Your new WLAN DSL router is a fully-equipped, high performance
router. What purpose does a router actually fulfill?
To answer this question, we must first consider how data is exchanged or transferred within a network. When copying a file
from a server, for example, the complete file is not put on the
network in one go, but is divided into small packets. Other information, such as a database request, for instance, is also broken
up into such packets.
These packets are transferred according to specific rules, the socalled protocols. Initially each computer manufacturer developed
it’s own protocol. Exchange between different protocols was only
possible with the help of special devices. Thanks to the success of
the Internet, the TCP/IP protocol family became obligatory for all
manufacturers, even for use within local networks.
Your data is accordingly broken down into several IP packets and
carried over the local Ethernet. So that the individual packets arrive at the correct recipient, each packet is provided with sender
and receiver information. This information is called the IP addresses and with the help of IP addresses servers and users can
be found within a network. If, however, you want to reach a
server on the Internet, for example a web page, it will usually not
be located in your local network. This is where a router comes
into play. It is the job of a router to connect your computer (or
network) to the remote servers. To do this, the router transmits
the single IP packets from the local network over DSL or 56k modem to the public Internet. Based on the IP address, the router
determines whether an IP packet should stay within the network
or whether it needs to be re-routed. In such cases, the router
establishes a connection via 56k modem or DSL to your Internet
provider – also called Internet Service Provider (ISP) – who in
turn transfers the packets to the Internet. The Internet provider
charges for this service and will offer several different tariffs and
billing methods. As soon as the router recognises that an IP
packet is not intended for the internal Ethernet, it logs in to the
ISP and transfers this IP packet to the Internet.

HAT IS A ROUTER?
W
WHAT DOES A ROUTER ACTUALLY DO?
A router connects different networks together. It can route
Ethernet networks, DSL, 56k modem and also wireless networks.
A number of further features have also been built into your WLAN
DSL router:
Firewall
A firewall protects a local network from attacks coming from
outside the network.
DHCP server (Dynamic Host Configuration Protocol)
A DHCP server automatically allocates the IP configuration of clients within a local network. As such, the users do not have to
manually enter their IP address.
DNS server
(Domain Name Server)
A DNS server translates the domain address for accessing a web
page (for example www.medion.com) into a valid IP address.
In the following pages of this user guide we will explain these
functions in more detail. To get started quickly and with no hassle, we recommend you start your configuration with the One-
Click page. As detailed on this page, all you need to enter are the
few details the WLAN DSL router requires to establish a connection to the Internet. In just “one click” this will give you almost
instantaneous high speed access to the Internet and other services.

In the product box you will find the router, which should be connected
to your network as well as to the ADSL line and/or telephone (modem) line. This chapter describes how to easily connect your router.
D
CONNECTING
On the back of your router you will find ports for Ethernet, ADSL
and Modem as well as for the power supply of the device:
Ethernet (LAN) ADSL 56k Power
Modem Supply
Connect your router as follows:
CONNECT YOUR ROUTER TO ADSL
1. Put one plug of the supplied ADSL cable into the ADSL port of
the router.
2. Plug the other end of the ADSL cable into your ADSL splitter
(not supplied). The LED on top of the router next to the DSL
label lights up.
CONNECT YOUR ROUTER TO THE NETWORK
 If you wish to set up a wireless network, please refer to
“Set up in a wireless network” (page 11). However, we
recommend first setting up your router through a computer which is connected to Ethernet (LAN). This will avoid
any difficulty caused through improper security settings.
 Before you connect your router to the Ethernet LAN,
please check if you already use the automatic IP assignment (DHCP server) within your network. Furthermore,
make sure that the pre-configured router IP address
(192.168.0.100) is not already in use within the network.

