CMTS is a network device in the cable headend.

A node is a outdoor device hanging on the strand from the utility pole or in a ground mounted pedestal. Again it converts the signals from the optical cable to the hardline RF cable.

A single CMTS can connect to 10s or 100s of nodes. 10s or 100s of homes are serviced by 1 node.

Nodes don't show up in trace routes from cable customers, CMTSs do.

A node can't be overloaded, a CMTS can.

A node doesn't sync with a modem, a CMTS does.

A node carries the full bandwidth signal being broadcast to a neighborhood. A CMTS just handles the upstream and downstream data channels needed for cable modems to connect.

There are many other differences.

Got it. THere's a more technical name for a node though right?
