摘要:
There is disclosed a communication system, and an apparatus therefor, for use in combination with an integrated service digital network. The proposed system, and the apparatus, can achieve a change of service from an equipment to another, for example from a telephone unit to a facsimile unit, both connected to a same telephone line, without disconnecting a call made through the telephone line. For this purpose, the proposed system or apparatus has a discriminating unit for identifying a request for communication released from another unit connected to the same telephone, and a communication control unit for automatically communicating with a destination unit with which said another unit has been communicating through said telephone line.

Zum Zurückschalten einer Faxübermittlung gemäß T.38 auf eine Sprachübermittlung über ein IP-Netz wird vorgeschlagen, die im Media Gateway Controller (11) auf der B-Seite gespeicherten Übermittlungsdaten über ein Signalisierungsnetz (12) an den Media Gateway Controller (10) auf der A-Seite zu übertragen und dadurch ein gemeinsames Rückschalten der Codecs in dem Media Gateway (3) auf der A-Seite und dem Media Gateway (4) auf der B-Seite zu bewerkstelligen.
摘要:
A facsimile machine (20) has a calling-side/called-side judging unit (14) for judging whether the facsimile machine is a calling side or a called side, a handset (7) for sending and receiving sound through a communications network, a speaker (5) capable of outputting a ring tone for calling up the operator while converting electric signals supplied from the communications network into sound and outputting the sound, and a control unit (1) for controlling the speaker and the handset so as to selectively cause signals supplied from the communications network to be converted into sound and outputted by the speaker after the facsimile transmission or cause a ring tone to be outputted by the speaker after the facsimile transmission, depending on judgment by the calling-side/called-side judging unit. With this arrangement, the facsimile machine is capable of smoothly switching to telephone communication after facsimile transmission without disconnecting from the communications network.
摘要:
An object of the present invention is to provide a facsimile machine having a telephone conversation function, which can securely shift the facsimile communication mode to the telephone conversation mode after facsimile communication even if an error occurs during facsimile communication, without using a telephone conversation reservation function. After facsimile communication is started, when facsimile communication is stopped through the transmission of predetermined signals between the calling party side facsimile machine and the receiving party side facsimile machine in case image data to be transmitted is completely transmitted or when a communication error occurs because of paper jamming, the main controller (12) keeps occupying the communication line (1) occupied by the line controller (2), and the signal sound on the occupied communication line (1) is externally emitted by the speaker (11). When the calling party recognizes that the receiving party requests a call depending on the signal sound transmitted from the communication line (1) and externally emitted by the speaker (11) and lifts the handset (3), the lifting of the handset (3) is detected by the hook switch (4). The main controller (12) then controls the line controller (2) to enable conversation with the receiving party side facsimile machine via the handset (3).
摘要:
In a communication between transmitter-side and receiver-side communication control devices, when a data communication is desired after a facsimile communication without opening a telephone line, the transmitter-side communication control device transmits a data communication shift request signal to the receiver-side communication control device based on a previous command inputted to the transmitter-side communication control device. In response to this request signal, the receiver-side communication control device switches a communication mode from a facsimile communication mode to a data communication mode, and then sends back a data communication shift acknowledge signal to the transmitter-side communication control device. In response to this acknowledge signal, the transmitter-side communication control device switches a communication mode from a facsimile communication mode to a data communication mode. Accordingly, the data communication can be performed automatically after the facsimile communication without once opening the line. Such a data communication after the facsimile communication may also be realized based on a data communication shift request signal from the receiver-side communication control device.
