Network Address Translation (NAT)
Network Address Translation (NAT) allows the translation of an Internet protocol address used within one
network (for example a private IP address used in a local network) to a different IP address known within
another network (for example a public IP address used on the Internet).
Universal Plug and Play (UPnP)
Using the standard TCP/IP protocol, the ADSL2+ Router and other UPnP enabled devices can dynamically
join a network, obtain an IP address and convey its capabilities to other devices on the network.
10/100M Auto-negotiation Ethernet/Fast Ethernet Interface
This auto-negotiation feature allows the ADSL2+ Router to detect the speed of incoming transmissions and
adjust appropriately without manual intervention. It allows data transfer of either 10 Mbps or 100 Mbps in
either half-duplex or full-duplex mode depending on your Ethernet network.
Dynamic DNS Support
With Dynamic DNS support, you can have a static hostname alias for a dynamic IP address,
Multiple PVC (Permanent Virtual Circuits) Support
Your ADSL2+ Router supports up to 8 PVC’s.
DHCP Support
DHCP (Dynamic Host Configuration Protocol) allows individual clients (computers) to obtain TCP/IP
configuration at start-up from a centralized DHCP server. The ADSL2+ Router has built-in DHCP server
capability enabled by default. It can assign IP addresses, an IP default gateway and DNS servers to DHCP
clients. The ADSL2+ Router can now also act as a surrogate DHCP server (DHCP Relay) where it relays IP
address assignment from the actual real DHCP server to the clients.

7.0 Technology Glossary
10Base-T
An adaptation of the Ethernet standard for Local Area Network (LAN). 10Base-T uses a twisted pair
cable with maximum length of 100 meters.
AAL
ATM Adaptation Layer that defines the rules governing segmentation and reassembly of data into
cells. Different AAL types are suited to different traffic classes.
Address mask
A bit mask used to select bits from an Internet address for subnet addressing. The mask is 32 bits
long and selects the network portion of the Internet address and one or more bits of the local portion.
Sometimes called subnet mask.
ADSL
Asymmetric Digital Subscriber Line, as it’s name showing, is an asymmetrical data transmission
technology with high traffic rate downstream and low traffic rate upstream. ADSL technology
satisfies the bandwidth requirement of applications, which demand “asymmetric” traffic, such as
web surfing, file download and Video-on-demand (VOD).
ATM
Asynchronous Transfer Mode is a layer 2 protocol supporting high-speed asynchronous data with
advanced traffic management and quality of service features.
bps
Bits per second. A standard measurement of digital transmission speeds.
Bridge
A device that connects two or more physical networks and forwards packets between them. Bridges
can usually be made to filter packets, that is, to forward only certain traffic. Related devices are:
repeaters which simply forward electrical signals from one cable to the other, and full-fledged
routers which make routing decisions based on several criteria.
CPE
Customer Premises Equipment, such as ADSL router, USB modem.
DHCP
Dynamic Host Configuration Protocol. Used for assigning dynamic IP address to devices on a
network. Used by ISPs for dialup users.
DNS
Domain Name Server, translates domain names into IP addresses to help user recognize and
remember. However, the Internet actually runs on numbered IP addresses, DNS servers needs to
translate domain names back to their respective IP addresses.
DSL
Digital Line Subscriber (DSL) technology provides high-speed access over twisted copper pair for
connection to the Internet, LAN interfaces, and to broadband services such as video-on-demand,
distance learning, and video conferencing.

15
ADSL2+ Route
r
FTP
File Transfer Protocol. The Internet protocol (and program) used to transfer files between hosts.
IPoA (RFC 1577)
Classical IP and ARP over ATM. Considers ATM configured as a Logic IP Sub-network(LIS) to
replace Ethernet local LAN segments.
ISP
Internet service provider. A company that allows home and corporate users to connect to the
Internet.
LAN
Local area network. A limited distance (typically under a few kilometers or a couple of miles)
high-speed network (typically 4 to 100 Mbps) that supports many computers.
MAC
Media Access Control Layer. A sub-layer of the Data Link Layer (Layer 2) of the ISO OSI Model
responsible for media control.
MTU
Maximum Transmission Unit
NAT
Network Address Translator as defined by RFC 1631. Enables a LAN to use one set of IP address
for internal traffic. A NAT box located where the LAN meets the Internet provides the necessary IP
address translation. This helps provide a sort of firewall and allow for a wider address range to be
used internally without danger of conflict.
PPP
Point-to-Point-Protocol. The successor to SLIP, PPP provides router-to-router and host-to-network
connections over both synchronous and asynchronous circuits.
PPPoA (RFC 2364)
The Point-to-Point Protocol(PPP) provides a standard method for transporting multi-protocol
datagrams over point-to-point links. This document describes the use of ATM Adaptation Layer 5
(AAL5) for framing PPP encapsulated packets.
PPPoE (RFC 2516)
This document describes how to build PPP sessions and encapsulate PPP packets over Ethernet.
PPP over Ethernet (PPPoE) provides the ability to connect a network of hosts over a simple
bridging access device to a remote Access Concentrator.
PVC
Permanent Virtual Circuit. Connection-oriented permanent leased line circuit between end-stations
on a network over a separate ATM circuit.
RFC
Request for Comments. The document series, begun in 1969, which describes the Internet suite of
protocols and related experiments. Not all RFCs describe Internet standards, but all Internet standards
are written up as RFCs

16
ADSL2+ Route
r
RFC 1483
Multi-protocol encapsulation over AAL-5. Two encapsulation methods for carrying network
interconnect traffic over ATM AAL-5. The first method allows multiplexing of multiple protocols over
a single ATM virtual circuit. The protocol of a carried PDU is identified by prefixing the PDU by an
IEEE 802.2 Logical Link Control (LLC) header. This method is in the following called "LLC
Encapsulation". The second method does higher-layer protocol multiplexing implicitly by ATM
Virtual Circuits (VCs). It is in the following called "VC Based Multiplexing".
Router
A system responsible for making decisions about which of several paths network (or Internet) traffic
will follow. To do this, it uses a routing protocol to gain information about the network and algorithms
to choose the best route based on several criteria known as "routing metrics.
Spanning Tree
Spanning-Tree Bridge Protocol (STP). Part of an IEEE standard. A mechanism for detecting and
preventing loops from occurring in a multi-bridged environment. When bridges connect three or
more LAN segments, a loop can occur. Because a bridge forwards all packets that are not
recognized as being local, some packets can circulate for long periods of time, eventually degrading
system performance. This algorithm ensures only one path connects any pair of stations, selecting
one bridge as the 'root' bridge, with the highest priority one as identifier, from which all paths should
radiate.
TELNET
The virtual terminal protocol in the Internet suite of protocols. Allows users of one host to log into a
remote host and act as normal terminal users of that host.
VCI
Virtual Circuit Identifier. Part of the ATM cell header, a VCI is a tag indicating the channel over which
a cell will travel. The VCI of a cell can be changed as it moves between switches via Signaling.
VPI
Virtual Path Identifier. Part of the ATM cell header, a VPI is a pipe for a number of Virtual Circuits.
WAN
Wide area network. A data communications network that spans any distance and is usually provided
by a public carrier (such as a telephone company or service provider)
