Hi,

We are getting the following errors from time to time:

What I've read over this mailing list and elsewhere, it is mostly due to a
hardware error.

Is there a way to check the hardware errors?  Like, to see the line error,
bit error, crc error of the E1 line?  That would help us in debugging
transmission related issue.
