Abstract

PURPOSE:To achieve test for a plurality of exchanger systems at the same time, which have a common line signal device without a test device, by setting a spare line in a communication network from a central virtual call generating system to a work test station. CONSTITUTION:At one location at least in the country, a central virtual call generating system is installed, a spare line in a communication network is temporarily set to a work test station, and a virtual call is generated from the central virtual call generating system for test with the instruction information such as test mode transmitted from a tele-typewriter of the exchanger system. For example, a centralized virtual call generating system CPGS consisting of a common controller CPU, common line signal device SGU and continuity tester CT is connected to work test stations 1-n with spare lines SC1-SCn. From the instruction information transmitted from a tele-typewriter TTY equipped with the test stations 1-n via the common line signal device SGU, a virtual call is transmitted to the centralized virtual call generating system.
