Information on Specific Absorption Rate (SAR)
Information on Specific Absorption Rate (SAR)
This device meets the limits for protecting the health of the public from the effecs of
exposure to electromagnetic fields when it is operated in connection with the designated antenna(s) like described in the user manual.
Your device is a radio transmitter and receiver. It is designed and manufactured not to
exceed the limits for exposure to emission from electromagnetic fields recommended
by international guidelines from the International Commission on Non-Ionizing Radiation Protection (ICNIRP). These limits are part of comprehensive guidelines for the protection of the public and establish permitted levels of exposure to electromagnetic radiation for the population. The guidelines were confirmed by independent scientific
organisations through periodic and thorough evaluation of scientific studies. The limits
include a substantial safety margin designed to assure the safety of all persons, regardless of age and health.
The exposure limit employs a unit of measurement known as the Specific Absorption
Rate, or SAR. The SAR limit stated in the international guidelines is 2.0 W/kg. Tests for
SAR are conducted in all frequency bands with the device transmitting at its highest
power level with minimum possible distance to the body. The actual SAR level of the
device during operation with the designated antenna(s) is below the maximum value
and is additionally decreased by a distance to the device. This is because the device is
designed to operate at multiple power levels so as to use only the power required to
enable seamless network connection.
Information about the optional outdoor antenna
Only one of the antennas listed on page 12 must be used.
The outdoor antenna must be installed and put into service by a qualified
electrician.
 Only commence the outdoor work once you have taken all the nec-
essary steps to make the location safe.
Be sure to observe the safety instructions.
Wall duct:
To connect the SE681 WiMAX to the outdoor antenna, the antenna cable must be fed
through the wall to the outside of the building. It must be possible to make a suitable
wall or window duct at or near the location of the SE681 WiMAX.
Information about the optional outdoor antenna
Setting up the antenna mast:
There should not be any obstructions (walls, trees etc.) in front of the antenna.
The best results will be obtained if the outdoor
antenna is in sight of the WiMAX base station
(cf. Fig. 1).
Fig. 1
If a line of sight is not possible, you can reflect the
radio waves off neighbouring buildings. To do
this, direct the antenna at the building it is to
reflect off and not at the base station (cf. Fig. 2).
Fig. 2
The antenna mast must be structurally secure. Check how secure the various attachments are.
The antenna mast must be within reach of the cable. Ideally, the antenna cable should
be protected outside (from frost, sun, unauthorised and mechanical influences etc.).
In particular, make sure the antenna mast has sufficient load capacity. If you are mounting the mast on the roof, make sure the roof is fully sealed again afterwards.
Lightning protection
The antenna mast should be positioned near a lightning conductor. A suitable lightning
conductor must be installed where necessary.
The outdoor antenna is not designed to be struck directly by lightning and must be protected accordingly. The antenna must therefore be mounted in areas that are protected
against lightning (Lightning Protection Zone 0B). The corresponding separation distance (IEC 62305) must be complied with.
Earthing and lightning protection work may only be carried out by electricians specifically qualified for such work.
Information about the optional outdoor antenna
The appropriate earthing clamps must be used to create an equipotential bonding
between a cable shield and an equipotential bonding bar that complies with regulations.
Please observe the standard DIN VDE 0855-300 and find out more on the Internet at
http://www.dehn.de.
Antenna cable and antenna connection:
It must be possible to connect the outdoor antenna to the SE681 WiMAX by means of
an antenna cable.
Please note that the antenna connection must be protected from the impact of rain and
other weather effects.
Use cable clamps to attach the cable to the mast. Please note that the cable must be
long enough to turn the antenna at a later stage.
Antenna alignment:
When aligning the antenna, we recommend asking a second person to run the Basic
Setup Wizard on the PC and to check the reception quality on the screen; see Chapter
"Basic Setup Wizard" on page 25.
