DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a maintenance and operation center that monitors and tests switching equipment, and particularly relates to a monitoring and testing system for switching equipment where the scale and diversification of switching centers is expected to increase.

[Conventional technology]

Generally, in a communication system in which data is exchanged using a plurality of exchanges, a monitoring test system is used to monitor and test these exchanges in order to ensure smooth operation and high reliability of the system.

Normally, this type of monitoring test system is provided with a maintenance operation center, where monitoring test information from each exchange is transferred and collected as highway data. The monitoring test information collected at the maintenance operation center is distributed to a plurality of monitoring test devices according to type by a time switch device, and these devices perform various monitoring and testing of each exchange.

In such a conventional monitoring test system, each monitoring test device in the maintenance operation center is connected to a time switch device on a one-to-one basis via a highway. That is, at least one highway was assigned to each monitoring test device.

[Problems to be Solved by the Invention] In such conventional monitoring test systems, the time slot positions of monitoring test data on each highway are different for each monitoring test device, and there are unused slots on each highway. There were many time slots, so
Time slow/ ) could not be accommodated efficiently.

In addition, in conventional monitoring test systems, at least one highway was assigned to each monitoring test device, so as the number of exchanges subject to monitoring tests increases, the number of necessary monitoring tests increases. The number of devices and highways will also increase. Therefore, in preparation for future system expansion, it is necessary to equip the maintenance and operation center from the initial equipment stage with a time switch device that has a switching capacity that can accommodate the maximum number of switches that can be accommodated in the monitoring test system. However, it had the disadvantage of being uneconomical.

Furthermore, in the unlikely event that the number of highways becomes insufficient due to an increase in the number of switchboards, hardware changes may be made to increase the switching capacity of the time switch device, or multiple highways with many empty time slots may be It was necessary to change the software by consolidating it into a single system, which had the disadvantage of lacking flexibility.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a monitoring test system that can respond flexibly and economically to expansion of the system.

〔Example〕

Hereinafter, the present invention will be described in detail with reference to Examples.

FIG. 1 shows a monitoring test system in one embodiment of the present invention. In this figure, a maintenance operation center 11 is provided with a time switch device 12, and exchanges 14-1 to 14-1 of different models and functions are connected via a transmission line 13.
Connected to 4.

This time switch device 12 performs switching control according to maintenance and operation software, and sends and receives monitoring test data for each type to and from the exchange.

The maintenance and operation center 11 also includes monitoring test equipment 1 having highway multiplex circuits 15-1 to 15-5, respectively.
6-1 to 16-5 are provided, and the time switch device 12
Monitoring test data is sent and received for each data type. These monitoring test devices 16-1 to 16-5 are assigned to process monitoring test data of types E, A, C, and DSB, respectively. Of these, the highway multiplex circuit 15-1 of the first monitoring test device 16-1 is connected to the time switch device 12 via the monitoring test highway 17-1, and the second monitoring test highway 17-2 is connected to the time switch device 12 via the monitoring test highway 17-1. It is connected to the monitoring test device 16-2. Furthermore, this second monitoring test device 16-
The second highway multiplex circuit 15-2 is connected to a third monitoring test device 16-3 by a monitoring test highway 17-3.

Further, the no\way multiplex circuit 15-4 of the fourth monitoring test device 16-4 is connected to the time switch device 12 via the monitoring test/'% way 174, and is also connected to the time switch device 12 via the monitoring test highway A and A. Fifth monitoring test device 16-

FIG. 2 shows the time slot structure of the monitoring test highways 17-1 to 17-5.

As shown in this figure, each of the supervisory test highways of time switch device 12 has 32 time slots. Each time slot corresponds to one byte of data. These 32 time slots consist of 6 blocks 21 to 26 each consisting of 5 time slots,
It is composed of a control code time slot 27 and an unused time slot 28. Among these, the control time slot 27 can be used to indicate the number of time slots to be used. In other words, the values "0" and "1" of the first to sixth bits of the 8 bits of the control code excluding 2 unused bits correspond to the "usage state" and "usage state" of the 1st to 6th blocks, respectively. It corresponds to the “vacant state”.

