Remote controlled tone generator system

摘要

A remote controlled tone generator system is provided that permits a telephone technician to remotely control the operating mode of a test tone generator. This allows the technician to install the test generator at the telephone interface, climb the telephone pole and connect the line test monitor, and remotely control the test generator without having to leave his position on the pole. The test generator can operate in the following modes: direct current for polarity test, steady tone and dual tones for line transmission checks, and off for line noise checks. The remote control unit can be a separate module, or it can be built into a conventional technician handset. Alternatively, the tone generator may be controlled by a conventional telephone keypad.
