I thank all who answered my question. I now know some details about the equipment I was asking about. Where does the following equipment fall in the European Directives and standards scheme?
It is a loop back device used by telephone company repair people. It allows "ringing out" telephone wire pairs from a remote distance. A typical use would be to "alligator clip" this device at local switching hub (building, neighborhood, etc.) and then to remotely determine which pairs are which. It has the ability to take commands by touch-tone tones to inject tones onto the lines (below 3 kHz) and to switch pairs. It runs on a 9 volt battery and is not intended to be used on a telephone line that is in use.
