Abstract

PURPOSE:To decrease the required time by constituting n-system of optical bus systems having a program load processing so as to apply simultaneous loading in applying initial program loading to all data communication control processors. CONSTITUTION:Duplicated '0' system optical bus 10 and '1' system optical bus 11, file control processors FCP (FCP020, FCP121) applying the program load control connected to the buses and data communication control processors CCP (CCP030, CCP131-CCP737) constitute a decentralized control type exchange. In applying simultaneous program loading to all the CCPs, the '0' system optical bus 10 is drawn to the processors FCP020, CCP131, CCP333, CCP535 and CCP737 and the '1' system optical bus 11 is drawn to the remaining FCPs and CCPs to constitute the independent optical bus system. The FCP020, FCP121 have a file required each initial program load, the initial program load is started at the same time and the program is loaded to all the CCPs. Thus, the required time is reduced.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an initial program loading system, and in particular to a distributed control switching device in which a control processor that loads a program and a communication control processor are connected via a multiplexed optical bus. This article relates to the initial program loading method in 8.

[Conventional technology]

Conventionally, this type of switching device has been used to load the initial program to all processors at the same time, and when the switching function is activated.
Consisting of an optical bus that always serves as one act (ACT), there is one control processor in the optical path system that serves as the act that controls program loading. I was doing the program 4th.

[Problem that the invention seeks to solve]

The conventional initial program loading method described above has a configuration in which one control processor in charge of program loading loads programs to all other communication control processors via one optical bus, so all processors are sequentially loaded with the initial program. When loading, there is a drawback that as the number of communication control processors existing in one system increases, the time required to load the initial program to all processors increases.

[Means for solving problems]

The initial program load method of the present invention is implemented in a distributed control switching device in which a plurality of data communication control processors and a plurality of program load control processors are connected by an n-layered optical bus.

When initial program loading is performed on all the data communication control processors at once, an n-based original bus system having one program load control processor is configured, and a plurality of the data communication control processors connected to each optical bus are configured. Initial program loading to the communication control processor is performed at the same time by the original bus system of the n series.

〔Effect of the invention〕

As explained above, the present invention is applicable to all data communication control processors of an n-multiplexed optical path system when the initial program is loaded at the same time.

By connecting a program load control processor that controls program loading to each system optical bus system, and starting program loading simultaneously by all n system program load control processors, data communication that loads the initial program with one programmable program load control processor. This method has the effect of reducing the number of control processors and reducing the time required to load the initial program for the entire system.
