[0015]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a system block diagram of an embodiment of the present invention, and the same portions as those in FIG. 7 are designated by the same reference numerals.
In this example, the extension telephone 8 is the same as the configuration of FIG. 7 except that the extension telephone 8 has a facsimile reception button 81 (see FIG. 3) in addition to the display 82, and the description thereof is omitted.

The recipient of the facsimile transmission is the ISD.
It is assumed that the facsimile sender who has subscribed to the N network 9 is informed in advance of the called party number for receiving the facsimile and the called party subaddress which is the extension number of the recipient of the facsimile transmission. I know.

Next, the operation will be described. When a facsimile call arrives from the ISDN network 9, the ISDN interface 3 transmits the call setup message from the ISDN network 9 to the central control unit 1.

FIG. 2 shows an example of information necessary for the present invention in the call setup message received when the facsimile is received from the ISDN network 9. The central control unit 1 should receive the information that the higher layer characteristic identification of the "higher layer compatibility" information element in the call setup message as shown in FIG. 2 is "facsimile", and make an incoming call from the number digit of the "called number" information element. The facsimile machine 6 as an extension is led out, the switch 2 is controlled, and the facsimile machine 6 and the ISDN network 9 are connected via the ISDN interface 3, the switch 2 and the extension circuit 5.

Further, as shown in FIG. 3, the central control unit 1
