  • PABX System providing multiple paths held between calling line circuits and a plurality of output circuits
    Patent number: 4132868
    Abstract: A unique private automatic branch exchange system wherein a plurality of paths from the calling line circuits are established through the switching matrix to more than one output circuit. The paths are held simultaneously. The ability for multiple simultaneous connections eliminates the necessity for many circuits such as toll restrictors, access circuits, and such other accessory circuits. This approach not only saves hardware but also allows more features to be incorporated into the system with more efficient use of the circuits.
