Abstract

In some large data processing installations the terminals need to change their system connection points, so that individual users may access any of several ports or groups of ports into a plurality of computer systems. The traditional approach is to provide a plurality of cables and dedicate ports to specific terminals.

Remote Controlled Terminal Switch and Concentrator

In some large data processing installations the terminals need to change their system connection points, so that individual users may access any of several ports or groups of ports into a plurality of computer systems. The traditional approach is to provide a plurality of cables and dedicate ports to specific terminals.

According to this method, controlled access is provided from any of a plurality of computer terminals to any of a plurality of input/output ports on one or more computer systems. An audio response computer system serves as a combination switch and concentrator under user control via Touch-Tone* telephones. The user keys in his own personal ID number, and those of the terminal and system, for authorization and selection of the terminal to system port by the audio response computer.

The system for interconnecting a plurality of users at terminals 1 with computer systems 6 includes CPU 7, such as an IBM System/7, controlling coaxial crossbar switch 5 and communicating with the users at Touch-Tone telephones 2 in an audio response output/Touch-Tone digital input mode through Data Phones* 4.

In operation, the user calls CPU 7 from one of Touch-Tone phones 2. CPU 7 responds by requesting that the user enter his secret number identifier at the Touch-Tone keyboard. The user responds, whereupon CPU 7 requests similar input of the terminal 1 identifier and system 6 identifier with respect to which access is...
