the Ethernet LAN port on the Gigaset SX553 WLAN dsl are connected using an Ethernet
cable (CAT5). There is one supplied. You can obtain additional Ethernet cables from your
retailer.
The Gigaset SX553 WLAN dsl allows all PCs to access the Internet simultaneously.

Wireless local area network (WLAN)
In a wireless local area network (WLAN) PCs are linked without wires or cables. The PCs
have to be equipped with a wireless local area network adapter (WLAN adapter), e.g. a
Gigaset USB Adapter 108.
We generally differentiate between two types of wireless network:
u Infrastructure mode
u Ad-hoc mode
Infrastructure mode
The infrastructure mode connects wireless and wired networks with one another. In
addition to the mobile stations, the infrastructure mode needs an access point such as
the Gigaset SX553 WLAN dsl. In infrastructure mode, the stations in the network always
communicate via this access point. The access point sets up the wireless network on a
permanent basis. Each station that wants to be part of the wireless network must first
register with the access point before it can exchange data. The range of the wireless network can be increased by using an access point.
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 SX553 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 for the Gigaset SX553 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 that has been configured without an access
point or a router.The mobile network components that communicate with each other
dire ctly and wirele ssly for m the n etwo rk on an "a d-hoc " basi s, i.e. as and when re quired.
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 there is no existing network infrastructure, and where the participants are on the move.

Ethernet
The Gigaset SX553 WLAN dsl has four Ethernet interfaces (LAN ports). Up to four PCs
can be connected directly to these LAN ports.
All PCs can access the Internet via the Gigaset SX553 WLAN dsl.
Please note:
You can also connect an Ethernet router to a LAN port to access a larger Ethernet.
If you want to link the Gigaset WLAN network to an existing network, a large number
of settings have to be applied. Therefore we cannot provide a general example for this
use; the configuration depends greatly on the networks in question. We advise having
the configuration of such a network carried out by a specialist.

Extending the wireless network coverage with a repeater
Using a repeater, e.g. the Gigaset WLAN Repeater, you can extend your wireless network's coverage. Set it u p within the range of your n etwork. The repeater will now tr ansmit data traffic into its own wireless area. This technology allows you to set up wireless
networks that cover a much larger area than is possible with a single Gigaset SX553
WLAN dsl.

Internet telephony and connecting analogue phones
The Gigaset SX553 WLAN dsl allows fixed network and Internet telephony (VoIP) via DSL
to be combined for two analogue phones.
This provides you with the full benefits of both technologies. You can make use of the
low-cost call rates of Internet telephony without any additional equipment. You can also
use your analogue or ISDN fixed network connection. The type of calls that are cheaper
for you will depend on what calls you make and when you make them, and the rates
offered by your service provider. The Gigaset SX553 WLAN dsl gives you the complete
freedom of choice at any time.
Internet
Fixed network
You can choose whether to connect two analogue phones or base stations for cordless
phones to the two phone ports. If you have an ISDN port, you can configure this connection via the Gigaset SX553 WLAN dsl configuration program.
You will need the relevant access data for your VoIP provider to configure Internet
telephony.
You can, of course, also continue to use Internet telephony on one of the PCs connected
to the Gigaset SX553 WLAN dsl. To do this, the PC must be equipped with a loudspeaker
and a microphone or headset and a full duplex sound card, and have the necessary software installed.
Please note that you can only be reached via the Internet (VoIP) when an active Internet
connection is established. You can still be called via the fixed network, however. When
a call is made, the Gigaset SX553 WLAN dsl automatically dials the fixed network if the
Internet connection is deactivated or the VoIP port is not registered.

