An Overview
The FRITZ!Box connects your computers directly with your DSL line.
Each connected computer can establish an Internet connection over the
FRITZ!Box.
The FRITZ!Box is a Private Branch Exchange (PBX) for making telephone
calls via the Internet and the fixed-line network.
The FRITZ!Box connects your analog telephone and your computer with
the Internet. The FRITZ!Box can be connected directly via the DSL line or
using an already existing Internet connection. With the analog telephone you can make telephone calls via the Internet and the analog
fixed-line network. The Internet connection is available for all connected computers.

Call Waiting
Call waiting can be switched on or off for each extension.
Some older terminal devices connected to extensions may
misinterpret the call waiting signal. This is especially true
of fax machines and modems. If communication errors occur, you should disable call waiting for fax and modem extensions.
See section “Waiting Calls” on page 42 for information
about how to accept a call while another connection is active.
When call waiting is enabled, modem and fax connections may be interrupted.

Caller ID Suppression for Outgoing Calls (CLIR)
The CLIR (Calling Line Identification Restriction) function
prevents your telephone number being displayed on the
other party’s phone during outgoing calls.
The CLIR function is disabled in the factory settings. You
have the option of enabling this function permanently and
then disabling it again. CLIR can also be used for individual connections. When CLIR is permanently enabled, this
setting is saved for the extension and always enabled for
outgoing connections.
If you would like to conduct only certain calls with the Caller ID suppressed, prefix the number dialed with a keypad
sequence. This enables CLIR only for the current connection.

Disabling Automatic Outside Dialing
Disabling Automatic Outside Dialing
The FRITZ!Box offers the possibility of disabling automatic
outside dialing. This means that you will hear an internal
dialing tone when you lift the handset at the corresponding extension. This makes sense at any extension which
is used to make many internal calls, for instance, between
the extensions of the FRITZ!Box. When automatic outside
dialing is disabled, for an external call the 0 must be dialed before the telephone number.

7.4Operation at the Telephone
This section describes how you can use the FRITZ!Box features via your telephone keypad.
Shortening the Dialing Procedure
The FRITZ!Box automatically recognizes when a number
has been entered, but not until a few seconds after the final digits are entered.
You have the possibility of shortening the dialing procedure by closing your entry with the r key.
Shortening the Dialing Procedure

Define the Outgoing Number and the Type of Connection
For outgoing connections you can specify the kind of connection to be used for the next dialing procedure. For this
entry you can use settings already made, or circumvent
the settings currently configured. In this case the dialing
rules are suspended for the given dialing procedure.
By entering precisely which Internet telephony account
should be used it is possible to have the dialing procedure conducted via a certain Internet telephone number,
even though this number was never previously configured
for the extension used.

Checking the Security Software
Checking the Security Software
The user interface cannot be displayed in the web
browser.
Possible Cause
Security software is blocking access to the user interface.
Remedy
Security software like firewalls can prevent access to the
user interface of the FRITZ!Box. Configure exceptions for
the FRITZ!Box in all of the enabled security software.
If you would like to exit security software to test access to
the FRITZ!Box, remove the DSL cable first! After testing,
first start the security software before reinserting the DSL
cable and connecting to the Internet!
Opening the User Interface of the FRITZ!Box
The FRITZ!Box is equipped with a fixed IP address that
cannot be changed. FRITZ!Box always can be reached at
this IP address. This fixed IP address is:
Fixed IP address169.254.1.1
Proceed as follows to open the FRITZ!Box user interface
using this IP address:
1.Connect the FRITZ!Box to the computer using the net-
work cable (yellow). See the section “Connecting
Computers to the LAN Port” from page 16 for more information.
2.Make sure that the computer obtains its IP address
automatically. You can check this setting in the computer’s IP settings (see section “Obtaining an IP
Address Automatically” from page 57).
3.Restart your computer.
FRITZ!Box Fon 511356

Once you have reached the FRITZ!Box user interface
again, you should check the FRITZ!Box settings and correct them if necessary.
8.2Obtaining an IP Address Automatically
The FRITZ!Box is equipped with its own DHCP server. This
means that the connected computers obtain their IP addresses from the FRITZ!Box. The connected computers
must be configured such that they can receive their IP addresses automatically. The steps for checking and adjusting this option differ among the operating systems. See
the relevant section for your operating system.
If FRITZ!Box is operated in a network, no other DHCP server may be activated in this network.

