Well that answers it Joe, I use sb5100, sb5120 and arris cm 550, I bet all modems are similar as these you looked at. Funny nobody at Ibbs noc knew this,they should have known this, would have saved me a good bit of aggrivation,on the other hand I should have known also. Well at least now we do,the 105 mgz freq is working out well,all modems back up and running.
