Customer premises ADSL signal distribution arrangement
First Claim
1. An arrangement for distributing signals to customer premises, comprising:
- a coaxial cable for supplying television signals at predetermined frequencies to a plurality of customer premises;
a plurality of ADSL (asymmetric digital subscriber line) terminals each for receiving asymmetric signals from, and for communicating telephone and bidirectional signals via, a respective ADSL path; and
a plurality of telephone lines each coupled to a respective one of the ADSL terminals for communicating the telephone signals to a customer premises;
wherein each ADSL terminal includes means for supplying the asymmetric signals to, and for communicating the bidirectional signals via, the coaxial cable at at least one respective frequency different from said predetermined frequencies;
the arrangement further comprising means at at least one customer premises for receiving the asymmetric signal from, and for communicating the bidirectional signals via, the coaxial cable at said at least one respective frequency.

Abstract
A plurality of ADSL (asymmetric digital subscriber line) terminals are coupled to the coaxial cable of a cable television distribution arrangement. Each ADSL terminal is coupled to a respective ADSL path and a respective customer premises telephone line for coupling of telephone signals. Each ADSL terminal comprises a transmitter for supplying asymmetric signals received via the respective ADSL path to the coaxial cable, and transmitters and receivers for communicating bidirectional data and control signals, communicated via the respective ADSL path, via the coaxial cable, in each case modulated at a frequency which is not used for television signals. Customer premises equipment includes corresponding receivers and transmitters. The arrangement permits the ADSL terminals to be used as a resource shared by a plurality of customer premises.
