PURPOSE:To ensure an international subscriber dialing connection for a calling subscriber just by dialing the called subscriber number after the international subscriber dialing special number, by extracting the called subscriber number out of an originating register and therefore eliminating the transmission of the 2nd dial tone. CONSTITUTION:When a calling subscriber SUB dials a called subscriber number after an international subscriber dialing special number, an originating register OR receives the called subscriber number and actuates a calling subscriber number detector IDE via a connector. The IDE receives both the OR number and the called subscriber number and then stores temporarily the called subscriber number in correspondence to the OR number. Then the IDE transmits the storing position information, the international subscriber dialing special number, etc. to a common controller MKR via an ORMC after sending the start information of the MKR to the OR. The MKR identifies an international subscriber dialing call and then actuates a special number outgoing trunk OGT-SP. When a primary channel is set up, the OGT-SP actuates an outgoing sender OS via an OSL and transfers a trunk number to the IDE. The IDE extracts the called subscriber number out of a memory area on the basis of the trunk number. |
