Commercial satellite communication system for controlling multiple aperture terminals through a public communications network.

摘要

In a satellite business communciation system comprising a plurality of aperture terminals, a supervising station is coupled to the aperture terminals through a public communication network to centralize a monitoring operation of each aperture terminal. Each of the aperture terminals has a terminal directory number and a terminal identification address while the supervising station has a primary directory number. A monitoring item is transmitted from the supervising station to a selected aperture terminal along with the terminal identification address of the selected aperture terminal and the primary directory number after a transmission path is formed by the terminal directory number through the public communication network. A result of monitor in the selected aperture terminal is sent as a response signal back to the supervising station through a return path formed by the use of the primary directory number. The result of monitor may be stored in a status memory or be transmitted through a different path to the supervising station, if the return path is busy.
