Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention provides a plurality of electric currents f'9. The present invention relates to a multi-unit system configured with exchange units.

[Prior Art] In a conventional multiple unit configuration system, a plurality of electronic switching units each have an independent configuration to form a network.
-It was.

[Problem to be solved by the invention 1] The conventional multiple cornice structure system with two series
Since the constituent electronic exchange units are independent, I.
When Ushitsuk is lopsided, line usage increases due to detours1
- There was a problem in that the effective use of one line was hindered.

An object of the present invention is to provide a multi-unit configuration system that solves the above-mentioned problems.

[Means to solve the problem]

The basic configuration of the multiple unit configuration system according to the present invention is a multiple unit configuration system (1,:) consisting of a plurality of electronic exchange units).
a communication path switch that accommodates and connects the communication paths that are accommodated and connected to each, and a control processor that controls the communication path switch by transmitting and receiving information to connect to the Brossena of the electronic exchange units 1 to 1 through a high-speed bus. @mail the exchange unit between unit 1 and having the unit.

One specific configuration of the electronic switching unit described in this basic configuration is that each of the four electronic switching units includes a connection information memory that receives and stores the connection status of the communication path between the units and the inter-unit switching unit; Notification signal of 99 instances of #W occurrence in drive prohibition state (inter-unit exchange unit).The unit receives this release signal from the unit-to-unit exchange unit and restricts or releases the restriction on the inter-unit connection of the electronic exchange unit. In addition, if the conditions for line release are met, unit
and a processor that reads the connection status between the units from the connection information and the memory, performs release processing, and notifies the inter-unit exchange unit of the completion of processing.

In addition, the specific configuration of the inter-unit exchange unit described in the basic configuration is to send a drive monitoring status of the inter-unit exchange unit, such as a failure notification signal or a cancellation signal to the electronic exchange unit. At the same time, it has a control processor that notifies all electronic exchange units I- of the notification of completion of release processing when it is received from electronic exchange unit 1=-.

〔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 flowchart showing an example of the main operation procedure according to FIG.

As shown in the figure, a plurality of electronic exchange units 10 are connected to an inter-unit exchange unit 20 by a communication path 31 and a high-speed bus 32 using an optical cable.

The electronic exchange unit 10 is a communication path switch 11゜processor]2. and a connection information memory 13, and the inter-unit exchange unit 20 has a communication path switch 21 and a control processor 22.

The communication path switch 11 functions under the control of the processor 12. The processor 12 mainly has a normal exchange function, and also serves as a control processor 2 for the inter-unit exchange unit 2O.
It also has the function of exchanging information between units I and 2 by exchanging information with each other.

Connection information memory 13 is electronic exchange unit] 0 is unit
=Memorize the status of connection with the inter-exchange unit 20.

The communication path switch 21 functions under the control of the control processor 22, and the communication path 31 to be accommodated and connected is connected to the communication path switch 11 of each electronic switching unit 10. The control processor 22 sends and receives information to and from the communication path switch 21, and also communicates with each electronic switching unit via the high-speed bus 32.
is connected to the processor 12 of the computer.

Although normal switching functions can be performed with the above configuration, when connection restrictions are enforced due to a failure in the unit-to-unit exchange unit, when the connection restriction is lifted and the unit-to-unit exchange unit is restarted, the lines that have been in use up to that point are A release process is required, which prevents errors in stored information.

This will be explained with reference to FIG. 2 and FIG. 1 together. Inter-unit exchange When a failure occurs in unit 2o,
The control processor 22 detects the occurrence of a failure (101) and
Drive prohibition via express bus 32, electronic exchange unit 1
0 processor 12 is notified (102). The processor 12 that receives the driving prohibition (103) regulates inter-unit connections (104). After notifying drive prohibition in step 102, the control processor 22 notifies the processor 12 via the express bus 32 of the cancellation of the drive prohibition upon recognizing recovery from the failure (105). Drive monitoring cancellation received (1
06), the processor 12 releases the restriction on connections between units (107)L, and stores the line connection status in the connection information memory 1.
Adjust in step 3 (108), it is necessary to release the line by adjusting (108).
109), the processor 12 performs line release processing (1
10), the end of the process is notified to the control processor 22 via the high-speed bus 32 (111). processor 2
2 receives the completion of line processing from all the electronic switching units 10 (112), and when it is L, notifies the processors 12 of all the electronic switching units 10 of the completion of all processing (113). The processor 12 receives the notification of completion of all processing (114
) to start the inter-unit connection.

In other words, the connection between the units is restarted after returning the line connection state to almost its initial state.

〔Effect of the invention〕

As described above, the present invention is configured such that each of the communication path switches and processors of a plurality of electronic exchange units is connected to each of the communication path switches and control processor of an inter-unit exchange unit by a communication path and a high-speed bus, respectively. By doing so, there is an effect that the line can be used efficiently based on the line usage status with each electronic exchange unit to which the inter-unit exchange unit connects.