Aligning the antenna using acoustic signals
If neither you nor the assistant are able to check the signal strength on
screen while the antenna is being aligned, you can monitor it via a radio
system. To do this you will need, for example, two cordless phones,
mobile phones or radio devices:
 Activate Tone on on the configuration PC.
 Establish an internal connection between the two handsets and
switch on the loudspeaker on both devices.
 Leave one handset next to the configuration PC and carry the other
with you (belt clip).
You will now be informed of the signal strength by means of beeps. The
closer together the sequence of beeps, the better the connection quality.
After installation:
Tighten all screw connections to the torques listed in the installation instructions.
Secure the antenna cable with cable clamps and cable ties. The cable must be protected from exposure to pressure and tension.
SE681 WiMAX

 Connect the mains adapter plug to the SE681 WiMAX socket.
 Power up the PC.
 Connect the mains adapter to the mains power supply.
The system starts up and performs a self-test. After the self-test, the SE681 WiMAX
continually attempts to register with a WiMAX network. Registration may be successful immediately. If not, registration will take place when the SE681 WiMAX is
being configured.
 Check the LEDs during startup:
LEDs during startup:
– The Power power supply LED lights up green, and the SE681 WiMAX starts a
self-test. If the LED does not light up, check that the mains adapter is connected
correctly and the power socket is live.
– The LAN Ethernet LED is continuously lit green. If the LED does not light up,
check that the Ethernet cable is connected correctly.
– If registration with a WiMAX network has already been successful, the Online
LED lights up green. If the LED does not light up, register your SE681 WiMAX
during configuration.
Restarting and resetting the SE681 WiMAX
The reset button is located inside the SE681
WiMAX so that it cannot be pressed accidentally.

more on this see "Setting the operating mode" on page 31.
25
Basic Setup Wizard
Selecting the antenna
 Select whether you want to operate your SE681 WiMAX with an outdoor antenna
or the integrated one.
– Click the first option button if you want to use the integrated antenna. Your
SE681 WiMAX must be positioned by the window with the cable connections
pointing inwards and must be connected.
– Click the second option button if your SE681 WiMAX came with an outdoor
antenna. This antenna must have been installed and connected by an electrical
specialist.
 Click Next.
Adjusting the antenna
 If you are using the integrated antenna, adjust your SE681 WiMAX by the window.
If you are using the outdoor antenna, this must already be installed and facing
towards the base station, see "Installing the SE681 WiMAX" on page 12.
 Click Next.
Establishing a radio connection to a WiMAX network
The Basic Setup Wizard will now scan the frequencies to establish an initial radio connection to a WiMAX network.
The frequency scan begins automatically. A progress bar indicates how far the scan
has progressed. In addition, you will see in the Remaining time area roughly how
much time is still needed for the complete scan. Depending on how your SE681 WiMAX
has been preconfigured by your provider, the scan can last several minutes before the
first radio connection is established.
During the scan, the SE681 WiMAX or antenna must not be moved; this
is the only way to guarantee a complete scan with the current antenna
alignment.
As soon as a radio connection has been established with a WiMAX network, the scan
will end. The progress bar is fully filled in and the display in the Remaining time area
jumps to 0 seconds.
 If the scan has been successful, read on in Chapter "Precisely aligning the antenna"
on page 28.
26
Basic Setup Wizard
If the scan was not successful:
Both the integrated antenna and the outdoor antenna are directional antennas; this
means that they must at least be pointing roughly in the direction of a WiMAX network
base station in order to establish a radio connection. The access data must also have
been entered correctly.
If the scan was not successful:
 First check your access data by going back to the WiMAX configuration page
( page 25).
 If you have entered your access data correctly, adjust the antenna.
If you are using the integrated antenna:
 Turn your SE681 WiMAX by approx. 45°.
Correct:
Incorrect:
 Click Ok to restart the scan.
You must not move the SE681 WiMAX during the scan. You should
therefore always place the SE681 WiMAX upright and on a level surface
directly by the window.
