Hello,
can you try and change the framing to ´no crc-4´ and back to ´crc-4´ ? That can sometimes help in bringing the controller up.
Assuming that you are trying to configure voice support, make sure your IOS version supports the voice (the IOS image has a ´v´).
Can you post the entire config of your router, as well as the output of ´show version´ ?

Hi
In addition to GPs post would suggest to check up by looping at ur remote end and check whether your are getting clean and errorfree loop.since your alarm specification is also mentioning "Far End Alarm Detected"..

Hello,
one thing that I was windering is which network module you are using ? Keep in mind that the VWIC-2MFT-E1-DI is only supported with the NM-2W and the NM-HDV module.

Yes its NM_HDV.
Thanks.

Hello,
your config looks ok, you could try and configure linecoding b8zs, so instead of:
controller E1 1/0
framing crc4
linecoding hdb3
clock source line
pri-group timeslots 1-31
you would configure:
controller E1 1/0
framing crc4
linecoding b8zs
clock source line
pri-group timeslots 1-31
If nothing else helps, physically check the cable to the provider modem, and you also might want to reset the modem, if possible.
The controller also has a command 'cable length', which should match the actual cable you are using.
Of course there could always be a problem with the provider line itself, who is your provider ?
