Environmental Engineering (EE); Reverse powering of access network unit by end-user equipment: A4 interface
|Publication Date:||1 June 2010|
The present document scope is the back feeding or reverse powering architecture that can supply power to access network unit such as ONU or ONT or remote DSL unit from the customer through its final distribution access copper pair.
As a minimum, the present document defines a power interfaces over the customer copper pair to the access network unit (remote DSL unit or ONU such as FTTC or FTTB cabinet) defined in TR 102 629 [i.21].
Other important issues are under discussion in the present document: overlay of PSTN on the same pair and back-up (autonomy, locations, environments and safety), reliability and monitoring aspects are also addressed.
Other issues about local laws, unbundling rules, and cost are out of the scope.
