Wireless Local Network (WLAN)
In a wireless local network (WLAN), PCs are linked without wires. The PCs have to be
equipped with a wireless network adapter (WLAN adapter) for this purpose, such as a
Gigaset PC Card or a USB Adapter.
We generally differentiate between two types of wireless network.
u Infrastructure mode
u Ad-hoc mode
Infrastructure mode
Infrastructure mode connects wireless and wired networks with one another. In addition to the mobile stations, infrastructure mode needs an access point such as the
Gigaset SX541 WLAN dsl. The stations in the network always communicate via this
access point in infrastructure mode. Each station that wants to be part of the wireless
network must first register with the access point before it can exchange data.
The access point establishes the connection between the mobile stations of a wireless
network and a wired LAN (Ethernet) or the Internet. In this case, this is described as the
device's router functionality. The router sends data packets that are not addressed to stations within the network "outside" and forwards data packets originating from "outside"
to the appropriate station within the network.
You can use the Gigaset SX541 WLAN dsl to connect
u wirelessly networked PCs to the Internet and
u wirelessly networked PCs to an Ethernet network.
Infrastructure mode is the default configuration of the Gigaset SX541 WLAN dsl. This
configuration is described in the quick guide enclosed with the router.
Ad-hoc mode
An ad-hoc network is a wireless network set up without an access point or router. The
mobile network components that communicate with each other directly and without
wire connections form the network "ad-hoc", i.e. as and when required. All the stations
in the network have the same rights. Ad-hoc networks are used wherever communications networks have to be set up quickly and without any existing network infrastructure
and where the participants are on the move.

Linking wireless networks with the Internet
The Gigaset SX541 WLAN dsl has an ADSL interface that permits all stations within its
local network to access the Internet simultaneously. To be able to use this functionality,
you need a DSL or cable connection obtainable from an Internet provider. Find out
whether your Internet Service Provider supports parallel access by several PCs.

Checking the Connection to the Gigaset SX541 WLAN dsl
Once the network has been set up on your PC, you can check whether the PC is correctly
connected to the Gigaset SX541 WLAN dsl. This can be done as follows:
ì Open Command prompt. To do this, click Start – Programs – Command prompt.
ì Enter the command ping 192.168.2.1.
Please remember:
192.168.2.1 is the default IP address for the Gigaset SX541 WLAN dsl.
If the IP address was changed, enter the new IP address.
The ping command sends data packets to the Gigaset SX541 WLAN dsl with the specified IP address and checks whether the router responds. If this is the case, the command
presents statistics about the connection, for example how many data packets were sent,
how many were received, how long the transfer took, etc. If you can see this information, then the connection to the router is functioning properly.
If the command does not return any statistics, but ends with a time-out, this means that
the components cannot communicate with each other. Check the following points:
1. Is the Ethernet cable between the Gigaset SX541 WLAN dsl and the PC correctly connected or is there a wireless connection via a wireless network adapter?
The LED display for the LAN connections on the Gigaset SX541 WLAN dsl and link
display for the network card in your PC must be illuminated. For wireless connections, the Gigaset WLAN Adapter Monitor must display connection information.
2. Has TCP/IP been properly configured on your PC?
If the Gigaset SX541 WLAN dsl has the IP address 192.168.2.1, your PC's IP address
must be between 192.168.2.2 and 192.168.2.255. The default gateway must have
the address 192.168.2.1.
If you can successfully address the Gigaset SX541 WLAN dsl with the ping command,
then the PC has been configured correctly.

SSID
Before the wireless network components can communicate with each other, you must
use the same SSID (Service Set Identifier).
The default SSID for the Gigaset SX541 WLAN dsl is ConnectionPoint. For security reasons you should change this SSID and deactivate SSID broadcast.
If this option is enabled, the Gigaset SX541 WLAN dsl will send the SSID in all data transmissions and your Gigaset SX541 WLAN dsl's SSID will be displayed on PCs that have a
wireless network adapter. In this case, unauthorised persons could use the SSID to gain
access to your network.
ì Enter a character string of your choice in the SSID field. The SSID is case sensitive. It
can be up to 32 alphanumerical characters long.
Please remember:
The connection to the wireless network adapters will be interrupted until the new
SSID has been entered in them as well.
ì Deactivate the option SSID broadcast and make a note of the SSID. You will need
this to log on your PC.

Setting Security Functions for the Wireless Network
In the next step you can set the encryption and authentication methods for your wireless network.
Wireless networks are even more strongly exposed to the risk of eavesdropping than
wired networks. With conventional network adapters an intruder only needs a device
with a WLAN adapter (for example a Notebook or a PDA (Personal Digital Assistant))
with an appropriately configured network card in order to eavesdrop on every communication made via a nearby wireless LAN.
The Gigaset SX541 WLAN dsl makes use of effective encryption methods to prevent
unauthorised eavesdropping as far as possible.
You can use the following security mechanisms:
u WPA2-PSK or WPA2-PSK / WPA-PSK (see page 63)
u WEP encryption (Wired Equivalent Privacy, see page 64)
We recommend using WPA2-PSK if it is supported by all components in your wireless
network.
You will find further options for setting data encryption and authentication in the
Advanced Settings menu (see page 97).

Schablone 2005_05_02
WPA2 / WPA with Pre-Shared Key (PSK)
WPA is a more advanced procedure than WEP for protecting wireless networks. Dynamic
keys based on TKIP (Temporal Key Integration Protocol) offer increased security. The
new standard WPA2 uses AES for the encryption.
WPA-PSK is a special WPA mode for users at home and in small companies without a
company authentication server. Encryption keys are automatically generated with the
Pre-shared Key, automatically changed ( "rekeying") and authenticated between the
devices after a certain period of time (Rekey Interval).
Please remember:
Every PC (network adapter) that requires access to a wireless network protected by
WPA must also support WPA. To find out whether and how you can use WPA on your
PC, read your network adapter's operating instructions.
ì Select the WPA2-PSK option if it is supported by all components in your wireless network.
or
ì Select the WPA2-PSK / WPA-PSK option if some or all components in your wireless
network support WPA with the TKIP protocol.
ì Enter a key of your choice in the Pre-shared key field (min. 8 to max. 63 characters)
and confirm it by repeating the entry.
You must also set the same Pre-shared Key for all wirelessly connected PCs.
ì To go to the next step, click Next >.

WEP Encryption
WEP (Wired Equivalent Privacy) is an encryption procedure for radio signals in wireless
networks and meets the IEEE 802.11 standard.
If you transmit data wirelessly and not all components in your wireless network support
the higher security standard WPA (see page 63), we recommend that you activate WEPEncryption for these network components.
You can choose either the standard 64-bit key or the more robust 128-bit key for encryption. The keys are generated in hexadecimal or in ASCII format. You must use the same
keys for encryption and decryption for the Gigaset SX541 WLAN dsl and all your wireless
network adapters.
ì Select the Key length: 64 bits or 128 bits.
ì Select the Input type, i.e. whether you wish to enter the key manually or have it
generated automatically by means of a Passphrase.

