Abstract

PURPOSE:To offer economical incoming tansfer service by eliminating the need for a complex and expensive incoming transfer unit by providing two terminals on a main frame to an incoming transfer service subscriber and then by setting up as a two-circuit group between those terminals with master and subordinate circuits. CONSTITUTION:Subscriber SUB to which incoming transfer service is offered is provided with two equipment position terminals on main frame LINK and the parental relation is established as a two-circuit group between both those terminals; one parent circuit is connected to service subscriber SUB, and the other child circuit to the parent circuit through incoming transfer trunk TFT. While subscriber SUB sends no transfer request, the child circuit is made busy and a general call from the parent circuit is started. When a transfer request is sent, on the other hand, the parent circuit is made busy only at the time of incoming and the busy state of the child circuit is released. A call to subscriber SUB is considered to be child-circuit incoming, which is resent from the parent circuit through trunk TFT, thereby making a connection to a transfer destination.
