How does the cable modem work?
Cable modems are very different from the standard analog modems that we are so accustomed to. Cable modems operate, as their name suggests, by MOdulating and DEModulating Cable transmission signals. However, they are much more complex than a standard analog modem in that they are part router, part bridge and part tuner. Cable Modems also act as an Ethernet hub. Picriverisp.net’s state-of-the-art headend unit, specially equipped with servers, monitors and transmitters, receives the transmission of high-bandwidth data from the Internet, through Bell Global’s fiber optic Network. The data packets flow into Picriverisp.net’s servers, and are then transferred through Cable to the customer’s home. The customer’s cable modem receives the high-speed transmission, and the Ethernet card translates the data to your computer.
Instead of a computer modem hooked up to a local phone line, Road Runner customers will be provided with a high-speed cable modem that links their computer to the cable fiber-optic/coaxial network and Regional Data Center. Users can access local news, entertainment information and other local content from various computer servers throughout their local area. These servers also provide a gateway for Road Runner customers to connect to the Internet, at very high speeds.
The modem is connected on one side to an Ethernet on your computer. The other side of the cable modem is connected to the Thames Valley Communications cable outlet on the wall. The cable modem works like an addressable cable converter box and is “tuned” to select the Internet data channel. The data to and from your PC travels over the Internet data cable channel on the Thames Valley Communications fiber optic network to the Thames Valley Communications headend and Internet gateway.