See the information in the following section on the individual cables and adapters on the FRITZ!Box Fon 5113.
DSL/Telephone Cable
The DSL/telephone cable is a special combined cable developed by AVM to connect the FRITZ!Box Fon 5113 to the
DSL splitter and the ISDN NT or analog telephone line.
If you need a longer cable, you can extend one or multiple
ends of the combined cable using RJ45 double couplings.
Which ends of the cable you extend depends on the spatial conditions at your location.
You will need the following components to extend the
length of one or more ends of your DSL/telephone cable:
1 standard network cable
1 standard RJ45 CAT5 double coupling
Both components are available from specialized vendors.
AVM recommends a final length of no more than
10 meters.
Remember that the quality of the line may be decrease as
the distance from the central switching station increases.

For a description of the exact contents of your FRITZ!Box
package, see the cardboard box in which the FRITZ!Box
was delivered.
The DSL cable serves to connect the FRITZ!Box to a DSL
line without a telephone line.
You will need the following components to extend the
length of the DSL cable on the end with the RJ45 connector:
1 standard network cable
1 standard RJ45 CAT5 double coupling
All components are available from specialized vendors.
Remember that the quality of the line may be decrease as
the distance from the central switching station increases.
AVM recommends that cable be extended with a standard
network cable to a length of no more than 20 meters.
Network Cable
Additional network cable is required if you would like to
use all of the FRITZ!Box Fon 5113 network ports.
The FRITZ!Box Fon 5113 network cable (yellow) is a standard Ethernet cable. If you need a replacement cable, a
longer cable or an extension, use a standard STP-type
(Shielded Twisted Pair, 1:1) CAT5 Ethernet cable. To extend the cable you will also need a standard CAT5 double
coupling link to RJ45. You can use either straight cable or
cross-link cable. All components are available from specialized vendors.

More about Networks
2More about Networks
The FRITZ!Box is delivered with preconfigured network settings. According to these settings, all network devices connected with the FRITZ!Box
are located in a single network.
The network settings can be changed and adapted to your conditions
and needs. But you should do so only if you are well versed in networking technology.
The Glossary explains concepts and terminology having to do with
IP networks.
The section “Network Overview” from page 69 introduces the net-
work overview of the FRITZ!Box.
The sections “IP Address” from page 72, “DHCP Server” from
page 73 and “Subnetwork” from page 74 explain when it may
make sense to change the preconfigured network settings, what
the effects of these changes are, and how to make the changes.
2.1Network Overview
The FRITZ!Box user interface shows an overview with all of
the devices and users connected with the FRITZ!Box.
The “Devices and Users” network overview is found in the
following two menus: “Start Menu / Network” or “Settings
/ Advanced Settings / System / Network”.

Start Computer: Wake on LAN
Start Computer: Wake on LAN
The properties page for network devices that are connected with the FRITZ!Box via a network (LAN) port includes
the “Start Computer” button. Use this button to start computers that support Wake on LAN.
With the Wake on LAN function you can start computers in
your FRITZ!Box via the Internet. For instance, you can access a computer at any time using remote maintenance
software, without wasting electricity by keeping the computer switched on permanently.
2.2IP Settings
The IP settings of the FRITZ!Box are preset upon delivery
with the following values:
Factory Settings
All computers are located in the
same IP network
IP address192.168.178.1

