Re: How's does it all really work?

said by keo eke:
I only see ONE headend in Mac's diagram and 4 hub sites.
The diagram is a very general representation of an HFC (read type needed for DOCSIS modems to work) network. Its not specific to any one cable company or area. Nothing I posted earlier is specific to any Adelphia system.

Its all very general "How cable modem networks work" type stuff.

Yeah, we're slightly different here than that diagram...

We have one headend, feeding over 700 nodes. Each node feeds one active. It's called "Node Plus One" architecture. You don't have all those cascading amps to worry with!

(we don't miss the cascades at all!)
