ABSTRACT:
In a cable restoration system neon devices and light-emitting diodes are utilized to identify corresponding conductors in a broken cable by an arrangement that does not require the assistance of a lineman at the central office. The apparatus identifies a central office line by means of a neon device and ringing bridge arrangement which replaces the neon indicating bulbs used in prior art systems. After identifying a customer line at a cable break by using indicating devices in a conventional manner, a maintenance man at the break location dials the central office over a spare pair. When ringing is applied to the desired central office line, a glow discharge occurs in the neon device, which discharge heats a bi-metallic strip and causes the strip to move and establish a metallic short across the line. The short trips ringing extinguishing the discharge. The bi-metallic strip cools and the short is removed from the line. The maintenance man then applies a high frequency tone signal to the spare pair which signal appears on the desired line after passing through the central office. The tone is detected by a ringing bridge and used to illuminate a light-emitting diode which identifies the desired line.
