发明名称 SATELLITE COMMUNICATION SYSTEM
摘要 PURPOSE:To connect an outgoing terminal equipment and an incoming terminal equipment via one satellite line by giving/receiving information relating to the use of the satellite line between exchanges and setting the satellite line again every time a line block by the satellite line is selected. CONSTITUTION:An incoming call terminal equipment 43 is a terminal equipment accommodated in a satellite line and connecting to a satellite line 102. An exchange 33 makes a request of a change in a setting block of a satellite line from a terminal station 56 closest to the terminal equipment 43 into a terminal station 51 closest to an outgoing terminal equipment 41 to a line controller 20. The controller 20 executes the processing to change the line 102 into the satellite line 103 and informs it to the exchange 33 when it is finished. The exchange 33 sends a setup signal to the terminal equipment 43 via a subscriber signal line 112. The terminal equipment 43 sends a reply signal thereto to the exchange 33 and the reply signal is informed to the terminal equipment 41 via a relay signal line 130, exchanges 32, 31 and a subscriber signal line 111. Thus, the terminal equipments 41, 43 start transmission and reception of terminal information via the satellite line 103 interconnecting directly them.
