Abstract
From a central point, both telephone signals and Class-2 high frequency electric power are transmitted by way of a common transmission cable to the location of a telephone apparatus; thereby to provide at that location, not only telephone signals, but also a limited amount of electric power useful for various things, such as task lighting. At the central point there is provided a non-interruptible source of electric energy, namely a frequency-converting power supply connected both with an ordinary 120 Volt/60HZ power line as well as with a storage battery. This power supply provides output of Class-2 high frequency voltage. Together with the telephone signals, this Class-2 voltage is transmitted by way of an ordinary telephone installation cable to the location of a telephone apparatus. At that location, some of the wires in the telephone installation cable are connected with the telephone apparatus, and some of the wires in the telephone installation cable are connected with a fluorescent task lighting fixture designed to be properly powered from the Class-2 power-limited high frequency voltage.
