Plug a work station directly from the router if it has a built in CSU,
to a work station and skip the hub for now....and test it out...
If the eth is down, make sure the main connection is there, and
conencted, or call the ISP and see if the right routes have been routed
to you...
Check the CSU stats, check the smart jack, and have you been routed?
or get a loob back cable in the router and see if you can ligh tup the
interface
is it a T1? do u need a CSU?
