PURPOSE:To shorten the data(DT) packet transfer time by transferring an incoming transfer list from an original called station to a caller station and applying the incoming call transfer processing according to the leadership of the caller station so as to omit useless relay processing by the original called station in the data transfer after the end of call setting. CONSTITUTION:When a caller station (A) 1 transfers a usual caller request(CR) packet to an original called station (B) 2, the original called station (B) 2 sets a called party transfer destination for a subscriber (b) 12 set in a main memory(MM) and incoming call transfer request display to a restoration request (CQ) packet when the arrival of the call to the subscriber (b) 12 is disabled and transfers the result to the caller station (A) 1. The caller station (A) 1 fetches the incoming call transfer destination list for the subscriber (b) 12 set in a restoration request (CQ) packet and applies initial setting to a subscriber selection pointer. Thus, no original called station (B) 2 exists among subscribers (a) 11-(d) 14 connected finally and the data transfer time is reduced. |
