Abstract

PURPOSE:To eliminate the need to provide a dedicated PB incoming register, by providing the subscriber-equipped terminal of an automatic switchboard with special terminals for switchboard origination. CONSTITUTION:As subscriber SL asks switchboard ATT for a connection via trunk line TL, SL and switchboard inward trunk IWT are connected together in route 1 via line link network LLN and trunk link network TLN. Assuming operator's trunk PST to be in an originating state, switchboard outward trunk OWT detects the originating state of PST and finds a random free terminal among special terminals for switchboard origination to connect AL and PB originating register AL PBOR via route 4. Simultaneously, interruption route 5 is set via LLN and TLN from OWT to route 4. Dial information on a connection via TL from ATT is sent out of push-button dialing (PB) signal sending means PBS as signal PB. This signal PB is received by PB reciver PBR via route 4 and 5. Once it is judged that the dial information received by PBOR is for the connection via TL, route 5 of OWT is broken and it is connected to OGT via route 3. Further, route 4 is also released and PBOR becomes free. Then, SL and the called subscriber are connected together via routes 1 and 3.
