Abstract

In an arrangement for the connection of two or more terminals (1, 1') to one subscriber line (3) the terminals (1, 1') are connected to a chain so that the connection from the subscriber line (3) to a terminal (1) is further branched (13) to the next terminal (1'), and the arrangement according to the invention is characterized in that it comprises means (18, 20) to detect whether the terminal (1) and the next terminal (1') are in the operating state or in the idle state; a controllable switch (12, 14) for each terminal (1, 1') connected to the subscriber line (3) in order to connect the corresponding terminal (1, 1') to the subscriber line (3) and disconnect it from the line; and means (18, 20) to independently control the switch (12, 14) corresponding to each terminal (1, 1') depending on which states are detected for the terminals (1, 1'). Thus it is possible, when required, to cut off the current from the subscriber line (3) in order to disconnect the connection. In order to detect the operating state of the next terminal (1') it is preferable to provide the connection (13) to it with a current meter or detector (20). With the invention one is always able to use a second terminal (1') when desired, e.g. a telephone, which is connected behind a first terminal (1), e.g. a modem. The second terminal (1') will not require any special design and it must not necessarily be able to be connected in a chain.
