Abstract

PURPOSE: To make it possible to transfer efficiently data between a data channel unit and an input-output unit through small hardware.
CONSTITUTION: Once a service-in signal is inputted, FF17 is set and internal processing circuit 24 starts operating. When FF17 is set newly to complete the operation, internal processing circuit 24 outputs a pulse of logic [1], so that FF18 will be set. The set output of FF18 is sent out as a service-out signal via cable driver 2-1. With the service-in signal reset, AND gate 7 outputs logic [1], which is transmitted to AND circuit 11 via OR circuit 15. Then, AND gate 11 generates a pulse output, by which FFs 17, 18 and 19 are all reset. In case of a data-in signal, nearly the same operation is carried out.