The Gigaset SX553 WLAN dsl
Features and applications
The Gigaset SX553 WLAN dsl's wide range of features makes it ideal for a large number
of applications, such as:
u Internet access
The Gigaset SX553 WLAN dsl allows several users to have Internet access via the
integrated ADSL modem.
– Since many DSL providers permit communication with end users via PPPoE pro-
tocol, the Gigaset SX553 WLAN dsl has an integrated Client for this protocol, so
you no longer have to install this service on your PC.
– If your Internet service provider permits this, the Gigaset SX553 WLAN dsl sup-
ports shared Internet access for up to 252 users. So several users in your network
can surf the Internet at the same time, all using the same Internet account.
u Setting up a local area network
The Gigaset SX553 WLAN dsl offers the following possibilities:
– Four devices connected via Ethernet ports with a transmission speed of 10 or
100 Mbps (with automatic recognition).
– Up to 252 mobile terminals via a radio interface with a transmission speed of up
to 108 Mbps. It complies with Standard IEEE 802.11g and can work with all products that satisfy Standard IEEE 802.11b or 802.11g. The Super G technology
allows for high transmission speed.
– Using a Gigaset SX553 WLAN dsl makes it easy to set up a network at home or in
small offices. For example, users can exchange data or share resources on the
network, such as a file server or printer. You can connect a USB memory or a
printer to the USB interface of the Gigaset SX553 WLAN dsl and make them available to all users in your network.
The Gigaset SX553 WLAN dsl supports DHCP for dynamic IP configuration of the
local area network, and DNS for domain name mapping.
u Connecting phones and Internet telephony
The Gigaset SX553 WLAN dsl permits
– Internet telephony via the DSL port,
– fixed network telephony via the analogue or ISDN port,
– the connection of two analogue phones for Internet telephony and fixed network
calls,
– the connection of an answering machine or fax.
Data transfer for VoIP is carried out by the SIP protocol with high connection and
voice quality. If the Internet connection has been interrupted or you do not want to
make a call via VoIP, you can simply make a call on the fixed network.
14
The Gigaset SX553 WLAN dsl
u Security functions
The Gigaset SX553 WLAN dsl offers comprehensive security measures:
– Firewall protection against unauthorised access from the Internet
All the PCs in the local area network use the Public IP address of the
Gigaset SX553 WLAN dsl's for their Internet connections, which makes them
'invisible' on the Internet. The Gigaset SX553 WLAN dsl only allows access from
the Internet if it has been requested from the local area network.
With the firewall the Gigaset SX553 WLAN dsl also offers comprehensive protec-
tion against hacker attacks.
– Service filtering and URL blocking
The Gigaset SX553 WLAN dsl can filter Internet access. Here you determine which
PCs may access which Internet services.
In addition, you can deactivate access to certain Internet domains and sites
(URL blocking).
– Access control and encryption for the local area network
You can use various encryption methods and authentication methods (WEP, WPA/
WPA2, 802.1x MAC access control) to prevent unauthorised access to your wire-
less LAN or make data illegible to unauthorised parties.
u Offering your own services on the Internet
– If you want to offer your own services on the Internet, you can set up the
Gigaset SX553 WLAN dsl as a virtual server without permitting further access to
the local area network.
– DMZ
This allows you to release a PC on your local area network for unlimited access to
the Internet. Please note that in this case your local area network will no longer
be adequately protected against Internet attacks.
– With the Gigaset SX553 WLAN dsl, you can easily set up an FTP server and/or
HTTP server for access from the Internet.

