JPS631230A - Terminal adaptor having circuit test function - Google Patents

Abstract

PURPOSE:To enable a terminal adaptor to perform a circuit test independently or in coorperation with another device against a terminal and/or a circuit terminating equipment, by providing a circuit test function to the terminal adaptor. CONSTITUTION:A circuit test function 17 is stored in a memory 5 and a circuit test is started when a plug 3 is put into a socket. These information are displayed by a display device 13. When a test is given to a terminal 2, a terminal adaptor 1 informs the terminal that an incoming call is received and sends the message received from the terminal 2 back to the terminal 2. Then the adaptor 1 sends a clear signal to the terminal 2 and waits for presence or absence of an answer. Meanwhile the time monitor is carried out to check whether or not a prescribed answer is received within a prescribed monitor time. For a test given to a circuit terminating equipment 15, an incoming subscriber number is supplied via a keyboard 19 for calling and the response given from the incoming side is waited for. Then the message is sent to the incoming side together with the clear signal and an answer is waited for. Meanwhile the same time monitor is carried out.

Of course, during the above processing, display is performed on the 1 display 13 via the display control unit 12 as necessary.

[Problem that the invention seeks to solve]

Conventionally, a terminal adapter 1 as described above has been produced, but when, for example, a line test is to be performed with a higher-order line termination device (NT), the terminal adapter 1 itself has a calling function, etc. Therefore, the above line test is only possible with the terminal 2 attached.

Means for Solving the Problem c] The present invention solves the above problems by providing a terminal adapter with a line test function.

FIG. 1 shows a basic configuration diagram of the present invention. The symbol l in the figure is a terminal adapter, and 2 is a terminal.

3 is a plug, 14 is a digital telephone, 15 is a line terminal (NT), 16 is a switched network switch (LS), 1
7 represents a line test function provided in the present invention.

The terminal adapter 1 has conventionally had a function of converting the signal system for the terminal and the signal system for the line terminating device, but in the present invention, it has a line test function corresponding to the terminal and/or the line terminating device. 17. The line test function 17 is stored in a memory to be described later, and the test is performed by a processor executing the contents of the memory.

[Effect]

The above line test function is activated by activating the test start by inserting the plug 3 into the socket.
It will be done. This fact is displayed on the display. Terminal 2
Is it a test that corresponds to the side?

For example, a key indicates whether the test is for the line termination device 15 side.

In the case of a test on the terminal 2 side, terminal adapter 1 notifies terminal 2 that there is an incoming call, and
Processing is performed such as returning the message from the terminal 2 to the terminal 2, sending a message to the terminal 2, and waiting for a response.

During that time, monitoring is performed for two hours, and it is checked whether there is a predetermined response within the predetermined monitoring time.

In the case of testing on the line termination device 15 side.

Enter the number of the called subscriber from the terminal adapter 1 and make a call. 2. Wait for a response from the called party. 9. Send a message to the called party. 1. Send a response signal to the called party and see if there is a response. Processing such as waiting is performed. During that time, the same time monitoring as above is performed.
