Can anyone on the list tell me why I might start seeing the Rx light on a HiperArc change from green to Orange and red...? I would assume that it indicates MAJOR collisions, but can't figure out why I am now seeing it. The HiperArc is only carrying about 30 calls on the rack and this does not happen all the time. Could it be a Dialup USER that is "flooding" the connection? Is there someway I can track this behavior down? This is a QUAD hub. THe other Quad hub is not displaying this behavior and it is ALWAYS full! Thanks in advance! I am hoping that this is not an indication of the card getting ready to fail <GRIN> Phillip ------------------------------------------------- WebMail Services Provided By WorldNet Access