It can be up to 32 alphanumerical characters long.
Note:
The connection to the wireless network adapters will be interrupted until the new
SSID has also been entered.
ì Deactivate SSID broadcast and make a note of the SSID. You will need this to con-
nect your PC with the Gigaset SX553 WLAN dsl at a later time.
ì Click Next >.
44
Security settings
Setting up security functions for the wireless network
In the next step you can set up the encryption and authentication methods for your
wireless network.
Wireless networks are even more susceptible to eavesdropping than wired networks.
With conventional network adapters an intruder only needs a device with a WLAN
adapter (e.g. 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 SX553 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 46)
u WEP encryption (Wired Equivalent Privacy, see page 47)
We recommend that you use WPA2-PSK if it is supported by all components in your wireless network.
You will find further options for setting up data encryption and authentication in the
Advanced Settings menu (see page 83).
45
Security settings
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 private users and users in small companies without
their own authentication server. After a certain period of time (Rekey interval), encryption keys are automatically generated with the Pre-shared key, automatically changed
("rekeying") and authenticated between the devices.
Note:
Every PC (network adapter) that requires access to a WPA-protected wireless network
must also support WPA. To find out whether and how you can use WPA on your PC,
read your network adapter's user guide.
ì Select WPA2-PSK if it is supported by all components in your wireless network.
Or:
ì Select WPA2-PSK / WPA-PSK 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 set up the same Pre-shared key for
all wirelessly connected PCs.
ì To go to the next step, click Next >.
46
Security settings
WEP encryption
WEP (Wired Equivalent Privacy) is an encryption 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 46), we recommend that you activate
WEP-Encryption.
You can choose either the standard 64-bit key or the more robust 128-bit key. The keys
are generated in hexadecimal or in ASCII format. You must use the same keys for encryption and decryption for the Gigaset SX553 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 the key is to be entered manually or generated
automatically by means of a Passphrase.
47
Security settings
Manual key entry
ì Select the Key type, Hex or ASCII.
.
If you select Hex as the key type 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 as the key type, 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 a 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.
Note:
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 in the wireless network adapters for the connected PCs in the
same way, otherwise they will not be given access to the wireless network of the
Gigaset SX553 WLAN dsl.
ì To go to the next step in the Security Setup Wizard, click Next >.
48
Security settings
Access control within the wireless network
In this step you can specify which PCs will have wireless access to the Gigaset SX553
WLAN dsl and hence to your LAN. The access control is based on the MAC address of the
PCs' network adapters. You can enter the MAC addresses for the PCs manually or select
them from the list of PCs that are currently logged in.
The access control is disabled by default. This means that all PCs that use the correct
SSID can log in.
ì Next to the MAC address filter select On to activate the MAC filtering.
49
Security settings
Entering MAC addresses manually
ì Enter the MAC address of the network adapter. You will find this address on the bot-
tom of the device.
ì Enter the name of the PC.
ì Click the Add button to add the entry to the list.
Selecting from the list of logged-in PCs
ì Select the required PC from the Known wireless clients list. All PCs that are cur-
rently logged on to the router with the correct SSID are displayed.
ì Click the Add button to add the selected PC to the list.
Note:
If you activate MAC access control, you must at least enter the PC on which you
are configuring the Gigaset SX553 WLAN dsl. Otherwise you will have no access
to the user interface and will receive a corresponding error message.
If you have inadvertently denied all PCs access to the Gigaset SX553 WLAN dsl,
you have two options:
u You can completely reset the Gigaset SX553 WLAN dsl (see page 20).
u You can connect a PC to the Gigaset SX553 WLAN dsl using one of the LAN
connections (by cable). As MAC access control only affects PCs that are connected wirelessly, you can use this PC to change the configuration.
ì To go to the next step, click Next >.

DNS Server
DNS is a decentralised service that assigns PC names or Internet addresses (Domain
names) and IP addresses to one another. A DNS server has to administer this information
for each server or each LAN with an Internet connection.
Your Internet provider will usually provide you with a DNS server that makes this assignment when an Internet connection is set up. If necessary, you can define the DNS server
such that it is used manually for the Internet connections.
ì In the Advanced Settings – Internet menu, select DNS Servers.
ì Activate the Use custom DNS servers function by selecting On.
ì Enter the IP addresses for your preferred DNS servers (Preferred DNS server and
Alternate DNS server).
ì Click OK to apply the settings.

