On the other hand, it is possible to automatically test the call function for the subscriber of the private exchange regardless of time, it is possible to shorten the time to test the entire call function.

Description

Apparatus for testing call simulator of Private Branch Exchange}

The present invention relates to a subscriber call function test apparatus of an premises exchange, and more particularly, to an apparatus capable of automatically switching a line for all subscribers when testing a call function of a subscriber line of an premises exchange. It is about.

First of all, PBX stands for Private Branch Exchange.

An internal exchange is an exchange which performs exchange connection between the extension telephones of the premises (local telephone line) telephones or between the extension telephones and the trunk lines (telephone telephone telephone lines) at workplaces such as government offices, companies, factories and hotels.

The branch exchange system is a revolving premises exchanger that performs all connections such as incoming / outgoing connections from trunk lines to stations, outgoing connections from stations to trunk lines, and interconnections between stations. After the change, it has evolved and developed into an electronic branch exchange (EPBX) of accumulated program control method using a microprocessor or IC memory.

The Electronic Branch Exchange (EPBX) has the ability to perform more than 100 different services, such as timed calls and simultaneous data transfer, and has become an indispensable device in the establishment of local area networks, as well as ISDN. .

There are two types of currency path methods: the spatial division currency path method and the time division currency path method. A digital PBX, which encodes and exchanges an audio signal (analog signal) in several forms of electric signals, is called a digital PBX.

Digital PBX connects OA devices such as PCs, word processors, and facsimile machines used in the premises to convert and multiply data and voice into digital signals so that multiple signals can be simultaneously transmitted and communicated on a single line (transmission path). .

Therefore, the digital PBX is a key device of the digital network, which is a higher communication means, and occupies a very important position for effective LAN construction and ISDN construction.

When testing the call function of a general telephone line connected to such a branch exchange, connect the Local Call Simulator (LCS) equipment with the regular telephone subscriber line, assign the telephone number of the corresponding telephone line to the LCS equipment, and then test 32 subscribers at a time. After the test, the investigator moves the line to the next subscriber, continues the test by changing the telephone number of the LCS equipment, and performs the test for the entire subscriber in this manner.

In the call function test of the digital telephone line, the digital phone was directly connected to the digital telephone subscriber line of the product, and the tester performed a sensory test by directly calling all the subscribers.

However, this method must be resident when the tester tests the call function of a general telephone line, and in the case of testing a digital telephone line, the sensory test is performed to deteriorate the test detection power and the quality of the product. there was.

Therefore, the present invention was devised to solve such problems, and an object of the present invention is to test the call function for the general telephone line of the local exchange, and then perform the unit test by connecting the LCS equipment to the subscriber line. In the case of investigating the call function of the digital telephone line of the branch exchange, the tester develops a call function test equipment with automatic transfer function to eliminate the problem that the tester must always reside to move the subscriber line every time, and to increase the test detection power. In order to eliminate the problems caused by the tester's call and the sensory test for all subscribers by connecting the digital phone directly to the subscriber line, we developed a call function test with automatic transfer function to improve test detection power and product quality, and automatically A device that can reduce the test time of the entire arc function of the product by testing the arc function of In the gongham.
