Abstract :
With the aid of a new automatic number identification (ANI) system, direct distance dialing (DDD) is being provided to telephone customers served by small step-by-step offices. This paper describes this new system designated ANI Type-C. Electronic and electromechanical techniques are used with glow lamps serving as major circuit elements. A brief review of previous ANI developments is also included.