62
Configuring the Advanced Settings
Attack Detection
If the firewall functions of the Gigaset SX553 WLAN dsl are activated, the device monitors and limits access to incoming data traffic via the DSL connection with a function
called "Stateful Packet Inspection" (SPI). This allows the Gigaset SX553 WLAN dsl to
detect 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 as to paralyse the computer or network to such
an extent that the network resources are no longer available. A typical hacker attack
involves, for example, a remote computer acting in place of the paralysed device and
receiving the data meant for the device.
You can use the Attack Detection function to change the standard firewall settings and
arrange to be notified by e-mail about any attempted hacker attacks.
ì In the Advanced Settings – Internet – Firewall menu, select Attack Detection.
63
Configuring the Advanced Settings
ì Select the security level for the firewall:
–The Medium default level offers high security and hardly limits functionality of
certain applications.
–The High level offers maximum security and may limit functionality for certain
applications.
–The Low level offers maximum functionality but may provide low security.
– Select the Custom option if you wish to determine the criteria for defence against
hacker attacks yourself. Further setting options are then shown in the window
(see page 65).
E-mail notification of a hacker attack
You can arrange to be notified about possible hacker attacks by e-mail.
ì Enter the following in the dialogue fields:
– Select the Notification interval, i.e. at what intervals you wish to be informed

u Stateful Packet Inspection
Your device monitors and limits the access of incoming data traffic from the Internet
with SPI (Stateful Packet Inspection). This allows it to detect and block certain types
of attack from the Internet, such as Denial-of-Service (DoS). A typical DoS attack
involves a remote computer paralysing a system, acting in place of this system and
receiving data intended for this device. With the Custom level you can specify yourself whether you wish to activate SPI on your device and which exceptions should
apply.

Setting up the NAT function
The Gigaset SX553 WLAN dsl comes equipped with the NAT (Network Address Translation) function. With address mapping, several users in the local network can access the
Internet via one or more public IP addresses. All the local IP addresses are assigned to
the router's public IP address by default.
One of the characteristics of NAT is that data from the Internet is not allowed into the
local network unless it has been explicitly requested by one of the PCs in the network.
Most Internet applications can run behind the NAT firewall without any problems. For
example, if you request Internet pages 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 precisely one port for the application. A port in this con-
text is an internal PC address, via which the data is exchanged between the Internet and
a client on a PC in the local network. Communicating via a port is subject to the rules of
a particular protocol (TCP or UDP).
If an external application tries to send a call to a PC in 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 users in the
local network. These applications cannot be run if Network Address Translation (NAT)
has been activated.
Using port forwarding (the forwarding of requests to particular ports) the router is
forced to send requests from the Internet for a certain service, e.g. a game, to the appropriate port(s) on the PC on which the game is running.
Port triggering is a special variant of port forwarding. Unlike port forwarding, the
Gigaset SX553 WLAN dsl forwards the data from the port block to the PC which 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 the network, but rather to
the port numbers of the required Internet service.
69
Configuring the Advanced Settings
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 are 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 identifies
a match of port and protocol for a defined trigger port, then it will open the assigned
public ports and notes the IP address of the PC that sent the data. If data comes back
from the Internet via one of these public ports, the router allows it through and
directs it to the appropriate PC. A trigger event always comes from a PC within the
local network. If a trigger port is addressed from outside, the router simply ignores it.
Note:
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
gain access to a PC in the local network.
When the Gigaset SX553 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.
You can use the NAT settings to configure the Gigaset SX553 WLAN dsl to carry out the
following tasks:
u set up port triggering for certain applications (see page 71),
u set up the Gigaset SX553 WLAN dsl as a virtual server by configuring Port Forward-
ing (see page 73),
u open the firewall for selected PCs (see page 74).
Note:
For the functions described below, the IP addresses of the PCs must remain
unchanged. If the IP addresses of the PCs are assigned via the DHCP server of the
Gigaset SX553 WLAN dsl, you must select Never expires (see page 79) as the settings
in the Local Network menu entry for the Lease time or assign static IP addresses for
the PCs.
You can activate or deactivate the NAT function (by default the NAT function is activated).

