Mis-dialing correction system

Abstract

Abstract PURPOSE:To eliminate the need for re-dialing from the beginning, by enabling to correct the dial number when mis-dialing is made, by discriminating the special operation of a subscriber on the way of dialing. CONSTITUTION:Dial information from a subscriber SUB is received at an outgoing register trunk ORT via a channel NW, and displayed on a trunk scanning device TSCN. A central controller CC reads in the displayed information via a signal distributor SRD for storage. When a subscriber SUB desires to make dialing correction and makes a special operation such as hooking for the corrected number of digits, the central controller CC erases stored dial number for the digit's share, and the correction reception tone is transmitted by operating a relay of an outgoing register trunk ORT from a relay driver RC via the SRD. The subscriber SUB listens to the correction reception tone and makes further dialing.
