Abstract
A customer interface device for coupling a customer site to a VDSL-based video, voice and data distribution network includes a signal splitter for separating incoming narrowband and broadband from a single twisted-pair copper wire, a narrowband port for connection to existing telephone wiring at the customer site, and a broadband port for connection to a customer set-top box via a CAT 5 wire. The interface device further includes a high pass filter connected between the splitter and the narrowband port, and a low pass filter connected between the splitter and the broadband port. The filters improve broadband signal quality while preventing feedback of EMI noise from the existing building wiring to the network.