Manual key entry
ì Select the Key type, Hex or ASCII.
.
If you select Hex, you can use the characters 0 to 9 and A to F.
– With a 64-bit encryption depth, the key is exactly 10 characters long.
– With a 128-bit encryption depth, the key is exactly 26 characters long.
If you select ASCII you can use the characters 0 to 9, A to Z and a to z plus the special
characters in the ASCII character set.
– With a 64-bit encryption depth, the key is exactly 5 characters long.
– With a 128-bit encryption depth, the key is exactly 13 characters long.
ì Confirm the key by entering it again in the Confirm key field.
Generating the key by means of a Passphrase
ì Enter a Passphrase (up to 32 characters) and confirm it by entering it again. The key
is generated automatically.
Please remember:
u It is very important that you make a note of the key or passphrase. You will need
this information to configure the wireless network adapters properly.
u When you have concluded the Security Setup Wizard, you must change the WEP
encryption on the wireless network adapters for the connected PCs in the same
way as they will not otherwise be given access to the Gigaset SX541 WLAN dsl's
wireless network.

ì Click OK to apply the settings.
Attack Detection
If the firewall functions of your Gigaset SX541 WLAN dsl are activated, the device monitors and limits the access of incoming traffic via the DSL connection with a function
called Stateful Packet Inspection (SPI). This allows the Gigaset SX541 WLAN dsl to identify and prevent certain types of attack from the Internet, such as Denial-of-Service
(DoS). DoS attacks are aimed at devices and networks with Internet connections. The
aim is not so much to steal data but to paralyse the computer or network to such an
extent that the network resources are no longer available. A typical hacker attack
involves making a remote computer announce that it is acting for the paralysed device,
for example, and receive the data meant for it.

u Stateful Packet Inspection
Your device monitors and limits the access of incoming traffic from the Internet with
SPI (Stateful Packet Inspection). This allows it to identify and block certain types of
attack such as Denial-of-Service (DoS). A typical DoS attack involves a remote computer paralysing a system and announcing that it is acting for the paralysed device
in order to receive the data meant for it. For the level Custom you can specify yourself whether you wish to activate SPI on your device and which exceptions you wish
to make.
ì Activate or deactivate Stateful Packet Inspection for your device's Internet connection.

Setting up the NAT Function
Your Gigaset SX541 WLAN dsl comes provided with the NAT (Network Address Translation) function. With Address Mapping, several users in your local network can access the
Internet via one or more public IP addresses. In the default setting, all the local IP
address are mapped to your router's public IP address.
One of the characteristics of NAT is that data from the Internet is not allowed into your
local network unless it has been explicitly requested by one of the PCs in that network.
Most Internet applications run behind the NAT firewall without any problems. If you
request Internet pages, for example, or send and receive e-mails, the request for data
from the Internet comes from a PC in the local network and so the router allows the data
through. The router opens exactly one port for the application. A port is an internal PC
address through which the data is exchanged between a server on the Internet and a
client on a PC in the local network. Communicating via a port follows the rules of a particular protocol (TCP or UDP).
If an external application tries to send a call to a PC within the local network, the router
will block it. There is no open port via which the data could enter the local network.
Some applications, such as games on the Internet, require several links, i.e. several ports
so that the players can communicate with each other. In addition, these applications
must also be permitted to send requests from other users on the Internet to the user in
the local network. These applications cannot work if Network Address Translation (NAT)
has been activated.
Using port forwarding (the forwarding of requests to particular ports) the router is
forced to forward requests from the Internet for a certain service, fro example a game,
to the appropriate port or ports on the PC on which the game is running.
Port triggering is a specific variant of port forwarding. Unlike port forwarding, in this
case the Gigaset SX541 WLAN dsl forwards data from the set port block to the PC that
has previously sent data to the Internet via a certain port (trigger port). This means that
approval for the data transfer is not tied to one specific PC in your network, rather to the
port numbers of the required Internet service.
Where configuration is concerned, this means:
u You have to define a so-called trigger port for the application and also the protocol
(TCP or UDP) that this port uses. You then assign the public ports that have to be
opened for the application to this trigger port.
u The router checks all outgoing data for the port number and protocol. If it recognises
a match of port and protocol to a defined trigger port, it will open the assigned public ports and note the IP address of the PC that sent the data. If data comes back from
the Internet via one of these public ports, it allows the data through and directs it to
the right PC. A trigger event always comes from a PC within the local network. If a
trigger port is addressed from outside, it is simply ignored by the router.

Please remember:
u An application that is configured for port triggering can only be run by one user in
the local network at a time.
u As long as the public ports are open, they can be used by unauthorised persons to

When the Gigaset SX541 WLAN dsl is supplied, the NAT function (Network Address
Translation) is activated, i.e. all IP addresses of PCs in the local network are converted to
the router's public IP address when accessing the Internet.

If you configure Port Forwarding, the Gigaset SX541 WLAN dsl outwardly assumes the
role of the servers. It receives requests from remote users under its public IP address and
automatically redirects them to local PCs. The private IP addresses of the servers in the
local network remain protected.
Internet services are addressed via defined port numbers. The Gigaset SX541 WLAN dsl
needs a mapping table of the port numbers to redirect the service requests to the server

Example: the Web server has been configured to react to requests on port 8080.
However, the requests from ripostes enter by port 80 (standard value). If you add the
PC to the forwarding table and define port 80 as the public port and port 8080 as an
internal port, all requests from the Internet are diverted to the service with the port
number 80 on the Web server of the PC you have defined with port 8080.

Opening the Firewall for Selected PCs (Exposed Host)
You can set up a client in your local network to be an exposed host. Your device will
them forward all incoming data traffic from the Internet to this client. You can then, for
example, operate your own Web server on one of the clients in your local network and
make it accessible to Internet users.
As the exposed host, your local client is directly visible to the Internet and therefore particularly exposed to risk (for example from hacker attacks). You should only activate this
function if it is absolutely necessary (for example to operate a Web server) and other
functions (for example port forwarding) are not adequate. In this case you should take
appropriate measures on the clients concerned.

Dynamic DNS
Any service you provide on the Internet can be accessed by a Domain names. Your
router's Public IP address is assigned to this domain name. If your Internet Service Provider for your local network's WAN connection assigns the IP address dynamically, the IP
address of the router can change. The assignment to the domain name will no longer
be valid and your service will no longer be available.
In this case, you must ensure that the assignment of the IP address to the domain name
is updated regularly. This is handled by the dynamic DNS service (DynDNS). You can use
the DynDNS service to assign your Gigaset SX541 WLAN dsl an individual static domain
name on the Internet even if it does not have a static IP address.
There are various providers on the Internet offering a free DynDNS service.
The Gigaset SX541 WLAN dsl uses the DynDNS service from DynDNS.org
(http://www.DynDNS.org). If you use the service of this DynDNS provider, your service
can be reached on the Internet as a subdomain of one of the DynDNS.org domains.

QoS (Quality of Service)
Many communication and multimedia applications require high speed and large bandwidths to transfer data between the local network and the Internet. However, for many
applications there is often only one Internet connection available with limited capacity.
QoS (Quality of Service) divides this capacity between the different applications and
provides undelayed, continuous data transfer where data packets with higher priority
are given transmission preference.
ì In the Advanced Settings – Internet menu, select the entry QoS.
ì Select Differentiated services, i.e. the priorisation of certain services for data transfer between your network and the Internet.
You can determine via Priority which data packets are to be given preferential transmission. With the aid of PHB (Per Hop Behaviours) a decision is also made about whether
data packets are to be forwarded immediately before all others (EF, Expedited Forwarding), guaranteed and without data loss (AF, Assured Forwarding) or normally (BE, Best
Effort). If your application already supports QoS, your application will determine the priority automatically and this will be noted by your device for forwarding. In addition, your
device recognises certain Predefined applications and gives each data packet the relevant priority. You can also determine which proportion of the bandwidth for your Internet connection is to be made available for a certain class as Allocated bandwidth.
ì Select the Allocated bandwidth for the Predefined applications and for the line
(all other applications).
ì Click OK to save and apply the changes.