If the scan has still not been successful with the alignment changed:
 Place the SE681 WiMAX by a window that faces a different direction.
 If necessary, repeat the scan with all possible locations and alignments.
 If necessary, ask your provider for the location of the nearest WiMAX network base
station and select a location for your SE681 WiMAX that points towards this base
station.
The best results will be obtained if the SE681 WiMAX is in sight of a WiMAX network
base station.
27
Basic Setup Wizard
If a line of sight is not possible, you can reflect the radio waves off neighbouring buildings. To do this, direct the SE681 WiMAX at the building it is to reflecting off and not at
the WiMAX network base station.
If you are using the outdoor antenna:
 The qualified electrician turns the antenna through 20° in the vertical axis. Then the
scan is repeated by clicking the Ok button.
 If necessary, the scan should be repeated with all possible antenna alignments.
Precisely aligning the antenna
Once you have established a radio connection to a WiMAX network, align your SE681
WiMAX or antenna precisely using the Basic Setup Wizard.
Take extra care to align the SE681 WiMAX or outdoor antenna precisely.
The better the connection quality, the faster your Internet connection will
be in the future.
To obtain precise alignment of the SE681 WiMAX or antenna, turn it a little at a time. If
you use the antenna integrated in the SE681 WiMAX, you can also move the device a
little at a time to optimise the reception quality.
 When a connection to a WiMAX network has been established, click Next to make
fine adjustments to the antenna.
28
Basic Setup Wizard
The quality of the radio connection is represented graphically by the Signal quality bar.
The longer the bar is, the better the radio connection. Try to obtain the best possible
radio connection setting.
 If you are using the antenna integrated in the SE681 WiMAX:
Memorise the current location and alignment of your SE681 WiMAX, so that you
can restore it if the connection is broken.
 If you are unable to check the display of the signal quality on the screen while align-
ing the antenna:
Activate the Audible feedback option to obtain information about the signal quality
by means of beeps. The closer together the sequence of beeps, the better the connection quality.
 Turn or move the SE681 WiMAX or turn the antenna a little at a time and note the
signal quality display. Use this to move the antenna to the position with the best signal quality.
In addition to the beeps and on-screen bar graph you can also determine the quality of
the connection by how many of the 4 LEDs indicating signal quality are lit up on the
device (RSSI 1–RSSI 4). The more LEDs that light up, the better the connection quality.
If you have turned your SE681 WiMAX or the antenna too far, the connection might
break. You should then return to the alignment that provided a connection and repeat
the procedure for establishing a connection to the WiMAX network. Then make any fine
adjustments step by step.
The connection quality can be detected in two different ways:
 CINR (Carrier to Interference and Noise Ratio) measures the signal
quality.
 RSSI (Received Signal Strength Indication) measures the signal
strength.
The bar indicates either RSSI or CINR values. The used method is preconfigured by your operator. If RSSI is used the bar is labeled Signal
strength.
When your SE681 WiMAX or outdoor antenna is optimally aligned:
 Click End to close the Basic Setup Wizard and apply the settings you have made.
Make sure that in future your SE681 WiMAX or outdoor antenna is always in the set
position.

Setting the operating mode
Setting the operating mode
Via the operating mode, you define the role your SE681 WiMAX will play when establishing and administering Internet connections.
You can run your SE681 WiMAX in the following operating modes:
Router
Your SE681 WiMAX serves as an Internet router for the network components connected to the LAN port, i.e. it establishes the connection to the
Internet and ensures the transfer of the communication data to and from the
Internet (default).
Bridge
The network components initiate and control their Internet connection themselves. Your SE681 WiMAX only allows the communication data to and
from the Internet to pass through.
 To change the operating mode, open the Advanced Settings tab and select Oper-
ating Mode from the menu.
When you change the operating mode, your device is restarted.
In Bridge mode, the following functions are no longer available:
 The DHCP server of the SE681 WiMAX is deactivated ( page 36) because the
network components receive IP addresses in the public network.
