ABSTRACT:
A telecommunications system for both PABX and key systems use.
The system is assembled in modules capable of physical and electrical interconnection and expansion. The system has a control apparatus housed in one modular sectional unit. The stations of the system are grouped with the control for each group being housed within a sectional unit. The units are adapted for physical mounting to one another and each unit is electrically connected into the system by two flat conductor cables jumpered to the adjacent unit. This modularity is made possible by each unit having internal bus structure for the bidirectional flow of information in the module, the intermodular connection acting as the bus between groups and the central control. Further, each group has a data memory for storing information directed into or out of modular unit on a random basis for reading out that information when the destination module is ready to receive that information.
