The evolution of telecom network architecture and new services have always had impact on powering architecture. The power consumption increases with the generalization of wireless, broadband IP, triple play and services based on computers, and applications are more sensitive to local failure because of high equipment concentration and interdependency. In a context of telecom unbundling, open electricity market, sustainable development, with risks on energy supply and climatic changes, it seems useful to analyse new powering schemes considering parameters as efficiency, reliability, scalability, operation and maintenance simplicity, standard, costs , ... This paper is developing this approach and concluse to the great interest of high DC voltage HVDC interface that is one of those standardized in ETSI EE 300 132-3.
