Cable router
Appearance
"Cable router" has two basic meanings:
- Single Cable Router (SCR) - a down-conversion device for the radio data link. It converts RF signal from a satellite dish or TV antenna to the user-defined IF channel. Usually, many SCRs are connected to a single coaxial cable - each converting to a separate IF channel. The entire system referred to as Single Cable Distribution.
- A piece of computer network equipment located between cable modem and LAN, performing functions of the network router in a modem.
Cable routers are usually integrated with the modem, frequently incorporating firewall, proxy, or network gateway functions as well.
