Abstract
The present disclosure provides network interface device including a circuit that, in a powered state, receives a downstream radio-frequency (RF) signal from a source via an entry port, provides a portion of the downstream RF signal to a first input/output port via a passive signal path, and provides a second portion of the downstream RF signal to a second input/output port via an active signal path. Additionally, in an unpowered state, the circuit receives the downstream RF signal from the source via the entry port, provides the downstream RF signal to first input/output port via a second passive signal path, and isolates the active signal path and a first passive signal path from the second passive signal path.
