DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone exchange such as a main private branch exchange (PBX), and more particularly to a telephone test, that is, an office line test.

[0002]

2. Description of the Related Art FIG. 4 is a block diagram showing a conventional telephone exchange apparatus for performing a conventional outgoing / incoming call test (offline test) to / from an office line by artificial operation. FIG.
, 1a and 1b are the same telephone terminal, 1a is outgoing,
Reference numeral 1b denotes an incoming call for explanation, and reference numeral 2 denotes a telephone terminal 1.
a transmission processing unit 3 for processing a series of PB signals; 31 a PB sender for converting a telephone number into a PB signal; 32 a PB receiver for translating a received PB signal into numerals; is there.

[0003] Reference numerals 41 and 42 denote office lines necessary for connection to the outside. Here, dial-in lines for which the importance of the test is high are actually comprised of several tens of lines. 4 is a public network accommodating office lines,
5 processes an incoming call received from the public network 4, and
An incoming call processing unit 6 connects a call to b, and a telephone switching unit 6 connects and accommodates these.

[0004] Next, the operation will be described. When performing the outgoing and incoming tests of the office lines 41 and 42 connected to the telephone exchange device 6, the maintenance person must use the outside line assigned to the telephone terminal 1b from the telephone terminal 1a. Dial a number. The dial is processed by the PB processing unit 3 and transmitted from the office line 41.
The public network 4 having received the call prompts an incoming call to the office line 42 from the received dial.

When the incoming call is received, the incoming call processing unit 5 calls the telephone terminal 1b, and another maintenance person responds to the ringing sound so that the telephone terminal 1a and the telephone terminal 1b can communicate via the public network. Reach. After the call, both maintainers will be able to use the telephone terminal 1a,
The handset of 1b is taken down, and the test is finished.

[0006]

The line switching test of the conventional telephone exchange has been performed as described above. However, in the telephone exchange, the connection to the public network is established by the user of the internal telephone terminal. This is the most important function to communicate. When a failure occurs in this function, it is necessary to carry out a function test in a short period such as every day so that the maintenance person can quickly find out. However, in the conventional function test, as described above, the maintenance person needs to actually make a call from a local telephone terminal. In other words, maintainers visit the site every day,
It is virtually impossible.

[0007] For this reason, the maintenance person cannot detect the failure at an early stage, and the failure is noticed by the user who actually uses the telephone terminal. In particular, in the case of an incoming call from the public network, a third party who calls from the outside may feel irritated in a state of being unable to make a number of calls and complain to the insider by some means. Also, the third party referred to here is often an unspecified number of customers from the insider's point of view, and it is delayed for the insider to notice the occurrence of the failure. Therefore, there is a problem that when the trouble is notified to the maintenance person, the trouble has continued for a long time, and the damage has swelled significantly.

Further, when the office line is a dial-in line, a large number of lines such as tens of lines are collectively managed in a public network. For this reason, a problem often occurs not only in one line but in all tens of lines, causing a problem that causes a great obstacle to a user.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems. By automatically performing this test, an automatic line-line test mechanism that can detect a line-line fault quickly without relying on humans is provided. The purpose of the present invention is to provide a telephone exchange device provided.

[0013]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiment 1 FIG. 1 is a block diagram showing a telephone exchange provided with a local line automatic test mechanism according to an embodiment of the present invention. In FIG. 1, reference numerals 2 to 5 are the same as those in the related art, and a description thereof is omitted. Also, the telephone terminal 1a,
1b also exists, but is omitted because it is unnecessary for operation. 6a is a telephone exchange provided with an automatic line test system according to the present invention,
T is a local line automatic test mechanism.

Reference numeral 7 denotes test control means for controlling the automatic line test according to the present invention. Reference numeral 8 denotes test processing means for executing a test in accordance with an instruction from the test control means 7 and making a judgment. Automatic calling means for performing an operation of making a call to the office line 41 as in the terminal 1a. Reference numeral 10 is also an automatic call receiving means for receiving an incoming call from the office line 42, which is also equivalent to the conventional telephone terminal 1b. Is a recording means for recording and storing a series of test results and the like, and 12 is a known error processing means for outputting an alarm when an abnormality occurs in the telephone exchange 6a.

Note that during the local line automatic test mechanism T, the test control means 7, test processing means 8, automatic calling means 9, automatic call receiving means 1
The 0 and error processing means 12 can be constituted by a computer operating according to a built-in program, for example, and the storage means 11 can be constituted by a memory. ,

FIG. 2 is a flowchart showing an example of the operation of the local station automatic test mechanism T. Step S1a indicated by a dashed line is relevant only in the second embodiment.

