The Gigaset SX761 dsl
The Gigaset SX761 dsl is a powerful but simple communications device for connecting
your PC or local area network (LAN) to the Internet (via DSL). It contains an integrated
ADSL modem (ADSL /ADSL2+) enabling you to access the Internet easily.
The Gigaset SX761 dsl also offers the functions of a PABX for Internet telephony (VoIP).
You can connect up to two traditional analogue terminals and then use these analogue
phones to make calls via the Internet. In addition, you can operate SIP clients (PCs with
appropriate software) as PABX extensions and therefore also make calls via the Internet.
The Gigaset SX761 dsl allows several users to access the Internet simultaneously. A sin-
gle 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 at the lowest possible cost, the
Gigaset SX761 dsl is a convenient and simple solution.
or – depending on the hardware type of your device – with the registration (Scan) but-
ton on the back panelThe Gigaset SX761 dsl has an extensive range of functions but
remains simple to use. It can be configured and operational within a few minutes.
Do your part for the environment (ECO)
Thanks to a switch-mode power supply unit, all of our broadband prod-
ucts offer significantly reduced power consumption - for more energy-
efficient use. It's our goal to ensure a sustainable economic process by
using an environmentally friendly production and management system
- which makes it easy for us to meet the strict ISO 14001 standards for international
environmental management.

Local area networks with Gigaset products
You can use the Gigaset SX761 dsl to set up a local area network, for example a home
network. All PCs in this network can communicate with each other and have access to
the Internet.
Wired local area network (Ethernet)
In a wired local area network, PCs communicate with one another via an Ethernet cable.
When the Gigaset SX761 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 SX761 dsl are connected using an Ethernet cable (CAT5). There is one supplied.
You can obtain additional Ethernet cables from your retailer.
The Gigaset SX761 dsl allows all PCs to access the Internet simultaneously.

Internet telephony and connecting analogue phones
The Gigaset SX761 dsl allows a Internet telephony (VoIP) over DSL for two analogue tel-
ephones and four other wired VoIP telephones or SIP clients.
You can make use of the low-cost call rates of Internet telephony without any additional
equipment.
Please remember:
You can also connect an Ethernet router or switch 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 exam-
ple 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.

Schablone 2005_07_27
You can choose whether to connect any two analogue phones, a fax machine or an
answering machine to the phone ports. You can configure these ports using the Gigaset
SX761 dsl.
The PABX of the Gigaset SX761 dsl allows you to connect PCs with SIP clients (software
for Internet telephony) as extensions. You can use all functions of your PABX for Internet
telephony also.
You will need the relevant access data for your VoIP provider to configure Internet
telephony.
uVia registration button
The access point (e.g. the Gigaset SX761 dsl) has a registration button. The registra-
tion button is available either:
– as hardware: a specific button (labelled Scan) is provided on the device’s back
panel.
– as software: registration can be started via the WPS Registration page of the
user interface.
In the description that follows, the term registration button refers to both the Scan
button and the corresponding function in the user interface.
Depending on your hardware version, WPS registration may only be possible via the
user interface.
Please remember:
You can only be reached via the Internet (VoIP) when an active Internet connection
is established.

button Features and applications
The Gigaset SX761 dsl's wide range of features makes it ideal for a large number of
applications.
Depending on your device, some of the features may differ from the description in this
instruction manual.
uInternet access
The Gigaset SX761 dsl allows several users to have Internet access via the integrated
ADSL /ADSL2+ modem.
– Since many DSL providers permit communication with end users via the PPPoE
protocol, the Gigaset SX761 dsl has an integrated Client for this protocol, so you
no longer have to install this service on your PC.
– The Gigaset SX761 dsl supports shared Internet access for multiple users. This
means 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 SX761 dsl offers the following possibilities:
– Four devices connected via Ethernet ports with a transmission speed of 10 or
100 Mbps (with automatic recognition).
The Gigaset SX761 dsl supports DHCP for dynamic IP configuration of the local area
network, and DNS for domain name mapping.
uConnecting phones and Internet telephony
The Gigaset SX761 dsl permits
– Internet telephony via the DSL port.
– Connection of two analogue phones for Internet telephony and for fixed network
calls as well as connection of wireless SIP phones and PCs with SIP clients for
Internet telephony.
– Connection of an answering machine or fax.
Data transfer for VoIP is handled by the SIP protocol with high connection and voice
quality.
uSecurity functions
The Gigaset SX761 dsl offers comprehensive security measures:
–Firewall protection against unauthorised access from the Internet
All PCs in the local area network use the Public IP address of the Gigaset SX761
dsl for their Internet connections, which makes them 'invisible' on the Internet.
The Gigaset SX761 dsl only allows access from the Internet if this has been
requested from within the local area network.
With the firewall, the Gigaset SX761 dsl also offers comprehensive protection
against hacker attacks.
– Service filtering
The Gigaset SX761 dsl can filter Internet access. Here you determine which PCs
may access which Internet services.

uOffering your own services on the Internet
– If you want to offer your own services on the Internet, you can set up the Gigaset
SX761 dsl as a virtual server without permitting further access to the local area
network.
–DMZ (Exposed Host)
This allows you to release a PC in your local area network for unlimited access
from the Internet. Note that in this case your local area network will no longer be
adequately protected against Internet attacks.

Overview of the installation steps
1. First ensure that an Ethernet network card is installed in the PCs you want to connect
to the Gigaset SX761 dsl. The installation is described in the user guides for these
products.
2. Then make the necessary connections (PCs, phones, splitter) on the Gigaset SX761
dsl and activate the device (page 16).
3. Before the PCs can communicate with the Gigaset SX761 dsl and with each other in
a local network, you may have to change your network settings (page 22). Configure

to do this, refer to the section entitled "Configuring the local area network" on the
CD-ROM.
4. Then configure the Gigaset SX761 dsl to activate the device's Internet access (refer
to the section entitled "Basic Setup Wizard" on page 27). To do this you will need the
access data for your Internet service provider.
5. If you want to connect more PCs to the Gigaset SX761 dsl, configure their network
settings and set up the local area network accordingly (refer to the section entitled
"Configuring the local area network" on the CD-ROM).
6. If you want to use the Gigaset SX761 dsl for Internet telephony, you must configure
your VoIP provider's registration data (refer to the section entitled "Setting up Inter-
net telephony (VoIP)" on page 61).
7. If you wish to use other functions of the Gigaset SX761 dsl, for example the compre-
hensive security features, use the Security Setup (page 34) or the Advanced Setup
