Definition of T1?

[Karen G. Schneider]

Before you hit reply--I know how fast a T1 line is and what it does.  (Same
for T3.)  I have been through two paper dictionaries and seven online
acronym dictionaries, and I cannot determine what the "T" in "T1" means.
(One acronym dictionary suggested the T stands for "Telephony," and I could
buy that, but it accepted definitions from just anyone and I didn't think
that qualified as a definitive source.)  

You would think that a resource touting its abilities to decipher acronyms
would at least apologize if it doesn't identify the entire meaning of a
term, but you would be thinking like a librarian.  <grump>
