Abstract

PURPOSE: To lighten a load upon a control computer which sends out control information at the time of a system rise by dividing the control information into information which does not depend upon the kind of an I/O module and that which depends upon it and then by setting the latter in the I/O module.
CONSTITUTION: From processor 30 in a transmission control module of a terminal controller, an interface bus is led which consists of data bus 321, buffer change-over line 323 indicating rise time and slot selection line 351 extending through a slot decoder. For I/O module 401 (one of several modules), code setter 413 setting information depending upon the kind of the corresponding module, buffers 411 and 421, gates 410 and 420, and signal converter 425 are used. For the collection and distribution of data, information which depends upon the kind of the module is processed through buffer 411 under the control of the above-mentioned gates, and the other information is through buffer 421 and by way of data bus 321.
