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.

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 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.

A communication apparatus includes a communication unit for performing a communication, a speech communication unit for performing a speech communication, a detection unit for detecting the telephone number of the calling side before connection of a call, a registration unit for registering the telephone number of the calling side, and a switching unit for switching a communication mode between the communication unit and the speech communication unit on the basis of the telephone number of the calling side detected by the detection unit, and the telephone number registered in the registration unit.
摘要:
In a communication apparatus (e.g., a facsimile apparatus) having ITU-T V. 8 and V. 34 recommendations, when it is determined that a partner has the V. 8 and V. 34 functions, the apparatus omits detailed determination processing of reception of an ANSam signal in V. 8 communication, and shifts control to transmission of a CM signal in the V. 8 communication, thereby shortening the time required for the V. 8 communication.

摘要:
The invention provides a facsimile apparatus which can perform the re-transmitting operation adapted to receive reception data in a good state on the reception side upon error re-transmission when a both-side document sheet is transmitted. At the time of a facsimile communication, the presence or absence of a both-side reception function is notified from a receiver to a transmitter and the both-side document sheet is designated by a DCS signal from the transmitter to the receiver. When the both-side document sheet is designated by the DCS signal, the front side and the reverse side are sequentially transmitted. When shifting to a one-side document sheet in the middle of the page, the one-side document sheet is designated by the DCS signal by returning to phase B. When the one-side document sheet is designated by the DCS signal and transmitted and the sheet is shifted to the both-side document sheet in the middle of the page, the both-side document sheet is designated by the DCS signal by returning to phase B and, thereafter, the front side and the reverse side are sequentially transmitted. As for the error re-transmission when an error occurs during the communication, the re-transmission from the front side is always performed upon transmission of the both-side document sheet.
摘要:
There is disclosed a communication apparatus designed to assure the execution of ring type multi-address data transmission. In order to ensure that a user see a received image, transfer to a next station is not carried out until the received image is printed out. With the passage of specified time after the reception of the image, transfer is executed to the next station.

摘要:
The present invention relates to a facsimile apparatus for providing a single/dual side mixture mode capable of transmitting and receiving original images including single/dual side mixture efficiently. Under control of a CPU 22, information indicating presence/absence of back side image information corresponding to transmission/reception image information is informed together with page number and image front/back information, by a post message signal transmitted from a transmitter to a receiver. If the image information read from a back side of an original is substantially entire-white, the transmitter omits transmission of back side image information having the entire-white. In this case, by informing information indicating absence of back side image information corresponding to front side image information from the transmitter to the receiver by the post message signal, single/dual side mixture image informations can be transmitted and received.