UPnP Settings
2.3UPnP Settings
The Universal Plug-and-Play (UPnP) service included in
your FRITZ!Box provides status information about the
FRITZ!Box to all connected computers. Programs with
UPnP support on these computers can receive this information and use them to display the status of the
FRITZ!Box (e.g., DSL synchronization, connection status,
data transmission). UPnP service thus allows you to monitor your FRITZ!Box from a connected computer.
2.4IP Address
Upon delivery the FRITZ!Box is assigned the following IP
address:
192.168.178.1
If you would like to change the IP address, please read
through the following sections. Also note the additional
information in the section “Reserved IP Addresses” on
page 72.
When Does It Make Sense to Change the IP Address?
You should change the IP address of the FRITZ!Box if the
following applies to your network:
You have an existing local IP network, one subnet wi-
th several computers.
Fixed IP addresses are registered in the network set-
tings of the computer, and you do not want to or are
not permitted to change these addresses.
You want to connect the FRITZ!Box to the subnet in
order to make the FRITZ!Box features available to all
of the computers in the subnet.
Reserved IP Addresses
The entire IP network 192.168.180.0 in the FRITZ!Box is
reserved for internal purposes.
IP addresses from this network may not be assigned to the
FRITZ!Box.
FRITZ!Box Fon 511372
Page 73
DHCP Server
2.5DHCP Server
The FRITZ!Box is equipped with its own DHCP server. The
DHCP server is enabled by default in the factory settings.
The following range of IP addresses is reserved for the
DHCP server in the factory settings:
192.168.178.20 - 192.168.178.200
This IP address can be changed as needed.
Every time the operating system on a computer connected
with FRITZ!Box is started, the DHCP server assigns it an IP
address from the IP address range of the DHCP server.
Only one DHCP server may be active within any network.
Assigning the IP addresses via the DHCP server ensures
that all of the computers connected with the FRITZ!Box are
located in a single subnet.
The computers can receive their IP addresses from the
DHCP server only if the setting “Obtain an IP address automatically” is enabled in the their IP settings. For more
information, see the section “Obtaining an IP Address Automatically” from page 57.
Fixed IP Addresses when the DHCP Server Is Enabled
If you would like to configure fixed IP addresses on individual computers connected with the FRITZ!Box despite
the enabled DHCP server, please note the following:
The IP addresses must be from the IP network of the
FRITZ!Box.
The IP addresses may not come from the address
range of the DHCP server.
Each IP address can be assigned only once.
FRITZ!Box Fon 511373
Page 74
Disabling the DHCP Server
Disabling the DHCP Server
You can disable the DHCP server.
To make sure that all computers remain in the same IP network as the FRITZ!Box, you must enter the IP addresses
manually in the computers’ network settings. First disable
the option “Obtain an IP address automatically” and then
enter the IP address manually in the appropriate field.
In the case of the preset IP address of the FRITZ!Box, the
following IP addresses are available for assignment to the
computers:
192.168.178.2 - 192.168.178.253
Each IP address can be assigned only once.
2.6Subnetwork
By default the option “All computers are located in the
same IP network” is enabled in the FRITZ!Box.
If the factory settings were not changed, this setting has
the following effect:
The DHCP server of the FRITZ!Box assigns all of the computers connected with the FRITZ!Box an IP address from
the address range of the DHCP server.
This means that all of the computers connected with the
FRITZ!Box are located in the same IP network.
Disabling “All computers are located in the same IP
network”
If you switch off the setting “All computers are located in
the same IP network”, the interfaces of the FRITZ!Box will
receive their own IP addresses.
Factory SettingsUpon delivery the interfaces of the FRITZ!Box are config-
ured as follows:

More about Internet Telephony
3More about Internet Telephony
Voice over IP (VoIP)
Internet telephony has already been in use for years, but
today it allows even private customers the convenience familiar from conventional telephony, usually at significantly lower prices.
Internet telephony has also made it considerably more
convenient to use applications like conference calls and
answering machines in networks. Further advantages
include global availability at a single telephone number,
and the development of new standards for security and
voice quality.
Data TransferAll kinds of data transmission in the Internet use the Inter-
net Protocol (IP). IP is packet-oriented. This means that
the data are broken down into data packets for transmission and IP takes care of the transport of the individual data packets through the Internet. Language is also transmitted in the Internet in this manner.
In opposition to this, fixed-line telephony transmits data
in a line-oriented manner. In this case data are transmitted in a coherent data stream.
3.1Telephony Scenarios
If you have configured both a fixed-line number and an Internet telephone number in FRITZ!Box, you can make calls
in all directions:
from the fixed-line network into the fixed-line net-
work
from the Internet into the fixed-line network
from the Internet into the Internet
and receive calls from all directions as well.

