A multi-function apparatus having a wider variety of uses and easily employed when carrying a USB cable only without having a power source cord. The apparatus includes means for detecting a connection between the USB interface and the PC, means for detecting a connection to the power line, and control means for selecting a function depending on a detected state of the connection between the USB interface and PC and a detected state of the connection to the AC power line. All the functions in the multi-function apparatus are operable in a connected state of the AC power line to the AC power source, while even in an unconnected state of the AC power line to the AC power source, if the USB interface is connected to the PC, a possible operation is enabled using electric power of 5 V at 500 mA supplied from the PC.

Multi-function apparatus and control method thereof

There is provided a bridge which connects between a primary bus and secondary bus. The bridge reads out a descriptor from a primary memory of the primary bus, reads out a status from a secondary memory of the secondary bus, writes, into the primary memory of the primary bus, the readout status in accordance with the descriptor, and writes, into the primary memory of the primary bus, a flag indicating completion of the write of the readout status.

Bridge and data processing method therefor

In a bridge which connects between an expansion bus of a primary system and that of a secondary system, a local error such as an expansion bus error and CPU hang-up which occurs in the secondary system is recognized. The primary system is notified of the local error as a system error.

Bridge, error notification method therefor and system

In a communication system having a network capable of converting data in a first format into data in a second format to perform communication, and a data communication apparatus capable of performing communication of the data in the first format, the data communication apparatus transmits information indicating a priority level of an image such that the network can recognize the information, when transmitting the image to the network in the first format. The network converts the data in the first format transmitted by the data communication apparatus into data in the second format, and attaches priority level data, based on the information indicating the priority level of the received image, to the data converted into the second format when performing communication.

Network that converts data from a first format into a second format for communication, data communication apparatus capable of communication of data in a first format, communication system incorporating all the above, and control method for all the above

An object is to provide an image processing apparatus which can reduce power consumption during the power saving standby mode. The starting factor monitor unit and the power saving standby mode voltage control unit are driven with the USB bus power can be supplied during a shift to the power saving standby mode and the starting factor monitor unit and the power saving standby mode voltage control unit are driven by voltage from the main power supply when the USB bus power cannot be supplied during a shift to the power saving standby mode.

Image processing apparatus, power saving control method, and program and storage medium thereof

When a data communication apparatus as a sender gateway receives instruction information for instructing a communication system via ITU recommendation T.38 or a communication system via ITU recommendation T.37 from a sender facsimile apparatus as an analogue communication terminal, data communication is executed with respect to a recipient connected gateway on the basis of the communication system instructed by the instruction information.

Communication apparatus and communication method

Disclosed is a communication apparatus connected to an analog public line, which can be actualized at low costs and can save its space. This communication apparatus includes a first communication means connected to a telephone line, for performing communications, and a connecting means for connecting a second communication means connected to the telephone line via the first communication means and thus performing communications. In this communication apparatus, the first communication means has a first switch means for connecting the telephone line to the first communication means or the second communication means, a first route means for connecting the second communication means to the telephone line via the first switch means, a second route means for connecting the second communication means directly to the telephone line, a second switch means for connecting the second communication means to the first route means or the second route means, a first hook detecting means connected to the first route means, and a second hook detecting means connected between the telephone line on the second route means and the second switch means.

Communication apparatus

In a communication system having a first communication apparatus capable of a first communication via a first communication line such as a wire line and a second communication apparatus capable of a second communication via a second communication line such as a wireless line, information input from an information input unit of the first communication apparatus is transmitted over the second communication line via the second communication apparatus.

Communication system capable of speech and facsimile communication

NETWORK THAT CONVERTS DATA FROM A FIRST FORMAT INTO A SECOND FORMAT FOR COMMUNICATION, DATA COMMUNICATION APPARATUS CAPABLE OF COMMUNICATION OF DATA IN A FIRST FORMAT, COMMUNICATION SYSTEM INCORPORATING ALL THE ABOVE, AND CONTROL METHOD FOR ALL THE ABOVE

A communication apparatus includes a main unit and a communication control unit. The communication control unit informs the main unit of an incoming call. The main unit makes a judgement on whether the incoming call should be accepted. In accordance with this judgement, the main unit instructs the communication control unit to respond to the incoming call. The communication control unit responds to the incoming call in accordance with the judgement by the main unit. In accordance with the state of a memory for storing received signals or with the called party number, the main unit makes a judgement on whether the incoming call should be rejected or ignored.

A communication terminal having an interface to which its components including an analog telephone are connected and which enables communication with another terminal at the other end of a line of the integrated services digital network. A first tone is generated to set the period of time for dialing of the analog telephone, a second tone different from the first tone is generated to set the period of time for connection between the analog telephone and the terminal at the other according to the dialing during the period of time when the first tone is being generated, and a third tone different from the first and second tones is generated to set the period of time for terminating communication using the analog telephone when the connection established during the period of time when the second tone is being generated is cancelled. Each of first, second and third tones generated is output to the analog telephone.
