Abstract: A method for registering a multi-terminal identification of a facsimile system and selectively transmitting the multi-terminal identification during a transmission mode. At a terminal identification register mode, a user's terminal number and a terminal identification are registered in a multi-terminal identification register table. At an automatic dialing data register mode, automatic dialing data and the terminal number are registered in an automatic dialing data register table. The terminal identification of the multi-terminal identification register table is selectively transmitted according to the received terminal number.

Abstract: A technique for controlling a ring volume and selectively receiving messages by facsimile, includes: establishing a personal reception mode; determining if the personal reception mode has been established when a ringing signal comes into a receiving-side facsimile machine; and performing the personal reception mode operations provided it has been established.

Abstract: According to a method for recording and transmitting absence information in a facsimile system, an absence information recording mode is established in response to input of a first predetermined key and the absence information is recorded while the absence information recording mode is established. The absence information includes: a destination, telephone numbers at the destination, an outgoing time and an expected return time. An absence information transmission mode is established in response to input of a second predetermined key and the absence information is transmitted upon receipt of a call signal while the absence information transmission mode is established. The absence information is re-transmitted until reception error information received in response to the transmission of the absence information indicates that a reception error has not occurred.