ADSLabbreviation for Asymmetric Digital Subscriber Line
Designates a fast kind of file transfer that works with standard copper cables and transports signals in both directions at different speeds (upstream at 640 Kbit/s and
downstream at up to 9 Mbit/s).
ADSL2abbreviation for Asymmetric Digital Subscriber Line 2
ADSL 2 (G.992.3) is a further development of the ADSL
norm G.992.1/G.992.2).
ADSL2 offers range much greater than did the first ADSL
generation, and is significantly more robust than ADSL, as
it can simply disable single carrier frequencies when they
produce interference. This feature allows ADSL2 to prevent synchronization losses.
With a throughput rate of up to 12Mbit/s downstream,
ADSL2 offers considerably greater bandwidth than ADSL.
ADSL2 is completely downward compatible, meaning that
terminal equipment compliant with ADSL can also be operated on ADSL2 lines, although they cannot exploit the
advantages of ADSL2.
ADSL2+abbreviation for extended bandwidth Asymmetric Digital
Subscriber Line 2
ADSL2+ (G.992.5) is a further development of the ADSL
norm (G.992.1/ G.992.2).
ADSL2+ offers a doubled frequency range used for downstream transmission, and thus double the maximum
bandwidth achievable for downstream to 24 Mbit/s.
ADSL2+ is completely downward compatible, meaning
that terminal equipment compliant with ADSL and ADSL2
can also be operated on ADSL2+ lines, although they cannot exploit the advantages of ADSL2+.

AliasAlias means different, else and also known as. An alias is
often a short, catchy substitute for a long, complicated
string of characters, for example, the actual name of the
user J.Smith@my-internetprovider.com in place of the
string 030123456@my-internetprovider.com. Here the

DHCPabbreviation for Dynamic Host Configuration Protocol
DHCP is a protocol for the dynamic negotiation of the operating parameters for the TCP/IP protocol (TCP is a transport protocol based on the Internet protocol).
The computers of a local IP network (DHCP clients) access
the DHCP server as part of their operating systems’ start
procedure.
The central administration of the TCP/IP operation parameters makes it possible to avoid address conflicts caused
by IP addresses accidentally assigned more than once.
DHCP ServerThe DHCP server assigns each client an IP address that is
has not yet been assigned at the present time. The DHCP
server also informs the client of the IP addresses of the

DNS server to be used and of the default gateway. In assigning the IP addresses the DHCP server selects from a
prescribed pool of IP addresses.
DNSabbreviation for Domain Name System
Domain Name Service takes care of determining the IP address for a given domain name, Domain Name Service is
running on every computer. It accepts the domain name
entered by a user and inquires about the corresponding IP
address at a DNS server known to the service. If a DNS
server cannot answer the inquiry itself, it can inquire
about the IP address (DNS resolution) at other DNS servers.
If the Domain Name Service receives negative information
from the DNS server (domain name not known), it can
send inquiries to other DNS servers it knows or return a
corresponding error message to the user. If it receives the
desired IP address instead, the application can use the IP
address to retrieve the destination desired by the user.
This hierarchical system of DNS servers is known as the
Domain Name System. The addresses of the DNS servers
at which the Domain Name Service is to inquire by default
generally are handed over to the computer by the Internet
Service Provider automatically whenever a connection to
the Internet is established. In local networks addresses
can also be assigned via DHCP. Otherwise they must be
entered manually in the TCP/IP settings of the PC by the
user or the system administrator.
DSL ModemA DSL modem connects a computer to the Internet via the
DSL line. In contrast to the analog modem, a connection
via the DSL modem does not mean that the telephone line
is busy.
DSL RouterA combination of a DSL modem and a router is called a
DSL router.

