The short answer is no, not yet. PRI was under trial for a year or so
(it kept being delayed by you-know-who's AXE software), and was
formally introduced last August.

Telecom has announced "BRI" for mid-1990, as a "supplementary service"
wherein a PRI will be demuxed into 14 2B+Ds in a local exchange. Just
how much this will differ from true BRI, I don't know, but I have to
spend some time soon finding out. I guess the mux will have to sort
out the SAPIs, TEPIs, etc.

Exactly. The applications I am looking at for ISDN involve using it
for WANs, as either a replacement for modems and DDS NTUs, or as a
standby to back-up our 2.048 M services. This is why I would like some
TAs, either to go on separate BRIs or to go on our P(A)BX. There *is*
a demand for ISDN phones, provided they supply this sort of wide area
data connectivity.