ETTING STARTED
G
If the above conditions are met, you can connect your router directly to the Ethernet. For further information, please refer to section “Set up in an Ethernet network” (page 9).
If you have a small network, you can connect your DSL router
either to the network adapter of your computer or to a hub. You
have simply to pay attention to the choice of the cable. In section
“Set up in an Ethernet network” (page 9), it is explained under
which circumstances your router is to be connected to a computer
or to a hub.
1. Put one plug of the supplied blue Ethernet cable into the
Ethernet port of your router.
2. Plug the other end of the Ethernet cable into a free Ethernet
port of your computer, or alternatively a network hub.
3. The LED on top of the router next to the LAN label lights up.
CONNECT YOUR ROUTER MODEM
The router’s 56k modem is supposed to be a back-up solution in
case of a missing or non-functional ADSL connection.
1. Put one plug of the supplied modem cable into the Modem
port of the router.
2. Plug the other end of the modem cable into a telephone
socket.
3. The LED on top of the router next to the Modem label lights up.
CONNECT YOUR POWER CABLE TO THE ELECTRICITY MAINS
Use the power supply to connect your router to a mains socket.
 Make sure that you use only the power supply supplied
with your router and ensure that the voltage indicated on
the plug corresponds to your local voltage supply.
You have now finished connecting up your WLAN ADSL router.
SET UP IN AN ETHERNET NETWORK
Whether you should connect your router directly to the Ethernet
port of a computer or to an Ethernet hub depends on your current
network configuration. The two crucial issues are whether automatic IP address allocation (i.e. a DHCP server) or the preconfigured WLAN DSL router IP address (192.168.0.100) are already in use within your network.

 For the DHCP server and client configuration, please re-
fer to the documentation of your operating system. A
short description of the DHCP client configuration can be
found at the end of this manual in section “How do I configure my computer as a DHCP client?” on page 41.
The following questions should help you decide how best to connect your router for the first set up:
Are the client addresses within your network automatically
allocated by an existing DHCP server?
• Yes:
In this case, the router may not perform this function and the
setting “Automatic client addresses” must be set to “No”
in the OneClick page.
• No:
You are free to decide whether the router should assume this
role within your network or not. We recommend using automatic IP address allocation in order to remove the need for
manual administration of the network addresses. In this case,
as the option “Automatic client addresses” is set by default to “Yes”, you should leave this setting unchanged. Make
sure that the networked computers are set up as DHCP clients, enabling them to request an IP address from the DHCP
server upon booting.
Is the router default address “192.168.0.100”
already in use in your network?
• Yes:
In this case, the IP address of your router must be changed.
Connect your router directly to the Ethernet port of a computer (one having a different IP address to that of your
router) and replace the pre-configured IP address with a
valid, free IP address from your network in the OneClick
configuration page. After doing so you can connect your
router directly to the Ethernet hub.
• No:
You can connect your router directly to the Ethernet hub using the supplied cable.

SET UP IN A WIRELESS NETWORK
The wireless function of the router is activated by default. A few
minutes after connecting the device, the “Wireless” LED will light
up and you then have wireless access to your router.
In order to communicate over the wireless network with the
router, your computer has to be equipped with an IEEE 802.11b
or IEEE 802.11g compatible wireless card.
1. Make sure first that the TCP/IP configuration of your computer is set to “DHCP client” and that there is no entry for the
Domain Name Server.
2. Activate now the wireless card of your computer (Please refer
to the documentation of the wireless card or computer). The
router declares itself within the wireless network under the
name “Medion”.
3. Choose “Medion” from the list of the available wireless networks.
4. The WEP encryption is deactivated by default on your router.
5. You can now communicate with the router and proceed to
make any further setting changes, as required.