WPA with Pre-shared Key (WPA-PSK)
WPA-PSK is a special WPA mode that provides encryption protection for users at home
and in small companies without a company authentication server. Encryption keys
are automatically generated with the Pre-shared Key and automatically changed (rekeying) and authenticated between the devices after a certain period of time (Rekey Interval).
Which standard of encryption you can choose depends on the components in your wireless network. Every PC (network adapter) that requires access to a wireless network protected by WPA must also support WPA. To find out whether and how you can use WPA
on your PC, read your network adapter's operating instructions. If all components support WPA2, select option WPA2-PSK. If you are using network adapters that only support WPA, select the option WPA2-PSK / WPA-PSK. The entries described below are the

Setting up Internet telephony (VoIP)
Your Gigaset SX541 WLAN dsl enables you to make telephone calls via the Internet using
an analogue phone connected to the Gigaset SX541 WLAN dsl. To do this, you require
access authorisation from your service provider and the relevant access data. You must
enter this data and other configuration settings for making calls in the VoIP (Voice over
IP) menu in the Advanced Setup.
The menu comprises the following entries:
u VoIP settings: Enter the basic data from your service provider here (see page 105).
u Extensions: Set functions here for two extensions(see page 107).
u Dialing rules: Specify numbers here that are to be called only via the fixed network
or only via the Internet. You can block numbers completely (for example 0190 numbers) or enter a call-by-call provider for the fixed network (see page 108).
Please remember:
If you do not specify any of your own dialing rules, then the default settings will
be used as entered on the Dialing Plans screen in the VoIP menu. All other calls
are made via the Internet. If you press the * key twice before dialing the number
on the phone, then the call will always be made via the fixed network. The dialing
rules will not apply in this case.
Switching over takes a little time. For automatic dialing, insert a pause after the **
by pressing the recall key. You should therefore press: * key, * key, recall key and
then the keys for the required phone number.
u Quick dial: Specify quick dial numbers or terms here for phone numbers you use fre-
quently (see page 110).
Important information:
u If VoIP is not set, you will always make calls via the fixed network and the dialing
rules (see page 108) will not apply.
u All calls from the fixed network are forwarded to the phone connected to the Phone
1 socket.
u If VoIP is set, then – depending on your provider – a call-by-call number is preset for
fixed network calls.
u Please check these dialing rules (see page 108) and amend them if you have agreed
special phone tariffs with another provider.

Security
On the Security screen in the Status menu you will see information about possible
security risks for your device and your network.
u System password not changed
Your device's configuration program is not effectively protected against unauthorised access, as you have either not changed the password since setting the device
up or you have not assigned any password at all. The section entitled "System Password" on page 120 describes how to avoid this security risk.
u Identification of your wireless network visible or not changed
Unauthorised users can also find your wireless network easily as you have not
changed the ID for your wireless network (SSID) since setup and have not deactivated the broadcasting of the SSID (SSID broadcast). The section entitled "Configuring Wireless Connections" on page 95 describes how to avoid this security risk.
u Encryption for your wireless network not activated
None of the data in your wireless network is encrypted when transmitted and can
therefore easily be intercepted. Unauthorised users can also easily access your network, your PCs and your Internet connection by this means. The section entitled
"Setting Wireless Security" on page 97 describes how to avoid this security risk.
u Access to your wireless network not restricted to allowed clients
Users can access your wireless network from any PC. The section entitled "Allowed

Installing the Printer Port for Network Printers
Schablone 2005_05_02
Installing the Printer Port for Network Printers
Your Gigaset SX541 WLAN dsl is equipped with a USB port that you can use, for example, to connect a printer for use as the network printer.
Introduction
A network printer is a printer on which you can print your documents without it being
connected to your PC, for example to LPT1, the parallel interface. This has the advantage
that you only need this printer once in your network. All PCs for which it is released can
access it and work with it.
In most cases, a printer of this type is connected to another PC in the network. This does
indeed offer the advantage referred to above, but it has serious disadvantages:
u The printer can only be used by others if the PC to which it is connected is switched
on.
u The print job you send to the PC on which the printer depends reduces the perform-
ance (resources) of this PC.
If you use the USB port on the Gigaset SX541 WLAN dsl for your printer, you have all the
advantages of a network printer without the disadvantages referred to above:
u The network, and consequently also the printer, is always ready (the Gigaset SX541
WLAN dsl and the printer itself must be switched on, of course).
u As it is connected to the USB printer port on your Gigaset SX541 WLAN dsl, it does
not detract from the performance of any other PC in the network.
To facilitate this option, you must first set up a printer port on each PC wanting to use
the network printer. A printer port is an interface on the PCs that forwards the print job
to an IP address within the network.
Once you have set up this port, you must install the printer driver.
Note:
For multifunction devices (combination of printer, copier or fax) only the printer functionality is supported.
The printer server can only be used at present with selected printers that support USB
V2.0. You can obtain further information by contacting the hotline or else on the
Internet (see Quick Start Guide).

Instructions for Setting up a Printer on the PC
Once you have installed the printer port you still cannot start printing. The printer port
is nothing more than an additional interface on your PC, comparable with the USB port.
It means that any printer you install on this port is also regarded as a local printer even
though it is located in the network and possibly remote from you.
You still need to connect and configure the printer to this port.
ì Connect the printer to the USB interface on your Gigaset SX541 WLAN dsl.
The printer is installed in the same way as any other printer:
ì Go to Start – Settings – Printers and click Add Printer.
ì In the window that opens, click Next.
ì Proceed as instructed by the printer installation wizard. Please note:
In the window in which you are prompted to specify the location of the printer, you
should select Local printer (usually the default setting).
ì Then click Next.
ì Continue to install the printer. Select your printer and click Next.
ì When the window appears in which you are prompted to enter the type of connection, double click the port name Gigaset_printerport.
ì Then continue to install the printer and finish the installation.
Note:
The Gigaset SX541 WLAN dsl's printer server does not work bidirectionally. It does not

Symptom
You cannot connect to the
Internet.
Possible cause and solutions
ì Check whether the Connect on demand option is
deactivated. In this case, connections cannot be
opened automatically.
ì Select Connect on demand. Remember that this
setting may lead to higher costs if you are billed on
the time used.
ì The connection may have been terminated manu-
ally with the Connect on demand option selected.
– Open the connection manually using the
Connect button again or
– restart the Gigaset SX541 WLAN dsl.
In both cases, the Connect on demand setting will
be active again.
ì Check whether you have exceeded the Time and

Volume Contingent for your Internet use.
The wireless network adapter is not using the correct
SSID.
ì Change the SSID on the network adapter.
Either encryption is enabled on the Gigaset SX541
WLAN dsl but not on the wireless network adapter, or it
is not using the correct key or is using another type of
encryption.
ì Activate the same encryption on the network
adapter with the correct key.
If you do not know the key, you will have to reset
the Gigaset SX541 WLAN dsl (see page 18).
Warning: Please bear in mind that this will restore
all the configuration settings to the factory settings.

