Well, the local companies are starting to offer what here in NJ is called
"Class Calling Service" -- part of which is a hack to identify the calling
number [Caller*ID service].  It costs money and you need a decoder box to
display the digits.  The details on how the protocol works, I'm told, are
available in various Bellcore technical bulletins:

	TR TSY 000030 -- customer premis data interface, or some such
	TR TSY 000031 -- calling number delivery
	TR TSY 000032 -- bulk calling number ID  [?]

These things are available from your nearest Bellcore but cost money, like
$25 per TR or so.  I am this close to stopping by the local office and picking
them up, because we'll eventually have these services here too and I'm
interested in building a decoder box for it [another Interesting Project
for the list], but it's relatively low priority at this point, so I'm not
sure when I'll get the chance to go get the TRs.  Has anyone else gone out
and fronted the bucks yet and can provide more details??  Rumor has it that
it's done via a 212-modem-like signal between the first and second ring,
but that's all I know about it.
