The present invention relates to a test apparatus for an access-gate, and in particular, an access-test apparatus for shortening the time required by automatically testing the interlocking system between the entire systems and suitable for preventing the occurrence of defects. It is about.

In general, an access-gate is referred to as XS-GATE and refers to voice over internet protocol gateway (VOIP) and internet telephony gateway system / circuit multiplexing equipment (ITGS / CME) equipment.

When described in detail with reference to the accompanying drawings of the conventional test device as follows.

1 is a block diagram showing a conventional test apparatus for an access-gate, as shown therein; A reference PBX (private branches exchange) exchanger (20) connected to the test access-gate (10) through an exchanger interlocking cable (11) to test a connection with the exchanger; A reference access gate (30) connected to the test access gate (10) through a system interlocking cable (12) for testing an interworking signaling system between systems; A transmission measuring instrument 40 connected to the exchanger interlocking cable 11 and the system interlocking cable 12 for testing the transmission characteristic of the call path provided by the access-gate under test 10; LCS (50) for confirming that a normal call path is formed by transmitting / receiving a call from the reference PBX exchanger (20) and the reference access-gate (30) through a local call simulator (LCS) cable (13, 14), respectively. Wow; It is connected through the access-gate 10 for test and the operating terminal interlocking cables 15 and 16 to store an operation program of the access-gate 10 for test, to set a test environment, and to output a test result. It consists of a terminal (60).

Then, the LCS 50 generates a call through the reference access-gate 30, checks whether a ring is normally received by the LCS 50 through the reference PBX switch 20, and then LCS 50. By transmitting the test voice band frequency tone in both directions in and confirming that it is normally received, the call function check process of the access-gate 10 under test is completed.

Then, the existing statistical data of the test access-gate 10 under test is deleted, the call test of the LCS 50 is performed, and the statistics generated in the call and test access-gate 10 generated in the LCS 50 are collected. Complete the process of confirming the statistical function by checking that is equal.

Then, by connecting the call path of the test access-gate 10 under test with the reference PBX exchanger 20 through the reference access-gate 30 and measuring the characteristics in the transfer measuring instrument 40 to store the result, Complete the transmission characteristic measurement process.

As described above, all seven connection methods of the reference PBX exchanger 20 are tested with respect to one interworking method of the access-gate 10 under test, and the statistical function and transmission characteristics are confirmed to be normal to determine the abnormality of the system. Done.

However, the test apparatus of the conventional access-gate as described above takes a lot of time as the program loading and system setup proceeds according to the inter-system interworking method of the test access-gate under test, and the tester performs data set-up. There was a problem that could be caused.

The present invention was devised to solve the conventional problems as described above, the object of the present invention is to enable the automatic testing of the interlocking system between the entire system to reduce the time required and to prevent the occurrence of defects. The present invention provides a test apparatus for an access-gate.
