Abstract
PURPOSE:To continuously test a subscriber line by a simple operation, or to optionally test a specific line, by switching a call signal sending line of a subscribers' common circuit by disignating and controlling a line from a testing device, and leading it into the testing device. CONSTITUTION:When executing a subscriber line test, call signal sending control relays RG1-RGn of a subscribers' common circuit 7 are operated in order by operating and controlling an indicating counting circuit CNTR in a testing device 6 by use of a line driving key ST, and by its contact, a call signal sending relay R is operated, and a subscriber circuit 4 is set as call signal sending state. On the other hand, since a test line leading-in key TEST is operated, a test line leading-in relay T of the subscribers' common circuit 7 is operated. Accordingly, subscriber lines LA, LB are led into the testing device 6 by the contacts t1, t2, and desired various subscriber line tests can be executed.
