I know that is the right way to do it...but at my HS, for example, they ran the T1 lines from the demarc to the computer room using regular 25 pair phone cable...nothing special, no separate binders or anything, and it works fine. This is a pretty good distance too. Actually, the lines come into the building in the electrical room, then are sent to a protector where the phone system is, and then out. It's a weird setup.
