Power over DSL Extender
Line Powered remote wi-fi Access Point
As computing intelligence becomes smaller and cheaper, more and more applications for remote semi-autonomous devices are becoming evident. Remote cameras are everywhere. Outdoor wifi hotspots are hot sellers. Lately, wearable computers are in the news; eventually small, cheap computers will be stuck on everything, everywhere -- and they will need remote power and communications.
Google Fiber is offering plain old broadband (5M down 1 up) for FREE! Is that where broadband is going now? Will Cable TV companies follow that lead and offer free internet? Wireline Telco's really need to continue to advance their service offerings to stay ahead of the barbarians.
The target application of the system is to provide a combined data and power service for these applications:

The system contains 2 main units:
Central Control Unit (CU) – located at the Exchange which bonds physical connections to DSLAM and power.
Remote Unit (RU) – located somewhere close to the subscriber which provides POE connection. It can utilize 1-12 subscriber pairs.
The CU is a rack-type version where the rack provides the connection facilities and takes 48vDC from CO battery / fuse panel.
17 - 0.0036 x R watts per pair where R is the loop resistance. Solutions available for 1 - 12 pairs.
