摘要:
A CI signal of a V.8 protocol is transmitted in response to the reception of a DIS signal indicating the provision of a V.8 facility, and the V.8 protocol is executed in response to the reception of an ANSam signal of V.8, and when the DIS signal indicating the provision of the V.8 facility is received without receiving the ANSam signal, the CI signal is retransmitted. When a transmitting station or a receiving station does not have a V.34 facility after the V.8 protocol, the DIS signal indicating the non-provision of the V.8 facility is transmitted. Thus, when the V.8 protocol facility is provided with a facsimile apparatus, communication with a conventional apparatus having only a T.30 protocol is attained.

A facsimile communication system and a communication apparatus reduce a loss time due to the synchronization of transmission/reception and shorten a communication time. They also shorten a communication time in a full duplex communication mode and allow proper switching of the full duplex communication at the transmission/reception replacement. DIS-CFR signals, EOP-DCN signals, NSS-TSI signals and TSI-DCS signals of a facsimile communication protocol are connected by synchronization signals so that the synchronization signals are sent even after the sending of the protocol signal. Thus, the sending of the synchronization signal for one second when the next protocol signal is sent is not necessary and a time required for the protocol signal is shortened. An ANSam signal to disable a function of an echo suppressor is sent when a call is detected and a calling station thereafter sends a protocol signal and an image signal in a manner not to cause signal interruption of 50 ms or longer, and at transmission/reception replacement at the end of the image signal from the calling station, a called station sends an ANSam signal and sends a protocol signal.

In a data communication apparatus, the baud rate and the bit rate of a modem thereof are set independently of each other according to the condition of data communication. Thus, optimum data communication suited to the line condition can be performed.
摘要:
A communication apparatus receives the identification information of a partner station, and performs a communication operation in accordance with the received identification information. A first detecting unit detects a calling signal. An identification information receiving unit detects the identification information of a calling party upon detection of the calling signal, and a second detecting unit detects whether or not the terminal of the calling party is a data communication terminal. A registration unit registers the identification information of the partner station in a memory, so that whether the partner station is a speech or data communication terminal can be discriminated later. A control unit checks if the identification information receiving unit receives the identification information of the calling party. When the identification information of the calling party is received, the control unit checks if the-received identification information is registered in the memory, and selectively executes a speech communication process and a data communication process in accordance with the checking result and the detection result of the second detecting unit.
摘要:
A communication system in which when an incoming call has arrived, a communication line having the capability of a high sampling rate is automatically selected without assistance of an exchange operator by transmitting an ultra high speed modem indication signal indicating the capability of data communication at an ultra high speed modem rate among the capabilities of a called terminal, and receiving an ultra high speed modem capability signal indicating the capability of an ultra high speed modem of a calling terminal.

A communication apparatus is provided which makes it possible to print out all data larger than a display screen in one operation. In addition, the communication apparatus reduces time required for print processing and eases a user's stress due to print waiting by diverting the data for display as the data for recording. In addition, the communication apparatus analyzes received data, generates data for display indicating a screen to be displayed on a display unit and generates data for printing from data for display corresponding to a plurality of screens according to an instruction of printing.

In a portable facsimile apparatus according to this invention, each recording paper (or each document to be transmitted) may be set in place by manual operation. In a case where the portable facsimile apparatus needs additional recording paper (or an additional document) to be set by an operator during image reception or image transmission, the portable facsimile apparatus so informs the operator, while the apparatus delays shifting following image reception or image transmission. As a result, the operator can set additional recording paper (or an additional document) into the portable facsimile apparatus, during image reception, without terminating the image reception.
摘要:
A facsimile apparatus comprises a housing constituting the outer surface of the facsimile apparatus, an original reading section for conveying an original between a first opening portion formed in a front portion of the upper surface of the housing and a front surface opening portion formed in the front surface of the housing, and a recording section for inserting a recording sheet through a second opening portion formed in the upper surface of the housing at a position closer to the rear side than the first opening portion and for discharging the recording sheet through the first opening portion. A cut sheet can be inserted/discharged through each opening portion. Since the first opening portion is commonly used for both an original and a recording sheet, the depth of the housing can be reduced. In addition, the housing can be designed to be flat and compact so as to be easily carried. The apparatus further includes a storage portion for a battery detachably set through a side surface on the rear side of the housing. A cut sheet can be inserted/discharged through each opening portion. Since the first opening portion is commonly used for both an original and a recording sheet, the depth of the housing can be reduced. In addition, the housing can be designed to be flat and compact so as to be easily carried. Furthermore, the apparatus can be used in a place where no commercial power supply is available, by receiving power from a battery.
摘要:
A communication apparatus for an exchange network having a service of notifying the telephone number of a caller during a call-receiving operation can recognize respective callers of past call-receiving operations. During a call-receiving operation, a communication partner's telephone number detection unit detects the telephone number (identification information) of the caller, and stores the detected telephone number in a nonvolatile RAM (random access memory). The RAM can store a plurality of sets of identification information, which are recorded and output in the form of a list by a recording unit.
