I wish you would know what you are talking about.

Good for you, most people don't have it this way.

Really???? Digium cards in such a setup *do have problems* (ask Digium
the will tell you the same), while a working channel bank if it works
*does not* have problems.

So why do phone companies not stick to a pair a copper for each line?
why do they use fiber lines?

So get the experience, by crying I don't have the experience you will

Well it's actualy easier with a T1, since there is only one line to
check, while with your 3 TDMs you  have to first find the pair.

Hmmmmmm, so you telling me that for wiring the TDMs you use pre
crimmped wires even when using 12 runs? you outa go to wiring school
as well, why don't you use a 66 or 110, it's much neater, and easier
to expand, move, or change.

Looks like you don't know eBay (you even mispelled it).

Exactly, because you havn't got a clue about wiring, you shouldn't be
touching phone systems at all.
