local area network (WLAN). The device supports Super G technology making this possi-
ble. The transmission rate in the wireless local area network can be increased to 108
Mbps thanks to channel bundling. For network security, wireless transmission can be
encrypted using the WPA standard or 64-/128-bit WEP.
The Gigaset SX553 WLAN dsl also offers the functions of a PABX for Internet telephony
(VoIP) and fixed-network telephony allowing you to connect up to two conventional
analogue terminals. Using these analogue phones, you can make calls via the Internet
or via an existing analogue or ISDN phone line.
The Gigaset SX553 WLAN dsl allows several users to access the Internet simultaneously.
A single user account can be shared if your Internet service provider permits this. If you
want to surf the Internet and make calls using the Internet, the Gigaset SX553 WLAN dsl
is a convenient and simple solution.

Wired local area network (Ethernet)
In a wired local area network, PCs communicate with one another via an Ethernet cable.
When the Siemens Gigaset SX553 WLAN dsl is used, it establishes the connection
between the PCs. For this it has four Ethernet LAN ports for connecting four PCs. The
PCs have to be equipped with a network port (Ethernet). New PCs frequently already
have this port. For older PCs you need to install an Ethernet network card. The PC and
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:
uInfrastructure mode
uAd-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 net-
work 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 sta-
tions 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
uwirelessly networked PCs to the Internet and
uwirelessly 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
directly and wirelessly form the network on an "ad-hoc" basis, i.e. as and when required.
All the stations in the network have the same rights. Ad-hoc networks are used wher-
ever communications networks have to be set up quickly and there is no existing net-
work infrastructure, and where the participants are on the move.

Linking wireless networks with the Internet
The Gigaset SX553 WLAN dsl has an ADSL interface that permits all stations within its
local area network to access the Internet simultaneously. To be able to use this function-
ality you need a DSL connection obtainable from an Internet service provider. Find out
whether your service provider supports parallel access by several PCs.

Linking a wireless local area network (WLAN) to an Ethernet (LAN)
Wireless local area networks can work easily together with existing Ethernet networks.
If you wish to connect mobile stations to an existing wired network, you must group
together all mobile stations into a wireless local area network in infrastructure mode.
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 net-
work's coverage. Set it up within the range of your network. The repeater will now trans-
mit 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.
PCs to be connected in a wireless local area network via a Gigaset WLAN Repeater must
be equipped with a wireless network adapter or a USB adapter.

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.
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 con-
nection 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 soft-
ware 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.

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.
uSetting 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 prod-
ucts 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 avail-
able 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.

uSecurity 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.
uOffering 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.
