Abstract

PURPOSE:To make the trunk having a transfer control function needless by performing an order service by the connection switching of service pathes in the channel and a normal mutual service trunk. CONSTITUTION:When telephone sets 1 and 2 are in service through trunk 12 and service path 13, a service path is switched from path 13 to path 14 by the transfer request of telephone set 1, and selection number information to transfer destination telephone set 3 is received from number receiving trunk 9, and telephone set 3 is called on a basis of this information to perform the connection switching to mutual service trunk 15, thereby performing the order service between telephone sets 1 and 3. Further, the service path is switched to path 18 by the transfer request from telephone set 1, thereby performing the service between telephone sets 2 and 3.
