PPPoA
Point-to-Point Protocol over ATM 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.
PPPoE
Point-to-Point Protocol over Ethernet 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.
protocol
A set of rules governing the transmission of data. In order for a
data transmission to work, both ends of the connection have to
follow the rules of the protocol.
remote
In a physically separate location. For example, an employee
away on travel who logs in to the company’s intranet is a remote
user.
RIP
Routing Information Protocol The original TCP/IP routing
protocol. There are two versions of RIP: version and version II.
RJ-11
Registered Jack Standard-11 The standard plug used to connect
telephones, fax machines, modems, etc. to a telephone jack. It is
a 6-pin connector usually containing four wires.
RJ-45
Registered Jack Standard-45 The 8-pin plug used in transmitting
data over phone lines. Ethernet cabling usually uses this type of
connector.
routing
Forwarding data between your network and the Internet on the
most efficient route, based on the data’s destination IP address
and current network conditions. A device that performs routing is
called a router.
rule
See filtering rule, NAT rule.
SDNS
Secondary Domain Name System (server) A DNS server that can
be used if the primary DSN server is not available. See DNS.
SNMP
Simple Network Management Protocol The TCP/IP protocol
used for network management.
splitter
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.

splitterless
A type of DSL installation where no splitter is installed, saving
the cost of a service call by the telephone company. Instead, each
jack in the home carries both voice and data, requiring a
microfilter for each telephone to prevent interference from the
data signal. ADSL is usually splitterless; if you are unsure if your
installation has a splitter, ask your DSL provider. See also splitter,
microfilter.
subnet
A subnet is a portion of a network. The subnet is distinguished
from the larger network by a subnet mask which selects some of
the computers of the network and excludes all others. The
subnet's computers remain physically connected to the rest of
the parent network, but they are treated as though they were on a
separate network. See also network mask.
subnet mask
A mask that defines a subnet. See also network mask.
TCP
See TCP/IP.
TCP/IP
Transmission Control Protocol/Internet Protocol 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 with
higher-level applications such as HTTP, FTP, Telnet, etc., TCP/IP
refers to this whole suite of protocols.
Telnet
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.
TFTP
Trivial File Transfer Protocol.
A protocol for file transfers, TFTP
is easier to use than File Transfer Protocol (FTP) but not as
capable or secure.
TTL
Time To Live A field in an IP packet that limits the life span of
that packet. Originally meant as a time duration, the TTL is
usually represented instead as a maximum hop count; each
router that receives a packet decrements this field by one. When
the TTL reaches zero, the packet is discarded.
twisted pair
The ordinary copper telephone wiring long used by telephone
companies. It contains one or more wire pairs twisted together to
reduce inductance and noise. Each telephone line uses one pair.
In homes, it is most often installed with two pairs. For Ethernet
LANs, a higher grade called Category 3 (CAT 3) is used for
10BASE-T networks, and an even higher grade called Category 5
(CAT 5) is used for 100BASE-T networks. See also 10BASE-T,
100BASE-T, Ethernet.
upstream
The direction of data transmission from the user to the Internet.

USB
Universal Serial Bus A serial interface that lets you connect
devices such as printers, scanners, etc. to your computer by
simply plugging them in. The My ADSL Modem is equipped
with a USB interface for connecting to a stand-alone PC.
VC
Virtual Circuit A connection from your ADSL router to your ISP.
VCI
Virtual Circuit Identifier 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. See also VC.
VPI
Virtual Path Identifier Together with the Virtual Circuit Identifier
(VCI), the VPI uniquely identifies a VC. Your ISP will tell you
the VPI for each VC they provide. See also VC.
WAN
Wide Area Network Any network spread over a large geographi-
cal area, such as a country or continent. With respect to the My
ADSL Modem, WAN refers to the Internet.
Web browser
A software program that uses Hyper-Text Transfer Protocol
(HTTP) to download information from (and upload to) web sites,
and displays the information, which may consist of text, graphic
images, audio, or video, to the user. Web browsers use Hyper-
Text Transfer Protocol (HTTP). Popular web browsers include
Netscape Navigator and Microsoft Internet Explorer. See also
HTTP, web site, WWW.
Web page
A web site file typically containing text, graphics and hyperlinks
(cross-references) to the other pages on that web site, as well as
to pages on other web sites. When a user accesses a web site, the
first page that is displayed is called the Home page. See also
hyperlink, web site.
Web site
A computer on the Internet that distributes information to (and
gets information from) remote users through web browsers. A
web site typically consists of web pages that contain text,
graphics, and hyperlinks. See also hyperlink, web page.
WWW
World Wide Web Also called (the) Web. Collective term for all
web sites anywhere in the world
that can be accessed via the
Internet.
