BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connection control device for connecting a test stand and an answering machine to enable an automatic response when an operator cannot respond to a call received to a test stand system.

[0002]

2. Description of the Related Art In general, a test bench system responds to an incoming call from the outside by a normal response that an operator operates and responds to, and a response when an operator is unmanned at night or at the convenience of the operator. It has a function that can respond automatically.

FIG. 5 shows a schematic configuration of such a test bench system, which will be described with reference to this. In this test bench system, first, a failure acceptance trunk (CPT) 2 is connected to a telephone exchange 1, and a failure acceptance trunk addition unit (CPTAU) 3 is further connected.

The failure acceptance trunk addition unit 3 is connected to a test equipment (TE) 4 which is composed of a line section, a control section and a test section and has a concentrating function. The test apparatus 4 is controlled by a test control apparatus (TCE) described later via an information line.

Next, the test apparatus 4 includes a failure acceptance / reception trunk (OPOGT) 5 and a failure acceptance / reception trunk (CPIC).
T) 6 is connected to the test controller (TCE) 7. This test control device (TCE) 7 is at the center of the system, receives information between devices, analyzes, edits, transmits, etc., controls the flow of information in the entire system, and has test concentrating functions. It is a device. Further, the test control unit (TCE) 7 is connected to a test stand 9 and a display unit (CRT) 10 via a seat trunk (POS) 8 composed of a call circuit and a keyboard control unit.

Further, the test apparatus 4 and the test control apparatus 7
Central control units (CC) 11 and 12 each formed of a microprocessor are connected to the test stand 9 and the display device 10.

The test bench system configured as described above is
It has operation modes such as normal, nighttime, and answering machine, and each function can be operated by an operator's free choice to respond to calls from the outside.

[0008]

However, in the answering machine mode in the test bench system described above, an incoming call can be transferred to the answering machine telephone terminal in the system to automatically answer, but when the test bench becomes unattended, Since it is designed for reception, all incoming calls are automatically answered, and normal incoming call processing by operators other than answering machines cannot be performed.

In order to avoid this, it is conceivable to connect an answering machine directly to each test stand. However, when this answering machine is provided, the connection control of this test stand system is performed by the microprocessor. The connection train of the test bench does not have a subscriber interface, that is, a function for processing a call to a general telephone terminal and a response processing, and an incoming connection cannot be made.

Therefore, the present invention is to connect and control a test train system in which a call train is controlled by a central processing unit and an answering machine operating on a subscriber line interface without interfering with the operation of the test base by an operator. It is an object to provide an answering machine connection device for a system.

[0011]

In order to achieve the above object, the present invention provides an answering machine capable of answering an incoming call from the outside and a test stand system in which establishment of a call train is controlled by a central processing unit. Answering means for setting the answering machine to answer, incoming call detecting means for detecting an incoming call to the test stand system, and notifying the answering machine of the arrival of the incoming call based on the detection signal of the incoming call detecting means A call signal sending means, a call line establishing means for sending a first pulse signal to the test stand to simulate a response operation when the answering machine answers, and connect the call line to establish a call train; in call train established by the call line establishing means, said second pulse signal is sent to the test stand when it is call termination, false recovery operation of the call line vent story train And to provide a voice mail connection device test stand system composed of a call line recovery means for releasing the vent story line.

[0012]

[Function] The answering machine connection device of the test bench system configured as described above is used for converting the interface between the test bench system and the answering machine and connecting the call line for establishing the call train by the test stand, the restoration control, and the call line interruption. , Answering machine control can be performed, and the answering machine function can be operated in parallel with the operator's test table response.
