Abstract

PURPOSE: To supervise normality at any point of time by providing a test data generating section and a check section respectively to a network terminal equipment 1 applying line termination of a digital subscriber line and a station-side terminal equipment 2, sending test data mutually for checking.
CONSTITUTION: Test data generating section s 6, 7 generating test data of different patterns and check sections 8, 9 are provided respectively to the network terminal equipment of the terminal equipment 5 and the station-side terminal equipment 2 of the exchange 4 connected mutually by the digital subscriber line 3. Then a test data is sent from the test data generating sections 6, 7 at a prescribed period or communication start, the test data sent from the network terminal equipment 1 is checked by the check section 9 of the station-side terminal equipment 2 and the test data sent from the station-side terminal equipment is checked by the check section 8 of the equipment 1. Or the test data looped back by an opposite equipment is checked to supervise the normality of the network terminal equipment 1, the station side terminal equipment 2 and the digital subscriberline 3.
