage of high frequency digital signals to any appliance connected to one of the electrical power sockets; and (2) a pair of resistances with one resistance connected to the one branch in parallel with the one inductor and the other resistance connected to the another branch in parallel with the other inductor. - View Dependent Claims (10, 11, 12, 13, 14)

15. A device for distributing digital signals carried by an alternating current electric power line in a building having a plurality of alternating current power sockets each able to supply alternating current at a voltage, the device comprising:
-
(a) a case having a plug that can be plugged into one of the alternating current power sockets and having a plurality of spaced apart alternating current power sockets each of which can receive a plug of an electrical appliance and a digital signal connector; (b) a coupler linked to alternating current provided to the device via its plug and linked to the digital signal connector, the coupler blocking the alternating current while permitting passage of the digital signals therethrough; and (c) a filtering circuit linked to alternating current provided to the device via its plug and linked to each one of the plurality of spaced apart alternating current power sockets, the filtering circuit blocking the digital signals while permitting passage of alternating current to each one of the plurality of alternating current power sockets. - View Dependent Claims (16, 17, 18, 19, 20)
