I respectfully disagree. We have seen on every PA-MC-* we use anywhere in the country that a hot signal from any Adtran OC3-DS3 mux gear will cause constant LCVs until we add 10-12db of attenuation on the receive side. Once this is done, all of the LCVs go away for good. I don't know that is his problem here, but when a hard loop shows good, I suspect a bad card or a LBO/attenuation issue. -Robert Tellurian Networks - Global Hosting Solutions Since 1995 http://www.tellurian.com | 888-TELLURIAN | 973-300-9211 "Well done is better than well said." - Benjamin Franklin _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
