Abstract

PURPOSE: To increase the degree of freedom by storing a computer side with all of programs a communication controller (CCU) side needs, by transferring them to RAM on the CCU side at need, and then by executing the programs by CCU having received them.
CONSTITUTION: Computer 2 is equipped with H-CPU4 including main memory 3, auxiliary memory 5, and channel unit 6 connecting H-CPU4 to CCU1, and memory 5 is stored with all of programs that CCU1 needs. Then, CCU1 is provided with μ-CPU7, RAM8, DAM circuit 9, interface circuit 10 performing series-parallel conversion, etc., and power feed detecting circuit 11 generating a signal by detecting power feed. Additionally, terminal equipments T1, T2 and T3 are coupled with CCU1 via a communication circuit.