Symptom
The Gigaset SX541 WLAN
dsl or other PCs cannot be
reached by a PC in the connected LAN with a ping
command.
No connection to the
Gigaset SX541 WLAN dsl's
configuration environment.
Possible cause and solutions
ì Make sure that TCP/IP has been installed and configured on all the PCs in the local network.
ì Check that the IP addresses have been properly
configured. In most cases you can use the
Gigaset SX541 WLAN dsl's DHCP function to assign
dynamic addresses to the PCs in the LAN. In this
case, you have to configure the TCP/IP settings of all
the PCs so that they obtain the IP address automatically.
ì
If you configure the IP addresses in the LAN
manually, remember to use the subnet mask
255.255.255.x. This means that the first three
parts of the IP address on each PC and the
Gigaset SX541 WLAN dsl have to be identical. The
device also has to be configured as a DNS server.
Use the ping command to check whether you can
establish a network connection to the Gigaset
SX541 WLAN dsl.
ì Check the network cable between the PC you
want to use to administer the device and the
Gigaset SX541 WLAN dsl.
ì If the PC you want to use is in the device's local
network, make sure that you are using the correct
IP address administration (see above).
ì If the PC you want to use is not in the router's local
network, it must be authorised via remote management.
Reset the Gigaset SX541 WLAN dsl
(see page 19).
Password forgotten or lost
ì
You cannot access a
resource (drive or printer)
on a different PC.
Warning: Please bear in mind that this will restore all
the configuration settings to the factory settings.
ì Make sure that TCP/IP has been installed and configured on all the PCs in the local network and that
the PCs all belong to the same workgroup.
ì Check whether the resource has been released on
the PC in question and whether you have the necessary access rights.
ì Printing: Check whether the printer has been set up
as a network printer.

GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your freedom to share and change it. By
contrast, the GNU General Public License is intended to guarantee your freedom to share and
change free software--to make sure the software is free for all its users. This General Public License
applies to most of the Free Software Foundation’s software and to any other program whose
authors commit to using it. (Some other Free Software Foundation software is covered by the GNU
Library General Public License instead.) You can apply it to your programs, too.
When we speak of free software, we are referring to freedom, not price. Our General Public
Licenses are designed to make sure that you have the freedom to distribute copies of free software
(and charge for this service if you wish), that you receive source code or can get it if you want it,
that you can change the software or use pieces of it in new free programs; and that you know you
can do these things.
To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or
to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if
you distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether gratis or for a fee, you must give
the recipients all the rights that you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their rights.
We protect your rights with two steps: (1) copyright the software, and (2) offer you this license
which gives you legal permission to copy, distribute and/or modify the software.
Also, for each author’s protection and ours, we want to make certain that everyone understands
that there is no warranty for this free software. If the software is modified by someone else and
passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors’ reputations.
Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making
the program proprietary. To prevent this, we have made it clear that any patent must be licensed
for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and modification follow.

GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The
"Program", below, refers to any such program or work, and a "work based on the Program" means
either the Program or any derivative work under copyright law: that is to say, a work containing the
Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each
licensee is addressed as "you".
Activities other than copying, distribution and modification are not covered by this License; they
are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having
been made by running the Program). Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program’s source code as you receive it, in
any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this
License and to the absence of any warranty; and give any other recipients of the Program a copy
of this License along with the Program.
You may charge a fee for the physical act of transferring a copy, and you may at your option offer
warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion of it, thus forming a work
based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices stating that you changed the files
and the date of any change.
b) You must cause any work that you distribute or publish, that in whole or in part contains or is
derived from the Program or any part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively when run, you must cause it,
when started running for such interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a notice that there is no warranty (or
else, saying that you provide a warranty) and that users may redistribute the program under these
conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself
is interactive but does not normally print such an announcement, your work based on the Program
is not required to print an announcement.)
These requirements apply to the modified work as a whole. If identifiable sections of that work are
not derived from the Program, and can be reasonably considered independent and separate works
in themselves, then this License, and its terms, do not apply to those sections when you distribute
them as separate works. But when you distribute the same sections as part of a whole which is a
work based on the Program, the distribution of the whole must be on the terms of this License,
whose permissions for other licensees extend to the entire whole, and thus to each and every part
regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely
by you; rather, the intent is to exercise the right to control the distribution of derivative or collective
works based on the Program.
In addition, mere aggregation of another work not based on the Program with the Program (or with
a work based on the Program) on a volume of a storage or distribution medium does not bring the
other work under the scope of this License.
3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code
or executable form under the terms of Sections 1 and 2 above provided that you also do one of the
following:
156
Gigaset SX541 WLAN dsl / englisch / A31008-M1025-L101-1-7619

Appendix
a) Accompany it with the complete corresponding machine-readable source code, which must be
distributed under the terms of Sections 1 and 2 above on a medium customarily used for software
interchange; or,
b) Accompany it with a written offer, valid for at least three years, to give any third party, for a
charge no more than your cost of physically performing source distribution, a complete machinereadable copy of the corresponding source code, to be distributed under the terms of Sections 1
and 2 above on a medium customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer to distribute corresponding
source code. (This alternative is allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for making modifications to it.
For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and
installation of the executable. However, as a special exception, the source code distributed need
not include anything that is normally distributed (in either source or binary form) with the major
components (compiler, kernel, and so on) of the operating system on which the executable runs,
unless that component itself accompanies the executable.
If distribution of executable or object code is made by offering access to copy from a designated
place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along
with the object code.
4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided
under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License. However, parties who have
received copies, or rights, from you under this License will not have their licenses terminated so
long as such parties remain in full compliance.
5. You are not required to accept this License, since you have not signed it. However, nothing else
grants you permission to modify or distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so,
and all its terms and conditions for copying, distributing or modifying the Program or works based
on it.
6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients'
exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License.
7. If, as a consequence of a court judgment or allegation of patent infringement or for any other
reason (not limited to patent issues), conditions are imposed on you (whether by court order,
agreement or otherwise) that contradict the conditions of this License, they do not excuse you
from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your
obligations under this License and any other pertinent obligations, then as a consequence you may
not distribute the Program at all. For example, if a patent license would not permit royalty-free
redistribution of the Program by all those who receive copies directly or indirectly through you,
then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under any particular circumstance, the
balance of the section is intended to apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any patents or other property right
claims or to contest validity of any such claims; this section has the sole purpose of protecting the

integrity of the free software distribution system, which is implemented by public license practices.
Many people have made generous contributions to the wide range of software distributed through
that system in reliance on consistent application of that system; it is up to the author/donor to
decide if he or she is willing to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to be a consequence of the rest
of this License.
8. If the distribution and/or use of the Program is restricted in certain countries either by patents
or by copyrighted interfaces, the original copyright holder who places the Program under this
License may add an explicit geographical distribution limitation excluding those countries, so that
distribution is permitted only in or among countries not thus excluded. In such case, this License
incorporates the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions of the General Public
License from time to time. Such new versions will be similar in spirit to the present version, but may
differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Program specifies a version number
of this License which applies to it and "any later version", you have the option of following the
terms and conditions either of that version or of any later version published by the Free Software
Foundation. If the Program does not specify a version number of this License, you may choose any
version ever published by the Free Software Foundation.
10. If you wish to incorporate parts of the Program into other free programs whose distribution
conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals of preserving the free status
of all derivatives of our free software and of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN
WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE
ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM
AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR
LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH
ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest possible use to the public, the
best way to achieve this is to make it free software which everyone can redistribute and change
under these terms.
To do so, attach the following notices to the program. It is safest to attach them to the start of each
source file to most effectively convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software; you can redistribute it and/or modify it under the terms of the
GNU General Public License as published by the Free Software Foundation; either version 2 of
the License, or (at your option) any later version.
This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY;
without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details.
You should have received a copy of the GNU General Public License along with this program;
if not, write to the Free Software Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA
02111-1307 USA
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this when it starts in an interactive
mode:
Gnomovision version 69, Copyright (C) year name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type ’show w’.
This is free software, and you are welcome to redistribute it under certain conditions; type
’show c’ for details.
The hypothetical commands ’show w’ and ’show c’ should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than ’show w’
and ’show c’; they could even be mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your school, if any, to sign a
"copyright disclaimer" for the program, if necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program ’Gnomovision’ (which
makes passes at compilers) written by James Hacker.

