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.
