I ON Denshi Tokyo N24 (19
85) As shown in Figure 2 shown on pages 21 to 23, one type of communication terminal device such as a facsimile machine + 81 is fixedly connected to one telephone line and makes a call. The party knows in advance the correspondence between the other party's phone number and the type of communication terminal connected to that phone number.
When it was desired to communicate with a particular communication terminal device, the communication was carried out by making a call to the corresponding telephone number.
