Abstract

The drop wiring from an optical network unit (ONU) to a customer premise includes one or more working circuits and at least one auxiliary circuit. The network interface device at the customer premises is switchable. The interface device normally couples the working circuits to corresponding customer premises wiring circuits. The ONU and the switchable network interface device (SNID) can be automatically activated to activate communication via the auxiliary circuit. For example, if a primary telephone circuit fails or is predicted to fail, the ONU is automatically instructed to place the telephone communications on the auxiliary circuit, and the network instructs the SNID to connect the auxiliary circuit to the customer premises telephone wiring. The automatic activation and switching also facilitates automatic provision of a second line service using the auxiliary circuit.
