Abstract

PURPOSE:To inhibit connection with an undesired calling subscriber by an automatic telephone switchboard, by inhibiting connections between a calling and a called subscriber when detecting the called subscriber being released within a certain time. CONSTITUTION:When a calling subscriber SA calls a called subscriber SB equipped to an automatic switchboard B, a central processor CCB transfers the subscriber number of the calling subscriber SA and also acquires a free talkie trunk TKT to reserve routes 6 and 7 in a network NWB. When the called subscriber SB rejects the call after listening to the subscriber number of the calling subscriber SA, a handset is placed within a certain time, and then the central processor CCB releases the route 6 to reset the reserve of the route 7.