Glossary
Dynamic DNSabbreviation for Dynamic Domain Name System
Dynamic DNS is a service which allows a computer always
to be reached under the same domain name despite constantly changing IP addresses. This means that even private users have an economical way of placing their own
Internet offers on their computer at home.
It works by transmitting the current IP address to a special
DDNS server each time the IP address changes. Except for
the few seconds between the cancellation of the old IP address and the notification of the new IP address, the computer can always be reached at the selected domain
name.
Dynamic IP
Address
A dynamic IP address is an IP address valid only for the
duration of one Internet or network session.
Every computer participating in the Internet must have a
uniquely assigned public IP address. Since only a limited
number of such IP addresses is available, they must be
used sparingly. That is why most of the Internet participants who dial in to the Internet receive a dynamic IP address. They are called dynamic because every participant
receives a new public address that has not been assigned
yet each time she or he dials in to the Internet.
By contrast, dynamic addresses are usually used in local
IP networks because they are easy to handle, and because
using them avoids incorrect IP address entries or unintentional double assignments. The DHCP service is responsible for assigning unique dynamic IP addresses.
FAQabbreviation for Frequently Asked Questions
FAQs are collections with answers to frequently asked
questions on a certain subject area.
FirewallA firewall protects a computer or local network against at-
tacks from the Internet.
FRITZ!Box Fon 511384
Page 85
Glossary
Most firewalls work with packet filters, which merely
check the IP addresses and port numbers of incoming and
outgoing data packets and filter the packets according to
prescribed rules.
Some firewalls also integrate additional concepts like IP
masquerading and NAT to decouple data traffic by distinguishing strictly between the internal and external network.
Especially effective firewalls go even further, analyzing
and evaluating the contents of the packets and filtering
them according to prescribed rules. Such techniques may
also include a Stateful Packet Inspection Firewall, for instance.
FirmwareThe firmware is saved in programmable components with-
in a device. Through the possibility of updating the firmware by computer at any time, manufacturers enjoy great
flexibility in reacting to the demands of the operational
environment, integrating new functions requested by customers, and eliminating errors discovered after production.
Fixed IP AddressFixed IP addresses are IP addresses which are permanent-
ly assigned to a computer or another device like a network
printer.
Assigning fixed IP addresses makes sense in cases where
a local network has a sufficiently large pool of IP addresses available, or when a computer is always supposed to
be accessible at a certain address (such as a web server or
e-mail server).
FTPabbreviation for File Transfer Protocol
The File Transfer Protocol allows files to be exchanged between two computers operating in the Internet. Data exchange takes place via an FTP server and what is known as
an FTP client. The more convenient FTP clients are available as stand-alone software or are components of some
ISDN data transfer software; simple FTP clients are now included in many web browsers.

GatewayGateway is a general term designating an interface be-
tween two computer networks. Such a network interface
can be realized using a router or a bridge, for instance.
If a computer wants to transfer data packets to a computer
in another network, it must first transmit the packet to the
gateway. To do this, the computer must know the address
of the gateway.
If all packets that cannot be delivered in a local network
always are to be transmitted to their given recipients via
the same gateway, for this purpose the address of the
gateway must be saved as the default gateway in the network settings of the computer.
Such a default gateway for the computer is negotiated automatically by the operating system or the dialing software whenever an ISDN-Controller or DSL-Controller establishes a connection to the Internet. If a router is used for
the shared Internet access in a local network, the IP address of the router must be entered as the default gateway
in the TCP/IP settings of each computer that wishes to use
the Internet connection. If the TCP/IP setting is configured
by means of a DHCP server, there is no need to enter the
gateway address manually.
IPabbreviation for Internet Protocol
The IP Internet Protocol is the most important basic protocol for the control of data exchange in local networks and
in the Internet. The Internet protocol works without a connection; in other words, data packets are transmitted from
the sender to the recipient without previous consultation.
The addresses of the recipient and the sender in the data
packets are given as IP addresses.

