A recommendation for centralized powering of local network elements

The challenge for the telecommunications power engineer is to devise a cost-effective and reliable means of providing power for telephone sets (POTS) over an evolving local network in a manner that allows a smooth transition to the network envisioned. This paper discusses the networks, reviews proposed powering arrangements, and recommends that centralized powering of network elements, with hybrid arrangements for wideband services, be used wherever possible.<
