There seems to be some uncertainty in what "T1" service constitutes.
I am hoping someone out there could detail all the "T1" and T1 related
services offered by the TELCOs.  I.e., what is "DS1" and how does
it relate?  When can one get unstructured 1.544 MB/s bit streams
(the one with 1's alternating polarity and 1's density constraints),
and when does one have to conform the the 24 channel multiplexing
scheme used for voice and lower speed data?

To: human-nets%MIT-OZ@MIT-MC.ARPA, telecom@BBNCCA.ARPA,

     Does anyone know if any work is underway somewhere to develop an
online directory of all electronic mail users and addresses?  The
online directory of Arpanet/Milnet users at SRI-NIC provides a model
of what I have in mind.  It would be most helpful if the NIC directory
were expanded to include the electronic addresses of users of MCI
Mail, Easylink, Compuserve, The Source, Delphi, Bitnet, Usenet, and
other computer networks, and made generally available.  A directory of
all electronic mail users in the world would in fact probably fit
handily on one or two laser disks.  These disks could be updated
monthly, and widely distributed to local nodes and perhaps even to
individuals.  One might enrich this tool with a natural language
interface for searching the directory, and some software which would
know the best (if any) route to send mail from one node to any other
node on any net.

     This is a product which is begging to come into existence.

I am sure the folks at the CSNET-CIC will soon reply, but the
main problem with nameservers is getting the initial data and
keeping the database updated. The NIC uses site liaisons (and
the directory is inaccurate, although pretty good), the CSNET
nameserver has individuals maintain their own entries (unfortunately
there are fewer than one would like). On ARPANET most sites
support "finger" a protocol which allows you to ask a site
for a persons mail id (you have to know the site).

Concerning 212A and 212AR data sets:

The 212A is an unregistered version of that type of
data set, and the 212AR is a registered version of that type of
data set.  The changes are so minimal that the FCC
allows you to use a 212A as a maintnenace-only replacement for a
212AR.  In other words, you can't use a 212A in a new
installation, but you can use it in case your 212AR goes on the
fritz.