IP Addressabbreviation for Internet Protocol address
In IP-based networks, for instance in the Internet and local
networks, all connected devices are addressed via their IP
addresses. So that data packets are sure to be delivered
to the right address, each IP address may be assigned only once within the Internet or a local IP network.
The IP address consists of four three-digit groups of numbers (for instance, 192.168.178.247). Each group of numbers can assume values between 000 and 255.
Every IP address contains two components: the network
address and the host address. These two components can
be read out of an IP address only if the subnet mask is also specified.
IP addresses can be public or private, and also fixed or assigned dynamically. See the corresponding entries in the
glossary for more information.
IP AddressingAddressing is one of the main functions of the Internet
Protocol (IP). Internet addresses can be written in decimal, octal or hexadecimal notation. The FRITZ!Box uses
“dotted-decimal” notation: The four bytes of an address
are represented by decimal numbers separated by dots.
The full set of IP addresses, called the address space, is
grouped into address classes designated as A, B, C, D and
E. Only the first three of these five address classes are actually used. These classes can be described as follows:
ClassesPropertiesNetwork Address,
Class A addressFew networks, many hubs 0-127

Properties of IP Address Classes
Every IP address consists of two parts: the network address and the host address. The sizes of the network address and the host address are variable, and determined
by the first four bits (of the first byte) of the IP address.

By means of IP masquerading a computer or LAN can be

protected from unauthorized connection request from the
Internet. Masquerading works by converting the IP addresses used in a network to one public IP address. From
the outside it appears that all requests are sent from a single computer.
IP NetworkA network in which data exchange takes place on the ba-
sis of the Internet Protocol is called an IP network.

used by multiple applications to exchange data with remote sites at the same time, a computer administers what
are known as ports for the IP-based protocols TCP and
UDP. Ports substantiate the point of access for the data
packets delivered via the IP Internet protocol. While the IP
address determines the destination computer quite generally, the port addresses the communication interface
provided by an application for a certain communication
procedure.
The Internet protocol allots 16 bits for the specification of
the port number. Thus a total of 65,535 different port
numbers can be specified. Ports up to port number 1,024
are reserved for special system applications and typical
Internet applications. These include, for instance, the port
numbers 21 for FTP (File Transfer Protocol), 25 for SMTP
(Simple Mail Transfer Protocol), 53 for DNS (Domain Name
Service) and 80 for HTTP (Hypertext Transfer Protocol).
Ports are primarily of interest to users for their role in protecting an Internet connection from external attacks. Most
firewalls offer the possibility of preventing data traffic on
FRITZ!Box Fon 511388

Glossary
certain ports. This means that certain port numbers can
be blocked to prevent data from being delivered to system
services. This is also a way of preventing any Trojans (malicious aplications opening backdoors on a computer) that
may have infected your computer from receiving data on
ports it created as means of accessing your computer for
potentially damaging activities. A firewall blocks most
atypical port numbers not required for normal operation of
an application and offers specialized users the opportunity to forward specified ports.
Port ForwardingWith port forwarding it is possible to specify ports that will
allow all incoming or outgoing data packets to pass
through a router or firewall.
If a computer from the local network offers server services,
for instance, the settings of a router using NAT or IP masquerading must enable or forward the port used by the
server service for access to incoming data packets and
thus keep it open permanently. The private IP address of
the given PC must be saved as the destination address for
all of the packets arriving at the port.
Typical server applications which require port forwarding
are FTP and Web servers. To allow access to a computer via
remote management software like Symantec’s pcAnywhere or Microsoft’s Remote Desktop, or even use of a
file-sharing program like eDonkey, the required ports must
be released for port forwarding. Port forwarding settings
for the most important application cases are quite simple
as long as the settings of the router or the firewall already
contain rules with a corresponding preconfiguration.
Private
IP Address
Private IP addresses are used for computers and other
network devices within local IP networks.
Since many local IP networks are not connected to the Internet except via single computers or routers (gateway),
certain address ranges are excluded from the publicly
available IP addresses so that they are available for assignment in local IP networks. An IP address may only be
assigned once within the local network. A private IP address may exist in any number of other local networks.

