I know nothing about iOS.  I set this used 2600 up about five years back following a recipe and it has been worked fine until a power outage today.

On my Serial0/0 interface the Status and Protocol are both down.  Going into config and typing
 interface Serial0/0
 no shutdown
 end

doesn't change this state.  

I am at a loss on where or how to proceed.  Any help would be much appreciated.

Will it come up if you loop it back on itself?

I don't know what that means -- is this jumping the wires back to each other on an ethernet cable?  Which pins would I short?

OK, found the look back button on the DSU card.  I pushed it, the status changed to "up".  Pushed it again, status changed to "down".

T1 could be dead at the other end. Call your provider.

Provider insists that it isn't, and that they were getting a positive loop-back test on the smart jack on the end of the telco equipment -- they're insisting the problems in on my end.

Run a few "show" commands and post them.  

show interface s0/0

sh run interface s0/0

It appears that your hardware was not damaged in the power outage (Surge).





While in Enable Mode, type the following command. show run. This will give you the running config of your router. You should see a bunch of information in regards to your Serial Interface 0/0. If there is nothing there your router has lost it's configuration.



The link I posted above will give you an idea of what you should be seeing.



Is your T1 line powered or is it plugged into an AC outlet? Possible that it got fried. If AC powered, and your router interface config looks good, get your provider on the phone and request that they test it again to a Hard Loop. That will confirm if the back plane of the NIU/Smart Jack is good.

Configuration is there and correct.

The router and card is definitely OK?  I'm not sure how to argue the point with the provider (Cogent), when they are positive that they are getting a good signal.

Config looks good.



Call your provider and request they test to a Hard Loop.

Were is the NIU (smart jack) located?  Do you have extended cabling from a Dmarc?
Check and make sure you don't have a cabling issue.  Yes I know it worked fine before, you would be surprised how many times I've had cables go bad.

Westell NIU card has PWR, LB, and ESF lights on.  I'm not sure that LB is always on or not.  For giggles, picture below.

MOTHER FUCKERS.

Cogent was running a loop back test the entire time.... and even after the equipment started responding, they failed to drop the test.

All is up and running again.  Thank you, everyone, for the help.

Yup doesn't mean the cable has water in it or had lightning damage.

LB -- "Loop back".  The loop back light was on.

And I said "hey, is this yellow light supposed to be on?" and the initially just brushed it off.  Five fucking hours ago.

I believe that NIU can be set-up to go into loopback if power is lost.
