Abstract: An optical network unit (ONU) is installed to communicate with an optical line terminal (OLT) located at a remote terminal (RT). The ONU includes a first subscriber downlink interface to serve a first subscriber premises and a second subscriber downlink interface to serve a second subscriber premises. The RT is located apart from a central office (CO) and in communication with the CO. A first removably attachable subscriber downlink module is communicatively coupled to the first subscriber downlink interface. A second removably attachable subscriber downlink module is communicatively coupled to the second subscriber downlink interface. The first removably attachable subscriber downlink module is replaced with a third removably attachable subscriber downlink module. An optical transmission medium is connected between the third removably attachable subscriber downlink module and the first subscriber premises while retaining a second electrically conductive medium communicatively coupled to the second subscriber downlink interface.

Abstract: A communications network is operated by providing a plurality of redundant links between a first network node and a second network node. A first identifier is associated with a first one of the plurality of redundant links and a second identifier is associated with a second one of the plurality of redundant links. The first and second identifiers are associated with the regulatory constraint. Traffic that is marked with the first identifier is routed to the first one of the plurality of redundant links and traffic that is marked with the second identifier is routed to the second one of the plurality of redundant links so that operation of the communications network is in compliance with the regulatory constraint.
