The present invention relates to an inter-station relay line automatic test method capable of automatically performing an installation verification test for a relay line installed between an Altu (R2) switching station using the Altu (R2) signaling method.

In general, in the case of installing relay cables between exchanges, it was very time consuming to check the installation of the relay cables because the operator manually performed the installation verification test for the relay cables. In particular, in the case of a large number of relay lines installed, there is a problem that a lot of inconvenience comes when the operator performs the installation confirmation test manually.

An example of a conventional trunk line automatic test apparatus devised to solve this problem will be described with reference to FIG. 1.

As described above, in order to automatically test a relay line, a relay line automatic test apparatus which is configured outside of an electronic switchgear is separately required, and accordingly, a lot of time and cost are required, and there is a problem in that the number of relay lines to be tested cannot be adjusted. there was.

The present invention devised to solve the above problems, in the case of installing a relay line applying the Alnu (R2) signal system between exchanges, without using a separate relay line automatic test device configured externally, Alto (R2) signal The purpose of this service is to provide a method for automatic test of trunk line between stations that allows the operator to automatically perform the test of relay line installation using the characteristics of the method.

That is, when the R2 signaling method is applied between switching stations to which the relay line is connected, the R2 signaling method performs R2 signaling by using the line of the relay line through which voice / non-voice data is transmitted, and thus the relay line installed according to whether the R2 signaling is normally terminated. You can check whether there are any abnormalities, and if you perform R2 signaling on all the lines of the relay line using the numbers specified between the exchanges for the installation confirmation test, you can automatically test whether the relay line is installed with the conventional R2 equipment without burdening additional equipment. The purpose is to provide a method for automatic test of trunk line between stations.

In order to achieve the above object, the present invention, in the relay station automatic test method between trunks applied to the integrated telecommunications network switching period connected to the relay line to which the Alto (R2) signaling method is applied, when the relay line test request is received, A first step of occupying the line; As the Al2 (R2) signaling with the counterpart exchange is normally performed by performing Al2 (R2) signaling on the line occupied by connecting the Al2 (R2) signaling equipment, the connection of the Al2 (R2) signaling equipment is established. A second step of releasing; A third step of connecting a tone receiver to an occupied line and receiving a test tone from the counterpart exchange to confirm that the relay line is normally installed; A fourth step of recording the relay line test result between the Alto (R2) stations after releasing the occupied line; And a fifth step of notifying the operator of the results of the relay line test between Alto stations after repeating each step for all the lines to be tested.

Hereinafter, with reference to the accompanying drawings will be described an embodiment according to the present invention;

3 is a flow chart of an embodiment showing the processing procedure of the automatic trunk line test method according to the present invention.

Upon receipt of the operator's relay line test request through the operator terminal (31), the exchange transmits the occupancy signal to the counterpart installed with the test relay line and receives the occupancy response to occupy the trunk of the relay line requiring testing (32, 33). Connect signaling equipment.

Using the subscriber number assigned for the relay line installation verification test as the called party number and the type of calling subscriber required for R2 signaling as a maintenance device, R2 signaling is performed on the occupied circuit (34). If the R2 signaling with the counterpart exchange is performed normally (35), the R2 signaling equipment is disconnected and the receiver of the test tone is connected to the occupied circuit.

When the test tone is received from the counterpart exchange within a certain time (36), it can be determined that the installation of the relay line is normally performed. Afterwards, the counterpart exchange transmits an omnidirectional recovery signal (CLF: Clear Forward) to notify the release of the occupied line (37), and upon receipt of the release completion signal (RLG: Release Guard) from the counterpart exchange, releases the occupied line. (38). Subsequently, upon completion of the installation verification test for all circuits installed between the two exchanges, the operator is notified of the relay line test results between the R2 stations (39).

4A and 4B are detailed flowcharts of the method for automatic test of trunk line trunking according to the present invention.

When the operator receives a request for confirmation of installation of a relay line installed at the exchange (41), the operator occupies the first line of the relay line connected to the counterpart exchange (42).

If the test is completed, the test results are output to the operator and the repeater installation verification test is completed (61).

When the line is occupied (43), after connecting the R2 equipment to the corresponding line (44), the subscriber number assigned for the relay line installation confirmation test is called as the called party number, and the type of outgoing subscriber required for R2 signaling is maintained. R2 signaling with the counterpart exchange is performed (45).

At this time, if the R2 signaling with the counterpart exchange fails (46), after disconnecting the R2 signaling equipment (47), the circuit occupied by transmitting an omnidirectional recovery signal (CLF: Clear Forward) to the counterpart exchange. Release the occupied line (57), record the test results so far (58), and verify that the installation verification test has been performed for all the lines of the installed repeating line (59). If the test is not completed, the next line is occupied (60) and the process after the occupancy is continued. If the test is completed, the test results are output to the operator and the repeater installation verification test is completed (61).

If the R2 signaling with the counterpart exchange is successful (46), disconnect the R2 signaling equipment (48) and after connecting the tone receiver to the occupied line to receive the test tone from the counterpart exchange (49). A timer for waiting for the test tone is driven (50) and enters the test tone standby state.

If the test tone is not received from the counterpart exchange for a certain time, and the timer expires (51), the tone receiver is disconnected (52), and then the omni-directional recovery signal (CLF: Clear Forward) is transmitted to the counterpart exchange. Release the occupied line (57), record the test results so far (58), and verify that the installation verification test has been performed for all the lines of the installed repeating line (59). If the test is not completed, the next line is occupied (60) and the process after the occupancy is continued. If the test is completed, the test results are output to the operator and the repeater installation verification test is completed (61).

When a test tone is received from the counterpart exchange within a predetermined time (53), the timer stops driving (54), and after the tone receiver is disconnected (55), a forward recovery signal (CLF: clear forward) is sent to the counterpart exchange. Send a notification to release the occupied line (56), release the occupied line (57), record the results of the tests performed so far (58), and verify that the installation verification test was performed on all the lines of the (59) If the test is not complete, then occupy the next line (60) and continue the process after occupancy. If the test is completed, the test results are output to the operator and the repeater installation verification test is completed (61).
