Subject: Re: WAN Port wigs-out
Dennis:
Well, it looks like there's more comming out of the woodwork with this
problem. We've seen it here and are currently working with Livingston to
figure it out. The guy at the other end of the line from the one that
first gave us trouble had seen it before also, which is how we knew not
to bother calling the phone company again.
I thing you'll find that it works fine if you disconnect the buss cable
from the main board which goes to the other 2 10 port boards. You should
also be able to make it go crazy by pingin it with pattern "ff". What
made me do that was that it was having more problems with binary file
transfers and image files. Looks like lots of bits on give it trouble.
We are waiting for our rep at one site to reconnect the other 20 ports
so we can retest the unit with 3.1.4 (which Brian uploaded to the unit
the other day). We'll see if that does anything.
My personal guess is that it's a hardware problem, either ringing on
the data bus due to termination problems or problems with the drivers at
the WAN port or supply impeadance feeding those drivers. When we pinged
that unit with "ff", you'd see the first 4 to 6 characters come bach
trashed, then the rest would be OK.
I'll let you know what happens here.
