ABSTRACT:
A portable test set is disclosed for rapid pair identification, polarity determination, and half-tap verification in conjunction with modular testing apparatus employed in splicing cables--particularly cables used in the telephone industry for interconnecting telephone switching systems and subscriber equipment. Switchable meters operating in combination as a single indicator are provided for determining individual line pair conditions prior to execution of simultaneous multiple pair splicing operations to prevent customer inconvenience or loss of service. The test set is adapted for mating with contemporary modular splicing equipment through the interface typically provided therein. The test set is particularly characterized by incorporating no internal power supply as is the usual case in such equipment but, rather, operating totally from voltages present in the cables under test.
