Trying to copy it from
harhan.org is painful at best.
If you want it to be less painful, buy me a T1 subscription (would have to be
from WorldCom/UUNET, I have a Class C NET from them and
I won't give it up) and
a sync serial card for either VAXBI bus or Q22-bus that
can handle it.

The fastest you can get on Qbus is the DSV11. That can almost
handle 1Mb/s (it fails when fed a constant stream of minimal
length HDLC frames so it was rated at 256kb/s - the next
lower useful speed).
On BI you have either the DMB32 (64kb/s max) or the DSB32.
I forget how fast the DSB32 can go, it might be able to
reach 256kb/s (possibly only on a single port though) but
I'm pretty sure it won't do T1 speeds. The DSB32 is also
not an option if you have a VAX 7000 (although I think
the DMB32 will work in a VAX 7000).
I suspect that for T1 speeds you'll be stuck using an
Alpha or possibly a DECnis, but you'll have to check
that they will cope before you (or your T1 benefactor)
rush out and buy either of those solutions.

This is interesting. Why then do DECvoice and Fallon FAX cards, for a
Qbus VAX, have connectors for a T1 line on them? Not being very
familiar with telephone equipment with T1 lines, perhaps I'm
overlooking something. Any thoughts on this?

These treat the T1 as 24 separate voice channels rather than one data
pipe.
