Abstract

See full text

A network includes a facility for transmitting baseband telephone signals, plural subscriber locations, and twisted pair circuits which connect each subscriber location to the baseband telephone facility. The network further includes apparatus for transmitting and receiving broadband signals over the twisted pair circuits. A broadband transmitter is coupled to a network twisted pair circuit and outputs a broadband signal for delivery to a subscriber location. A first twisted pair circuit is utilized as an intermediate transmission path for the broadband signals. A distribution module is coupled to the first twisted pair circuit and is connected to a destination subscriber location via a destination twisted pair circuit. First filter circuits are connected in the network twisted pair circuit; are transparent to the baseband telephone signals and block the broadband signals. Second filter circuits are connected in the first twisted pair circuit; are transparent to baseband telephone signals and block the broadband signals. A coupling circuit connects the first and second filter circuits and enables passage of broadband signals from the network twisted pair circuit to the first twisted pair circuit, and then to a distribution module and to a broadband destination location.
