Pioneering Ubiquitous Home Network: Silicon Solutions Phone Line Networking
introduction AMD's first home networking controller will change consumers interact with their personal computers. AMD's single-chip controller fully compliant with Home Phoneline Networking Alliance's (HomePNA) initial specification Mbps data transfer over standard telephone wiring. Utilizing widely endorsed HomePNA technology leveraging significant expertise enterprise networking allows produce highly-integrated device capable meeting growing consumer demand inexpensive, easy-to-use technology allowing sharing computing resources among many different PCs. PCnetTM-Home single-chip controller marries Ethernet with in-home telephone wiring deliver promises home networking.
INTRODUCTION
While Local Area Networks (LANs) well-accepted part communications environment businesses, LANs commonly deployed home. This several technical logistical reasons. Chief among these fact that widely adopted supported enterprise networking technologies require technically skilled individual capable designing maintaining complex network architecture. Enterprise networks also require high-grade wiring typically found most homes. Also, home users willing master installing maintaining Ethernet repeater, learn even basics about network protocols, drill holes through their walls network-capable wiring throughout their home. driving force behind creating home connectivity products growing number homes with more PCs. With increased focus computers education boom Internet connectivity, large number being purchased today additional opposed replacement units. Today, estimated that over million million homes United States have more PCs, consumer purchases families that already have least computer. This number expected double year 2000 according research firm Dataquest. growth number multiple-PC households leads need connecting these order maximize benefits peripheral components have convenient method sharing files other information between various computers within home. home with multiple PCs, each computer would ideally have printer, scanner other
required peripheral. With home network, multiple users share these expensive peripherals, regardless their location throughout home. Without network, users want print file, cannot afford have printer attached every home, must physically move file from another floppy disk. With networked PCs, applications files easily shared users, saving time money. additional primary requirement home network ability provide direct access Internet from every within home. Distributing Internet access throughout home becomes increasingly important next-generation access technologies such cable modems UADSL services deliver increasing amounts bandwidth side home. Today, when multiple home users want access Internet separate PCs, they must each their telephone line either share single Internet account set-up multiple accounts. Neither these solutions ideal, result often multiple users must share Internet access serial fashion-one time. Home networks deliver huge savings enabling shared access single Internet connection. With integrated silicon software support, home network enable external gateway, distributing Internet access every device network simultaneously. Multi-player games will also benefit from widespread adoption home networks, enabling gamers located nearly anywhere home compete against another. ubiquitous, easy-to-install home network will also foster home automation applications that take advantage network environment, such environmental control security systems (see Figure

AMD, leader highly-integrated Ethernet networking silicon, founded alliance with other companies designate, promote support home networking technology that uses existing in-home telephone wiring connect peripherals. HomePNA technical specification currently supports transmission data Mbps across existing phone wiring, without interfering with standard voice transmissions. AMD's home networking silicon device enables creation low-cost Network Interface Cards (NICs) adapters that seamlessly connect PCs, printers, remote access routers, scanners, other peripherals home network.
ronment designed meet these requirements. First foremost, home networking solution uses existing in-home telephone wiring does require installation additional wiring. With PCnet-Home controller, every RJ-11 modular phone jack home become port LAN. PCs, peripherals, network devices installed single network that span feet between farthest points. PCnet-Home controller uses Frequency Division Multiplexing approach that enables standard telephone wiring simultaneously carry voice, Universal ADSL home networking signals without services impacting each other. Signals from home networking device centered 7.5Mhz, with signal ranging between 5.5Mhz 9.5Mhz. shown figure below, this range well above frequencies used voice services (POTS) Universal Asynchronous Digital Subscriber Line (UADSL) services (see Figure

This dual functionality allows single controller support both standard Ethernet networking well HomePNA network standard, creating that complete Ethernet home network node integrated into single device. based this singlechip controller approach uses Windows 95/98 Network Driver Interface Specifications (NDIS) stacks, does require additional software drivers enable home network. This significantly decreases time market issues also ensures home networking support native operating system. Additional silicon functionality enabled through integration interface unit, Direct Memory Access (DMA) Buffer Management Unit, ISO/IEC 88023 (IEEE 802.3) compliant MAC, Transmit FIFO large Receive FIFO. This additional on-chip functionality serves foundation creating compelling, easy-to-use home networking solution. Media Independent Interface (MII) allows direct connection additional external PHY, such Mbps enable Fast Ethernet support. This high level integration silicon level enables compelling inexpensive HomePNA built that meets consumer price/performance requirements successful home networking solution. enables additional ease-of-use features silicon level well. instance, AMD's innovative any1Hometechnology simplifies network management indicating when valid node been detected. any1Home packet uses minimal network resources detect network failure, allowing upper layer protocols take action correct potential conflicts that compromise network performance.
