Description

Port and Subscriber Line Test Method in Digital Multiplexer {METHOD FOR TESTING AND SUBSCRIBER LINE IN DIGITAL MULTIPLIER}

The present invention relates to a port and subscriber line test method in a digital multiplexing device.

In general, a digital multiplexing apparatus includes an analog test unit (ATU), which performs a test of abnormality of a voice subscriber line and performance of each port in the unit using PCM data. That is, the existing digital multiplexers have tested by connecting external devices to test the voice subscriber line channel, but the current digital multiplexer implements the ATU in-house to satisfy various functional requirements of the requester. Is testing. Test items of the test unit include a line test, a level test, a dial pulse test, a DTMF test, a dial tone test, and a ring voltage test.

Conventionally, when performing a test using the analog test unit (hereinafter referred to as an ATU), a TCB connection between a user highway and a trunk highway that is already allocated should be suspended, and the connection between the ATU and the user highway should be performed. do. Then, when the result of the set test item is outputted, the TCB connection between the user highway and the trunk highway, which is suspended, is restored. In addition, the test can only be tested for ports whose active state is active.

Therefore, the conventional test can be performed only when the corresponding port is active. Therefore, the ports of all slots must be activated before the test is performed. In addition, among the test items, the level test, the dial pulse test, and the DTMF test should be performed simultaneously in the home country and the large country. This is because it adopts a method of transmitting from the own station node and receiving from the station node. Therefore, there is a problem in that the waste of the personnel and the test efficiency is lowered because the testers located in the own country and the large country must simultaneously transmit and receive the PCM data during the test.

Accordingly, an object of the present invention is to provide a port and subscriber line test method in a digital multiplexing device that can solve the above-mentioned conventional problems.

Another object of the present invention is to enable a test even when the card is mounted only in order to perform a voice level subscriber test using the ATU in a digital multiplexing device more efficiently, and also for the test items that should be transmitted / received in the home country and the country. It is to provide a test method that can automatically test in your own country.

1 is a block diagram of a test module applied to the present invention.

2 is an operation control flow diagram of the call module 3 of FIG.

In order to achieve the above objects, a port and subscriber line test method in a digital multiplexing device tests a non-active port using a separate temporary highway, and a specific test is performed in a message manner using a maintenance channel. It automatically runs a test while exchanging data.

Hereinafter, the present invention will be described with reference to the accompanying drawings.

1 is a device configuration diagram required for the performance of the present invention, in which maintenance module 2, call module 3, ATU 4, SMU 5, user card 6, TCB 7, and trunk 8 driven by operator 1 are shown. . The operator 1 selects a preset test item from a test menu when a test is required. Maintenance module 2 issues commands to the test to CPM module 3 and SMU module 5 to prevent another test from being performed during the test of the set items. In addition, when the test is executed simultaneously between the home country and the country, the test is automatically performed by sending and receiving a message through the NTM and CTM (maintenance / maintenance channel) lines unlike the existing method. Call module 3 receives a command from the RMM 2 and handles a TCB. In the past, only the port in which the corresponding port was activated was able to be tested, but in the present invention, TCB handling is performed by using a temporary highway even for a port that is not active. ATU 4 returns the actual value when a request for a test result is received from SMU 5. SMU 5 provides the command received from the RMM to the ATU and sends the reported result to RMM 2. User card 6, TCB 7, and trunk 8 are handled by the CPM module 3, the performance control flow of the handling is shown in FIG.

Referring to FIG. 2, when the maintenance module 2 indicates that the buffer is being tested in the internal buffer, the CPM module 3 receives a command, and the CPM module 3 that receives the command sequentially performs each step of FIG. 2. After the steps 21-23, the active port is disconnected from the TCB 7 between the user highway 6 of the user card 6 and the trunk highway 8 of the trunk 8, and the connection between the ATU 4 and the TCB 7 is performed. Tests are then made after a TCB connection is made for any non-active ports by specifying an arbitrary temporary highway. This is accomplished by performing steps 24-32.

The RMM module 2 of FIG. 1 then issues a command to the SMU 5 to receive a report indicating the results of the test. In response to the command, the SMU 5 provides a request signal to the ATU 4. The ATU 4 receiving the request sends a result value of executing the test item back to the SMU 5 side to respond. The SMU 5 receives this and sends a result to the RMM 2. After the output for the selected menu is made, RMM module 2 sends a test end signal to CPM module 3. The CPM module 3, which has been terminated, performs steps 33 to 40 of FIG. 2 to release the connection between the ATU 4 and the TCB 7 and execute the TCB connection between the user highway and the trunk highway to recover the test. do. For the test items that should be tested at the same time as the host and the counterpart, the above method is the same as the above. However, there is a difference between executing and transmitting data as a message through a line using the maintenance channel (OPERATION & MAINTENANCE) which is NTM and CTM.

As described above, when the corresponding port is not active, the test is performed by releasing the trunk highway and connecting the ATU and the TCB using a separate temporary highway, as shown in FIG. Release the TCB and restore the trunk highway. In addition, the test of the method of transmitting from the self station node and receiving from the power station node such as DTMF, dial pulse, and level test (A / A) is transmitted from the self station node through ATU 4, then received from the power station node and is abnormal by ATU. The result is determined by sending the response message back to the host side so that the result can be reported.

According to the present invention described above, an inactive port can be tested using a separate temporary highway, and a specific test can be executed automatically while sending and receiving data in a message manner using a maintenance channel. Therefore, there is an advantage that the test efficiency is increased and the quality of the product is improved.
