Broad-band service distribution method for separating broad-band front end of receiver from rest of circuit - involves placing separated broad-band end of receiver in fibre node or utility closets of building for connection to coaxial cable, and then connecting front end to ASDL modem

摘要

The method for distributing broad-band services involves separating a broad-band front end of a receiver from other portions of a circuit. The front end is placed in the utility closets of a building, and is connected to; a modulator-demodulator (ASDL modem); a modulator or an amplifier. A signal is transferred from the ASDL modem and from a telephone exchange to an adder in order to mix the broad-band and telephone services. The signals are transferred over a telephone wire pair to an individual end user. The broad-band front end of the receiver is located in a fibre node and connected to a broad-band hybrid fibre-coaxial (HFC) network where the optical signal arriving from the fibre is converted into an electrical signal for transmission on coaxial cable.
