Abstract

PURPOSE:To shorten a test time by detecting a connection error between subscriber line confirmation tests being operated simultaneously by attaching a test group number on a subscriber line confirmation test device, and collating a caller number with the test group number. CONSTITUTION:After the caller number sent from a caller number transmission trunk 12 is received at a caller number reception trunk 14, the subscriber line confirmation test device 3a sends the test group number attached individually from a central control unit 2a, and a test group number receiver 16 receives it, and transfers it to the central control unit 2a. The central control unit 2a collates it with subscriber information including the test group number to which a call issuing instruction is issued by its own unit, and outputs it to a maintenance operating terminal 1. When the test group number does not coincide even when coincidence of the caller number is obtained, it means that the call issuing is performed from another subscriber line confirmation test device 3, therefore, it follows that erroneous connection on the wiring board 6 of a subscriber line is performed. In such a way, it is possible to use plural subscriber line confirmation test devices simultaneously.

Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention provides a method for converting subscriber lines from an existing telephone exchange to a new telephone exchange 11! This article relates to an automatic subscriber line confirmation test method that is performed when changing connection to an i-machine.

[Conventional technology]

Conventionally, verification tests of subscriber lines associated with the replacement of telephone exchanges have been carried out by instructing the central control unit with the subscriber line range information to be tested from the maintenance operation terminal of the newly installed telephone exchange, and testing one unit connected to the central control unit. Each subscriber line to be tested is sequentially connected to the subscriber line confirmation test equipment via the subscriber circuit, and the calling number is transmitted from the existing telephone exchange to the central control unit of the new telephone exchange using a signal from the subscriber line confirmation test equipment. It is sent out, checked to see if it matches the subscriber telephone number of the relevant subscriber circuit, and outputs the result to the maintenance operation terminal.

FIG. 2 is a block diagram of a test system for explaining a conventional automatic subscriber line confirmation test method. On the newly installed telephone exchange side in the test system shown in FIG.
, a subscriber line confirmation test device 3b that performs the polarity test 1 call test of the subscriber line, a test link 5 that connects the subscriber line to the subscriber line confirmation test device 3b via the subscriber circuit 4, and an existing test link 5. A calling party number receiving trunk 14 receives a calling party number sent from a calling party number sending trunk 12 provided in a telephone exchange, and a subscriber line receives subscriber line test range information from the maintenance operation terminal 1. The central control unit 2b determines whether the subscriber's connection change is correct or incorrect by instructing the confirmation testing device 3b and verifying the calling party number. On the other hand, on the existing telephone exchange side, there is a call path switch 13, a central control device 11 which controls this and converts the device number of the subscriber circuit 9 into a calling party number, and a new telephone under the control of the central control device]1. a calling number transmission trunk 12 for transmitting the calling number to the exchange; the subscribers 7 are connected to the respective subscriber circuits 4.9 via the main distribution boards 6.10 of both telephone exchanges; ing.

The above-mentioned calling party number sending trunk 12 and calling party number receiving trunk 12
- Rank 14 is equipped with calling party number sending and receiving functions, and is used not only for subscriber line verification tests but also for normal connections.

The automatic subscriber line confirmation test is started by sending the test type and the subscriber line range information to be tested from the maintenance operation terminal l to the central control unit 2b. After capturing 3b, the subscriber line confirmation test device 3b is made to prepare to send a calling party number transmission request number in order to select the calling party number transmission trunk 12 in the existing telephone exchange in an initial setting state. Based on the subscriber line range information to be tested from the maintenance and operation terminal 1, the central control unit 2b selects the subscriber circuit 4, opens a test link 5, and connects it to the subscriber line confirmation test device 3b. In this state, the subscriber line confirmation test device 3b checks that the subscriber line under test is not in use and that there is a polarity error, and if there is a polarity error, it notifies the central controller 2b and outputs it to the maintenance operation terminal 1. let If there is no problem in the check result, the subscriber line confirmation test device 3b connects the test link 5. 41 subscriber circuits Distribution board 6, 10. Subscriber circuit 99 call path switch 3. Verify dial tone via tone generator (not shown). After that, subscriber line confirmation test equipment 3b
sends a calling party ID transmission request number, which is received by a receiver (not shown) in the existing telephone exchange and sent to the central control unit 11.
Transfer to. The central control unit 11 learns that the received information is the information that should transmit the calling party number, and selects and captures the corresponding calling party number transmission trunk 12 and transmits the call from the equipment number of the subscriber circuit 9. It is converted into a calling party number and sent to the calling party number transmission trunk 12. The calling party number transmission trunk 12 corresponds to an outgoing trunk used for normal outgoing connections, and callser number receiving ranks 1 to 14 correspond to large trunks used for normal large connections on the newly installed telephone exchange side. The calling party number is sent from the calling party number transmission trunk 12 to the central control unit 2b via the calling party number receiving ranks 1 to 14. The central control device 2b checks whether the subscriber telephone number matches the subscriber telephone number of the subscriber circuit that originally instructed the subscriber line confirmation test device 3b to make a call, and outputs the result to the maintenance operation terminal 1.

If there are any remaining lines within the range of the subscriber line to be tested, continue to connect the subscriber circuit 4 (not shown) in the pond through the test link 5 from the subscriber line confirmation test device 3b in the same manner, and check the results each time. The test is output to the maintenance operation terminal 1, and the test ends when there are no lines remaining within the range of the subscriber under test.

[Problems to be solved by the present invention]

The conventional automatic subscriber verification test method described above verifies only the calling party number, so if a call test is performed from two subscriber line verification test devices, this distribution board will check if the other subscriber If the personal lines are connected incorrectly,
Since each correct number is received as the calling party number, it is impossible to confirm whether or not they are connected correctly. Therefore, the test can only be performed from one subscriber line confirmation test device at the same time, which has the disadvantage that the test takes a long time.

SUMMARY OF THE INVENTION An object of the present invention is to provide an automatic subscriber line confirmation test method that can be used simultaneously by a plurality of subscriber line confirmation test devices.
