Abstract
A communicating system has a control unit to perform a switching control of lines, a communicating apparatus which is connected to the control unit and operates in accordance with the control by the control unit and another terminal such as a facsimile apparatus connected to the communicating apparatus, wherein the communicating apparatus has connecting apparatus to connect this terminal with the control unit independently of the control by the control unit. The communicating apparatus consists of a button telephone set connected to the control unit by a communicating line and a control line. With this system, the switching operation can be performed without needing a complicated control and the connecting lines such as speech lines and control lines can be efficiently used. The user can arbitrarily switch the line of the communicating apparatus to which the facsimile apparatus is connected.
