FAQ, list archives,
I remember looking at a link on Cisco's web site that stated an acceptable
threshold for CRC errors on an interface. I believe it was something like
CRCs could not exceed .001% of the total input packets on the interface.
Has anyone else seen this link, or one like it? I am trying to determine

On shared Ethernet, CRC errors are often the result of a collision. Let's
leave that aside, however, and assume that you are referring to CRC errors
on full-duplex Ethernet or serial links. CRC errors are caused by noise,
signal reflections, impedance mismatches, improperly installed demarcs

This isn't the case here, because if I get them around the wrong way,

Hi All,
I have a 2MB leased line (UK Megastream) line between two sites.
One site has a 3640, the other a 2621.
The line is presented as G703 both ends.
I have PDA DC2020 G703 to X21 converters at both ends.
so connection is:

I have experienced a similar problem using G703 cards in a cisco 2620, in