This General Public License does not permit incorporating your program into proprietary programs.
If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Library General Public

Version 2.1, February 1999
Copyright (C) 1991, 1999 Free Software Foundation, Inc.
59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
[This is the first released version of the Lesser GPL. It also counts as the successor of the GNU
Library Public License, version 2, hence the version number 2.1.]
Preamble
The licenses for most software are designed to take away your freedom to share and change it. By
contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and
change free software--to make sure the software is free for all its users.
This license, the Lesser General Public License, applies to some specially designated software packages--typically libraries--of the Free Software Foundation and other authors who decide to use it.
You can use it too, but we suggest you first think carefully about whether this license or the ordinary General Public License is the better strategy to use in any particular case, based on the explanations below.
When we speak of free software, we are referring to freedom of use, not price. Our General Public
Licenses are designed to make sure that you have the freedom to distribute copies of free software
(and charge for this service if you wish); that you receive source code or can get it if you want it;
that you can change the software and use pieces of it in new free programs; and that you are
informed that you can do these things.
To protect your rights, we need to make restrictions that forbid distributors to deny you these rights
or to ask you to surrender these rights. These restrictions translate to certain responsibilities for you
if you distribute copies of the library or if you modify it.
For example, if you distribute copies of the library, whether gratis or for a fee, you must give the
recipients all the rights that we gave you. You must make sure that they, too, receive or can get the
source code. If you link other code with the library, you must provide complete object files to the
recipients, so that they can relink them with the library after making changes to the library and recompiling it. And you must show them these terms so they know their rights.
We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you
this license, which gives you legal permission to copy, distribute and/or modify the library.
To protect each distributor, we want to make it very clear that there is no warranty for the free
library. Also, if the library is modified by someone else and passed on, the recipients should know
that what they have is not the original version, so that the original author’s reputation will not be
affected by problems that might be introduced by others.
Finally, software patents pose a constant threat to the existence of any free program. We wish to
make sure that a company cannot effectively restrict the users of a free program by obtaining a
restrictive license from a patent holder. Therefore, we insist that any patent license obtained for a
version of the library must be consistent with the full freedom of use specified in this license.
Most GNU software, including some libraries, is covered by the ordinary GNU General Public
License. This license, the GNU Lesser General Public License, applies to certain designated libraries,
and is quite different from the ordinary General Public License. We use this license for certain libraries in order to permit linking those libraries into non-free programs.
When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library. The ordinary
General Public License therefore permits such linking only if the entire combination fits its criteria

of freedom. The Lesser General Public License permits more lax criteria for linking other code with
the library.
We call this license the "Lesser" General Public License because it does Less to protect the user’s
freedom than the ordinary General Public License. It also provides other free software developers
Less of an advantage over competing non-free programs. These disadvantages are the reason we
use the ordinary General Public License for many libraries. However, the Lesser license provides
advantages in certain special circumstances.
For example, on rare occasions, there may be a special need to encourage the widest possible use
of a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must
be allowed to use the library. A more frequent case is that a free library does the same job as widely
used non-free libraries. In this case, there is little to gain by limiting the free library to free software
only, so we use the Lesser General Public License.
In other cases, permission to use a particular library in non-free programs enables a greater
number of people to use a large body of free software. For example, permission to use the GNU C
Library in non-free programs enables many more people to use the whole GNU operating system,
as well as its variant, the GNU/Linux operating system.
Although the Lesser General Public License is Less protective of the users’ freedom, it does ensure
that the user of a program that is linked with the Library has the freedom and the wherewithal to
run that program using a modified version of the Library.
The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The
former contains code derived from the library, whereas the latter must be combined with the
library in order to run.
GNU LESSER GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License Agreement applies to any software library or other program which contains a notice
placed by the copyright holder or other authorized party saying it may be distributed under the
terms of this Lesser General Public License (also called "this License"). Each licensee is addressed
as "you".
A "library" means a collection of software functions and/or data prepared so as to be conveniently
linked with application programs (which use some of those functions and data) to form executables.
The "Library", below, refers to any such software library or work which has been distributed under
these terms. A "work based on the Library" means either the Library or any derivative work under
copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with
modifications and/or translated straightforwardly into another language. (Hereinafter, translation
is included without limitation in the term "modification".)
"Source code" for a work means the preferred form of the work for making modifications to it. For
a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the
library.
Activities other than copying, distribution and modification are not covered by this License; they
are outside its scope. The act of running a program using the Library is not restricted, and output
from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the
Library does and what the program that uses the Library does.
1. You may copy and distribute verbatim copies of the Library's complete source code as you
receive it, in any medium, provided that you conspicuously and appropriately publish on each copy
an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to

this License and to the absence of any warranty; and distribute a copy of this License along with
the Library.
You may charge a fee for the physical act of transferring a copy, and you may at your option offer
warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based
on the Library, and copy and distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) The modified work must itself be a software library.
b) You must cause the files modified to carry prominent notices stating that you changed the files
and the date of any change.
c) You must cause the whole of the work to be licensed at no charge to all third parties under the
terms of this License.
d) If a facility in the modified Library refers to a function or a table of data to be supplied by an
application program that uses the facility, other than as an argument passed when the facility is
invoked, then you must make a good faith effort to ensure that, in the event an application does
not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful.
(For example, a function in a library to compute square roots has a purpose that is entirely welldefined independent of the application. Therefore, Subsection 2d requires that any applicationsupplied function or table used by this function must be optional: if the application does not supply
it, the square root function must still compute square roots.)
These requirements apply to the modified work as a whole. If identifiable sections of that work are
not derived from the Library, and can be reasonably considered independent and separate works
in themselves, then this License, and its terms, do not apply to those sections when you distribute
them as separate works. But when you distribute the same sections as part of a whole which is a
work based on the Library, the distribution of the whole must be on the terms of this License,
whose permissions for other licensees extend to the entire whole, and thus to each and every part
regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely
by you; rather, the intent is to exercise the right to control the distribution of derivative or collective
works based on the Library.
In addition, mere aggregation of another work not based on the Library with the Library (or with a
work based on the Library) on a volume of a storage or distribution medium does not bring the
other work under the scope of this License.
3. You may opt to apply the terms of the ordinary GNU General Public License instead of this
License to a given copy of the Library. To do this, you must alter all the notices that refer to this
License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this
License. (If a newer version than version 2 of the ordinary GNU General Public License has
appeared, then you can specify that version instead if you wish.) Do not make any other change in
these notices.
Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy.
This option is useful when you wish to copy part of the code of the Library into a program that is
not a library.
4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in
object code or executable form under the terms of Sections 1 and 2 above provided that you
accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software
interchange.

