摘要:
A switch in an optical network unit selectively couples line side ports of the line cards of the unit to individual line circuits in drop cable wiring extending to the customer premises served by the unit. The switchable optical network unit (SONU) permits rapid automated upgrades of service. For example, automatic switching of a line circuit to a line card offering an upgraded service together with automatic provisioning of the SONU to activate service through that line card provides the new upgraded service over the existing line circuit, without requiring a technician to install a new line card or manually connect the line card to the line circuit. If the drop cable to the customer premises includes a primary line circuit and an auxiliary line circuit, the line port can be switched over from the primary line circuit to the auxiliary line circuit to automatically restore service in the event of a failure of the primary line circuit. Alternatively, the SONU can automatically connect a line card for a new service to the auxiliary line circuit to provide second line service to the customer premise.

摘要:
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.
