There is a US patent on it, sealed in 1989, but is it patented in any
other countries? There is no such thing as a "global patent" - patents
only cover the country which issues them. There is a global patent
application process (the Patent Co-operation Treaty), but that just
establishes a priority date for the invention in each country, but the
inventor still needs to file patent applications and have them approved
(sealed)  is each and every country. Did Bellcore do that back in the 1980s?
