    • PURPOSE:To store communication setting data from a private branch of exchange quickly to a storage device of the communication setting data of terminal communication at any time. CONSTITUTION:Terminal communication equipments U1,U2,... are connected to a private branch of exchange 1 via communication lines L1, L2,... respectively, the private branch of exchange 1 has a device 2 storing the communication setting data D1, D2,... and a device 3 using the communication setting data D1 to make communication processing to any terminal communication equipment U1, and the terminal communication equipment U1 has a device 5 storing the communication setting data D1 and a device 6 making the communication processing with the private branch of exchange 1 by using the communication setting data D1. In the private branch communication exchange system having the devices as above, the private branch of exchange 1 has a means receiving request information R1 from the terminal communication equipment U1 to output the communication setting data D1 to the communication line L1, a means by which the terminal communication equipment U1 provides request information R1 to the communication line L1 and a means storing the communication setting data D1 from the private branch communication exchange 1.

    • PURPOSE:To attain the selection or restriction or the like for an incoming call in details by registering plural incoming call numbers allocated to a terminal equipment and making incoming call valid/invalid command individually to each of incoming call numbers. CONSTITUTION:A called terminal equipment 3 having plural incoming call numbers 6 registers incoming call valid/invalid information 7 of each incoming call number 6 by an incoming call control means 5 via a communication control means 4. Then the incoming call number 6 from caller terminal equipments 11-1n and the information 7 corresponding to the incoming call number 6 are compared and when any of the incoming call numbers to be registered is coincident with the received number, any of the terminal equipments 11-1n is connected to the terminal equipment 3 via the switch means 2. Through the constitution above, call reception objects are easily limited at any time wherever and the call reception restriction to a telephone set able to receive an incoming call is attained in details in any location and in any state.

    • PURPOSE:To prevent the mishearing of numbers and to make the quick connection of the incoming calls possible by retrieving and displaying the past incoming history against the incoming calls of the same originating subscriber number given from an ISDN and therefore making the operator of an attendant board possible to connect the incoming calls while looking at the display based on the displayed incoming history. CONSTITUTION:When a subscriber of an ISDN 5 transmits a call and this call is received by a trunk circuit TRK 4, a central controller CC 1 retrieves a connection history memory MEM 2 based on the calling subscriber number information on the incoming call and displays the retrieved history data on a display device DPY 72 of an attendant board ATT 7. The operator of the ATT 7 transmits the called extension number if detected out of the display to the CC 1 via a selection input part KB 73. The CC 1 sets a message channel between an extension telephone STA 6 and the ISDN 5 via the TRK 4, a switch SW 3 and a subscriber circuit LC 8. Thus, the operator of the ATT 7 can selects the incoming calls while looking at the DPY 72 so as to prevent the mishearing the calling subscriber numbers and to quickly secure the connection of the incoming calls.

    • PURPOSE:To surely call a specific communication opposite party even when two persons or over use the same terminal equipment in common. CONSTITUTION:When a caller dials a personal number of a called party from a terminal equipment 15, a central processing unit 12 receiving the dial number retrieves a terminal number/personal number registration list stored in a storage device 13 based on the personal number and makes the connection disable when the relevant personal number is not registered or retrieves the terminal number/personal number registration list when the personal number is registered. The central processing unit 12 discriminates the presence of the connection location registration of the relevant personal number utilizing terminal equipment, makes the connection disable in the case of absence and extracts the utility terminal equipment connection location in the case of presence thereby checking its idle state. When occupied, the central processing unit makes the connection disable, and when idle, the central processing unit makes a call to the terminal equipment. In this calling, identification data of a call signal are provided in management data by the personal number of the called party and even when two persons or over use the same terminal equipment in common, an incoming call to a relevant called party is identified.