ROUTER CONFIGURATION
WHICH DETAILS DO YOU NEED FOR THE CONFIGURATION?
Before starting to configure your router, we recommend you have
the following information ready to hand:
- Name of your ADSL Internet provider
- Your personal access details received from your ADSL
Internet provider upon signing up for the service
- A valid, free IP address for your router in case you need to
replace the default IP address.
Before you can start to use your router it must first be configured.
This can be done automatically with the help of the browser interface:
ROUTER BROWSER INTERFACE
The router browser interface enables you to configure your router
and control its activities.
In order to access the pages of the browser interface, enter the IP
address of your router in the address line of your browser application. The default IP address is “192.168.0.100”.
Once the router is successfully found, this Homepage is displayed:

Upon first accessing one of the configuration pages you will be
prompted for the administrator user name and password.
The factory default settings are “admin” as user name and
“admin” as password. Please check your shift/caps lock settings
because the entry is case sensitive:
These settings can be modified in the Administration page.
To move around the configuration pages use either the navigation
bar on the left hand side of the window or simply click on the corresponding element in the main diagram on the Homepage.
The browser interface contains three configuration modes:
• OneClick mode: In this mode you need to enter just the essential settings for your router to give you immediate access
to the Internet. Details of this extremely easy-to-use configuration mode can be found on the next page.
• User mode: Here you can configure the basic settings for
your router, as described on page 17.
• Expert mode: In this mode, experts have access to advanced settings. The various configuration options under this
mode can be found on page 31.
In all modes detailed online descriptions and explanations help
you through the configuration process. These help texts appear

Automatic client address
Within a network all devices must be individually “numbered” and
have their own client address – a so-called IP address. The allocation of these addresses can be automatically carried out by your
router. The advantage being that you do not have to
enter manually the IP address for all the networked devices.
Using the radio buttons, you can activate or deactivate the automatic IP address allocation carried out by the DHCP server incorporated in your router.
• Yes: By default, the automatic IP address allocation is
switched on. Ensure that the networked computers are set up
as DHCP clients. When set as DHCP client, the computer requests an IP address from the DHCP server upon booting.
• No: The automatic IP address allocation is deactivated. Remember to check the IP address management within the
network, as to work properly within a TCP/IP network all devices require unique IP addresses.
Router address
Your router is pre-configured with the IP address 192.168.0.100.
The subnet mask is automatically set to 255.255.255.0 and is not
shown in this mode. Here you can replace the pre-configured IP
address with another, valid IP address.
Apply
Click “Apply” to apply and save the settings in your router. You
will then be returned to the Home page.

further configuration changes as required. If a DHCP server and
automatic IP address allocation are already set-up within your
network, then you must deactivate this function within your
router. The default IP address of your router is 192.168.0.100.
This can be changed in the “Ethernet settings” page should the IP
address already exist within your network.
 Note: If you change the IP address of your router, you
must then login again using the new IP address, in order
to continue your configuration.
Verify
Click “Verify” to test your settings and ADSL line and establish a
connection to the Internet. The following confirmation page lists
the important steps of the login procedure and shows the result of

USER MODE CONFIGURATION
In user mode (not using the OneClick configuration) you can configure the basic settings for your router. The various configuration
options are dependant on your product model and are listed in the
left hand navigation bar. To open the various configuration pages
select the item from the navigation bar or simply click on the corresponding element in the main diagram on the Home page.
ETHERNET SETTINGS
In this window you can configure your local network settings and
determine the behaviour of your router within the network. If
your router does not contain correct settings it will not be found
by the computers within the network.
DHCP server
Every computer in your network – just like your router - requires a
unique IP address. Dynamic Host Configuration Protocol (DHCP)
offers a way of automatically allocating IP client configurations
within your local network. If your router is configured as DHCP
server, then it will automatically allocate an IP address to a client
computer requesting address information within the network. The
client computer broadcasts a request, the DHCP server receives it,
assigns a new address for a specific period of time and sends it to
the client together with other required configuration information.
Your router can be set-up and used as a DHCP server and consequently manages the IP addresses within its TCP/IP network.
ETTING STARTED
G
17
Activate
Your router automatically allocates IP addresses to all networked
devices. The advantage being that you do not have to enter
manually the IP address for all the networked devices.
 By default, the automatic IP address allocation is
switched on. Ensure that the networked computers are
set up as DHCP clients. When set as DHCP client, the
computer broadcasts a request for IP configuration from
the DHCP server upon booting.
Ensure that there are no other DHCP servers within the
network. Should this be the case, you must deactivate
the DHCP server in your router.
Deactivate
The automatic IP address allocation is switched off. Remember to
check the IP address management within the network, as to work
properly within a TCP/IP network all devices require unique IP
addresses.
First router address
The IP address and subnet mask give every device in the network
a unique identification. As default, your router carries the IP address 192.168.0.100. The subnet mask is automatically set to
255.255.255.0. In these fields you can replace the default address with another valid IP address and subnet mask.
 If you change the IP address of your router you must
then login to the router again under this new IP address
in order to continue your configuration.
Second router address
As default your router uses 10.0.0.1 as its second IP
address and 255.0.0.0 as its second subnet mask. Should the
router be connected to a network with two separate address
ranges then you should also enter IP address and subnet mask for
the second network. The router uses the IP address
192.168.0.100 to communicate within the first network address
range and 10.0.0.1 for the second. The subnet mask must also be
defined for both networks.
In these fields you can replace both default settings with another
valid IP address and subnet mask.

