Abstract

There are big opportunities to replace the present AC-UPS systems by introducing 300 V single mode parallel operating system in telephone exchange facilities. In doing this, one can expect higher accessibility and extended back-up times. As an extension of this, all 48 V system can eventually be abandoned at a pace when servers and routers will handle a greater part of the telephone traffic. To ease the implementation, a unanimous view regarding the necessity of having a standardised interface is needed, as well as a certification for 300 V DC of today´s AC fed equipment.
