Abstract
An apparatus for implementing soft duplex operation of a communications network that transmits downstream signals from a service provider to a subscriber and upstream signals from the subscriber to the service provider. The apparatus may include a pair of opposed triplexers defining a first signal path through a first amplifier and a second signal path through a second amplifier. The apparatus may also include at least one switch that selectively alternates a mid0band signal between an upstream signal and a downstream signal.
Claims8
An apparatus for implementing soft duplex operation of a communications network that transmits downstream signals from a service provider to a subscriber and upstream signals from the subscriber to the service provider, the apparatus comprising:
- a pair of opposed triplexers defining a first signal path for a first frequency range through a first amplifier and for exclusively a downstream signal, a second signal path for a second frequency range through a second amplifier and for exclusively an upstream signal, and a third signal path for a third frequency range through a third, single amplifier, where said third frequency range is between said first frequency range and said second frequency range;
- and
- at least one switch that selectively alternates a third signal through the third, single amplifier between an upstream signal and a downstream signal;
- and
- including at least one gain and tilt module in the path of the third, single amplifier;
- and
- further including different gain and tilt modules for the upstream and downstream directions, respectively.
