Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for testing subscriber lines in a switching system.

[Conventional technology]

Conventionally, this type of subscriber line testing method provides the telephone number of the subscriber under test from a subscriber line test stand.
The central processing unit recognized the subscriber's telephone number, converted it into a subscriber line accommodation location number, and connected the subscriber line to the subscriber line test stand.

[Problem that the invention seeks to solve]

In the conventional subscriber line testing method described above, the subscriber line is determined by the subscriber telephone number from the subscriber line test stand, so if you want to test the subscriber line in the order of the subscriber line accommodation position number, There was a drawback in that it had to be converted into a subscriber's telephone number and the converted subscriber's telephone number had to be sent out again from the subscriber's line test stand.

[Means for solving problems]

In order to eliminate such drawbacks, the present invention transmits subscriber line accommodation position information from a subscriber line test stand to an MF signal receiving circuit via a trunk for subscriber line testing, and in this MF signal receiving circuit, the subscriber line The identification code provided at the beginning of the accommodating location information determines whether this subscriber line accommodating location information is a subscriber telephone number or a subscriber line accommodating location number, and the result of this determination and the subscriber line accommodating location number are This central processing unit connects the subscriber circuit and the subscriber line testing equipment using an exchange switch, and also connects the subscriber line testing equipment and the trunk for subscriber line testing to test the subscriber line. This test was designed to perform the following tests.

[Effect]

In the present invention, it is possible to connect a subscriber line to the subscriber line test stand by inputting the subscriber telephone number from the subscriber line test stand, and it is possible to connect the subscriber line to the subscriber line test stand by inputting the subscriber line accommodation position number. Can be connected to subscriber line test stand.

[Embodiment] A test system for explaining an embodiment of the subscriber line testing method according to the present invention is shown in the figure. In the figure, 1 is a subscriber's telephone, 2 is a subscriber's line, and 3 is a subscriber's telephone.
is a subscriber circuit, 4 is a subscriber line test device, 5 is an exchange switch, 6 is a central processing unit, 7 is a trunk for subscriber line testing, 8 is a subscriber line test stand, and 9 is a subscriber line test stand.
This is an MF signal receiving circuit.

Next, the operation of the test system configured as described above will be explained. The subscriber line accommodation location information, which is the subscriber telephone number or the subscriber line accommodation location number input by the maintenance person using the subscriber line test paper table 9, is sent to the MF via the subscriber line test trunk 7. The signal is input to the signal receiving circuit 9.

The MF signal receiving circuit 9 determines whether the subscriber line accommodation location information is a subscriber telephone number or a subscriber line accommodation location number based on the identification code provided at the beginning of the subscriber line accommodation location information. The MF signal receiving circuit 9 transmits the result of this determination and the subscriber line accommodation position number to the central processing unit 6.

The central processing unit 6 checks the subscriber circuit 3 based on the information output from the MF signal receiving circuit 9, confirms that the subscriber telephone 1 is in an idle state, and uses the exchange switch 5 to connect the subscriber circuit 3 and the subscriber line. The test device 4 is connected, and the subscriber line test device 4 and the subscriber line test trunk 7 are connected.

In this way, in this system, regardless of whether the subscriber telephone number or the subscriber line accommodation position number is input from the subscriber line test stand, the subscriber line 2 is connected to the subscriber line 2 via the subscriber line test trunk 7. It can be connected to the subscriber line test stand 8, and the subscriber line 2 can be tested.

〔Effect of the invention〕

As explained above, the present invention transmits the subscriber line accommodation location information, which is the subscriber telephone number or the subscriber line accommodation location number, from the subscriber line test stand to the MF signal receiving circuit, and the MF signal receiving circuit Based on the identification code provided at the beginning of the line accommodation location information, it is determined whether this subscriber line accommodation location information is a subscriber telephone number or a subscriber line accommodation location number,
The determination result and the subscriber line accommodation position number are sent to the central processing unit, and the central processing unit connects the subscriber circuit and the trunk for subscriber line testing. Since the subscriber line and the subscriber line test stand can be connected regardless of the subscriber line accommodation location number entered, there is no need to convert the subscriber line accommodation location number to the subscriber telephone number, which improves maintenance efficiency. It has the effect of increasing

Claims (1)

[Claims] 1. The subscriber line accommodation location information, which is the subscriber telephone number or the subscriber line accommodation location number, is transmitted from the subscriber line test stand to the MF signal receiving circuit via the subscriber line testing trunk, and the MF signal receiving circuit Based on the identification code provided at the beginning of the subscriber line accommodation location information, it is determined whether this subscriber line accommodation location information is a subscriber telephone number or a subscriber line accommodation location number, and the result of this discrimination and the subscriber line accommodation location information are The accommodation position number is transmitted from the MF signal receiving circuit to the central processing unit, and this central processing unit connects the subscriber circuit and the subscriber line testing equipment using an exchange switch, and also connects the subscriber line testing equipment and the subscriber line testing equipment. A subscriber line testing method characterized by testing subscriber lines by connecting them to trunks.
