1. An amplifier comprising:
- a first interface operable to exchange signals with a first endpoint;
a second interface operable to exchange signals with a second endpoint;
a first amplifier operable to amplify downstream signaling communicated from the first interface to the second interface;
a second amplifier operable to amplify upstream signaling communicated from the second interface to the first interface;
a gate operably connected between the first interface and the second interface and controllable between at least a first position and a second position, the first position disabling upstream signaling and the second position enabling upstream signaling; and
a detector configured to control the gate between the first position and the second position based on presence of a gate-control signal within at least one of the upstream signaling and the downstream signaling.

Abstract
A duplex communication system having gate-implemented noise management is contemplated. The system may include a gate or other device sufficiently operable to facilitate managing upstream and downstream signaling so as to ameliorate noise funneling between communicating endpoints by selectively controlling communication paths through which noise may be propagated. Optionally, the system may be operably configured to facilitate this type of gate-implemented noise management for time domain duplex (TDD) and frequency domain duplex (FDD) communications.

7. A method of managing noise funneling by controlling a gate included within a communication system, the communication system being configured to facilitate signaling between a first endpoint and a second endpoint, the gate being operable between a downstream position and an upstream position, the downstream position enabling downstream signaling from the first endpoint to the second endpoint and preventing upstream signaling from the second endpoint to the first endpoint, the upstream position enabling upstream signaling from the second endpoint to the first endpoint and preventing downstream signaling from the first endpoint to the second endpoint, the method comprising:
-
detecting for a gate-control signal within the signaling; associating the gate-control signal with the signaling traveling as one of downstream signaling and upstream signaling; facilitating control of the gate to the downstream position when the gate-control signal is associated with downstream signaling; and facilitating control of the gate to the upstream position when the gate-control signals associated with upstream signaling. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17)

18. A method of managing noise funneling by controlling a gate included within a communication system, the communication system being operable to facilitate upstream and downstream signaling between a first endpoint and a second endpoint, the gate being operable between an opened position and a closed position, the opened position preventing upstream signaling from the second endpoint to the first endpoint, the closed position enabling upstream signaling from the second endpoint to the first endpoint, the method comprising:
-
amplifying upstream signaling intended for transmission from the second endpoint to the first endpoint, the upstream signaling being amplified after output from a top-split filter; detecting for a gate-control signal within the amplified upstream signaling; facilitating control of the gate to the closed position when the gate-control signal is detected; and facilitating control of the gate to the opened position when the gate-control signal is not detected. - View Dependent Claims (19, 20)