- Flat rate:
A flat rate is the ideal tariff for surfers who spend a lot of
time in the Internet or who download large amounts of
data (MP3s, movies, etc.). This tariff is also recommended
for those planning to host an FTP or web server.
- Online time:
Billing charged according to time spent online is best
suited for users who only surf the Internet occasionally.
2. Enter in the field “Shorthold” the time in minutes after
which the connection should be dropped should there be
no activity on the line. This setting only makes sense if
your Internet connection is charged according to time
spent online.

21
Firewall
A firewall protects the local network from unwanted attacks from
outside. Your router contains a so-called ‘Statefull Packet Inspection Firewall’. By default, the router firewall is activated and set to
a medium security level.
The firewall is activated by just clicking on one of the pre-defined
security levels or alternatively, turned off completely. We recommend, however, switching on at least the lower security level.
The ports set in the pre-defined security levels are as follows:
Service Port Description
http 80 World wide web
DNS 53 Domain Name Server
FTP 21 File Transfer Protocol
Telnet 23 Terminal session
SMTP 25 Simple Mail Transfer Protocol
POP3 110 Post Office Protocol Version 3
NNTP 119 Network News Transfer Protocol
ARCP 7070 Real audio & video
ICMP N/A Internet Control Message Protocol (error and

H.323 1720 Video conference
T.120 1503 Whiteboarding (for video conference)
SSH 22 Secure Unix Shell, Remote login protocol
All other ports not contained in this list are blocked by default and
must be set to “Allowed” manually in the Expert Mode.
 For describing the firewall we use the term “service”. In
the context of a firewall, “service” means the request on
a particular port. This request can be initialised from outside or from within the local network. Thereby it is important who the initiator of the request is.
Example: If the outbound “service” for the port http is
allowed, a user within the local network can send an http
request to the outside. He will be returned the corresponding answer to his request, that means, he can surf
the Internet. The inbound “service” for http is blocked
most of the time (exception: webserver); This implies
that http requests coming from outside are denied.

Intruder detection activated
Activating this option automatically delays replies to repeated requests

WIRELESS NETWORK
The wireless LAN module is based on the international IEEE 802.11g
and IEEE 802.11b standards and, as such, this router is compatible with
all current 54 or 11Mbit/s wireless LAN adapters. In addition, the router
supports WEP encryption (Wired Equivalent Privacy).
The router has an integrated bridge and transfers all packets as they
are from the wireless to the cabled network. On doing so AppleTalk
packets are also transferred in Apple networks (e.g. for access of a
wireless computer to a cabled networked AppleTalk printer).
 The wireless module in your router should under no circum-
stances be removed. This may damage your device!
Activated / Deactivated
The wireless function enables you to set up a wireless network.
The router assumes the role of a wireless Access Point. The wireless function in this router is activated by default, but can, however, be deactivated if not required. Once deactivated, the router
no longer broadcasts radio signals and the wireless network cannot be accessed.
 If you are using the router in a wireless network and dis-
able the wireless function, please be aware that you will
no longer be able to access your device using the wireless network after having activated the change. In this
case, you will have to connect your device to the
Ethernet or a computer to access it again.

