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.
Claims20
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 through a first amplifier and for exclusively a downstream signal, a second signal path through a second amplifier and for exclusively an upstream signal, and a third signal path through a third, single amplifier;
- and
- at least one switch that selectively alternates a signal through the third, single amplifier between an upstream signal and a downstream signal.
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 through a first amplifier and a second signal path through a second amplifier;
- and
- at least one switch that alternately routes a mid-band signal through a respective one of the first amplifier and the second amplifier.
