Abstract

PURPOSE:To conduct line test without provision of a line test additional installation by for each kind of lines by providing a test use call control signal data whose signal system, signal procedure and content of signal is freely defined in a maintenance operation management processor. CONSTITUTION:A call processing processor 2 handles a call control signal data sent from a maintenance operation management processor 1 as a test call to implement the call connection operation. In this case, a station subscriber data required for the call connection operation is given to a reference selection section 24 and an in-system bus 5 to reference a test station subscriber data management section 11. A call control signal received by the call processing processor 2 through a tested signal line 4 is outputted to a maintenance operation terminal equipment 3 as a command reply by a pattern output to confirm the normality or the like. Thus, the line is tested without provision of the additional line test installation different from the kind of lines.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a switching system line testing method, and more particularly, to a switching system line testing method, in which test call control signal data and a test station/station concerning the line under test are stored in a maintenance operation management processor in a switching system. This invention relates to a switching system line testing method in which subscriber data is kept separate from station/subscriber data in the currently used call processing processor.

[Conventional technology]

Conventionally, this type of switching system line testing method has been equipped with a line testing device within the switching system and a mechanism for starting the test from a dedicated test terminal or measuring device corresponding to the type of line. -Stations to be referred to during general calls and tests.
Subscriber data was mixed and created in one station/subscriber data section.

[Problem to be solved by the invention]

The conventional switching system line testing method described above has the disadvantage that the amount of equipment for the switching system becomes large because it is necessary to have different auxiliary line testing equipment for each type of line. In addition, because test and current station and subscriber data were mixed together, the types of station and loud sound data that could be changed for testing were limited, and the degree of freedom in test patterns was limited. 6 [Means for Solving the Problem] The switching system line testing method of the present invention stores test station/subscriber data and test call control signal data to be transmitted to the line under test. A switching system line test method in which a maintenance operation management processor controlled by a call processing processor controls call connections during a test by transmitting and receiving test call control signals to and from a call processing processor, the call processing control within the call processing processor The part is characterized in that the normality of the line under test is verified by making a call connection with reference to the test station/subscriber data in the maintenance and operation management processor during the test.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention, and FIG. 2 is a flow diagram showing an example of the line test procedure in FIG. 1.

In FIG. 1, this embodiment is a maintenance operation management processor 1.
and a call processing processor connected via an intrasystem bus system. The maintenance operation management processor 1 includes a maintenance operation terminal 3 connected via a maintenance operation terminal communication line 31, and the maintenance operation management processor 1 includes a test station/subscriber data management section 111, a line test control section 12, and a test call control signal data management section 13. The call processing processor 2 has a working station/subscriber data management section 21 . Call processing control unit 22. It has a signal transmitter/receiver 23 and a reference selector 24 that transmit and receive signals to and from the signal line 4 .

Next, the operation of this embodiment will be explained.

When the need for a line test arises due to factors such as a failure in a certain subscriber line or relay line, or a change in the expansion 7 local station, the station/subscriber data related to these lines is changed (step 101). In this case, the maintenance operation terminal 3 sends the line test control unit 1 to the test station/subscriber data management unit 11.
Make a change request via 2. Next, data describing the test call control signal procedure and signal content for creating a call connection using these lines is created, and the data is sent to the maintenance operation terminal 3.
Similarly, a change request is made to the test call control signal data management unit 13 (step 102). Examples of call control signals include the D channel signaling system recommended as an international standard, No. 7 ISDN User Vert (I 5UP), and the like. Step 103) When the maintenance operation terminal 3 is activated during a test, the line test control unit 12 reads the data describing the call control procedure from the test call control signal data management unit 13, and then translates it as a call control signal. and the call processing controller 2 in the call processing processor 2 through the system bus 5.
2. The signal procedure can control transmission and reception,
Transmission and reception with the call processing processor are repeated in sequence according to this procedure data.

The call processing processor 2 handles the call control return signal data sent from the maintenance operation management processor 1 as a test and performs a call connection operation. In this case, the station/subscriber data necessary for the call connection operation is stored in the reference selection section. 24, refer to the test station/subscriber data management unit 11 through the system bus 5. The call control signal received by the call processing processor 2 through the signal line under test 4 is sent to the call processing controller 22 via the signal transmitting/receiving section 23.
The event is sent to the event server and used as an event for call connection operation.
At the same time, it is also passed to the maintenance and operation management processor 1 through the system bus 5, and becomes an input event in the procedure control of the line test control section 12.

This signal is also output on the screen as a command response to the maintenance and operation terminal 3 via the maintenance and operation terminal communication line 31.

In determining the test result (step 104), the normality of the test result is confirmed based on the call control signal output on the screen.

If the test conditions for the test signal and station/subscriber data are changed and the test is started again, the process starts from step 101 again.

〔Effect of the invention〕

As explained above, since the present invention has test call control signal data in which the signal system, signal procedure, and signal content can be freely defined in the maintenance and operation management processor, it is necessary to prepare line test incidental equipment for each line type. It has the effect of being able to perform line tests without using it.

Additionally, during testing, instead of referring to the current station/subscriber data section, you can freely create station/subscriber data that corresponds to the test pattern, without affecting general calls. This has the effect of increasing the degree of freedom in exam content.
