of one other Calix shop in Iowa that had an ongoing IP video issue and it was
also resolved by replacing the OC-48 card, a card that didn’t have any
visible issues.<o:p></o:p></span></p>

in, so I would think that doesn’t cross the OC-48 cards, but who knows,
maybe it does.<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>We
had the exact issue three weeks ago with a Calix ring. No errors anywhere
in the path, the issue affected ADSL, VDSL and FTTH customers, all but one node
was affected. It turned out being a bad OC-48 card that showed NO ERRORS,
NO NOTHING for days, however, the problem was going on for several days,
intermittent and hard to "catch" at first and then it was almost
continuous for about 12 hours. I had Calix TAC in the network and they
spent about four hours taking logs and reading numbers and could not point at
anything. Then finally the guy suggests to start swapping out OC-48 cards
one at a time until the problem cleared.....it only took swapping out five
different cards... :-(</span><o:p></o:p></p>
