Abstract

PURPOSE:In case connection is carried out to inter-office trunk through ''O'' dialing like private branch-exchange, the dialing during connection and during a fixed time after connection completion is regarded as an early-time dialing and its connection is interrupted. As a result, non-connection or mis-connection due to digit number shortage can be prevented.
