Device and method for supplying power to computer peripheral equipment using the bus system of the computer
First Claim
1. Apparatus for the power supply of auxiliary implements of computers via the bus system of the computer, in which there is provided an energy store in the auxiliary implement supporting the power supply of the auxiliary implement and which by a suitable charge circuit is connected with the power supply in the bus system of the computer, comprising a first switching device between the power supply in the bus system of the computer and the charge circuit;
- a second switching device which is provided between the energy store and the power supply of the auxiliary implement with a third switching device being provided for directly connecting the power supply in the bus system of the computer with the power supply of the auxiliary implement.

- 3. A method for starting a computer being connected by an auxiliary implement and a bus system with an ISDN-system from a sleeping or resting state into an active operational state, wherein the procedure of start-up of the computer is triggered if after a call arriving on the ISDN-system has been determined to actually be meant for the computer by independent processing of a D-channel protocol of ISDN, and wherein the method comprises providing the auxiliary implement with an energy store supplying the energy for the processing of the D-channel protocol and which in the sleeping or resting state of the computer is recharged from the bus system with the very low current.
