Abstract

PURPOSE:To avoid unnecessary dialing of a subscriber, by connecting an outgoing subscriber to an outgoing line, after a vacent waiting tone is transmitted to the said subscriber and the outgoing line is vacant, when the outgoing subscriber encounters with congestion of an outgoing channel. CONSTITUTION:With subscribers SUB1-SUB3 connected via all trunks OGT1- OGTn of a route (m), when subscribers SUB4, SUB5 make outgoing call to the route (m), the subscribers are connected with a vacancy waiting signal trunk TNT with a known method. The TNT transmits a signal instructing outgoing route choke and vacancy waiting to the SUB4, SUB5. A controller CC connects this vacant trunk and the SUB4 or SUB5 via a network NW, when one of the OGT1-OGTn is vacant because of the end of call.
