Description

Subscriber Line Test Panel Structure of Electronic Switching System

The present invention relates to a subscriber line test panel structure of an electronic switchgear, and more particularly, to easily test a subscriber line of a plurality of subscribers assigned to the electronic switchgear using a single test panel. The present invention relates to a subscriber line test panel structure of an electronic switching system.

As is well known, an electronic exchange has been developed and adopted as a part of meeting the call exchange function having a digital switching function and a distributed control structure on a public telephone network, which is the basis of the information and communication field. As the TDX-based TDX-1 exchanger has been developed as an electronic exchanger, a TDX-10 exchanger capable of accommodating a large number of service subscribers has been developed and used in consideration of the characteristics of various communication networks.

According to these electronic switchboards (such as TDX-10 switches), it can accommodate up to 100,000 subscribers and 60,000 trunks of digital trunk lines, and has 26,000 Erlang traffic handling capacity, 1,200,000. It not only has BHCA (Busy Hour Call Attemps) call processing capacity but also has a TST-type switch network structure, which has 8,192 time-switch and 63 × 63 matrix-type space-switch. It has a group switch structure with).

In addition, such an electronic switchboard can provide not only the voice exchange service of a general telephone but also a non-voice exchange service such as a video, and a conference (6 person) call function for up to 6 subscribers to talk simultaneously. When the operator inputs the function registration and the called number, the direct call function automatically sends a call to the called number registered at the time of the subscriber's hook-off, and the subscriber waits for the call. It has a wide range of applications, such as a call waiting deny function, which informs the exchange not to perform a function and thus denies service.

On the other hand, in the electronic switchboard, various functional tests are performed through subscriber lines for a plurality of subscribers assigned to it, for example, special service call processing and operation test, analog subscriber test, and relay call function test. And subscription tests.

In other words, in order to perform a functional test on a large number of subscriber lines of an electronic switchgear, the call connection between the subscriber and the exchange period is cut off, and test equipment such as a telephone is connected to the subscriber line and divided into tip and ring lines. DC line voltage between line, Tip-Ground line and Ring-Ground line, test items such as AC voltage, loop resistance, insulation resistance, capacitance, etc. It is possible to check the normal service status.

Here, in the test of the subscriber line, the test phone is directly connected to the tip and ring terminals for each subscriber line in the subscriber block installed on the back board of the electronic switchboard, and the off-hook detection is performed. In the state of connecting to the Tip and Ring terminals provided to individual channels of each subscriber line, there is a possibility of instability during test verification caused by inadvertently connected abnormally and the inability to call due to short circuits. However, there was a problem that it takes a long test time due to careful attention to accurately connect the test phone to the tip and ring terminals of each channel.

Therefore, in order to solve such a problem, recently, a plurality of channel-specific connectors have to be provided on the tip and ring terminals of each channel of the subscriber block installed on the back board of the electronic switchboard through a certain length of signal lines, and the signal lines have a certain length. A test panel of subscriber lines is proposed which allows the inside of the cable to pass through.

However, in the case of the test panel of such a subscriber line, a plurality of channel-specific connectors are installed to connect the tip and ring terminals of each channel so that the connector of the test phone can be connected to the pins of the connector corresponding to the channel of the desired subscriber line. In order to reduce misconnection of a line and test time for a long time, but there are a plurality of connectors that integrate and connect channels of each subscriber line, so check the connector pins installed in the connectors for each channel individually. As it should be correctly connected to the test phone, there is still no solution to the problem of time-consuming and incorrect connection.

Accordingly, the present invention has been made in view of the above circumstances, and includes a single test panel for testing a subscriber line assigned to an all-electronic exchange, and integrates a plurality of subscriber channels and a single test panel through a test cable. It is an object of the present invention to provide a subscriber line test panel structure of an all-exchange electronic exchange that enables easy test checks on subscriber lines by connecting channels.

In order to achieve the above object, according to the subscriber line test panel structure of the electronic switch according to the present invention, a plurality of upper / lower subscriber channel connectors integrally connected to channels for a plurality of subscriber lines and a plurality of channels, respectively, A test panel having a plurality of test channels corresponding to the number of tip pins and ring pins of the subscriber channel connector integrated with a plurality of subscriber channels and a test connector integrated with the plurality of test channels. Subscriber line of an all-electronics exchanger comprising a test cable having a first cable connector connected to a test connector of the test panel and a second cable connector at the other end selectively connected to the plurality of upper / lower subscriber channel connectors. Provide a test panel structure.

Preferably, the present invention further comprises an interface connector connected to a second cable connector of the test cable to interface with a plurality of upper / lower subscriber channel connectors.

According to the present invention configured as described above, RS-232C is connected to a predetermined subscriber channel connector among a plurality of subscriber channel connectors installed on the backboard side of the electronic switchboard and integrating and connecting channels for a plurality of subscriber lines by a plurality of channels. Selectively connected by one cable connector provided in the connecting cable such as a single cable having a plurality of test channels so as to correspond to the number of connection pins according to the Tip and Ring terminals of each subscriber channel connector. By connecting to the test connector of the test panel, it is possible to easily test the subscriber line through the selective connection to a plurality of subscriber channel connectors.
