T1 went down.

By nm692v ·
Ok, here is the deal. The t1 line was working correctly as of Friday. Stay gone all weekend, did nothing to the network or the cisco 1841-2 router, and copput, nothing. The only thing i get is the csu/dsu remote alarm light.
Anyone know a quick fix?

Have you

Have you contacted the provider of the T1? They should be able to test it remotely to see where the issue is. It may be in the CO and not on your end.

CMiller is right

Alarm on the CSU/DSU makes this pretty straightforward. So if the CSU/DSU is plugged directly into the smart-jack, then short of a bad patch cable, the problem is in the smart-jack or upstream, so would require the provider to diagnose and fix.

If you're going through an extended demarc, then just verify connectivity from the CSU/DSU to the smart-jack/demarc and call the provider.