Public
IP Address
A public IP address is an IP address valid in the Internet.
Every computer or router participating in the Internet must
have a uniquely assigned public IP address. This address
is usually negotiated dynamically with the Internet Service
Provider when a connection to the Internet is dialed. The
Internet Service Provider assigns the negotiated IP address to the computer or router for the duration of an Internet session.
SubnetworkA local IP network can consist of one subnetwork or be di-
vided into multiple subnetworks. The division into subnetworks is performed when the local IP network is configured. The subnetworks of a local IP network are also IP
networks.
Subnet MaskThe subnet mask indicates which part of an IP address is
the network address and which the address of the computer. The network address defines what is called the subnet.
Example 1
IP address:192.168.178.247
Subnet mask:255.255.255.0
The assignment of the first three groups of numerals in the subnet mask indicates that the first three groups of numerals in the
IP address define the network. The following addresses result:
Network address of the subnet: 192.168.178.0
Address of the computer in the
subnet:
IP address pool in the subnet:192.168.178.0 -
192.168.178.247
192.168.178.255
The IP addresses
192.168.178.0 and
192.168.178.255 are reserved. This means that the addresses from 192.168.178.1
to 192.168.178.254 are
available for assignment to the
computers. Therefore a maximum of 254 computers can be
included in the subnetwork.