If you want to access the configuration program of the SE681 WiMAX via your PC,
you must connect the PC directly to the LAN port. You must also temporarily assign
it a static IP address in the address range of the SE681 WiMAX. If you want to use
the Internet again after this, reset your PC to “automatic IP address”. For details see
the document “Configuring the local area network” on the product CD.
 The firewall of your SE681 WiMAX is disabled and cannot be enabled ( page 33).
 The NAT function of your SE681 WiMAX is disabled. This means that the functions
Port Forwarding ( page 34) and Exposed Host ( page 35) are not available.
If necessary you may have to protect your network components against unwelcome
access from the Internet by appropriate means (e.g. firewall software).
31
Configuring Internet access

mode:
32
Configuring Internet access
Always on
This gives the users in your network a constantly active Internet connection.
Only choose this setting if your Internet tariff is not time-dependent.
If necessary you can terminate the Internet connection manually ( page 24).
Connect on demand
The Internet connection is only established if an application, e.g. an Internet
browser or an e-mail program, requests it.
PPPoE pass-through
If you activate the PPPoE pass-through function, a PC in the network can connect to
the Internet via its own connection ID. The router puts this connection through.
Setting up DNS servers
DNS (Domain Name System) is a decentralised database on the Internet which allocates clearly understandable Internet names (domains) to the actual addresses of PCs
and services (e.g. IP addresses). The DNS servers required for access to this database
are normally provided by your provider and do not have to be set up specially. But if
necessary you can change them here.
 Open the Advanced Settings tab and on the Internet menu select DNS Servers.
 Activate the Use custom DNS servers function and enter the IP addresses for your
Preferred DNS server and the Alternate DNS server.
Enabling or disabling the firewall
Your SE681 WiMAX comes with an integrated firewall, which protects your device and
network against unauthorised access from the Internet. If the firewall is enabled, your
device can identify certain events, e.g. suspicious incoming data packets from the Internet, as attacks and avert them (hacker defence). Your device’s firewall is enabled by
default.
We urgently recommend that you leave the firewall of your SE681
WiMAX enabled, otherwise your network will no longer be protected
against hacker attacks from the Internet.
If you still want to disable the firewall:
 Open the Advanced Settings tab and on the Internet menu select Firewall.
 Disable the firewall.
33
Port Forwarding
This function is not available in Bridge operating mode, see "Configuring
Internet access" on page 32.
PCs in your network should be protected by a separate firewall. You can
set up protection against DoS (Denial of Service) attacks in Bridge mode
via the local network configuration, see "LAN configuration" on page 36.
Port Forwarding
The SE681 WiMAX comes with the NAT (Network Address Translation) function, which
is always activated in Router operating mode. With address mapping, multiple users in
the local network can access the Internet via the public IP address. All the local IP
addresses are assigned to the router's public IP address by default. All IP addresses
of PCs in the local network are converted to the router's public IP address when
accessing the Internet.
Most Internet applications can be executed behind the NAT firewall without any problems. However, some applications - such as Internet games - require users in the Internet to send requests to users in the local network so that the players can communicate
with each other. Sometimes these applications also require several ports to communicate through. Such applications do not work if NAT is active.
Using port forwarding (the forwarding of requests to particular ports) the router is forced
to send requests from the Internet for a certain service, for example a game, to the
appropriate port(s) on the PC on which the game is running. If you configure Port Forwarding, the SE681 WiMAX 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 SE681 WiMAX needs
a mapping table of the port numbers to redirect the service requests to the servers that
actually provide the service. Port Forwarding has to be configured for this purpose.
 Open the Advanced Settings tab and on the Internet menu select Port Forward-
ing.
 Define the list of services for which you want requests from the Internet to be for-
warded.
Important services are already included in the Predefined applications selection field.
The list can hold up to 16 entries.
