First, keep in mind that the built-in ISDN on a PD5000 is 1 B-channel
only and does not have a built-in NT1 (I think). Second, the PD5000
shipped with a sticker covering the jack so you wouldn't know it was
there - it was never supported under Ultrix. The rumor I heard was
that DEC fubared the hardware design and found out too late that it
wouldn't work - that could be BS though. I also heard it's the same
interface chip as the Sparcstation LX used, if you want to research more.
It's been awhile since I ran BSD on my DECstations, but I remember that
OpenBSD detected the device as existing - not sure if it ever could do
anyting with it.
I personally suspect that the answer is "no". I used to admin a bunch
of those in the heyday of Ultrix, and I never saw nor heard of anyone
making a productive use of that jack. Even if you could make it work
just for hack-value, a 64K ISDN interface isn't really that exciting.
