Abstract: A system and method are presented for demarcating an optical network. The system comprises an optical monitor that receives a portion of an outbound signal from an optical network and generates a switch control signal based on the intensity of the outbound signal. Generally, the switch control signal is active when the intensity of the outbound signal falls below a threshold value. Alternatively, the system comprises an override switch, and the switch control signal is active when the override signal is activated or the outbound signal falls below a threshold value. An optical switch receives the switch control signal, and selectively isolates the network generating the outbound signal from the rest of the network when the switch control signal is active.

Abstract: Several examples for in-home Voice-Over-Internet Protocol (VOIP) telephony distribution are described. In one example, an analog telephone adapter may be modified to provide wireless capabilities. In another example, an isolation device or circuit may be added to a Network Interface Device or a Central Office. In yet another example, a second pair of wires may be used to provide VOIP service. As a result of implementing any one of these examples, a user may place a VOIP call throughout the user's home without being tethered to a fixed location.