ETHERNET SET-UP
Every computer in your network – just like your router –
requires a unique IP address. Dynamic Host Configuration Protocol (DHCP) offers a way of automatically allocating IP client
configurations within your local network.
If your router is configured as DHCP server, then it will automatically allocate an IP address from a specified range of addresses to
a client computer requesting address information within the network. The client computer configured as DHCP client broadcasts a
request, the DHCP server receives it, assigns a new address for a
specific period of time and sends it to the client together with
other required configuration information. This has the advantage
that you do not need to manually configure fixed IP addresses for
the clients in your network. This not only reduces the network
administration overhead but also removes any chance of making
mistakes.
You can set an address range for the DHCP server from which the
router takes the IP addresses. The DHCP server also transfers the
ETTING STARTED
G
31
subnet mask as well as the addresses of specified Domain Name
Servers.
Your router can be set-up and used as a DHCP server
and consequently manages the IP addresses within its TCP/IP
network. In this window, you can configure the DHCP server along
with further more detailed Ethernet settings for your router.
DHCP server
Deactivated
The automatic IP address allocation is switched off. Remember to check the IP address management within the
network, as to work properly within a TCP/IP network all
devices require unique IP addresses.
Activated
The router automatically allocates IP addresses to all networked devices set as DHCP client. The advantage being
that you do not have to enter manually the IP address for
all the networked devices.
 By default, the automatic IP address assignment is
switched on. Ensure that the networked computers are
set up as DHCP clients. When set as DHCP client, the
computer broadcasts a request for IP address configuration from the DHCP server on starting.
Ensure that there are no other DHCP servers within the
network. Should this be the case, you must deactivate
the automatic IP address assignment in your router.
32
ETTING STARTED
G
DHCP server settings
So that your router can allocate IP addresses to the client computers in the network, an address range from which it takes the
addresses must be determined.
You have two options for setting the address range:
- The IP addresses can be taken from the default IP address
range, which is set to 192.168.0.101 to 192.168.0.200.
- An address range (starting address and ending address) from
which the address should be taken can be manually set.
When a computer set as DHCP client in the network is started and
requests an IP address, the DHCP server will allocate an address
taken from the specified range. The DHCP server will not reallocate the address during the lease period and will attempt to return the same address every time the client requests an address.
Address range
Check this option if you want the router to use the pre-configured
default address range (192.168.1.2 to 192.168.1.128).
First IP address
Here you can manually set your own address range. Enter in this
field the first IP address of the address range.
Last IP address
Here you can manually set your own address range. Enter in this
field the last IP address of the address range.
If your router is set-up as DHCP server it will also automatically
assign the subnet mask.
Lease time
The allocated IP addresses can only be used for a certain period of
time – the so-called lease time. After this lease time has expired
the client can no longer use the address. So that the client does
not lose its addresses (most importantly its IP address) it requests an extension before the lease time expires. This is usually
granted. The address configuration will only be lost if the lease
time expires whilst the client computer is switched off.
The lease time can be determined using two settings.
Default lease time (in seconds)
Enter in this field the lease time which should be allocated
should the client computer not request a lease time.
The default setting 43.200 seconds represents approximately 12 hours.
ETTING STARTED
G
33
Maximum lease time (in seconds)
Enter in this field the maximum lease time that the DHCP
server can allocate to the client computers.
Even if the client computer requests a longer lease time,
the DHCP server will only grant the maximum lease time.
The default setting 86.400 seconds represents approximately 24 hours.
Gateway
Your router can be used as default gateway. This option is activated by default. As such, the DHCP server will configure the client computers with it’s own IP address as the gateway address. If
required, this setting can be manually over-written in the client
computer settings.
DNS server settings
In TCP/IP networks, the DNS (Domain Name Server) translates
network / domain names to IP addresses. This is necessary for
Internet communication. Every time a domain name (e.g.
www.medion.com) is used, a DNS is used to translate the “human-readable” domain name into a “machine-readable” IP address. Even within a local network or when connecting two separate networks it is advisable to use this in order to uniquely assign
the IP addresses within the network to the particular computer
names. Your router can also be used as a DNS server.
Your router obtains the necessary information from POP
(Point of Presence). This option is activated by default.
1st and 2nd IP address
If you wish to use different, external DNS servers, then enter the
IP addresses in these fields.