Next, the operation will be described. A maintenance person pre-registers (for example, in the storage means 11) by the test control means 7 in FIG.
The test is started according to the test date and time set (step S
1) The test is performed by the test processing means 8. After performing the test, the automatic calling means 9 performs an operation of dialing an external line number allocated exclusively for the test and making a telephone call, like the telephone terminal 1a described in the operation of the prior art (step S).
2). After that, as in the conventional operation, the central office 4
2 and the incoming call processing unit 5 calls the automatic call receiving means 10. The automatic call receiving means 10 automatically responds to the call, and reaches a telephone call with the automatic calling means 9. If there is no call, there is a failure somewhere on the office line (step S3).

When the test processing means 8 detects that the call has been reached, the arbitrary number is converted into a PB sound by the PB sender 31,
This PB sound is transmitted in the same manner as the voice (step S4). P
The B sound arrives at the test processing means 8 via the public network 4 and the automatic call receiving means 10. The arriving PB sound is digit-translated by the PB receiver 32, collated with the previously issued numeral, and the result is output to the test control means 7 (step S5).

Upon receiving the test result, the test control unit 7 outputs the test result to the recording unit 11 in accordance with the test start date and time. The recording unit 11 accumulates and records the received recording as needed (step S6). The maintenance person can know the test result by confirming this record, but if a series of tests cannot be completed normally due to some failure in the telephone exchange, office line, public network, etc. If the received PBs do not match (steps S3 and S7), the error processing means 12 generates a known alarm (step S8).

As described above, the present invention is a technique effective for a dial-in line which is greatly damaged in the event of a failure among office lines, and tests one external line number assigned for testing as a sample, thereby obtaining a dial-in line. This is to determine the possibility of failure occurrence in all cases. This automatic test automatically performs the same test contents as the conventional manual telephone call test according to a test program registered in advance by the maintenance person without the maintenance person working on site as in the prior art. Therefore, it is possible to carry out a test such as a daily test which has not been conventionally performed because of difficulty. In addition, if a failure is detected in this test, an alarm output is immediately generated, so that the maintenance person can quickly know the failure without delaying notice of the failure, and can be used by telephone terminal users and third parties. Complaints can be minimized.

Embodiment 2 FIG. FIG. 3 is a block diagram showing a telephone exchange provided with a local line automatic test mechanism according to another embodiment of the present invention. The difference from the first embodiment shown in FIG. 1 is that a call path switching means 81 for changing the telephone terminal number of the destination is provided in the test processing means 8, and the other parts are basically the same. .

Next, the operation will be described. In the first embodiment, the test is performed using the external line number assigned exclusively for the test. However, in the present embodiment, the external line number dedicated to the test is not required, The outside line number used by the user is used as a test only for a short time, such as about 10 seconds, in a time zone when the user is considered to have left, such as at midnight. In the operation, a maintenance person registers in advance the test date and time for the outside line number of the user who performs the test in the test control means 7.
(For example, it is stored in the storage unit 11). At this time, the set time is midnight or early morning when the user is expected to leave.

At the set date and time (step S1), the newly arranged communication path switching means 81 switches the destination of the external line number from the user's telephone terminal to the automatic call receiving means 10 (step S1a). The automatic calling means 9 dials the outside line number of the user, and thereafter performs a test as in the first embodiment. When the test is completed, the previously switched outside line number is switched back from the automatic call receiving means 10 to the telephone terminal. Similarly, other outside line numbers are switched and executed at a designated time.

In the first embodiment, the test is performed with the external line number dedicated to the test as one sample in all dial-in lines. For this reason, it is effective for malfunctions of all dial-in lines, but is not effective for finding malfunctions of individual lines. However, in the second embodiment, the test can be performed for all the external line numbers using the external line numbers actually used by the user, which is also effective for the trouble of each line. Furthermore, since it is possible to correspond to individual lines, the same effect can be obtained not only for a dial-in line managed collectively but also for a general line. In addition, there is no need to specially contract an outside line number for a test with the public network, and the cost can be reduced.

[0025]

As described above, according to the present invention, a test date registered as a sample of one outside line number assigned for a test is a technique effective for a dial-in line which is greatly damaged in the event of a failure even in a local line. The automatic telephone line test, that is, the local line automatic test mechanism that automatically performs the local line test, can determine the possibility of failure occurrence in all dial-in lines,
It is possible to automatically execute the same test content as the conventional manual telephone call test according to a test program registered in advance by the maintenance person without the conventional maintenance person working on site. Therefore, it is possible to carry out a test such as a daily test which has not been conventionally performed because it is difficult, and if a failure is recognized in this test, an alarm output is immediately generated, so that it is delayed to notice the failure. The maintenance person can immediately know the failure without any trouble, and the complaint of the telephone terminal user or a third party can be minimized.

Further, in another embodiment, it is possible to carry out a test for all the external line numbers using the external line numbers actually used by the user, which is effective also for troubles of individual lines. The effect is obtained. Furthermore, since it is possible to correspond to individual lines, the same effect can be obtained not only for a dial-in line managed collectively but also for a general line. In addition, there is no need to specially contract an outside line number for a test with a public network, which has an effect of reducing costs.
