Unlike regular dialup phone service, ADSL provides continuously available, "always on" connection. ADSL is asymmetric in that it uses most of the channel to transmit downstream to the user and only a small part to receive information from the user. ADSL simultaneously accommodates analog

(voice) information on the same line. ADSL is generally offered at downstream data rates from 512 Kbps to about 8 Mbps, upstream data rates up to 1Mbps. ADSL was specifically designed to exploit the one-way nature of most multimedia communication in which large amounts of information flow toward the user and only a small amount of interactive control information is returned. 5 A D S L M o d e m M a n u a l V isionNet 708 Layout and LED Description VisionNet 708 (Front view) 6 A D S L M o d e m M a n u a l Location L a b e l S t a t u s D e s c r i p t i o n POWER VisionNet 708 power status Its On when VisionNet 708 is connected to PC which is working.

Also known as Category 5 (CAT 5) wiring. See also data rate, Ethernet. A D S L Asymmetric Digital Subscriber Line The most commonly deployed "flavor" of DSL for home users. The term asymmetrical refers to its unequal data rates for downloading and uploading (the download rate is higher than the upload rate). The asymmetrical rates benefit home users because they typically download much more data from the Internet than they upload. A T M ( A s y n c h r o n o u s T r a n s f e r M o d e ) Asynchronous Transfer Mode A standard for high-speed transmission of data, text, voice, and video, widely used within the Internet. ATM data rates range from 45 Mbps to 2.5 Gbps. See also data rate. B r i d g i n g Passing data from your network to your ISP and vice versa using the hardware addresses of the devices at each location. Bridging contrasts with routing, which can add more intelligence to data transfers by using network addresses instead. The [Productname] can perform both routing and bridging. Typically, when both functions are enabled, the device routes IP data and bridges all other types of data. See also routing. D N S ( D o m a i n N a m e S y s t e m ) The DNS maps domain names into IP addresses. DNS information is distributed hierarchically throughout the Internet among computers called DNS servers. When you start to access a web site, a DNS server looks up the requested domain name to find its corresponding IP address. If the DNS server cannot find the IP address, it communicates with higher-level DNS servers to determine the IP address. See also domain name. 45 A D S L M o d e m M a n u a l D H C P ( D y n a m i c H o s t C o n f i g u r a t i o n P r o t o c o l ) automates address assignment and management. When a computer connects to the LAN, DHCP assigns it an IP address from a s hared pool of IP addresses; after a specified time limit, DHCP returns the address to the pool. E t h e r n e t The most commonly installed computer network technology, usually using twisted pair wiring. Ethernet data rates are 10 Mbps and 100 Mbps. See also 10BASE-T, 100BASE-T, twisted pair. F T P ( F i l e T r a n s f e r P r o t o c o l ) A program used to transfer files between computers connected to the Internet. Common uses include uploading new or updated files to a web server, and downloading files from a web server. I P a d d r e s s ( I n t e r n e t P r o t o c o l a d d r e s s ) The address of a host (computer) on the Internet, consisting of four numbers, each from 0 to 255, separated by periods, e.g., 209.191.4.240. An IP address consists of a network ID that identifies the particular network the host belongs to, and a host ID uniquely identifying the host itself on that network. A network mask is used to define the network ID and the host ID. Because IP addresses are difficult to remember, they usually have an associated domain name that can be specified instead. See also domain name, network mask. I S P ( I n t e r n e t S e r v i c e P r o v i d e r ) A company that provides Internet access to its customers, usually for a fee. P P P o A ( P o i n t- t o - P o i n t P r o t o c o l o v e r A T M ) One of the two types of PPP interfaces you can define for a Virtual Circuit (VC), the other type being PPPoE. You can define only one PPPoA interface per VC. P P P o E ( P o i n t- t o - P o i n t P r o t o c o l o v e r E t h e r n e t) One of the two types of PPP interfaces you can define for a Virtual Circuit (VC), the other type being PPPoA. You can define one or more PPPoE interfaces per VC. 46 A D S L M o d e m M a n u a l P O T S ( P l a n e O l d T e l e p h o n e S e r v i c e ) Traditional analog telephone service using copper telephone lines. Pronounced "pots." See also PSTN. T C P / I P ( T r a n s m i s s i o n C o n t r o l P r o t o c o l / I n t e r n e t P r o t o c o l ) The basic protocols used on the Internet. TCP is responsible for dividing data up into packets for delivery and reassembling them at the destination, while IP is responsible for delivering the packets from source to destination. When TCP and IP are bundled wi th higher -level applications such as HTTP, FTP, Telnet, etc., TCP/IP refers to this whole suite of protocols. T e l n e t An interactive, character-based program used to access a remote computer. While HTTP (the web protocol) and FTP only allow you to download files from a remote computer, Telnet allows you to log into and use a computer from a remote location. R o u t i n g Forwarding data between your network and the Internet on the most efficient route, based on the datas destination IP address and current network conditions. A device that performs routing is called a router. W W W ( W o r l d W i d e W e b ) Also called (the) Web. Collective term for all web sites anywhere in the world that can be accessed via the Internet. S p l i t t e r A device that splits off the voice component of the DSL signal to a separate line, so that data and telephone service each have their own wiring and jacks. The splitter is installed by your telephone company where the DSL line enters your home. The CO also contains splitters that separate the voice and data signals, sending voice to the PSTN and data on high-speed lines to the Internet. See also CO, PSTN, splitterless, microfilter. 47 A D S L M o d e m M a n u a l P P P ( P o i n t - t o - P o i n t P r o t o c o l ) A protocol for serial data transmission that is used to carry IP (and other protocol) data between your ISP and your computer. The WAN interface on the [Productname] uses two forms of PPP called PPPoA and PPPoE. See also PPPoA, PPPoE. V C I ( V i r t u a l C h a n n e l I d e n t i f i e r ) Together with the Virtual Path Identifier (VPI), the VCI uniquely identifies a VC. Your ISP will tell you the VCI for each VC they provide.
