The [[International Packet Switch Stream]] (IPSS) was an international network service, based on the X.25 standard, launched by the international division of BT. This venture was driven by the high demand for affordable access to US-based database and other network services. A service was provided by IPSS to this market, which started operation in 1978. IPSS was later linked to PSS and other packet switched networks around the world using [[Gateway (telecommunications)|gateways]] based on the [[X.75]] standard.

IPSS was interconnected with SATNET.<ref>{{cite journal |last=Hauben |first=Ronda |year=2004 |title=The Internet: On its International Origins and Collaborative Vision |url=http://www.ais.org/~jrh/acn/ACn12-2.a03.txt |journal=Amateur Computerist |volume=12 |issue=2 |access-date=May 29, 2009}}</ref> [[JANET]] connections were available via IPSS.<ref>{{Cite book |last1=Earnshaw |first1=Rae |url=https://books.google.com/books?id=xy7LadoXUVYC&pg=PA46 |title=Digital Convergence - Libraries of the Future |last2=Vince |first2=John |date=2007-09-20 |publisher=Springer Science & Business Media |isbn=978-1-84628-903-3 |pages=46 |language=en}}</ref>
