Hal -

PSets were NOT the same. There were 4 different varieties that I knew of - AT&T, Northern, Fujitsu and.....I can't remember the 4th (I sound like Rick Perry). We got them at the end of my time on the job when we could no longer get AT&T 20 button models.

But while the new ones (whatever they were) were compatible with AT&T, Northern Tel wasn't (and vice versa). Fujitsu claimed compatibility - but I never had a chance to test it out.

ISDN was a stop-gap technology (like DSL), just designed to hold the fort until something better came along.

It's old and dead and we should all be glad. It was a pain in the ass.
