IPC: H04Q3/545
Filed: 1990-11-29
Abstract: PURPOSE:To reduce cost by selecting a small representative group in a large representative group with the selection of the representation of a terminal equipment in the small representative group and setting the same terminal equipment to be common in plural representative groups. CONSTITUTION:When a slave extension 201 is used for an incoming call for the slave extension 201 in the small representative group 1 from a central office 14, a central processing unit 12 extracts the small representative group 1 from a small representatibe group list stored in a storage device 13. Since the type of trunk line representative selection is a switch back system, the small representative group 1 makes a round in the representative group until the idle extension of the small representative group 1 is detected. If all the slave extensions are busy, a large representative group list is referred to based on a master extension 200 in the small representative group 1, and the master extension 300 of a next small representative group 2 is extracted. Thus, the extension of the unnecessary terminal equipment is not required and cost can be reduced.
