Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a translator verification method, and more particularly to a translator verification method for an electronic switching system having a Centrex function or a plurality of area codes.

[Conventional technology]

The conventional translator verification method will be explained using an example of an electronic switching system having a Centrex function and a plurality of area codes as shown in the block diagram of FIG.

Subscriber port IA1. A2. A3. are subscriber circuits for Centrex that belong to different numbering plans, and the outgoing test line (hereinafter referred to as OTL) 22 is the subscriber circuit Al
, Bl belong to the same numbering plan 1. In electronic switching systems, there is a risk that calls may not be able to be connected if the translator provided in the main memory is changed incorrectly. Therefore, when changing the translator, first write new data to the test call translator in the translator 292 being changed, and if a test call can be made from 0TL22, the test call is made, and then the numbering plan 1. ．．
3 translator 293°294.295.

That is, by inputting a command, the maintainer of the electronic switching system first writes the station data to be changed into the test call translator in the translator 292 under change.
In order to test this data, the system test equipment (ST
0TL22 and network 26 using 21 (denoted as C)
The call was requested from the processor 24 to connect the call via the network accommodating the subscriber group of numbering plan 1.

At this time, the processor 24 successively retrieves the type of the outgoing line from the line memory 291, and if it is 0TL22, the test call is connected using the test call translator among the translators under change 292. Then, the maintenance person confirmed that the call originating from OTL22 was connected to the scheduled called subscriber circuit B1, and verified the normality of the changed translator data. For calls made from a line other than 0TL22 during this period,
Since the connection processing means 281 processes the call using the data before the change, which is stored in the general call translator in the translator 292 under change, in the unlikely event that the data after the change is stored in the test call translator. Even if the data in the call is incorrect, there will be no problem in connection processing of the call.

After verifying the changed data using the method described above, the maintainer of the electronic switching system inputs a command if the test call from 0TL22 is normal, and stores it in the test call translator using the station data change means 282. The changed data is transferred to the numbering plan 1 translator 293. Such control allows the numbering plan January translator 293 to be used for subsequent connections.

[Problem to be solved by the invention]

The conventional translator verification method described above is a verification method in which, when the type of the outgoing line is OTL, the test call is connected using the test call translator in the translator being changed, and the test call is verified by the maintenance personnel. there were. Therefore, the trasulator for a group of numbering plans with OTL is
You can verify the data after the change, but the trastors in the group of numbering plans without OTL cannot do so.
There is a problem in that it is necessary to take the risk of directly transferring unverified data to a translator for the corresponding numbering plan and using it for general call connection processing.

The object of the present invention is to provide a test auxiliary network that makes an interrupt connection to a subscriber circuit, and a test call information that writes test call information in the line memory of a corresponding general subscriber when an interrupt connection is made to the subscriber circuit. By providing an entry means and a connection processing means for connecting a call using a test call translator when test call information is entered, it is possible to establish a numbering plan corresponding to a unique numbering plan for each subscriber group. The purpose of the present invention is to provide a translator verification method that allows testing using updated data for all translated translators.

[Means to solve the problem]

The translator verification method of the present invention is a translator verification method for an electronic switching system having a test call translator and a general call translator and having a unique numbering plan for each subscriber group. A system test device that performs a test, a test auxiliary network that is controlled by the system test device and makes an interrupt connection to the subscriber circuit of a general subscriber, and when an interrupt connection is made to the subscriber circuit of the general subscriber. test call information entry means for writing test call information into the line memory of the general subscriber; and connection processing means for processing the call using the test call translator when the test call information is written. The configuration includes the following.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of one embodiment of the present invention.

The electronic switching system includes a system testing device (hereinafter referred to as STC as in the conventional example) 11 that tests the electronic switching system, and a central control unit (hereinafter referred to as CPU) that controls the system testing device and the electronic switching system. A test auxiliary network 12 which performs interrupt connection to the subscriber circuit of a general subscriber under the control of an interrupt connection processing means 181 provided in the CP (J18) and a subscriber circuit Al of the general subscriber provided in the CP A2. A test call information entry means 182 that writes the test call information into the general subscriber's line memory 191 provided in the main storage device 19 when an interrupt connection is made to A3; 191
If the test call information is entered in , the connection processing means 183 connects the call using the test call translator in the translator 192 under change, and after verifying the data after the change, the test call information from 5TC11 is sent. If the call is normal, a command is input from the maintenance terminal 174, and the changed data stored in the test call translator in the changing translator 192 is sent to the numbering plan translator 1.
Station data changing means 18 for posting to 93, 194, 195

Next, the operation will be explained.

When the maintainer of the electronic switching system changes the contents of the translator 193 for numbering plan 1, the maintainer of the electronic switching system
Input the station data change command from . The CPU 18 is
In this numbering plan 1 translator 193, an indication that the translator is being changed and the memory address of the translator 192 that is being changed are entered. The CPU 18 writes the data before the change to the general call translator of the translators under change 192 and the data after the change to the test call translator. Next, in order to verify the new data, the maintenance person enters the telephone number of the subscriber circuit A1 for general subscribers who use the changed numbering plan 1 into 5TC11, and
and the subscriber circuit A1 are connected by an auxiliary test network 12. At the same time, the CPU 18
2 is used to write in the line memory 191 of the subscriber circuit A1 that this is a test call that is currently being interrupted. 5TC11 then sends an off-hook signal to subscriber circuit A1 followed by the telephone number of terminating subscriber circuit B1. Call connection processing means 183 receives the telephone number from subscriber circuit A1 and learns that test call information is written in line memory 191 corresponding to subscriber circuit A1 and that it belongs to numbering plan 1.

Knowing this, the call connection processing means 183 translates the received telephone number into connection information using the number plan 1 translator 193, and since this translator 193 has an indication that it is being changed, it refers to the changing translator 192. do. Since the call connection processing means 183 already knows that this call is a test call, it uses a test call translator to translate the telephone number into connection information and connects the subscriber circuit A.
