Conventionally, this type of switch monitoring test system has a switch interface section provided for each switch model or exchange unit, and each of these switch interface sections is connected by a single highway, and monitor test information from each switch is aggregated. It was equipped with a switch section, and the system was controlled by a predetermined program, making it possible to monitor, test, and operate multiple exchanges.

[Problem to be solved by the invention]

In such a conventional switching equipment monitoring test system, as mentioned above, a switching equipment interface unit is provided for each switching equipment model and replacement unit, and these interface units and switch units are connected by one highway. The capacity of the switch unit, that is, the number of highways, determines the number of exchanges that can be accommodated in the monitoring test system, and can be used from small-scale stations to large-scale stations with multiple exchange units installed. In order to be able to respond flexibly, the switch section must be highly expandable. If the capacity of the switch section is insufficient and a new highway is to be added, major changes to the hardware and software will be required, so it is necessary to set the maximum number of highways large in advance to avoid a capacity shortage. There is. Therefore, conventional systems are extremely expensive.

Note that if there is an empty time slot on the highway, it is possible to insert monitoring test information of a new exchange into the empty time slot, but this requires a significant addition of hardware.

In addition, since the exchange interface section is transparently connected to the switch section depending on the exchange model and replacement unit, the program that controls the system must also execute control corresponding to each exchange model and replacement unit. be. Therefore, the program is complicated and difficult to have a general-purpose configuration, which is another cause of lowering the economic efficiency and flexibility of the system.

The purpose of the present invention is to solve these problems and provide a switching equipment monitoring and testing system that is highly economical regardless of the scale of the switching office and can flexibly accommodate various functions and models of switching equipment. .

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

FIG. 1 is a block diagram showing an embodiment of an exchange monitoring and testing system according to the present invention. This system consists of an exchange interface unit 2 that is provided for each exchange type and exchange unit, and that collects a plurality of pieces of monitoring test information from each exchange 5.
and a switch unit 1 which is connected to each of these exchange interface units 2 by one highway 4 and aggregates the monitoring test information, and each exchange interface unit 2 once stores the monitoring test information from the exchange 5. An elastic memory 6 for reading and synchronously sending out to the highway 4, and data indicating the timing of writing monitoring test information to this elastic memory 6 and reading monitoring test information from the elastic memory 6 are stored. and a time slot information editing memory 7. The interface section 2 also includes an expansion exchange interface section 8 for handling monitoring test information and an increase in the number of replacement units. A control section 3 connected to the switch section 1 is for controlling the system based on a predetermined program.

Next, the operation will be explained. When the exchange interface section 2 collects a plurality of pieces of monitoring test information from the exchange 5, the exchange interface section 2 stores the information in the memory 7.
Based on the data stored in the elastic memory 6, the information is temporarily stored in the elastic memory 6 at a predetermined timing. Thereafter, based on the data stored in the memory 7, the monitoring test information is read out at a predetermined timing synchronized with the timing of the highway 4, inserted into the time slot of the highway 4, and sent to the switch section 1. Based on the control of the control unit 3, the switch unit 1 connects the highway 4 from each exchange interface unit 2 at respective timings.
It receives and receives monitoring test information sent through the network and centralizes it to enable monitoring, testing, and operation of switching equipment.

When the monitoring test information or the number of replacement units increases, the monitoring test information is input into the memory 6 through the expansion exchange interface unit 8. And time slot information II f
, by changing the data in the H collection memory 7, the time slot position of the highway 4 is shifted or replaced,
Insert new monitoring test information into an empty time slot.

Therefore, in this system, by simply changing the data in the memory 7, it is possible to use empty slots to cope with an increase in the number of exchanges at low cost.In addition, by editing the same time slots, various functions and models of exchanges can be adjusted. can respond flexibly.

In this system, one exchange interface unit can collect monitoring test information from multiple exchanges, so the program in the control unit 3 that controls the system executes control corresponding to each exchange model and exchange unit. There is no need to do this, and as a result, the program can have a simple and versatile configuration.

〔Effect of the invention〕

As described above, the present invention provides an exchange that includes an exchange interface section that collects monitoring test information from an exchange, and a switch section that is connected to each of these exchange interface sections by l-tree highways and that aggregates the monitoring test information. In the monitoring test system, the exchange interface section includes an elastic memory for storing and reading the monitoring test information from the exchange, synchronously connecting it, and transmitting it to the highway, and a function for reading the monitoring test information from the elastic memory. It is equipped with a time slot information editing memory that stores data indicating timing.

Therefore, in the exchange monitoring test system of the present invention, when the monitoring test information or the number of exchange units increases, new monitoring test information is written in the elastic memory, and data in the time slot information editing memory is changed. By doing so, the time slot position of the highway can be shifted or replaced, and new monitoring test information can be inserted into the vacant slot of the highway at low cost. Furthermore, by editing similar time slots, it is possible to flexibly accommodate various functions and models of exchanges.
