Re: Finding old ISDN PRI terminals?
Yes I've only come across ISDN PRI stuff in 'commercial' gear - PBX and what in the 1990s was expensive Corporate-quality videoconferencing.
It was a bit-of-a-thing a couple of decades back as a way to replace a 'snake' of analog copper lines into a small-business or a radio-station but they generally got decommissioned [along with the 2b+d basic 64K ISDN circuits to 'outlier' studios] once "Metro Ethernet" became cheap.
