Check the cable connections between the ADSL port and the wall
jack. The ADSL LED on the rear panel of the router should be on.
Check VPI, VCI, type of encapsulation and type of multiplexing
settings are the same as what you collected from your ISP.
Restart the router. If you still have problems, you may need to verify

with caution.
10Base-T
It is an Ethernet standard for Local Area Network (LAN). 10Base-T uses a twisted p air 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.
ADSL
Asymmetric Digital Subscriber Line, as its 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 connect s two or more physical networks and forwards p a cket s 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.
Default Gateway (Router)
Every non-router IP device needs to configure a default gateway’s IP address. When the
device sends out an IP packet, if the destination is not on the same network, the device has
to send the packet to its default gateway, which will then send it out towards the destination.
DHCP
Dynamic Host Configuration Protocol, this protocol automatically gives every computer on
your home network an IP address.
DNS Server IP Address
DNS stands for Domain Name System, which allows Internet servers to have a domain
name (such as www.Broadbandrouter.com) and one or more IP addresses (such as
192.34.45.8). A DNS server keeps a database of Internet servers and their respective
domain names and IP addresses, so that when a domain name is requested (as in typing
"Broadbandrouter.com" into your Internet browser), the user is sent to the proper IP
address. The DNS server IP address used by the computers on your home network is the
location of the DNS server your ISP has assigned to you.
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.
Ethernet
It is a standard for computer networks. Ethernet networks are connected by special cables
and hubs or switches, and move data around at up to 10/100 million bits per second
(Mbps).
FTP
File Transfer Protocol. The Internet protocol (and program) used to transfer files between
hosts.
Idle Timeout
Idle Timeout is designed so that after there is no traffic to the Internet for a pre-configured
amount of time, the connection will automatically be disconnected.
ISP
Internet Service Provider is a business that provides connectivity to the Internet for
individuals and other businesses or organizations.

ISP Gateway Address
The ISP Gateway Address is an IP address for the Internet router located at the ISP's
office.
LAN
Local Area Network is a group of computers and devices connected together in a relatively
small area (such as a house or an office). Your home network is considered a LAN.
MAC Address
MAC stands for Media Access Control. A MAC address is the hardware address of a device
connected to a network. The MAC address is a unique identifier for a device with an
Ethernet interface. It is comprised of two parts: 3 bytes of data that corresponds to the
Manufacturer ID (unique for each manufacturer), plus 3 bytes that are often used as the
product’s serial number.
MTU
Maximum Transmission Unit
NAT
Network Address Translator is defined by RFC 1631. Enable a LAN network 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. Using the
router’s NAT capability, you can access the Internet from any computer on your home
network without having to purchase more IP addresses from your ISP.
Port
Network Clients (LAN PC) uses port numbers to distinguish one network
application/protocol over another. Below is a list of common applications and protocol/port
numbers:
Application Protocol Port Number
Telnet TCP 23
FTP TCP 21
SMTP TCP 25
POP3 TCP 110
H.323 TCP 1720
SNMP UCP 161
SNMP T rap UDP 162
HTTP TCP 80
PPTP TCP 1723
PC Anywhere TCP 5631
PC Anywhere UDP 5632

PPP
PPP is the 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 data grams 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.
Protocol
A protocol is a set of rules for interaction agreed upon between multiple parties so that
when they interface with each other based on such a protocol, the interpretation of their
behavior is well defined and can be made objectively, without confusion or
misunderstanding.
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.
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.

Subnet Mask
A subnet mask, which may be a part of the TCP/IP information provided by your ISP, is a
set of four numbers (e.g. 255.255.255.0) configured like an IP address. It is used to create
IP address numbers used only within a particular network (as opposed to valid IP address
numbers recognized by the Internet, which must be assigned by InterNIC).
TCP/IP, UDP
Transmission Control Protocol/Internet Protocol (TCP/IP) and Unreliable Datagram
Protocol (UDP). TCP/IP is the standard protocol for data transmission over the Internet.
Both TCP and UDP are transport layer protocol. TCP performs proper error detection and
error recovery, and thus is reliable. UDP on the other hand is not reliable. They both run on
top of the IP (Internet Protocol), a network layer protocol.
TELNET
It is 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 is 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 is part of the ATM cell header. A VPI is a pipe for a number of Virtual
Circuits.
WAN
Wide Area Network is a network that connects computers located in geographically
separate areas (e.g. different buildings, cities, countries). The Internet is a wide area
network.
Web-based management Graphical User Interface (GUI)
Many devices support a graphical user interface that is based on the web browser. This
means the user can use the familiar Netscape or Microsoft Internet Explorer to
Control/configure or monitor the device being managed.
