Abstract:
A remote network device operatively coupled to a microprocessor, a plurality of hardware resources connected to the microprocessor, a power supply for supply power to the microprocessor and said plurality of hardware resources, and an external communication network, whereinthe remote network device is placed on a power supply path connecting between the power supply and both of said microprocessor and said plurality of hardware resources and also on a signal transmission path connecting said microprocessor and said plurality of hardware resources to the external communication network, and the device includes a switch module for performing switching of an operation voltage of said microprocessor and said plurality of hardware resources, and a stand-by module having a drive power supply independent of said power supply and normally remaining operative, said stand-by module comprising identifier means for identifying at least one of an ID information and a password information being added to a signal as received from said external communication network, and control means operatively responsive to an identification result of said identifier means for controlling said switch module to thereby control the switching of said operation voltage, wherein after turning on the operation voltage of said microprocessor and said plurality of hardware resources in response to a signal as received from the external communication network, ID information and password information are generated for addition to a transmission signal, which are different from one or both of the ID information and password information added to said signal received.
