Abstract
PURPOSE: To perform appropriate test with a simple system without using the line test by communication lines, by using one set of a plurality of terminal units installed in one branch as the virtual center to perform the on-line mode test for other terminal units.
CONSTITUTION: The terminal units 1a, 1b installed in one branch are normally connected to the modulation and demodulation units 6a, 6b via the switches 2a, 2b respectively and connected to the center via the communication lines 4a, 4b. Next, in performing the on-line mode test of the terminal units 1a, 1b, the switches 2a, 2b are changed over to the test side, the terminal units 1a, 1b are connected with the straight line 6, one terminal unit 1a is used as the test unit, and the remaining terminal unit 1b is used as unit to be tested. Further, the test unit is operated with the program for the virtual center, and the terminal unit 1b at the side to be tested is operated as normal operation program, allowing to enable the on-line mode test of the terminal unit 1b at the side to be tested.