Here, it is assumed that each piece of monitoring test data consists of 5 bytes, and each piece of monitoring test data is allocated to one block.

The operation of the monitoring test system configured as above will be explained with reference to FIGS. 3 and 4.

Here, the operation when monitoring test data is transferred from the monitoring test device to each exchange will be explained.

First, the highway multiplex circuit 153 of the monitoring test device 16-3 located at the farthest end of the monitoring test highway transfers its own monitoring test data (C1C3, Cs) to the first
- After allocating to the third blocks 21 to 23 (FIG. 2e), the first to third bits of the control code (FIG. 2f) are set to "1". Then, the highway multiplex circuit 15-2 of the monitoring test device 16-2 sends these to the monitoring test device 16-2 via the monitoring test way 17-3 (step in FIG. 3) and checks the control code. Then, a bit set to "0" is detected (step ■).

In this case, since the 4th to 6th bits are “0” (the 2nd

1” (d in the same figure), and then sends it to the monitoring test device 16-1 via the monitoring test highway 17-2 (
Step ■).

The highway multiplex circuit 15-1 of the monitoring test device 16-1 checks the control code and detects a bit set to "0" (step 2).

In this case, since the 6th bit is “0” (Fig. 2 d)
, because it is recognized that the sixth block 26 is empty,

Then, after setting the 6th bit of the control code to "1" (step 2, FIG. 2b), it is sent to the time switch device 12 via the monitoring test highway 17-1 (
Step ■). In the end, the time switch device 12 receives the monitoring test data (A+, A4, CI, C3, C) with all 6 bits of the control code set to "1".

.

Similarly, the highway multiplex circuit 15-5 of the monitoring test device 16-5 sends its own monitoring test data (B
, B2 B3, B-) in the first to fourth blocks 21
24 (FIG. 2 I), and set the first to fourth bits of the control code to "1" (FIG. 2). Then, this is sent to the monitoring test device 16-4 via the monitoring test highway 17-5 (step 4 in FIG. 4).

The highway multiplex circuit 15-4 of the monitoring test device 1G-4 checks the control code and detects a bit set to 0'' (step 2).

In this case, since the 5th and 6th bits are “0” (the 2nd
]), it recognizes that the fifth and sixth blocks 25 and 26 are empty, so it allocates its own monitoring test data (D,) to the fifth block (see the figure). g). Then, after setting the fifth bit of the control code to "1" (step ■, h in Figure 2), monitoring test 7

B4, Da) will be transferred (Fig. 2 g, f)
.

The time switch device 12 distributes and transfers these monitoring test data to the exchanges 14-1 to 14-4 according to maintenance and operation software prepared in advance.

In addition, maintenance operation center 1 is connected from exchanges 14-1 to 14-4.
The transfer of monitoring test data to 1 is performed in the reverse order of the process described above. That is, various types of monitoring test data from the exchange side are classified by data type by the time switch device 12 and sent to the corresponding monitoring test way. Then, each monitoring test device takes in and processes the monitoring test data of the type corresponding to its own device while referring to the control code.

In this way, according to this embodiment, the time switch device 12
and five monitoring test devices 16-1 to 16-5 are connected via two highways, and transfer control of monitoring test data is performed.

〔Effect of the invention〕

As explained above, according to the inventions recited in claims 1 and 2, the monitoring test information is time-division multiplexed and transmitted on the highway connecting a plurality of monitoring test devices, and the time slot position and Since the required number is made variable, the number of highways can be reduced. In addition, even if monitoring test equipment is added due to the increase in types of monitoring test information due to the addition of switchboards, this can be connected to existing highways, so there is no need to increase the number of highways connected to the time switch equipment. do not have.

Therefore, it is possible to upgrade the system within the switch capacity of the existing time switch device.

Therefore, it is possible to respond flexibly and economically to expansion of the system.

Further, in the invention as claimed in claim 3, when the monitoring test information is sent out on the highway, control information indicating the position and required number of time slots is multiplexed together and sent. This has the advantage that transmission and reception can be performed reliably and easily.