34
The IP addresses of the PCs for which you set up port forwarding must
remain unchanged. If the IP addresses of the PCs are assigned via the
DHCP server of the SE681 WiMAX, you must select the option Never
expires as the Lease time when configuring the DHCP server or assign
static IP addresses to the PCs, see "Configuring the DHCP server" on
page 36.
Port Forwarding
This function is not available in Bridge operating mode, see "Configuring
Internet access" on page 32.
Opening the firewall for a selected PC (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 requests from the Internet to this client, with the
exception of requests to the port numbers already defined via port forwarding. 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.
 Open the Advanced Settings tab and on the Internet menu select Exposed Host.
 Define the list of PCs you want to set up as exposed hosts.
 Activate a PC which you want to function as the current exposed host. Only one PC
at a time can be selected.
The IP addresses of the PCs you want to set up as exposed hosts must
remain unchanged. If the IP addresses of the PCs are assigned via the
DHCP server of the SE681 WiMAX, you must select the option Never
expires as the Lease time when configuring the DHCP server or assign
static IP addresses to the PCs, see "Configuring the DHCP server" on
page 36.
This function is not available in Bridge operating mode, see "Configuring
Internet access" on page 32.

With the help of the LAN configuration you can change the preset values for the computer name and the private IP address for your SE681 WiMAX and configure the integrated DHCP server.
 Open the Advanced Settings tab and select Local Network.
The preset IP address is 192.168.2.1. This is the private IP address of the SE681
WiMAX. 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 SE681 WiMAX can be reached from outside is assigned by the Internet service provider. The default Subnet mask for the local network administered by the
SE681 WiMAX is 255.255.255.0.
Please note which subnet mask is set when assigning the IP address. The preset subnet mask defines the first three parts of the IP address which must be identical for all
network components (including routers).
We recommend that you use an address from a block that is reserved for private use.
This address block is 192.168.1.1 to 192.168.255.254.
Configuring the DHCP server
The SE681 WiMAX has a DHCP server for which the factory setting is active. Consequently, the IP addresses of the PCs are automatically assigned by the SE681 WiMAX.
 If the DHCP server for the SE681 WiMAX is activated, you can con-
figure the network setting on the PC so that the option Obtain an IP
address automatically is set up.
 If you deactivate the DHCP server, you will have to assign a static IP
address for the PCs that use the network settings.
For more information see the document “Configuring the local area network” on the CD.
 If the DHCP server is active, you can define a Lease time. The lease time indicates
how long the client may use the allocated IP configuration.
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.
 Define the range of IP addresses the SE681 WiMAX should use to automatically
assign IP addresses to the PCs. Define the Start IP and the End IP.
36
LAN configuration
Assigning static IP addresses to individual PCs
Even if you have activated the DHCP server, you can still assign a static IP address to
individual PCs (e.g. when setting up these PCs for NAT functions).
 Enter the MAC address of the PC to which you want to assign a static IP address
and the IP address you wish to assign to the PC.
Configuring the local network in Bridge operating mode
In Bridge operating mode ( page 32) the SE681 WiMAX DHCP server is deactivated.
The network components get their IP addresses from a DHCP server in the public network.
Ageing time for When a PC in the network is accessed, your SE681 WiMAX writes the
MAC table
MAC address and port number in a MAC table to speed up further
accesses. The entry in the MAC table is deleted after a fixed time. If
necessary you can change this value via the MAC table ageing time
parameter.
Protection
against DoS
attacks
DoS (Denial of Service) attacks are attacks on a system in the network to make its services unusable. This is basically done by overloading the system by constantly sending requests. In Bridge mode,
the SE681 WiMAX provides protection against DoS attacks, which
you can enable or disable via the activate DOS protection parameter.
Forwarding on busy cannot both be activated in parallel.

– Enter cmd in the input field and click OK.
The Command prompt window opens.
 Check whether the SE681 WiMAX responds with the ping command. Enter
ping 192.168.2.1 and press Enter.