Appendix
If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with
the object code.
5. A program that contains no derivative of any portion of the Library, but is designed to work with
the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work,
in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this
License.
However, linking a "work that uses the Library" with the Library creates an executable that is a
derivative of the Library (because it contains portions of the Library), rather than a "work that uses
the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables.
When a "work that uses the Library" uses material from a header file that is part of the Library, the
object code for the work may be a derivative work of the Library even though the source code is
not. Whether this is true is especially significant if the work can be linked without the Library, or if
the work is itself a library. The threshold for this to be true is not precisely defined by law.
If such an object file uses only numerical parameters, data structure layouts and accessors, and
small macros and small inline functions (ten lines or less in length), then the use of the object file
is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this
object code plus portions of the Library will still fall under Section 6.)
Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work
under the terms of Section 6. Any executables containing that work also fall under Section 6,
whether or not they are linked directly with the Library itself.
6. As an exception to the Sections above, you may also combine or link a "work that uses the
Library" with the Library to produce a work containing portions of the Library, and distribute that
work under terms of your choice, provided that the terms permit modification of the work for the
customer's own use and reverse engineering for debugging such modifications.
You must give prominent notice with each copy of the work that the Library is used in it and that
the Library and its use are covered by this License. You must supply a copy of this License. If the
work during execution displays copyright notices, you must include the copyright notice for the
Library among them, as well as a reference directing the user to the copy of this License. Also, you
must do one of these things:
a) Accompany the work with the complete corresponding machine-readable source code for the
Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete
machine-readable "work that uses the Library", as object code and/or source code, so that the user
can modify the Library and then relink to produce a modified executable containing the modified
Library. (It is understood that the user who changes the contents of definitions files in the Library
will not necessarily be able to recompile the application to use the modified definitions.)
b) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is
one that (1) uses at run time a copy of the library already present on the user's computer system,
rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with.
c) Accompany the work with a written offer, valid for at least three years, to give the same user the
materials specified in Subsection 6a, above, for a charge no more than the cost of performing this
distribution.
d) If distribution of the work is made by offering access to copy from a designated place, offer
equivalent access to copy the above specified materials from the same place.
e) Verify that the user has already received a copy of these materials or that you have already sent
this user a copy.

Appendix
For an executable, the required form of the "work that uses the Library" must include any data and
utility programs needed for reproducing the executable from it. However, as a special exception,
the materials to be distributed need not include anything that is normally distributed (in either
source or binary form) with the major components (compiler, kernel, and so on) of the operating
system on which the executable runs, unless that component itself accompanies the executable.
It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot
use both them and the Library together in an executable that you distribute.
7. You may place library facilities that are a work based on the Library side-by-side in a single library
together with other library facilities not covered by this License, and distribute such a combined
library, provided that the separate distribution of the work based on the Library and of the other
library facilities is otherwise permitted, and provided that you do these two things:
a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections
above.
b) Give prominent notice with the combined library of the fact that part of it is a work based on the
Library, and explaining where to find the accompanying uncombined form of the same work.
8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute
the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses
terminated so long as such parties remain in full compliance.
9. You are not required to accept this License, since you have not signed it. However, nothing else
grants you permission to modify or distribute the Library or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by modifying or distributing the
Library (or any work based on the Library), you indicate your acceptance of this License to do so,
and all its terms and conditions for copying, distributing or modifying the Library or works based
on it.
10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the
Library subject to these terms and conditions. You may not impose any further restrictions on the
recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance
by third parties with this License.
11. If, as a consequence of a court judgment or allegation of patent infringement or for any other
reason (not limited to patent issues), conditions are imposed on you (whether by court order,
agreement or otherwise) that contradict the conditions of this License, they do not excuse you
from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your
obligations under this License and any other pertinent obligations, then as a consequence you may
not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the
only way you could satisfy both it and this License would be to refrain entirely from distribution of
the Library.
If any portion of this section is held invalid or unenforceable under any particular circumstance, the
balance of the section is intended to apply, and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any patents or other property right
claims or to contest validity of any such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system which is implemented by public license practices.
Many people have made generous contributions to the wide range of software distributed through
that system in reliance on consistent application of that system; it is up to the author/donor to
decide if he or she is willing to distribute software through any other system and a licensee cannot
impose that choice.

Appendix
This section is intended to make thoroughly clear what is believed to be a consequence of the rest
of this License.
12. If the distribution and/or use of the Library is restricted in certain countries either by patents or
by copyrighted interfaces, the original copyright holder who places the Library under this License
may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License.
13. The Free Software Foundation may publish revised and/or new versions of the Lesser General
Public License from time to time. Such new versions will be similar in spirit to the present version,
but may differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Library specifies a version number of
this License which applies to it and "any later version", you have the option of following the terms
and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever
published by the Free Software Foundation.
14. If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, write to the author to ask for permission. For software which
is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free
status of all derivatives of our free software and of promoting the sharing and reuse of software
generally.
NO WARRANTY
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE
LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN
WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE
ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE
LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
CORRECTION.
16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS
PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE
OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH
ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

How to Apply These Terms to Your New Libraries
If you develop a new library, and you want it to be of the greatest possible use to the public, we
recommend making it free software that everyone can redistribute and change. You can do so by
permitting redistribution under these terms (or, alternatively, under the terms of the ordinary General Public License).
To apply these terms, attach the following notices to the library. It is safest to attach them to the
start of each source file to most effectively convey the exclusion of warranty; and each file should
have at least the "copyright" line and a pointer to where the full notice is found.
<one line to give the library’s name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This library is free software; you can redistribute it and/or modify it under the terms of the GNU
Lesser General Public License as published by the Free Software Foundation; either version 2.1
of the License, or (at your option) any later version.
This library is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
See the GNU Lesser General Public License for more details.
You should have received a copy of the GNU Lesser General Public License along with this
library; if not, write to the Free Software Foundation, Inc., 59 Temple Place, Suite 330, Boston,
MA 02111-1307 USA
Also add information on how to contact you by electronic and paper mail.
You should also get your employer (if you work as a programmer) or your school, if any, to sign a
"copyright disclaimer" for the library, if necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the library ’Frob’ (a library for tweaking knobs) written by James Random Hacker.

Access Point
An Access Point, such as the Gigaset SX541 WLAN dsl, is the centre of a wireless local
network (WLAN). It handles the connection of the wireless linked network components
and regulates the data traffic in the wireless network. The Access Point also serves as an
interface to other networks, for example an existing Ethernet LAN or via a modem to the
Internet. The operating mode of wireless networks with an Access Point is called
Infrastructure mode.
Ad-hoc mode
Ad-hoc mode describes wireless local networks (WLANs) in which the network components set up a spontaneous network without an Access Point for example several Notebooks in a conference. All the network components are peers. They must have a wireless Network adapter.
Auto Connect
Auto Connect means that applications such as Web browser, Messenger and Email
automatically open an Internet connection when they are launched. This can lead to
high charges if you are not using Flat rate. This function can be deactivated at the
Gigaset SX541 WLAN dsl to save call charges.
Bridge
A Bridge connects several network segments to form a joint network, for example to
make a TCP/IP network. The segments can have different physical characteristics, for
example different connections such as Ethernet and wireless LANs. Linking individual
segments via Bridges allows local networks of practically unlimited size.
See also: Switch, Hub, Router, Gateway
Broadcast
A Broadcast is a data packet not directed to a particular recipient but to all the network
components in the network. The Gigaset SX541 WLAN dsl does not pass broadcast packets on; they always remain within the local network (LAN) it administers.
BSSID
Basic Service Set ID
BSSID permits unique differentiation of one wireless network (WLAN) from another. In
Infrastructure mode, the BSSID is the MAC address of the Access Point. In wireless networks in Ad-hoc mode the BSSID is the MAC address of any one of the participants.
Client
A Client is an application that requests a service from a Server. For example, an http Client on a PC in a local network requests data, i.e. Web pages from an HTTP Server on the
Internet. Frequently the network component (for example the PC) on which the Client
application is running is also called a Client.

