Simulating a crossbar switch in programming permits a number of terminals to be connected together so that the output from any application program is seen at all terminals and input may be made from any sequence of terminals, appearing to the application program as if from a single terminal. The figure shows the Software Terminal Switch For Teleconferencing (STSFT) crossbar matrix switch: Each terminal Tx is associated with a STSFT Logical Terminal Session Sy. The X indicates the logical connection between the terminals and the Logical Terminal Session. This connection is created, maintained and terminated by the STSFT. How STSFT works 1. STSFT is a subsystem which is imbedded in a larger system. The system (or front end) in which STSFT resides is responsible for managing all functions not included in the STSFT.
