Abstract

PURPOSE:To reduce the probability of double catching, by performing the assignment to incoming call of ground relay line coupled with the ground relay exchanger connected to each remote station at a remote station. CONSTITUTION:The memory unit M1 of the earth station ES1 provides the information related to the state of usage of the satellite lines 21-2i and the information related to the state of usage of the ground relay line 31 of the station, and the memory units M2-Mi of the remote stations ES2-ESi provide respectively the information related to the state of usage of the ground relay lines 32-3i of the station. The incoming earth station ESi receiving the line assigning signal references the memory information of the state of usage of the ground relay line 3i of the memory unit Mi and selects the vacant ground relay line 3i2. Accordingly, the outgoing ground station ES2 and the incoming earth station ESi receiving the assignment of line control the line connection unit of the ground relay line 3i2 and set the satellite lines 22, 2i between the both earth stations ES2 and ESi.
