An initiative for conformance ATM-networks relying on satellite-links

This paper presents the preliminary results of an initiative, supported by three public network operators (PNO)s-Telefonica, Swiss Telecom PTT and Telia-and the EUTELSAT organisation. The physical and ATM layer tests were carried out both in the laboratory and via a satellite. During the field trials, the measurements were performed at the earth station and through ATM nodes. Multimedia services experiments were conducted to demonstrate the feasibility of ATM networks based on satellite links(for B-ISDN bearer services) and to further investigate the impact of some satellite-specific impairments, such as bursty errors and link delay, on the service performance.
