Transmission of data in ISDN network

摘要

Data flow, from an Electronic Data Processing system, is fed directly for analysis and stored, according to control and user strings, and the electronic units are part of the program for running package and programme control. A second control unit activates a switch providing a connection between the buffer memory used and a matching and reduction control. This last unit performs a reduction of the data, again separating user and control information. For EDP installations there is a virtually direct connection.