Port Forwarding
If you configure Port Forwarding, the Gigaset SX553 WLAN dsl outwardly assumes the
role of the server. 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 on the
local network remain protected.
Internet services are addressed via defined port numbers. The Gigaset SX553 WLAN dsl
needs a mapping table of the port numbers to redirect the service requests to the servers that actually provide the service.
Port Forwarding is configured for this purpose.
ì To set up port forwarding for a service, select Port Forwarding from the
Advanced Settings – Internet – Address Translation (NAT).
ì Select the required application from the Predefined applications list.
ì Activate Enabled by clicking the check box.

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 a so-called "exposed host". Your device
will then 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, the local client is directly visible to the Internet and therefore particularly vulnerable to attacks (e.g. hacker attacks). Only activate this function if it is
absolutely necessary (e.g. to operate a Web server) and other functions (e.g. port forwarding) are not adequate. In this case you should take appropriate measures for the
clients concerned.
Note:
Only one PC per public IP address can be set up as an Exposed Host (see also the
section entitled Port Forwarding on page 73).

Dynamic DNS
Any service you provide on the Internet can be accessed by a Domain name. You r
router's Public IP address is assigned to this domain name. If your Internet service provider assigns the IP address for your local network's WAN connection 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 task is performed by the dynamic DNS service (DynDNS). You
can use the DynDNS service to assign the Gigaset SX553 WLAN dsl an individual static
domain name on the Internet even if it does not have a static IP address.
Various Internet providers offer a free DynDNS service.
If you use the service of a DynDNS provider, your service can be reached on the Internet
as a subdomain of one of the DynDNS service domains.
75
Configuring the Advanced Settings
One possible service is DynDNS.org (http://www.DynDNS.org). If you have activated
the device's DynDNS function, it will monitor its public IP address. When this changes,
the device will open a connection to DynDNS.org and update its IP address there.
Note:
You must have an account with the service you have chosen (e.g. DynDNS.org) before
you can use the DynDNS function of the Gigaset SX553 WLAN dsl. Follow the instructions on the provider's website. Then enter the user data when configuring the router.
To use the router's DynDNS function, select Dynamic DNS from the
Advanced Settings – Internet menu.

QoS (Quality of Service)
Many communication and multimedia applications require large, high speed 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 preference.
ì In the Advanced Settings – Internet menu, select QoS.
ì Select Differentiated services, i.e. the prioritisation of certain services for data
transfer between your network and the Internet.
Via Priority you can determine which data packets are to be given preferential transmis-
sion. By means 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, it will determine the priority automatically. Your device will note this for forwarding. In addition, the device recognises certain Predefined applications and assigns each 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 Allocated bandwidth for Predefined applications and for (all other appli-
cations).
ì Click OK to save and apply the changes.

On this screen you can change the device's IP address. The preset IP address is
192.168.2.1. This is the Private IP address of the Gigaset SX553 WLAN dsl. This is the
address under which the device can be reached in the local network. It can be freely
assigned from the block of available addresses. The IP address under which the
Gigaset SX553 WLAN dsl can be reached from outside is assigned by the Internet service
provider.
ì If you want to assign a different IP address to the Gigaset SX553 WLAN dsl, enter it
in the fields next to IP address.
ì Adjust the Subnet mask if necessary.
We recommend that you use an address from a block that is reserved for private use.
This address block is 192.168.1.1–192.168.255.254.
Note:
New settings can only be made after the Gigaset SX553 WLAN dsl has been

Configuring the DHCP server
The Gigaset SX553 WLAN dsl has a DHCP server for which the factory setting is active.
Consequently, the IP addresses of the PCs are automatically assigned by the
Gigaset SX553 WLAN dsl.
Note:
u If the DHCP server for the Gigaset SX553 WLAN dsl is activated, you can configure
the network setting on the PC so that the option Obtain an IP address automatically is set up. Further information about this can be found in the section entitled
"Configuring the local network" on page 129.
u If you deactivate the DHCP ser ver, you will have to assign a static IP address for the
PCs that use the network settings.
ì To activate the DHCP server, select On.
ì If the DHCP server is active, you can define a Lease time. The Lease time determines
the period for which the PCs retain the IP addresses assigned to them without changing them.
Note:
If you select Never expires, the IP addresses are never changed. Activate this
option if you want to make NAT or firewall settings using the IP addresses of the
PCs; otherwise you have to assign static IP addresses to these PCs.

