Moving the Power Equipment into the Switching Room

Because of the environmental requirements placed on traditional batteries and the noise emanating from the power equipment, power supply units have always been located separately from the telephony equipment they serve. New technology in power components and batteries has made it possible to install the power in the same room as the telephony equipment. This paper will deal with the gains obtained by moving the power into the telephony room. It will also deal with some alternative system solutions and how Ericsson Power Systems has decided to implement its alternative.
