Then you'll need to hook up a modem at the demarc and wait for it to sync. Plug the modem into the test jack temporarily. If it doesn't sync within a couple of minutes, try another circuit in the NID (if there are additional circuits installed). Assuming the circuit has been installed correctly, then the modem should sync up. You could also bring along a laptop and verify you have the correct circuit by checking for internet access.

When I was doing contract DSL installations for a CLEC a couple yrs ago, I often times had the circuit ID on the workorder. If (and a very big IF) the LEC did their job, they tagged the circuit and tested the circuit. I also had a Colt-250+ test tool to test unlabeled circuits. Once I found sync, I called into the CLEC NOC and asked them to check the interface on the DSLAM to make sure I had the correct circuit and not some other CLEC's circuit.