DHCP
Dynamic Host Configuration Protocol
DHCP handles the automatic assignment of IP addresses to network components. It was
developed because in large networks – especially the Internet – the defining of IP
addresses is very complex as participants frequently move, drop out or new ones join.
A DHCP Server automatically assigns the connected network components (DHCP Clients) Dynamic IP addresses from a defined IP pool range thus saving a great deal of configuration work. In addition, the address blocks can be used more effectively: since not
all participants are on the network at the same time, the same IP address can be
assigned to different network components in succession as and when required.
The Gigaset SX541 WLAN dsl includes a DHCP server and uses it to assign automatic IP
addresses to PCs in the local network. You can specify that the IP addresses for certain
PCs are never changed.
DHCP Server
See DHCP
DMZ
Demilitarised Zone
DMZ describes a part of a network that is outside the Firewall. A DMZ is set up, as it
were, between a network you want to protect (for example a LAN) and an insecure network (for example the Internet). A DMZ is useful if you want to offer Server services on
the Internet which for security reasons are not to be run from behind the firewall or if
Internet applications do not work properly behind a firewall. A DMZ permits unrestricted
access from the Internet to only one or a few network components, while the other network components remain secure behind the firewall.
DNS
Domain Name System
The assignment of DNS permits IP addresses to computers or Domain names that are
easier to remember. A DNS server must administer this information for each LAN with
an Internet connection. As soon as a page on the Internet is called up, the browser
obtains the corresponding IP address from the DNS Server so that it can establish the
connection.
The assignment of domain names to IP addresses on the Internet follows a hierarchical
system. A local PC only knows the address of the local Name Server. This in turn knows
all the addresses of the PCs in the local network and the superordinated Name Servers,
which again know addresses and the next superordinated Name Servers.
DNS server
See DNS
Domain name
The Domain name is the reference to one or more Web servers on the Internet.
The Domain name is mapped via the DNS service to the corresponding IP address.

DoS attack
Denial of Service
A DoS attack is a particular form of hacker attack directed at computers and networks
with a connection to the Internet. The aim is not so much to steal data but to paralyse
the computer or network so severely that the network resources are no longer available.
A typical hacker attack involves making a remote computer announce that it is acting for
the paralysed computer, for example, and receive the data meant for you.
DSL
Digital Subscriber Line
DSL is a data transmission technique in which a connection to the Internet can be run
at 1.5 Mbps over normal telephone lines. A DSL connection is provided by an Internet
Provider. It requires a DSL modem.
Dynamic IP address
A dynamic IP address is assigned to a network component automatically by the DHCP.
This means that the IP address of a network component can change with every login or
at certain intervals.
See also Static IP address
DynDNS
Dynamic DNS
The assignment of Domain names and IP addresses is handled by the Domain Name
Service (DNS). For Dynamic IP addresses this service is now enhanced with so-called
Dynamic DNS (DynDNS). It enables the use of a network component with a dynamic
IP address as a Server on the Internet. DynDNS ensures that a service can always be
addressed on the Internet under the same Domain name regardless of the current
IP address.
Encryption
Encryption protects confidential information against unauthorised access. With an
encryption system, data packets can be sent securely over a network. The Gigaset
SX541 WLAN dsl offers WEP encryption and WPA for secure data transmission over wireless networks.
Ethernet
Ethernet is a network technology for local networks (LANs) defined by the IEEE as standard IEEE 802.3. Ethernet uses a base band cable with a transmission rate of 10 or 100
Mbps.

IGMP
Internet Group Management Protocol
IGMP is an Internet Protocol that enables an Internet computer to inform neighbouring
routers that it is a member of a multicast group. With multicasting, a computer can send
content on the Internet to several other computers that have registered an interest in
the first computer's content. Multicasting can, for example, be used for multimedia programs for media streaming to recipients that have set up multicast group membership.
Infrastructure mode
Infrastructure mode is a way of operating wireless local networks (WLANs) in which an
Access Point handles the data traffic. Network components cannot establish a direct
connection with each other as is the case in Ad-hoc mode.
Internet
The Internet is a wide-area network (WAN) linking several million users around the
world. A number of Protocols have been created for exchanging data, and these are
known collectively as TCP/IP. All participants on the Internet are identifiable by an IP
address. Servers are addressed by a Domain names (for example siemens.com). Domain
names are assigned to IP addresses by the Domain Name Service (DNS).
Among the most important Internet services are:
u electronic mail (email)
u the World Wide Web (WWW)
u file transfer (FTP)
u discussion forums (Usenet / Newsgroups)

Internet Protocol
The IP Protocol is one of the TCP/IP protocols. It is responsible for addressing parties in a
network using IP addresses, and routes data from the sender to the recipient. It decides
the paths along which the data packets travel from the sender to the recipient in a complex network (routing).

IP address
The IP address is the unique network-wide address of a network component in a network based on the TCP/IP protocol (for example in a local network (LAN) or on the Internet). The IP address has four parts (decimal numbers) separated by full stops (for example 192.168.1.1). The IP address comprises the network number and the computer
number. Depending on the Subnet mask, one, two or three parts form the network
number, the remainder forms the computer number. You can find out the IP address of
your PC using the ipconfig command.
IP addresses can be assigned manually (see Static IP address) or automatically
(see Dynamic IP address).
On the Internet, Domain names are normally used instead of the IP addresses. DNS is
used to assign domain names to IP addresses.
The Gigaset SX541 WLAN dsl has a Private IP address and a Public IP address.
IP pool range
The Gigaset SX541 WLAN dsl's IP address pool defines a range of IP addresses that the
router's DHCP Server can use to assign Dynamic IP addresses.

Internet Provider
LAN
Local network
A local network links network components so that they can exchange data and share
resources. The physical range is restricted to a particular area (a site). As a rule, the users
and operators are identical. A local network can be connected to other local networks
or to a wide-area network (WAN) such as the Internet.
With the Gigaset SX541 WLAN dsl, you can set up a wired local Ethernet network and a
wireless IEEE 802.11g standard network (WLAN).
Lease time
The lease time defines the period of time for which the PCs keep the Dynamic IP address
assigned to them by the DHCP server without changing them.
Local IP address
See Private IP address
MAC address
Media Access Control
The MAC address is used for the globally unique identification of a Network adapter. It
comprises six parts (hexadecimal numbers), for example 00-90-96-34-00-1A. The MAC
address is assigned by the network adapter manufacturer and cannot be changed.

