<p>The invention relates to a circuit arrangement for coupling an information device and a digital device to a local area network cable having at least first and second twisted wire pairs, and simultaneously carrying a two-way digital data signal and an information signal, the circuit arrangement comprising:
a first local area network connector connectable to the local area network cable;
a second local area network connector connectable to a digital device for coupling the two-way digital data signal to the digital device; and
an information connector couplable to the information device for coupling the information signal to the information device,
wherein each of the first and second twisted pairs is operative to carry a digital data signal, and the at least two twisted pairs cooperatively form a phantom channel operative to carry the information signal.</p> |
