Abstract
The structure described is a switching-processing node for high speed data transmission systems. Information is transmitted in time slot channels, one of which is control information. Data to be passed through a node is stripped of control characters, passed to a transmitting unit and there re-encoded with such additional data bits as needed. Data for the node is switched from an input decoder to a processor input and data for transmission is switched to a transmission unit for encoding. A switching information control frame can be passed over the system to set the switching circuits at a node to operate at the appropriate time slots of the data frames.