Configuring the Advanced Settings
SSID
For the wireless network components to be able to communicate with one another, you
must use the same SSID (Service Set Identifier).
The default SSID for the Gigaset SX553 WLAN dsl is ConnectionPoint. For security reasons you should change this SSID and deactivate SSID broadcast (for information see
below).
Enter a character string of your choice. The SSID is case sensitive. It can be up to
32 alphanumerical characters long.
Note:
The connection to the wireless network adapters will be interrupted until you have
entered the new SSID in them as well.
SSID broadcast
If this option is enabled (default setting), the Gigaset SX553 WLAN dsl will send the SSID
in all data transfers and the SSID of your Gigaset SX553 WLAN dsl will be displayed on
PCs that have a wireless network adapter. In this case, hackers could use the SSID to gain
access to your network.
If you deactivate SSID broadcast, the SSID of the Gigaset SX553 WLAN dsl will not be
displayed. This increases the protection against unauthorised access to your wireless
network. Make a note of the SSID. You will need it to log on to the PC.
ì Select Off to deactivate SSID broadcast.

You can only use Super G if this function is supported by at least one client in your wireless network. For the best possible data transfer rates, all clients in your LAN should support Super G.
Please remember:
If you activate Super G as the transmission mode, but it is not supported by all
components in your wireless network, then for technical reasons the transfer rate in
the network may be significantly lower than the possible maximum of 108 Mbit/s.
ì Select the mode for using Super G (108 Mbit/s) for your wireless network to
increase the data transfer rate. You have a choice of two modes.
– Static: Wireless transmission is at a rate of just 108 Mbps. Clients that do not sup-
port this speed cannot connect to the access point.
– Dynamic: If you select this transmission mode, the router accepts participants
that communicate at different transfer rates and adjusts to the slowest client in
the network.

If you are sending data over radio channels, we recommend that you activate encryption (WEP or WPA) on the components in the wireless network. WPA offers greater security than WEP. You should therefore select WPA encryption if it is supported by all components in your wireless network.
WPA is a more efficient method than WEP for protecting wireless networks. Dynamic
keys, based on TKIP (Temporal Key Integration Protocol) offer increased security. The
new WPA2 standard is based on AES.
WPA also supports the use of an authentication server.
ì In the Wireless Network menu, select Encryption & Authentication.
The following security mechanisms are currently available:

("rekeying") and authenticated between the devices.
The standard of encryption available to you depends on the components in the wireless
network. Every PC (network adapter) that requires access to a WPA-protected wireless
network must also support WPA. To find out whether and how you can use WPA on your
PC, read your network adapter's user guide. If all components support WPA2, select

are configuring the Gigaset SX553 WLAN dsl. Otherwise you will have no access
to the user interface and will receive a corresponding error message.
If you have inadvertently denied all PCs access to the Gigaset SX553 WLAN dsl,
you have two options:
u You can completely reset the Gigaset SX553 WLAN dsl (see page 20).
u You can connect a PC to the Gigaset SX553 WLAN dsl using one of the LAN
connections. As MAC access control only affects PCs that are connected wirelessly, you can use this PC to change the configuration.