The PC now sends some test packets via this connection and checks whether the connection partner responds. The connection partner may respond in the following ways:
 Reply from the IP address of your SE681 WiMAX; statistics about the connection
are presented. If you receive these statistics, the connection to the device is OK.
 The request exceeds the time limit; it was not possible either to send or receive
any packets. There is no physical connection between the PC and your SE681
WiMAX. Check the following points:
– Is the Ethernet cable between the SE681 WiMAX and the PC properly connected?
The LAN LED on the SE681 WiMAX must light up.
– Has TCP/IP been properly configured on your PC?
If the SE681 WiMAX has the IP address 192.168.2.1, your PC's IP address must
be between 192.168.2.2 and 192.168.2.254. The subnet mask must be
255.255.255.0.
To find out the IP address of your PC, enter ipconfig in the command prompt.
If the SE681 WiMAX has not responded successfully to the ping command, you need
to adjust the network settings on the PC. To find out how to do this, please read the
document "Configuring the local area network" on the product CD.
If the SE681 WiMAX has responded successfully to the ping command, the network
is configured correctly. If it is not possible to access the configuration program of your
SE681 WiMAX, check and change the settings in your Web browser. To find out how
to do this, please read the next chapter.

Glossary
Address Translation (NAT)
Network Address Translation. NAT is a method for converting IP addresses (mainly private IP addresses) in a network to one or more public IP addresses on the Internet.
With NAT, several network components in a LAN can share a public IP address to connect to the Internet. The network components of the local network are hidden behind
the IP address registered on the Internet. NAT is often used as part of the firewall in a
network because of this security function.
Bridge
A bridge connects several network segments to form a joint network, e.g. to make a
TCP/IP network. The segments can have different physical characteristics, e.g. different linking such as Ethernet and wireless LANs. Local networks can be expanded by
linking individual segments via bridges.
dB
Decibel (a tenth of a Bel). Logarithmic unit of measurement for ratios between two currents, voltages, sound levels or powers. In order to depict large value differences
clearly and graphically, these are given in dB; e.g. 60 dB corresponds to the factor 1000
relative to the voltage drops.
dBm
Decibel milliwatt. Power level in decibels relative to 1 milliwatt.
DHCP
Dynamic Host Configuration Protocol. DHCP handles the automatic assignment of IP
addresses to network components.
DHCP was developed because in large networks – especially the Internet – the defining of IP addresses is very complex as subscribers 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 subscribers 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.
DHCP server
There is a DHCP integrated into the SE681 WiMAX that automatically assigns IP
addresses to PCs in the local network.
64
Glossary
DNS
Domain Name System. DNS permits the assignment of IP addresses to PC or domain
names that are easier to remember. A DNS server must administer this information for
each local network with an Internet connection. As soon as a page on the Internet is
called up, the Web browser obtains the corresponding IP address from the DNS server
so that it can establish the connection.
On the Internet, the assignment of domain names to IP addresses 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.
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.
Downlink
Files that your SE681 WiMAX receives and forwards to your local network.
DSL
Digital Subscriber Line. DSL is a technique whereby data is transmitted via the conventional phone line. To do this, you require suitable phone lines and special technology to
be set up by a Provider. As these preconditions are not satisfied in all areas, it is not
possible to use DSL in all locations. In order to make use of high-performance Internet
access in these areas as well, technologies such as WiMAX, Wi-Fi or satellite connections are implemented.
Ethernet
Ethernet is a network technology for local networks (LANs) defined by the IEEE as
standard IEEE 802.3. Depending on the network adapter used, the transmission speed
on the Ethernet varies between 10 Mbps and 1 Gbps.
Firewall
Firewalls are used by network operators as protection against unauthorised external
access. This involves a whole bundle of hardware and software actions and technologies that monitor and control the data flow between the private network to be protected
and an unprotected network such as the Internet.