Maximum Receive Unit
The MRU defines the maximum user data volume within a data packet.
MTU
Maximum Transmission Unit
The MTU defines the maximum length of a data packet that can carried over the network at a time.
NAT
Network Address Translation
NAT is a method for converting IP addresses (mostly Private IP addresses) within a network into one or several Public IP addresses on the Internet. With NAT, several network
components in a LAN can share the router's public IP address to connect to the Internet.
The network components of the local network are hidden behind the router's IP address
registered on the Internet. Because of this security function, NAT is frequently used as
part of the Firewall of a network. If you want to make services on a PC in the local network available on the Internet despite NAT, you can configure the Gigaset SX541 WLAN
dsl as a Virtual server.
Network
A network is a group of devices connected in wired or wireless mode so that they can
share resources such as data and peripherals. A general distinction is made between
local area networks (LANs) and wide area networks (WANs).
Network adapter
The network adapter is the hardware device that creates the connection between a network component and a local network. The connection can be wired or wireless. An Ethernet network card is an example of a wired network adapter. The Gigaset PC Card and
the Gigaset USB Adapter are examples of wireless network adapters.
A network adapter has a unique address, the MAC address.

Port
Data is exchanged between two applications in a network across a port.The port
number addresses an application within a network component. The combination of IP
address/port number uniquely identifies the recipient or sender of a data packet within
a network. Some applications (for example Internet services such as HTTP or FTP) work
with fixed port numbers, others are allocated a free port number whenever they need
one.
Port Forwarding
In port forwarding the Gigaset SX541 WLAN dsl directs data packets from the Internet
that are addressed to a particular Port to the corresponding port of the appropriate network component. This enables servers within the local area network to offer services on
the Internet without them needing a Public IP address.

PPPoA
Point-to-Point Protocol over ATM
PPPoA is a Protocol for connecting network components in a local Ethernet network to
the Internet via an ATM network.
PPPoE
Point-to-Point Protocol over Ethernet
PPPoE is a Protocol for connecting network components in a local Ethernet network to
the Internet via a modem.
Private IP address
The private IP address (also known as the local IP address) is a network component's
address within the local area network (LAN). The network operator can assign any
address he or she wants. Devices that act as a link from a local network, such as the
Gigaset SX541 WLAN dsl, have a private and a Public IP address.
Protocol
A protocol describes the agreements for communicating in a network. It contains rules
for opening, administering and closing a connection, as well as about data formats,
time frames and handling possible errors. Communications between two applications
require different protocols at various levels, for example the TCP/IP protocols for the
Internet.
Public IP address
The public IP address (also known as the global IP address) is a network component's
address on the Internet. It is assigned by the Internet Provider. Devices that create a link
from a LAN to the Internet, such as the Gigaset SX541 WLAN dsl, have a public and a
Private IP address.

Rekey Interval
The rekey interval is the period after which new keys are automatically generated for
data encryption with WPA-PSK.
Remote Management
Remote Management refers to the ability to manage a network from a network component that is actually outside the local area network (LAN).
Repeater
A repeater extends the range of a wireless local area network by relaying data from the
Access Point to additional PCs or Network adapters.
Roaming
Roaming extends the range of a wireless LAN by using several Access Points that use the
same SSID and the same radio channel and are linked via Ethernet. The PCs in the network can switch dynamically between several Access Points without losing the existing
network connection.
Router
A router directs data packets from one local area network (LAN) to another via the fastest route. A router makes it possible to connect networks that have different network
technologies. For example, it can link a local network with Ethernet or WLAN technology to the Internet.

Server
A server makes a service available to other network components (Clients). The term
"server" is often used to refer to a computer or PC. However it can also mean an application that provides a particular service such as DNS or a Web service.
SIP
Session Initiation Protocol
SIP is a standard for data transfer in Internet telephony (VoIP). It describes how a call is
carried over the data network and which components plus which transport and signalling protocols are involved.
SMTP
Simple Mail Transfer Protocol
The SMTP Protocol is part of the TCP/IP protocol family. It governs the exchange of electronic mail on the Internet. Your Internet Provider provides you with access to an SMTP
server.

SNMP
Simple Network Management Protocol
The SNMP Protocol is part of the TCP/IP protocol family. It provides a simple procedure
for administering the network based on a system of shared information for management data and network management messages (known as traps) and reports the occurrence of events within the monitored network (for example an alarm message or notification of configuration changes).
SSID
Service Set Identifier
The SSID is used to identify the stations in a wireless network (WLAN). All wireless network components with the same SSID form a common network. The SSID can be
assigned by the network operator.
Static IP address
A static IP address is assigned to a network component manually during network configuration. Unlike a Dynamic IP address, a static (fixed) IP address never changes.
Subnet
A subnet divides a network into smaller units.
Subnet mask
The subnet mask determines how parts of the IP addresses of a network represent the
network number and how many the computer number.
The subnet mask in a network administered by the Gigaset SX541 WLAN dsl is always
255.255.255.0. That means the first three parts of the IP address form the network
number and the final part is used for assigning computer numbers. The first three parts
of the IP address of all network components are in this case always the same.
Switch
A switch, like a Hub, is an element used to link different network segments or components. Unlike a Hub however, the Switch has its own intelligence that enables it to forward packets to only the subnet or network component they are meant for.

TCP
Transmission Control Protocol
The TCP Protocol is part of the TCP/IP protocol family. TCP handles data transport
between communication partners (applications). TCP is a session-based transmission
protocol, i.e. it sets up, monitors and terminates a connection for transporting data.

TCP/IP
Protocol family on which the Internet is based. IP forms the basis for every computer-tocomputer connection. TCP provides applications with a reliable transmission link in the
form of a continuous data stream. TCP/IP is the basis on which services such as WWW,
Mail and News are built. There are other protocols as well.
UDP
User Datagram Protocol
UDP is a Protocol of the TCP/IP protocol family that handles data transport between communication partners (applications). Unlike TCP, UDP is a non-session based protocol. It
does not establish a fixed connection. The data packets, so-called datagrams, are sent
as a Broadcast. The recipient is responsible for making sure the data is received. The
sender is not notified about whether it is received or not.
UPnP
Universal Plug and Play
UPnP technology is used for the spontaneous linking of home or small office networks.
Devices that support UPnP carry out their network configuration automatically once
they are connected to a network. They also provide their own services or use services of
other devices in the network automatically.
URL
Universal Resource Locator
Globally unique address of a Domain on the Internet.
Virtual server
A virtual Server provides a service on the Internet, that runs not on itself, but on another
network component. The Gigaset SX541 WLAN dsl can be configured as a virtual server.
It will then direct incoming calls for a service via Port Forwarding directly to the appropriate Port of the network component in question.
VoIP

WEP
Wired Equivalent Privacy
WEP is a security protocol defined in the IEEE 802.11 standard. It is used to protect wireless transmissions in a WLAN against unauthorised access through Encryption of the
data transmitted.
WLAN
Wireless LAN
Wireless LANs enable network components to communicate with a network using radio
waves as the transport medium. A wireless LAN can be connected as an extension to a
wired LAN or it can form the basis for a new network.The basic element of a wireless
network is the cell. This is the area where the wireless communication takes place. A
WLAN can be operated in Ad-hoc mode or Infrastructure mode.
WLAN is currently specified in Standard IEEE 802.11. The Gigaset SX541 WLAN dsl complies with Standard 802.11g.
WPA
WPA was developed to improve the security provided by WEP. WPA uses complex procedures to generate keys, such as TKIP (Temporal Key Integrity Protocol). In addition, WPA
can use an authentication server (for example a RADIUS server) to increase security.
WPA-PSK
WPA Pre-shared Key
Variant of WPA data encryption, in which new keys are automatically generated at regular intervals by means of a keyword (Pre-shared Key). The key is updated after defined
periods (Rekey Interval).
