Abstract

In a communications network including local and central nodes interconnected by terrestrial communications links, said central nodes being also interconnected via satellite links, originating nodes check and reserve a path across the network before transmitting data. Erroneous satellite data is repeated via terrestrial links. In a situation where connection is made to an X-25 computer and to a polled line, the network strips off the user protocol and only transmits that part of the information which represents usable data to the polled line. When the transmission is received back from the output port, appropriate protocol is reinserted, and it therefore appears to the external connections as if they are directly connected to each other.
