I just got some propaganda mailed to me from PSINet, which included a nice
two page spread of their worldwide network backbone.. and there are only
three sat links on the whole thing.

Breakdown of major longhaul connections for the USA:

Three TransPacific OC3 to OC12 connections.
Porland OR - Tokyo
SanFran CA - Tokyo
San Louis Obispo CA - Tokyo by way of Honolulu

Three transpacific OC96's (OC192 compatable, they call it Dark Fiber)
SanFran CA - Tokyo (x2)
Porland OR - Tokyo

One Transpacific DS1 to OC12
SanFran CA - Hong Kong

Two Transatlantic OC3 to OC12 connections.
New York NY - London (x2)

One Transatlantic DS1 to OC12
Washington DC - Amsterdam

--sats--
Three satellite links
Los Angeles CA - Santiago Chile
Hefndan ?? - Panama
Hefndan ?? - Belo (something) Brazil

They don't mention the bandwidth of the sat links, but I -really- doubt
they're anywhere close to the bandwidth of an OC12..

Here's a breakdown of those various links and bandwidths.

(OC stands for Optical Channel.. i.e., Fiber. I guess you were right Tz. ;)
DS0: 64kilobits/sec
DS1 (T1): 1.54megabits/sec
OC3 (Not T3. A T3 is a DS3.): 155.52megabits/sec
OC12: 622.080megabits/sec
OC48: 2.488gigabits/sec
OC96: 4.976gigabits/sec
OC192: 10gigabits/sec

To nitpick once more and set people straight, even though it's pointless
since industry has adopted the term.. there is really no such thing as a
"fractional T1." All DS circuits are just multiple channel DS0's.. ;)

makes you so sick at heart, that you can't take part; not even tacitly take
part, and you have to throw yourself on all the gears and all the levers
and you have to make it stop."
