Do you have a Pre-wired 66 block, or a hand punched 66 block? Usually the first pair at the top of a pre-wired block is the first analog line. But if someone made a mistake, or the telco cable is bad that could be part of it. The last thing I would try is in the manager, under resources_telephony try disable and then enable again. It may see it that way. But honestly it sounds like cabling. Make sure the cross connect is on the right pins, and you may have left out the jumper in the middle of the block.
Another thought if all above is correct. Did you put the CO lines in the line pool A? or other. And do you have a route in dialing plan? You can even test a single set by clicking on line 61, that add a set to that there. It will get a dial tone out.
