Abstract
A system for automated pre-testing of subscriber pairs prior to final transfer from an old telephone office to a new digital central office. The system combines a known line verification tester, a trunk transition system, and an optional line ringing tester interconnected through a novel micro computer based interface. The interface controls the tests performed by the line verification tester and line ringing tester prior to transfer of tested circuits to the central office.