Firmware
Device software. To correct errors or update the device, a new firmware version can be
loaded onto the device's memory (firmware update).
Flat rate
Flat rate is a particular billing system for Internet connections. The Provider charges a
set monthly fee for a certain service package.
65
Glossary
FTP
File Transfer Protocol. Protocol for exchanging files via the Internet. FTP is used, for
example, to make files available for download or to receive files from other users.
Full duplex
Data transmission operating mode in which data can be sent and received at the same
time.
FXS
Foreign Exchange Station. Phone port to which an analogue terminal (phone, fax or
answer machine) can be connected.
Gateway
A gateway connects networks with one another. In contrast to a Router, a gateway is
not dependent on protocol, i.e. it is also able to establish connections between networks with a different architecture (protocols, application interfaces etc.).
Half duplex
Operating mode for data transfer. Only one party can receive or send data at a time.
HTTP
Hypertext Transfer Protocol. Network protocol for the transmission of data, which is
mainly used for transmitting and displaying Internet content.
HTTP proxy
An HTTP proxy is a server that network components use for their Internet traffic. All
requests are sent via the proxy.
Hub
A hub is a central distribution point in a network, to which PCs and other network
devices are connected. The hub forwards received data to all connected PCs. For this
reason, in large networks, a Switch is recommended to ensure that data is only sent to
the PC requesting it.
IEEE
Institute of Electrical and Electronics Engineers. The IEEE is an international body for
defining network standards, especially for standardising LAN technologies, transmission protocols and speeds, and wiring.
66
Glossary
IEEE 802.16
Standard defined by the IEEE for WiMAX. Similarly to other standards in the 802 series
(e.g. 802.3 Ethernet, 802.11 WLAN), the WiMAX standard is one of the standards for
networks. The standard has progressed in accordance with new developments; there
are currently two main versions:
 IEEE 802.16-2004: WiMAX, which specifies the secure location for connection part-
ners.
 IEEE 802.16e-2005: Mobile WiMAX, which enables wireless cells to be exchanged
during data transmission.
IP
Internet Protocol. The protocol is responsible for addressing of subscribers in a network
using IP addresses, and routes data from the sender to the recipient. In doing so, it
decides on the way in which data packets will be forwarded between sender and recipient.
IP address
An IP address is the unique network-wide address of a network component in a network based on the TCP/IP protocol (e.g. in a local network or on the Internet). The IP
address consists of four parts (each of up to three-figure strings of digits from 0–255)
that are separated from one another by full stops (e.g. 192.168.2.1). The IP address is
made up of the network number and the number of the network component. Depending
on the Subnet mask, one, two or three parts form the network number, the remainder
form the network component number. You can find out the IP address of your PC using
the ipconfig command.
There are two different types of IP address:
 Private IP address:
IP address of a network component within a local network.
 Public IP address:
IP address that uses a network component for accessing the Internet.
IP addresses can be assigned manually or automatically:
 Static IP address:
The IP address is manually assigned to a network component and never changes.
 Dynamic IP address:
The IP address is assigned to the network component by a DHCP server. The IP
address of this network component can change each time it registers with a network
or at specific time intervals.
On the Internet, domain names are normally used instead of the IP addresses. DNS is
used to assign domain names to IP addresses.
IPTV
Internet Protocol Television. You receive your provider's television service via the DSL
connection. To do this, you require an IPTV-capable set-top box and the configuration
data of your IPTV provider.
67
Glossary
ISP
Internet Service Provider. See Provider.
LAN
Local Area Network, 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). A local network can be connected to other local networks or a widearea network (WAN) such as the Internet.
LED
Light Emitting Diode. An LED is an electronic component (semi-conductor) that generates light at low power consumption. LEDs are often used as signal lights for display
and UI elements.
Login
Access to a PC or a service, password e.g. for access to the Internet.
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), e.g. 00-90-96-3400-1A. The MAC address is assigned by the network adapter manufacturer and cannot
be changed.
