They are pretty much the standard for Verizon and most other large telcos and for a good reason. Their stuff is good. I'd encourage them to run 25 pair minimum. The cable costs a tiny bit more, but the protection options that offer telco-grade standards start at the 25 pair count. Just make sure that any protection hardware meets BellCore (Telecordia) standards and you'll be fine. Ed Vaughn, MBSWWYPBX

How many people will work out of it? I'm a pessimist I'd go 50 pair. Forty six years and still fascinated with Telecommunications!
