Intelligent teleprinter group terminal system - has cyclic scanner allowing each station to operate at individual maximum capacity

摘要

The system includes several station connector modules (LAM) which each control the interface with a group of stations (T1-Tn) having equal data rates. Each station is provided with a microprocessor (MP1-MPn) and data acceptor input (De) for the teleprinter sender (S1) for storing message blocks in the microprocessor memory. Data output (Da) is applied to a serial buffer register (SK1 to SKn) and a clock-pulse input (To) receives clock pulses from a counter (Cnt). The counter applies enabling (logic'1') signals (a1-an) sequentially to an enable input (INT) of the microprocessors during which each sampled microprocessor passes the accumulated message contents to the control network (VA) an outgoing AND gate (G1). An incoming 'AND' gate (G2) passes message data from remote teleprinters to the receiving bus (DB) of the microprocessors (MP1-MPn).