GLOSSARY
10Base-T
A 10Mbit Ethernet connection using so-called twisted
pair cable. The cable is technically the same as ISDN
cables used for the telephone network, but usually with
a better shielding.
100Base-T
Also known as Fast Ethernet, 100Base-T uses the same
type of cable as 10Base-T. The maximum theoretical
transfer rate is 100Mbit/s.
802.11 Standard
Industrial standard for wireless networks (WLAN). The
most important variants of this standard are as follows:
802.11b: Maximum data transfer rate 11Mbit/s.
The frequency used is 2.45 GHz. This protocol allows
standard, basic encryption up to 128 bit. This standard
is used worldwide and in most wireless devices.
802.11a: Maximum data transfer rate 54Mbit/s. The
frequency used is 5 GHz. This standard is still relatively
new and not available everywhere.
802.11g: Maximum data transfer rate 54Mbit/s. The
frequency used is 2.45 GHz. This standard is compatible with the 802.11b standard and is used in the Apple
AirPort Extreme product, for example.
Access Point
In a wireless network (WLAN) the wireless connection
is performed by the Access Point. The Access Point enables communication between the wireless devices
and, if used, also with wired devices. The Access Point
can be connected to normal wired devices via Ethernet
as well as to an analogue or digital line via a modem or
44
USTOMER SERVICE
C
a router. In this way it can give the wireless devices
access to further communication lines and services.
ADSL (Asymmetric Digital Subscriber Line)
ADSL technology is one the many types of DSL technology. ADSL stands for Asymmetric Digital Subscriber
Line, i.e. an asymmetrical usage of the line. A significant advantage of ADSL is that existing telephone lines
can be used for providing broadband services without
effecting existing analogue or ISDN connections. The
download/downstream rate (i.e. the transfer speed
from the Internet to your computer) reaches far higher
speeds than the upload/ upstream rate (i.e. the transfer speed from your computer to the Internet). With
ADSL, transfer speeds of up to 8Mbit/s downstream
and 1.5Mbit/s upstream are possible. As such, large
amounts of data can be transferred very quickly. Because ADSL uses very high frequencies, there are limits over the distance that the signal can be reliably received. Most ADSL services have a maximum range of
5.5km – meaning only customers within this radius of
their local telephone exchange can take advantage of
ADSL.
For home users, who as a rule mainly download data
from the Internet, there are several cheaper offers
with lower transfer speeds.
ATM
ATM stands for Asynchronous Transfer Mode and is a
fast packet-oriented transfer and relay technology
widely used to send data, video and voice at ultra high
speeds. ATM is best known for its easy integration with
other technologies and for its sophisticated management features that allow carriers to guarantee quality
of service and data transfer in real time. As such, ATM
USTOMER SERVICE
C
45
is the world's most widely deployed backbone technology and is the preferred medium for applications like
interactive television, video conferencing etc.
Bandwidth
Bandwidth describes the amount of data that can pass
through a line within a certain period of time.
CAT-5 cable
Describes the type of cable used for 10Base-T twisted
pair. CAT-5 cable is suited for 100 MHz and is used in
10Mbit und 100Mbit networks.
Crossover cable
For networking just two computers together a crossover CAT-5 cable is recommended. This makes a direct
connection, send and receive lines are crossed. With
such a connection, a hub is not required.
Data packets
Data sent over a network is broken down into parts of
a certain size in bytes – so-called packets. Each packet
carries the information that will help it get to its destination: the sender’s IP address, the intended receiver’s
IP address, something that tells the network how many
packets the data being sent has been broken into and
the number of that particular packet. An e-mail can,
for example, travel around the world in many separate
packets, arrive in a different sequence and yet still be
recomposed again correctly. Should an error occur during the transfer, the faulty or lost packet must be requested again. This method used in large networks is
very efficient and fast.

