Abstract: PURPOSE:To attain accurate and quick fault division in an X21 terminal connection by applying central control to the connection state test of a network between terminal equipments having a fault by means of a CPU and each connection test means. CONSTITUTION:Remote test equipments 15a, 15b receiving a command from a CPU 16 command the line disconnection from terminal equipments 11a, 11b and line lead to equipments 15a, 15b to line drawing devices 14a, 14b. When the line lead is finished, the network consists of the equipments 15a, 15b in place of the terminal equipments 11a, 11b. When the equipment 15a sends the dial number of the terminal equipment 11b in a procedure decided by the X21, the terminal equipment 11 receives it when the network is normal. Then the equipment 15a receives an acknowledge to discriminate that the network is normal. The equipment 15b applies the similar acknowledge. Since a fault exists at the terminal side, the faulty terminal equipment is discriminated by the transmission/reception of the equipments 15a,15b with their own terminal equipments 11a, 11b. The result is sent to the CPU 16, then the operator can divide a fault quickly.
