Abstract

The goal of the connection of the connection computer station is the possibility of creating a computer network within one or a group of buildings with the possibility of modem connection to the World Wide Web. The principle of the connection lies in the fact that the control microcomputer module is connected with the internal system bus, which is connected with the two-access memory of the peripheral processor unit. Its second access is connected with the peripheral processor unit, which is interconnected via the communication interface with the common distribution panel, which connects with the communication links of satellite computers. The connection of the connection computer centre can be used in all fields of computer technique for interconnection of the same and different computer systems where the only condition of the interconnection is existence of a serial communication channel with the standardized interface.<IMAGE>

Description

The invention relates to the connection of a computer interconnection center which enables the creation of a computer network within one or a group of buildings with the possibility of modem connections over a global computer network.

So far, minicomputer systems and personal computers have had the following options for creating heterogeneous computer networks: creating a network with a circle-to-carrier approach, a time-division ring, a collision detection bus, and a time-division bus. A common disadvantage of these solutions is the necessity of implementing communication adapters in each connected computing system and the considerable complexity of the communication protocol, which greatly increases the intelligence requirements of the communication adapters.

The above drawbacks are substantially eliminated by the wiring of the computer interconnection center of the invention, which is characterized in that the control microcomputer module is connected to an internal system bus which is connected by a first access to the dual access memory of a peripheral processing unit. Its second approach is associated with a peripheral processing unit, which is interconnected by means of communication interstices to a common distribution panel to which the satellite computer communication lines are connected.

The advantage of wiring a computer interconnection center lies in the replacement of costly communication adapters with a simple serial intermediate, parallel standard intermediate, transformation! transfer rates and implementation of various types of interfaces such as current loop intermediate, modem intermediate and parallel intermediate. A parallel intermediate allows the system printer to be connected before use by all communicating computing means. The modularity of the wiring enables easy expansion and chaining of intelligent switching centers. The transmission parameters are programmatically selectable on individual communicating lines and can have different values.

The attached drawing shows schematically the connection of a computer interconnection center.

The computer interface comprises a control microcomputer module 21 having a parallel interface 10 for connecting a common communication system device and connected to the internal system bus of the computer interface 2, to which the dual access memories of the peripheral processing units are connected by the first access 23. The second access 34 of the dual access memories is coupled to a peripheral processing unit 8, which is connected to a common distribution panel 5 by four serial communication interfaces 45. Communication lines 50 are connected to the distribution panel according to the required number of network subscribers.

In the case of a request for interconnection of two communication lines, the computer system of the computer interconnection center control module performs a logical interconnection of lines based on a defined request from the line. The connection of the communication line 50 is realized by writing data from the communication line 50 to the dual access memory 2 of the peripheral processing unit. The control module microcomputer rewrites the data in the dual port Salsa pamati prepojonia 2 according to a communication line 22 .. The peripheral processor unit transfer the £ 45 medzistyk through the distribution panel 2 ^{and the} communication line 50 to the programmable parameters of the transmission.

The computer interface can be used in computer technology to interconnect various types of computing systems, personal computers, microcomputers and minicomputers, for remote terminal functions, distributed data processing, file transfers, etc.
