Hello Raju,

I would get with my provider, the output indicates that the remote end is sending faulty frames.

You might want to check this document:

Thanks GP. I had escalated this issue to service provider and they said that MUX connected with our RAS at their end hang up sometimes and it needs to be restarted. Thanks for sending this link.
