Could well be from noise ingress - lots of work goes into finding & fixing ingress issues. Hard to say unless we look in detail at the connection in question and the neighborhood node.
Packet loss absolutely could be noise ingress. That's measurable in terms of s/n ratio and it's on the outside plant HFC side. But noise doesn't "build up", and PoE is DC, and PoE is on the LAN side, separated from Comcast's equipment by a router. Level 1 Comcast guy is simply wrong. -- Jay Hennigan - jay@west.net Network Engineering - CCIE #7880 503 897-8550 - WB6RDV
