SemiOT: Network HW items

?? OK, I don't know much about higher speed setups. I know ISDN is kinda outdated and slow now, but what is currently available at what speeds/costs and how are they setup? Rather OT I suppose. But more towards the quote above, what really would be needed to setup a T1? And how fast IS a T1(something I probably used to know but forgot a while ago since I don't run across them often)? The older TSU/CSU/DSU/Whatever-SU's(not only is my memory bad, but I can't seem to think straight right now!) seem to show up a lot at surplus stores or in junk piles. Any reasons to grab or avoid them? -- /------------------------------------\ | http://jrollins.tripod.com/ | | KD7BCY kd7bcy(a)teleport.com | \------------------------------------/
