Abstract

A distribution point unit to exchange communication data between a service provider and subscribers. The distribution point unit may include a first port to couple the distribution point unit to an optical data network to exchange communication data between the distribution point unit and the service provider, and a second port to couple the distribution point unit to an electrical data network to exchange the communication data between the subscribers and the distribution point unit. The distribution point unit may also include a third port to couple the distribution point unit to an electrical device, the third port being configured to provide control data to control the electrical device.

First claim
