Abstract
Abstract An arrangement for testing a plurality of subscriber lines, which are operationally connected to an electromechanical switching system is shown. Operational service is to be transferred from the electromechanical switching system to a digital switching system. This arrangement provides for automatically verifying the connection of the subscriber lines to the digital switching system and determining whether the proper ring signalling is transmitted to each subscriber.
