'Refuse to acknowledge'? I confused, do you mean the W1 port doesn't go to
established after you have reset it?

So this one line has had continuing problems? Is it PPP or frame relay?
What is the router on the other end of the link?

Framing errors indicate line problems. I'm not sure how a CSU means line
quality, maybe you can fill me in on that aspect.

What CSU/DSU are you using?

Periods of silence? Do you mean no traffic through the W1 port as
indicated by the input and output counters on the W1 port?

If you are getting framing errors, then there is most likely a line
problem.

I'm not sure what you mean by a problem with the ablity to reset the
port? What are you expecting the command to do and what are you seeing?
Maybe I can explain or fix the problem.
