ABSTRACT:
A telecommunications system which is capable of implementation in many configurations. The simplest and smallest configuration is that of a single processor-controlled module or unit using time division switching. Within a module, a processor and its attendant memory provide program memory and control the functioning of an automatic scanner driver, the automatic scanner driver interfacing between the processor and the system terminal circuits. In addition the automatic scanner driver has capability of storing temporary information during call processing through a time division switching network. For configuring larger systems, plural modular units are combined, the units being combined with control elements common to the system such as a control processor, including memory and a processor to module interface and module to module interface. The common elements act to control the feeding of information between modules. In this way, one family of systems may provide systems of any desired size from small (50 lines) to many thousand lines.
