PACKET SWITCHING NETWORK SYSTEM

摘要

PROBLEM TO BE SOLVED: To attain unitary power source management of a terminal to which an automatic power source device is added. SOLUTION: When a power source control instruction to automatic power source devices 33-1-33-m added to desired terminals 34-1-34-m is transmitted from a terminal controller 4 through a packet switchboard 11 to protocol converting devices 17-1-17-n, the state control of MODEM 32-1-32-m faced to MODEM 31-1-31-m of the prescribed terminals 34-1-34-m corresponding to the instruction is operated by MODEM control means 18-1-18-n provided at the protocol converting devices 17-1-17-n, and the pertinent automatic power source devices 33-1-33-m are operated corresponding to this.
