Abstract: A facsimile machine where a plurality of re-call intervals and frequencies are set on a system basis or on a destination terminal basis depending on communication modes and communication quantities to perform re-calling operation as necessary according to the conditions set on the system basis or on the destination terminal basis.

Abstract: A communication terminal apparatus and its control method which allow the parallel execution of a plurality of communications with use of a plurality of data channels. The terminal apparatus comprises an image main controller and a voice main controller which can be operated independently of each other, two network controllers operated as associated with the operations of these image and voice main controllers respectively, two image transmission control circuits which are operated independently of each other, and an image file capable of storing image and voice data, thereby realizing the simultaneous execution of image and image communications and the simultaneous execution of voice and voice communications on a duplex communication basis.

Abstract: A communication terminal device connected to a communication network via a plurality of information channels used for transfer of information such as line switching information or packet switching information and a signal channel used for control of calling an objective communication terminal. In the device, two CODECs are provided in two corresponding information channels among information channels and analog sources such as a handset and a communication function control unit operative in a G3 facsimile mode for encoding and converting switching information, supplied from the analog sources to the information channels, to a digital signal, and decoding and converting switching information received from the information channels, to analog signals. Analog switches are provided between the analog sources and the CODECs to switch among the analog switches and these CODECs to send and receive signals to and from the analog sources and the CODECs.

Abstract: A terminal switching control apparatus includes a controller. The controller responds to one of a record stop (RS) signal, a communication signal from a telephone, and a facsimile communication end (FCE) signal from a facsimile to monitor a call detect CED signal from a call detector. The controller determines whether the mode set by a mode setting section is a first mode or a second mode, in response to the CED signal from the call detector. In the first mode, the controller responds to a CNG detect signal from a CNG detector within a first time period and outputs a switch control (SC) signal to a switch so as to couple a communication line to the facsimile, and then responds to the communication signal upon elapse of the first time period and outputs the SC signal to the switch so as to couple the communication line to the telephone.
