Now I'm thinking that the "T" in "10BaseT",
"100BaseT4", etc. and the T the line capacities "T-1", "T-2",
etc. are the same thing. Is that true?
Maybe. The 'T' in "10baseT" etc is the same 'T' as in
"UTP" -- unshielded
twisted pairs. I don't know what the 'T' in "T1" stands for. It
might be
the same as one in "AT&T" since they coined the term, or it might mean
"twisted pair" because that's how T1 lines were originally made. T1, BTW,
is 1.544Mb/s, and T3 is 44.736Mb/s; AFAIK there's no such thing as T2. A
bit like ISDN; there's ISDN2, ISDN6, ISDN30, but no others.
And is there a "10BroadT"? :)
Nope.
