Abstract
PURPOSE:To perform bridge cut off without preparing a new unit, by using the digital conference trunk for bridge cut off for confirmation of the subscriber's number from the toll board. CONSTITUTION:When subscriber 200 originates to toll board 204, suspended re-call connection trunk 202 and digital conference trunk 207 are acquired simultaneously through time division service switch 201 and are connected to form the service path between subscriber 200 and operator 205. For dialing from toll board 204 for confirmation of the calling subscriber's number, offering incoming connection trunk 203 retrieves trunk 207 to connect channel highway 212 and digital conference trunk 207. As a result, operator 205 can listen to sound source 206.
