Abstract

PURPOSE:To execute efficiently a test by providing a test signal generator for testing a channel of a link device, in a facsimile response device, providing a test signal detector in the link device, and switching the channel of the link device at a high speed by a command from a central control unit at the time of a test. CONSTITUTION:Under a control of a central control unit 1, a facsimile information signal is sent out of a facsimile response device 2, and connected to a trunk circuit corresponding to the other party for sending-out, by a link device 3. This link device 3 is used for connecting selectively one line the facsimile response device 2 to one line of plural other parties for sending-out (trunk circuits). In this state, in accordance with a fact that the channel of the link device 3 is closed successively by a command of the central control unit 1, the device is controlled so that switches of switching devices 6, 7 are connected to a test signal generator 4 and a test signal generator 5. In this way, if a fault exists in the channel of the link device, it is detected by the test signal detector 5, reported to the central control unit 1, and the fault can be detected instantaneously.

FIG. 1 is a block diagram of a facsimile response link device showing an embodiment of the present invention. In FIG. 1, 1 is a central control unit;
2 is a facsimile answering device, 3 is a link device, 4 is a test signal generator, 5 is a test signal detector, and 6 and 7 are switchers for switching signal paths during testing. In this figure, a facsimile information signal is sent out from a facsimile answering device 2 under the command of a central control device 10, and is connected to a trunk circuit corresponding to the destination by a link device 3. This link device 3 is for selectively connecting one line of the facsimile answering device 2 to any one line of a plurality of destinations (trunk circuits). Here, according to a command from the central control device 1, the switches of the changeover devices 6 and 7 are connected to the test signal generator 4 and the test signal detector 5 in response to the sequential closing of the communication paths of the link device 3. control like this. As a result, if there is a fault in the communication path of the link device, it is detected by the test signal detector 5 and reported to the central control device 1, so that the fault can be detected instantaneously. According to this embodiment, it is possible to efficiently test the communication path of the link device 30 by simply providing the test signal generator 4 and the test signal detector.
