PROBLEM TO BE SOLVED: To realize a mobile phone terminal which is flexibly extended when requiring addition of new processing parts. SOLUTION: A line interface part 2 is connected to a demultiplexing part 4 through a CPU bus 3, and multiplex data is transmitted in parallel between the line interface part and the demultiplexing part 4 through the CPU bus 3 by the control of a CPU 11. Thus, a new processing part is added without changing connection relations between respective processing parts when it added. COPYRIGHT: (C)2004,JPO&NCIPI