Example 2
IP address:192.168.178.247
Subnet mask:255.255.0.0
The assignment of the first two groups of numerals in the subnet mask indicates that the first two groups of numerals in the
IP address define the network. The following addresses result:
Network address of the subnet: 192.168.0.0
Address of the computer in the
subnet:
IP address pool in the subnet:192.168.0.0 -
192.168.178.247
192.168.255.255
That’s 65,536 IP addresses.
The IP addresses 192.168.0.0
and 192.168.255.255 are reserved. This means that the
addresses from 192.168.0.1 to
192.168.255.254 are available for assignment to the computers.
TCP/IPabbreviation for Transmission Control Protocol / Internet
Protocol
TCP/IP is the “language” of the Internet. TCP/IP is used to
refer to a suite of protocols used for data communication
over the Internet. TCP and IP are the network and transport
protocols underlying most Internet services, including file
transfer (FTP) and e-mail communication (SMTP). TCP/IP is
available for practically all computer systems. TCP/IP thus
offers the advantage of trouble-free communication between otherwise incompatible networks and systems.
TR-069T-069 is an HTTP-based protocol for communication be-
tween CPE (Customer Premises Equipment) and an Auto
Configuration Server (ACS) belonging to the Internet Service Provider. The TR-069 protocol is also known under the
alternative name CPE WAN Management Protocol (CWMP).
It offers the possibility of setting up the terminal device
FRITZ!Box Fon 511391
Page 92
Glossary
securely and automatically and thus, most importantly, facilitates simple initial configuration of the ADSL terminal
equipment by the end customer.
The TR-069 protocol can be used for automatic configuration only if it is actively supported by the given terminal
device. For this an Auto Configuration Client (ACC) must be
integrated in the device. The specifications for automatic
configuration of the ADSL terminal device are stored on
the Auto Configuration Server by the given Internet Service
Provider. The process of automatic configuration via TR069 is initiated by the ADSL terminal device. First the user
enters a security key and then the settings are retrieved
from the Auto Configuration Server and implemented in
the ADSL terminal device without any further interaction
with the user. During this process all of the communication between the ADSL terminal device and the Auto Configuration Server takes place in encrypted form.
Traffic ShapingTraffic shaping is a technology for the optimization of ca-
pacity loads in a communication connection. Especially
for asymmetrical DSL connections, using traffic shaping
can prevent that a download is delayed or blocked by high
upload traffic.
Data transfer in the Internet is generally based on the
TCP/IP protocol, which waits for the remote site to confirm
reception after sending one or more data packets. Additional data packets are not sent until this confirmation of
reception arrives. If no confirmation arrives over a longer
period of time, the non-confirmed data packets are transmitted again. The dispatch of such a confirmation can be
delayed, for instance, because the bandwidth for transfer
(upload) is already being used by the data packets of
other applications. But since the remote site does not signal the reception of the expected confirmation packets until after they have arrived, this could cause noticeable delays in rendering a requested web site or a drop in the
throughput rate of a download. In the worst-case scenario,
the remote site will abort transmission after several apparently unsuccessful attempts to transfer of the data packets. Typical causes for such a blockade situation include
FRITZ!Box Fon 511392
Page 93
Glossary
sending an e-mail message or the use of a program for private data exchange (also known as file sharing or peer-topeer software).
Through traffic shaping these delays are avoided by providing the dispatch of confirmation packets with bandwidth suitable for the given download activities. All of the
packets to be sent are also assigned a priority suitable for
their packet types.
UpdateA more recent version of software or firmware is called an
update. Updates are often free of charge, resolve minor
programming errors, and sometimes also offer new functions.
UploadThis term designates the procedure of transmitting files
from one’s own computer to another computer in the Internet.
UPnPabbreviation for Universal Plug and Play (UPnP)
UPnP is an extension of the Microsoft Plug & Play standard
that allows devices to network globally and to exchange
services – without a central server or computer.
UPnP allows devices from all kinds of manufacturers (stereo systems, routers, printers, house controls) to be controlled via an IP-based network, with or without central
control through a gateway. It is based on a number of
standardized network protocols and data formats. Expressed simplistically, devices can communicate with
each other using UPnP to exchange information.
Today the UPnP forum specifies the UPnP standard and
certifies devices that are compliant with the standard.
VoIPabbreviation for Voice over IP, also known as Internet tele-
phony
Voice over IP makes telephone calls possible via the Internet. The technology has already been in use for years, but
today it allows even private customers the convenience familiar from conventional telephony, usually at significantly lower prices. VoIP has also made it considerably more
FRITZ!Box Fon 511393
Page 94
Glossary
convenient to use applications like conference calls and
answering machines in networks. Added to this are global
accessibility under a single telephone number and new
VoIP features like the Buddy List known from chat rooms.
Internet telephony used to be possible only with a headset connected to the computers of the callers and their
conversation partners. Today voice connections via the Internet, even to fixed-line and mobile networks, can be
conducted conveniently using VoIP telephone systems
that allow already existing analog telephones to be used
even when the computer is switched off. Various Internet
Service Providers and telephony carriers provide SIPfixed-line gateways for this purpose. Such a gateway is
used to produce voice connections between the Internet
and conventional telephone networks. In principle VoIP
conversations are possible via every DSL access point, but
for convenient use with existing terminal equipment, and
for conversations with the fixed-line and mobile networks,
it is important that the DSL provider supports what is
known as the SIP standard. SIP is the current standard defined for VoIP by the IETF (Internet Engineering Task Force).

VPNabbreviation for Virtual Private Network
VPN serves to integrates devices from a neighboring network into your own network, without the networks having
to be compatible with each other.
A VPN is generally an independent company network distributed over several locations, which uses the infrastructure of a public communications network to link its partial
networks or to link individual computers to the rest of the
network. A VPN uses tunneling technologies and typically
builds on the infrastructure of the Internet.
Using a Virtual Private Network it is possible to use all network applications of the company network even from distant locations. This means it is possible to use the advantages of the network even over large geographical distances.
VPN facilitates optimum information flow without delay
throughout the entire company, even to offices in other locations. E-mail servers, file sharing and other central applications of the company network can thus be made
available via VPN even to distant branch offices, subsidiaries and home offices. With VPN, field representatives of
a company can also be granted secure access to the company network.