DHCP server (Dynamic Host Configuration Protocol)
A DHCP server automatically allocates the IP configuration of clients within a local network. As such, the users do not have to manually enter their IP address.
DNS server (Domain Name Server)
A DNS server translates the domain address for accessing a web page (for example www.medion.com)
into a valid IP address.
Downstream / Upstream
Describes the direction of the data flow to or from the
network.
DSL
DSL stands for “Digital Subscriber Line”. It uses the
standard copper wires that are used to carry telephone
lines into most homes. Theoretically data can be transferred at speeds up to 50Mbit/s.
The higher the frequency that is used to send a signal
over a piece of wire, the faster the signal will degrade
over distance. DSL uses very high frequencies and
consequently there are limits over the distance that
the signal can be reliably received. As such the distance from the telephone exchange is a critical factor.
Due to certain technical conditions (e.g. distance from
the telephone exchange, non-availability of copper
lines, etc.) DSL is not available everywhere.
With DSL, the use of a splitter is required to separate
the voice information and data transfer.
DSL router
A DSL router establishes a connection to the Internet
provider and diverts data within the network so that
several users can share the connection. A router man-
USTOMER SERVICE
C
47
ages all the internal addresses and often also offers
further options and features, such as DHCP, firewall,
etc. Routers are available for various technologies: for
ISDN, analogue, DSL or cable – the basic principle is
the same. If you wish to share a DSL connection between several users, then a router is absolutely necessary. Software routers are also available, which emulate the hardware within the software. In such cases a
small computer is sufficient to assume the role of a
router.
Encapsulation
In the ADSL settings, the encapsulation mode describes the way the Internet packets can be packed to
optimise the transport. According to the chosen protocol (access mode), this can be done in different ways.
Encryption
Encryption of data is used to protect against unauthorised access or line-tapping.
Ethernet
Ethernet was first implemented in 1976 by 3Com and
is today the standard technology for LAN architectures.
Typical Ethernet implementations include 10Base-T,
100Base-T and gigabit Ethernet. Network protocols
coming later, such as TCP/IP, were based on this architecture.
Firewall
Data sent within a network is sent in so-called packets,
which contain detailed information regarding the type
of packet, the sender, the recipient and so on. A firewall can filter out these packets according to certain
specified rules. Firewalls are available in hardware as
48
USTOMER SERVICE
C
well as software form and are often built directly into
routers. Firewalls are mainly used in critical environments to prevent, for example, unauthorised access to
the internal network.
Gateway
A gateway translates one network protocol into another. Routers are also referred to as gateways as they
facilitate access to another network. With DSL, for example, the PPPoE protocol (PPP over Ethernet) is converted to TCP/IP and vice-versa.
Hub
If several computers are to be connected using network cables, then a hub is required. This is a type of
duplicater which copies arriving packets and passes
them unfiltered on to other ports. As a rule, a hub has
between four and eight ports, and is alone sufficient
for small groups of computers. Larger networks require
a more intelligent way of communicating with one another, as data collisions within the network are likely to
occur. In such cases, switches are used.
ICMP (Internet Control Message Protocol)
With the ICMP protocol, error and information messages are exchanged between computers within the
network.
IP address
An IP address consists normally of four numbers having values between 0 and 255 and which are separated
by dots. This address is the unique identification number of a specific device. Every piece of equipment
within a network has an IP address as it is the only
way it can be found by other computers or servers try-

