Hi,

what model of router is this?

did you tried an OIR ?

I have seen this happening when OIR is not supported, so a reload of the box is needed.

or when having a faulty card.

please send more details of the issue, like show version, and steps applied to this card so far.

regards

Yesua.

Hi  Yesua,

                   The router is 3825 running ios ver Version 12.4(1c), config i believe is correct..

I not remove or insert the module..

The RA led is amber, could it be the remote side down?

Thanks

Take "show controllers E1".

Most likely, bad cable or circuit failure.
