Role of ISDN signaling for a satellite system with on-board processing

The onboard processing (OBP) system, as currently being developed by the European Space Agency, ensures full satellite/ISDN compatibility for worldwide ISDN service operation. The authors present various arguments for opting for the international standard ISDN signaling scheme, propose several alternatives for effective interworking between different applications supported by the OBP system, and address an efficient method to transport DSS1 through the satellite system and to meet CCITT delay performance objectives for end-to-end connections.<
