ABSTRACT:
A control system for a communication apparatus has capability of coping with bus extension. The control system includes a control section and a plurality of controlled sections connected to the control section via a bus. Each controlled section accommodates at least one object to be controlled. The control section has a first interface for extension bus generation which includes a latch section and a bus transmission section. The controlled section has a second interface section for extension bus generation which includes a reception section, a judgment section, and a permission signal send-back section. The bus is formed by a bus which complies with a standard regarding mutual connection between apparatuses in a data communication system so as to send and receive pieces of information, each including a predetermined number of bits, and control signals. This makes it possible to suppress the hardware cost of channel sections and to efficiently perform highly functional monitoring and controlling.
