Whoa. Gandalf.
I worked on one of those once and it was craaaaay-zee. Customer bought
one, and I had to get it to interoperate with an Ascend 400. It took a
lot of fiddle-farting, but I did eventually get it to work.
Fun times.

I don't know about the other ILECs out there, but I don't know if Verizon will
even provision a T1 anymore. I know you can still get a PRI (that's how our
phone systems interface with the PSTN), but if we needed a CT1 instead, I don't
know that they'd be able (willing) to deliver it. I know you can't get a BRI.
We moved offices a few years ago and we basically lost the ability to use our
STEs for anything but voice as we couldn't get BRIs delivered to the new space.
Speaking of ISDN, I had equipment that would support 56k ISDN, but never saw it
provisioned (was that Switch56? Or am I mixing up FR and ISDN?). All of the
ISDN circuits I dealt with were standard 2B+D (BRI), or 23B+D (PRI). I think
the oldest (and weirdest) piece of gear I personally worked on was a Gandalf
ISDN router that was supporting a US Navy site to site connection. Which makes
me a newcomer to The Internet compared to a lot of people on this list, I'm
sure.
