Overview The modem provides you with high-speed data communications over the television cable network by following the widely accepted DOCSIS/MCNS standards being developed by the Multimedia Cable Network System (MCNS) consortium. Those standards offer a combination of high performance and interoperability among many of the cable system operators in North America. How does a cable modem work? 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. A cable 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, USB port 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 10BASE-T Ethernet connection and USB connection used in this Cable Modem are emerging as the most popular means of connecting a Cable Modem. The new DOCSIS standard may change this in the future. But for now, a 10BASE-T Ethernet or USB must be ready in your computer for the Cable Modem to work.

6

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.

Glossary 10BASE-T Unshielded, twisted pair cable with an RJ-45 connector, used with Ethernet LAN. “10” indicates the speed (10 Mbps), “Base” refers to baseband technology, and “T” means twisted pair cable. Cable TV Coax Cable that allows wide bandwidth transmission over long distances. Coaxial cable (coax) comprises an inner conductor surrounded by insulation. An outer conductor wraps around the insulation, which, in turn, is covered by an outer plastic covering. Ethernet card A plug-in circuit board installed in an expansion slot of a personal computer. The Ethernet card (sometimes called a Network Interface Card, or NIC) takes parallel data from the computer, converts it to serial data, puts it into a packet format, and sends it over the 10BASE-T LAN cable. F connector A type of coaxial connector, labeled RF on the rear of the Toshiba Cable Modem, that connects the modem to the cable system. Headend The equipment, in the central office of the service provider, where the cable signals originate. Hybrid Fiber/ Coaxial (HFC) system A system where the trunk of the cable plant is of fiber technology. Somewhere near the subscriber’s home, the fiber is connected to a coaxial cable, and the signal is converted so that it’s compatible with the fiber media. The coaxial cable then runs through the branches of the network and is finally dropped into the home. HUB A device used to connect multiple computers to the cable modem. Internet A collection of interconnected networks used for worldwide computer-based communications. IP Address A unique, 32-bit address assigned to every device in a network. An IP (Internet Protocol) address has two parts: 1) a network address and 2) a host address. Each network is assigned an address by a government agency, and each company administrator assigns an address to each host computer.

18

Modem registration The process the Toshiba Cable Modem uses to make itself known to the headend equipment. Once authorized by the router, the modem is assigned upstream and downstream channels for data communication. Network driver A (software) file included with the Ethernet card. The file is loaded on the computer to allow the computer to recognize the Ethernet card. See Ethernet Card. RJ-45 Connector on the Toshiba Cable Modem, labeled 10BASE-T, that connects the modem to a computer or to a HUB. Subscriber A computer user in the home who accesses a data service using the Toshiba Cable Modem. Subnet A network subdivision. When subnetting us used, the IP (Internet Protocol) address is divided into a subnet number and a host number. Hosts and gateways identify the bits used for the network and subnet number through the use of a subnet mask. TCP/IP communication stack Software in the subscriber computer

that processes packets through the

communication layers. The subscriber configures the IP address for the computer and the router default gateway in the software. The TCP/IP communication stack handles all the communications with the subscriber’s application. USB Universal Serial Bus, standardized for easy connections between the PC and the other peripherals. USB connects more than computers and peripherals.
