Abstract

PURPOSE:To grasp a telephone line by displaying the state of all telephone sets with INTERCOM being components of a telephone system onto each set. CONSTITUTION:Let a terminal equipment receiving a set number at first be No.1, then the No.1 terminal equipment outputs the set number No.1 and a data such as its own operating state to other terminal equipments No.2-8 via an extension 1 from a state data output section 9. Other terminal equipments No.2-8 receiving the state data from its state data input section 1 use a state data processing section 3 to discriminate it that the terminal equipment sending the state data is No.1 and the operating state of the terminal equipment and the result is outputted to a storage section 5. The storage section 5 stores the state of the terminal equipment No.1 and outputs it to a set state output section 6 together with the state of the terminal equipments No.6-8 stored so far. Then an LED display section 7 is controlled in response to the content to display the state of a terminal equipment in the telephone system.