Mbps
Million bits per second. Specification of the transmission speed in a network.
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 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. A network adapter has a
unique address, the MAC address.
Network protocol
The network protocol is the standard via which different PCs exchange data in a network. A connection can only be established between PCs in a network if they all use
the same protocol. The TCP/IP network protocol is the most extensive network protocol, which is also used for connections to the Internet. This must be set up on each PC
from which a network connection is to be established.
68
Glossary
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 (e.g. 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 SE681 WiMAX 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 network to offer services on the Internet without them needing a public IP address. See also: Virtual server
Protocol
A protocol describes the agreements for communicating on 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, e.g. the TCP/IP protocols for the Internet.
Provider
A provider (Internet Service Provider) offers access to the Internet for a fee.
RJ
Registered Jack. Standardised connection, also known as a modular jack.
Router
A router directs data packets from one local area network (LAN) to another via the fastest route. A router enables the connection between networks of different network technologies and this is performed on the basis of a common protocol. For example, it can
link a local network with WiMAX technology to the Internet.
RSSI
Received Signal Strength Indication. Characteristic value for the signal strength of
radio connections, used by communication devices for the automatic selection of a suitable channel.
Server
A server makes services available to other network components (clients). The term
"server" is often used to refer to a PC. However it can also mean an application that
provides a particular service such as DNS, DHCP or a Web service.
SMTP
Simple Mail Transfer Protocol. The SMTP protocol is a TCP/IP protocol and regulates
the exchange of electronic post on the Internet. Your Provider provides you with access
to an SMTP server.
69
Glossary
Subnet
A subnet divides a network into smaller units.
Subnet mask
The subnet mask determines how many parts of the IP addresses of a network represent the network number and how many parts represent the network component
number.
If the subnet mask in a network is 255.255.255.0, for example, this means that the first
three parts of the IP address make up the network number and only the last part can
be used to assign network component numbers. The first three parts of the IP address
of all network components are in this case always the same.
Switch
A switch is a central distributor in a wired network, which, unlike a hub, provides intelligent distribution of data transfer. The switch only ever forwards a data packet to the
subnet or network component the data packet is intended for. Unnecessary transfer of
data in the network thus avoided.
TAE
Telecommunications connecting unit (German: Telekommunikations-Anschlusseinheit). Connector for connecting analogue telecommunications devices. F for phone, N
for additional devices such as fax or answer machines.
TCP
Transmission Control Protocol. TCP is part of the TCP/IP protocol family. TCP handles
data transport between communication partners (applications). TCP is a sessionbased transmission protocol, i.e. it sets up, monitors and terminates a connection for
transporting data.
TCP/IP
Transmission Control Protocol/Internet Protocol. Protocol family on which the Internet
is based. IP forms the basis of each PC to PC 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. In order to access the Internet from a PC, TCP/IP must be set up on the
PC.
UDP
User Datagram Protocol. UDP is a Protocol of the TCP/IP protocol family that handles
data transport between two communication partners (applications). Unlike TCP, UDP
is a non-session based protocol. It does not establish a fixed connection. The recipient
is responsible for making sure the data is received. The sender is not notified about
whether it is received or not.
Uplink
Data that your SE681 WiMAX forwards from your PC or local network to external sites
(e.g. to the Internet).
70
Glossary
URL
Universal Resource Locator. Globally unique address of a domain on the Internet, e.g.
http://www.sagemcom.com.
Virtual server
A virtual Server provides a service on the Internet that runs not on itself, but on another
network component. The SE681 WiMAX 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.
WAN
Wide Area Network. A WAN is a network that is not restricted to one particular area,
such as the Internet. A WAN is run by one or more public providers to enable private
access. You access the Internet via a Provider.
WiMAX
Worldwide Interoperability for Microwave Access. WiMAX is a modern wireless network technology that enables fast Internet connection even in remote areas where no
other connection possibility (e. g. DSL) is available.
