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?

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. -- Wayne McGuire <wayne%mit-oz@mit-mc> ------- ------------------------------ Date: Wed, 20 Feb 85 09:04:36 pst From: adrion%ucbingres@Berkeley (Rick Adrion) To: MDC.WAYNE%MIT-OZ@MIT-MC.ARPA, human-nets%MIT-OZ@MIT-MC.ARPA, Subject: Re: Electronic Mail Directory Cc: zbbs%MIT-OZ@MIT-MC.ARPA 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). ------------------------------ From: ihnp4!drutx!rkp@Berkeley Date: 20 Feb 85 11:23:45 CST (Wed) To: ihnp4!cbosgd!ulysses!ucbvax!telecom@Berkeley Subject: Re: TELECOM Digest V4 #161 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. Russell Pierce AT&T Something or Other...
