As you know, digital signals are represented by high and low electrical voltage levels. And how fast these levels can switch and still be transmitted is determined by the "bandwidth" of the transmission system. The pair of wires used in a telephone connection have greatly limited bandwidth, because of their electrical characteristics. So what we do is connect a device called a modem between the computer output and the phone line. The modem generates an electrical wave whose strength and phase change in step with the highs and lows of the computer's digital output. It's because of the
"smoothness" of the resultant signal that a higher data rate can be transmitted. Acable modem MOdulates and DEModulates electrical signals in the same sense that the telephone modem does. However, since coaxial cable can carry much higher wave frequencies, cable modems are far more sophisticated. Their internals can include a tuner, a bridge, a router, an encryption/decryption device, an SNMP agent and an Ethernet hub. Furthermore, none of the activity caused by these circuits and codes disturbs your regular cable TV reception. How does a cable modem connect to a computer?
The 10BaseT Ethernet connection used in this Cable Modem is emerging as the most popular. This connection has been used for years to allow business computers to talk to each other in a LAN (Local Area Network). The new DOCSIS standard may change this in the future. But for now, an Ethernet card must be installed in your computer for the Cable Modem to work. What is DOCSIS?
Data Over Cable Service Interface Specifications. DOCSIS defines interface requirements for cable modems involved in high-speed data distribution over a cable television network. On November 17, 1997, Cable Television Laboratories, Inc. (Cable Labs) and its members established a formal path of certification for cable modem equipment suppliers to obtain an interoperability seal for their products based on the DOCSIS specification. This certification process provides cable modem equipment suppliers with a fast, market-oriented method for attaining cable industry acknowledgment of compliance with DOCSIS. The seal is meant to provide the purchaser with a way to be confident that the modem equipment to be purchased is compliant with the specification, and that the equipment interoperates with DOCSIS products made by other vendors. What equipment do I need to use a Cable Modem?
- A cable operator that provides the MCNS high-speed data service
- AComputer (the Cable Modem is platform independent so it does not matter what kind)
- Astandard 10BaseT Ethernet connection (installed in your computer) Page 7 TurboComm DOCSIS Cable Modem Users Manual Can I still watch cable TV while using Cable Modem?
Yes, you cable wire is split at your home so both may be used at the same time. Can I have cable modem service but not subscribe to cable TV?
Yes, you may have one, or both. How much faster is Cable Modem connection than other internet connections. The Cable Modem connection is many times faster than other internet connections. Cable Modem is transfer data in bursts and the maximum downstream data rate is 40Mbps. However, in the field, you can mostly you can have 4 ~ 10Mbps steady downstream data flow. Take a 1OMB file download time as an example.
