t1 installed but not up - urgent

Hello,
I hope some experts are out there over Memorial Day weekend.  Verizon installed a point to point t1 circuit today.  I have two cisco 2621 routers with WIC-1DSU-T1 cards.  Verizon says they can loop the CSU/DSU's on both ends.  However, the router at the host site has both the CD and AL lights on.  Verizon says they provide no clocking on the circuit.  I originally had one side (hub_router) set up as 'clock source internal', but changed it as reflected below to see if that would work.  

I haven't checked the remote site configuration yet, but the routers did communicate successfully when connected via a t1 crossover cable.  The remote router is set up the same as the host site, with the original exception of the clock source. I have not tried any sort of looback tests as I am not familiar enough yet with those commands.     I had a professional install all the cables, so hopefully that is not an issue.  

Any suggestions would be greatly appreciated as the remote is a new location and we want to do business there (retail) over this weekend.  Thank you in advance.

perhaps verizon can assist by testing each point Dmark?

wyatt3Author Commented:
doesn't the fact that they say they can successfully loop the CSU/DSU mean that they are getting past the dmark (smartjack)?  With the Verizon tech on this end, I did watch the lights on the smartjack go to 2 green and 2 amber which he told me was the normal 'up' state for the card.  Verizon doesn't get a lot of points from me on how they handled the entire install.  It took them 3 days to get where we are now.

just had to clarify that, it's OK to say, but really requires that double/triple check...

If you can connect to your router as you mentioned..then router configuration is the only thing left on your plate.

and it's Memorial Day weekend and you caught me with a beer in hand....

What kind of cable do you have between the router's DSU module and the smartjack? It should be a good, tested, CAT5 patch cable. Had virtually the same issue the other day where the building maintenance ran the cable and didn't terminate one end correctly.

>ip default-gateway 10.0.0.1
Remove that line. Your own interface is not your gateway, and this should be handled by a different command:
  ip route 0.0.0.0 0.0.0.0 10.0.0.2

>  DCD=down  
Means it can't see the smartjack at all. Points to cable issue.
Else, it is not a full T1, but a fractional T1 and you have not made the channel assignements.
Default is set to use all 24 channels-
  interface serial 0/0
   service-module T1 timeslots 1-24 <== you won't see default settings with 'show config'  

>they say they can successfully loop the CSU/DSU
But your DSU can't see the smartjack, so how are they looping it?

I visited the remote site this morning.  One smartjack light is green if AMI and amber if b8zs.  The light is green.
At the host site (hub_router) side, the corresponding light is amber (b8zs).  Also, the esf/sf light is not lit at all.
Is this an indication that Verizon has the circuit set up incorrectly?  I will be calling them.

Irwin SantosComputer Integration SpecialistCommented:
Perhaps confirm the configuration of your WIC-1DSU-T1 in the 2621...if it is in the same scope of connectivity and the simple thing of lights NOT matching...that call to Verizon would be prudent.

Turns out to have been a Verizon problem.  The circuit came up Sunday evening.  Something like 2 circuits with same id and/or bad wiring on their end.  It's hard enough to know what is happening outside the cloud, let alone inside it.  
What is the proper way to end this question?  I appreciate both people responding (especially over the holiday weekend) as I had no where else to turn.  I would like to give some points.  I read the help sections on this site but am unsure if 'accepting' one of the answers above is best or if there is a more preferred procedure.
