<p>PURPOSE:To attain the test individually at every repeater by allowing the test control circuit of the repeater to form a loop path in the order of a test data generator, an incoming transmitter, an outgoing receiver and transmitter and an incoming receiver and error rate measuring device, measuring a code error rate and transferring the rate to a maintenance test equipment. CONSTITUTION:When start of test is instructed from a test control circuit 13 to a maintenance test equipment 4 via a transmitter 8, a loop path for a test data generator 14, a switch 15, a transmitter 8, switches 12, 9, a receiver 5, a transmitter 6, switches 10, 11, a receiver 7 and an error rate measuring device 16 is formed. Simultaneously with the formation of the loop path, an operating signal (c) is sent from the test control circuit 13 to the test data generator 14 and the error rate measuring device 16. A measured signal (g) is sent to the test result processing unit 19 of the maintenance test device 4 via a transmission line 1 and stored in the test result processor 19.</p> |
