Do you have both ends setup with "Current clock source is line". If you do,
change one end to internal. If both are set to line and telco is not
providing you clocking, the T1 won't come up. I'm more concerned with the
fact that you have down/down. As stated below, you usually get an up/down
with good local cable connection. Is the T1 coming in on a SmartJack (NIU)?
If you can find it (should be labeled with the circuit ID), check the LEDs,
there should be an equipment light and a network light depending on the
vendor.

Check your cable one more time, and make sure it's a straight-through cable
to
the telco demarc (Cat 5 568A or B, or any other 1-1 2-2 ... 8-8 RJ-45 type
cable will work okay in a pinch)
You should at least be able to get up/down status if the cabling is correct.
Also, make sure telco has actually activated the circuit (that they don't
have
it looped back on their end...although the internal CSU should have detected
that)
Finally, are you sure you're plugged into the correct CSU interface on the
router and at the demarc? ;-)
Let us know when you get DCD up :-)
