Abstract

PURPOSE:To make service possible without the influence of other operation desks, by setting the operation desk, which is connected first, to the service permission state and by setting automatically other connected operation desks to the monitor state in case that one line is acquired by plural operation desks. CONSTITUTION:The incoming call from the main wire is applied to trunks 1a and 1b, and outputs of turnks 1a and 1b are supplied to operation desks 4a and 4b through link 2. When both of operation desks 4a and 4b perform the response operation, monitor information is sent from trunk 1a to operation desk 4b through control unit 3 to set operation desk 4b to the monitor state (where only receiving is possible with a high impedance), and trunk 1a is connected to operation desk 4a to set desk 4a to the service state. In case that the main wire is acquired by plural operation desks 4a and 4b, operation desk 4a which is connected first is set to the service state, and the other operation desk 4b is set to the monitor state automatically, thus making service dependent upon operation desk 4a possible without the influence of the other operation desk 4b.
