Hi,
I am having a 3825 as a Voice Gateway. My PRI to the provider is shown as down in "show controllers e1" output. Also in the show isdn status it is shown as LAYER 1 DEACTIVATED.
I suspected the problem with the provider, but the he claims everything is working fine. He even connected on PRI phone to this PRI line and was able to make calls in & out.
My card is VWIC-MFT-2E1. I am pasting the show version, show running and show controller configuration. Please help to resolve this issue.My IOS version is 12.3(14)T7

Hi Manu ,
check how much voltage you are getting in PRI line with multimeter....
Thanks,

Thanks for the reply. What is the normal voltage for the PRI and BRI ?
Thanks,
Manu

Hi Manu,
Voltage check makes no sense for ISDN. You have likely a cabling problem because you receive no signal. Check again the pinout for your card, if the circuit is balanced / unbalanced.
Note the PRI telephones do no exist, your provider may have used a test device, but not a phone. Call him again to make the correct cable so the circuit can be used.

Hi Manu,
Just see how many Line Code violations and Path Violations are there on the interface / controller card.
I'm sure this is an L-1 issue, I would go ahead and do the following:-
1. Clear the counters and see if the numbers do increase.
2.Check the cabling from the demarc to the Router
2. Check the Ground connectivity on the Router
3. Change the Controller Card and check if the err are still there or not.

Hi,
I used to have the same problem. Just check it out:
hope the thread help you to solve this problem.
Regards.

Hi Manu,
I'm sure you've checked this already: -
Are there any alarms on the NTE?
If you have multiple presentations (Ethernet, X21 & Coax), check provider has configured the NTE for the correct one
You should have alarm lights on, try putting a loop on the NTE with a physical cable and seeing if they go out
The above might work
Regards