Setting up Internet telephony (VoIP)
The Gigaset SX553 WLAN dsl allows you to make telephone calls via the Internet using
an analogue telephone and, if required, via the fixed network as usual. To do this, you
require access authorisation from your service provider and the relevant access data. To
make calls you must enter this data along with other configuration settings in Advanced
Settings in the VoIP (Voice over IP) menu.
The menu comprises the following entries:
u VoIP settings: Enter the basic data from your service provider here (see page 92).
u ISDN: Enter the multiple subscriber numbers for your ISDN telephone connection
here (see page 94).
u Extensions: Set up the functions for two extensions here (see page 95).
u Dialling rules: Specify numbers here that are to be dialled only via the fixed network
or only via the Internet. You can block numbers completely (e.g. 0190 numbers) or
enter a call-by-call provider for the fixed network (see page 97).
Note:
If you do not specify any of your own dialling rules, then the default settings will
be used as entered in the Dialing Plans screen in the VoIP menu. All other calls
are made via the Internet. If you press the * key twice before dialling the phone
number, the call will always be made over the fixed network. The dialling rules will
not apply in this case.
Switching over takes a little time. For automatic dialling insert a pause after pressing the * key twice by pressing the recall key. You should therefore press the following keys: * key, * key, recall key and then the keys for the phone number.
Please also remember this when saving phone numbers in the telephone if a
number is always to be called via the fixed network. Otherwise this number might
not be dialled correctly.
u Quick dial: Specify quick dial numbers or terms here for phone numbers you use fre-
quently (see page 100).
Important information:
u If VoIP is not set up you will always make calls via the fixed network. The dialling
rules will not apply in this case (see page 97).
u All calls from the fixed network are forwarded to the phone connected to the
Phone 1 port.
u If VoIP is set up, then – depending on your provider – a call-by-call number is preset
for fixed network calls.
u Check these dialling rules (see page 97) and change them if you have agreed special
phone tariffs with another provider.
u Do not change the default setting for the Internet connection mode (= "permanent
connection") if you are using VoIP (see page 37). You can only be called via VoIP if
this setting is used. Remember, though, that this setting can result in high connection costs if you have agreed a time-based tariff with your Internet provider.

Configuring the Advanced Settings
u If there is a power failure or if you have turned off the Gigaset SX553 WLAN dsl you
can make no more calls if you have an ISDN connection. For an analogue phone connection you can only make calls using a phone connected to the Phone 1 port. The
dialling rules will not apply in this case.

Extensions
Your Gigaset SX553 WLAN dsl offers you two internal extensions that you can use for
making calls via the fixed network or via VoIP. You can assign each extension the relevant phone numbers for incoming and outgoing calls and make other settings such as
call waiting, or display the caller's number, or other technical settings.
ì In the Advanced Settings – Telep hony menu, select the option Extensions.
ì Select the Phone number (your VoIP service provider or fixed network) for incoming
and outgoing calls under Extension 1. The list of numbers for Internet telephony is
the one you set up in the VoIP menu (see page 92).
ì In the Additional phone numbers fields, you can select which numbers you want
to use for calls on this extension with a prefix (#1* – #4*).
ì Select Receive calls for all numbers if you wish to receive all incoming calls on all
extensions.
ì Select the option Call waiting if you want to permit a signal for an incoming call
when the lines are busy.

Configuring the Advanced Settings
Note:
u Call waiting is indicated if you are making a call via a VoIP connection and you
receive an incoming analogue call.
u Call waiting is not indicated for a VoIP call if you are making a call via an ana-
logue connection.
ì If your service provider supports this function you can have the caller's number dis-
played via Display number of the caller (CLIP).
ì Select Hide own number for outgoing calls (CLIR) if you wish to hide the number
of this extension for outgoing calls.
Note:
Many service providers either do not support this function or may be unreliable.
Please contact your service provider if you want to be certain that CLIP and CLIR
are actually supported.
ì Different dial tones for fixed line and VoIP: If you activate this function, a different
dialling tone is used for Internet telephony than for fixed network telephony. This
means you can immediately hear when dialling a number whether you are calling
via the Internet or via the fixed network.
ì Hook flash time determines the period of time after which the end of a call is
announced. Please only change this value if your service provider requires it.
ì Select the relevant settings for Extension 2.
ì Click OK to apply the settings.
