Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic exchange, and more particularly to a subscriber line test system.

2. Description of the Related Art Conventionally, this type of subscriber line test system has two independent lines between a subscriber and a subscriber line test stand for a speech path and subscriber line measurement data.

Problems to be Solved by the Invention However, the above-mentioned conventional subscriber line test method is
There are drawbacks that the line cost becomes enormous because two lines are used for each of the communication path and the data line, and that the central processing unit must control two lines.

The present invention has been made in view of the above circumstances,
SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a new connection difference line test system capable of eliminating the above-mentioned drawbacks inherent in the conventional technology.

Means for Solving the Problems In order to achieve the above object, the subscriber line test system according to the present invention uses a subscriber line test device, a subscriber circuit, and a network to connect a subscriber line from a subscriber line test stand. In a subscriber line test system to be tested, a switch for switching between a call state and a data transmission state and a subscriber line test are executed by the subscriber line test device arranged between the subscriber circuit and a switching switch. And a modem for transmitting the data measured by the measuring circuit to the subscriber line test stand, and a CPU for switching control of the switch, and the subscriber line test stand sent by a maintenance person. The PB sound from the CPU controls the switching of the path from the communication state between the subscriber and the subscriber line test stand to the data transmission state in which the data resulting from the subscriber line test is transmitted. It is characterized in Rukoto.

Embodiment Next, the present invention will be described in detail with reference to the drawings for a preferred embodiment thereof.

FIG. 1 is a block diagram showing an embodiment of the present invention. In FIG. 1, the subscriber line test stand 8 by the maintenance person
When the subscriber 1 to be tested is designated by using, the central processing unit 6 recognizes it and the subscriber 1 to be tested goes through the subscriber circuit 3 and the subscriber circuit test equipment 4 to make a subscriber line test stand. 8 is connected in a call state (mode).

After the instruction to the subscriber 1 to be tested from the maintenance person, the PB sound from the subscriber line test stand 8 switches the call state (mode) to the data transmission state (mode) with the switch in the subscriber line test apparatus 4. And the measurement of the subscriber line 2 is executed.

FIG. 2 is a block diagram showing a concrete example of the subscriber line test apparatus 4. In the figure, for example, when the relay contact 41 is in the illustrated state, it is in a call state (mode), and in this state, when the maintenance person sends out a PB sound from the subscriber line test stand 8, this PB sound is measured by the contact 41, the measurement. It reaches the CPU 43 through the circuit 42. The CPU 43 switches the contact 41 by this PB sound, and sets the data transmission state (mode) in which the data output as a result of the subscriber line test is transmitted. In this state, the measurement circuit 42 executes the test of the subscriber line 2, passes the test result data through the modem 44 and the contact 41, and further through the exchange switch 5 and the subscriber line test trunk 7. Transmit to test bench 8.

EFFECTS OF THE INVENTION As described above, according to the present invention, the line for communication and the line for data transmission are shared and used, so that the line cost and the central point at the time of setting the path for communication / data transmission are set. The occupation rate of the processing device 6 can be reduced.