ing to send it information. This can be compared to the
function of a postcode in locating a building on a
street. IP addresses can be allocated either manually
or automatically by a DHCP sever.
ISP (Internet Service Provider)
The Internet Service Provider provides the connection
to the Internet. The customer / user dials in to the
provider using the telephone number (used for analogue and ISDN connections), user name and password.
Kilobit
Data throughput is often given in kilobit. A kilobit is
equivalent to 1,024.bits or 128 bytes.
LAN (Local Area Network)
The local area network is an internal network having
its own IP addresses. A small group of computers is
usually referred to as a local area network. The Internet on the other hand is a world-wide network and as
such is referred to as WAN (Wide Area Network).
MAC Address
MAC stands for Media Access Control. It is the linchpin
of the communication within a network. A MAC address
is hard coded into each network adapter. MAC addresses are worldwide unique and distinctive. Through
MAC addresses, devices within the network can be selected in a reliable way in order to grant or deny them
specific rights on an IP packet level. MAC addresses
are often written on the devices in hexadecimal format.

Modulation
In the ADSL settings, the modulation defines the way
signals are decoded/encoded onto a carrier wave.
NAT (Network Address Translation)
Network Address Translation is a commonly used IP
translation and mapping technology designed for conserving registered IP addresses in large networks and
simplifying IP addressing management tasks.
As its name implies NAT acts as an interpreter between
two networks, which translates IP addresses within private “internal” networks to “legal” IP addresses for
transport over public "external" networks (such as the
Internet). Incoming traffic is translated back for delivery within the inside network.
NAT therefore allows a company or home network with
unregistered “private” addresses to connect to the
Internet by translating those addresses into globally
registered IP addresses. As such it allows an entire
network to share a single internet connection over a
single IP address.
NAT also increases network privacy by hiding internal
IP addresses from external networks.
PPP
Alongside TCP/IP, the point-to-point protocol (PPP) is
one of the most popular protocols existing today. PPP
is used to establish a connection between two remote
sites. Most Internet providers establish a connection to
the customer using the PPP protocol.
PPPoE
A special form of the PPP protocol. “Point-to-Point over
Ethernet” establishes a connection between two remote sites over an Ethernet network.

POTS (Plain Old Telephone Service)
POTS refers to traditional, analogue telephony und
telephone services.
Protocol
A protocol for data transfer communication determines
the way in which data is to be built-up and exchanged.
TCP/IP is a very widespread protocol. If a system does
not understand a protocol, then certain services within
the network may not be accessible.
Radio channel
The use of the radio channels is specified in each country by the relevant authority. A wireless product must
support the relevant channels in order to be used in
that particular country. Its sale within that country
must also be agreed by the corresponding authorities.
In the chapter “Safety and Maintenance” is a list with
all known exceptions.
RJ45
This is the terminology for the outlet and plug type
used for twisted pair network cables.
Server
A server is used to provide a wide variety of services
within a network. For example, a server can be used to
store files or as a backup system. Even if you just install
a programme on your computer and make it accessible
for other users, this can be classified as a server.
Splitter
A splitter distributes a DSL line in a telephone and a
data line. A DSL line can consequently be used for traditional telephone calls as well as for data transfer. The

splitter is installed at the user’s end of the DSL line.
This is generally done by the provider of the line.
Static IP address
Some Internet providers and some devices within a
network (e.g. a server or a router) require the allocation of fixed IP addresses. This must be manually entered and remains allocated to that particular computer until it is changed. Most Internet providers operate on a dynamic IP basis. This means that each time
you connect to the Internet you are allocated a new IP
address. If setting a static address, the DHCP services
must be deactivated.
VPI / VCI
Virtual Path/Channel Identifier are used in combination
as an identifier for an ATM connection and enable that
the data packets are transferred correctly via all
switches and routers. Both values are given by the
ADSL Internet provider.
WEP (Wired Equivalent Privacy)
WEP is a data encryption method used in wireless networks and is part of the 802.11 standard. The standard
foresees a 64 (40) bit or 128 (104) bit key. 24 bit of
the 64 and 128 are used as initialising vector. This is
the reason why the encryption is sometimes described
as 40 and 104 bit.
WLAN /Wireless LAN
Wireless LANs are local wireless networks and are defined by the 802.11 standard. Individual networked
users are connected via radio in a wireless network. A
wireless access point establishes such a wireless network and assumes its management.
