Encryption and ID verification ensure that the automatic con-

figuration of the FRITZ!Box can not be intercepted or per-

formed by unauthorized parties.

Automatic configuration of the FRITZ!Box is possible only if

the Internet Service Provider supports remote configuration

with TR-069. Which data are transferred to the FRITZ!Box and

how remote configuration is started depends on the provider.

For some providers, for instance, the user must enter a start

code in the FRITZ!Box user interface.

UMTS

short for Universal Mobile Telecommunications System

UMTS is a third-generation (3G) mobile radio standard with

throughput rates of 384 Kbit/s to 7.2 Mbit/s.

The high throughput rates make it possible to support multi-

media services. With special cards or USB sticks the Internet

connection can also be provided for laptops or computers via

UMTS.

update

A more recent version of software or firmware is called an up-

date. Updates are often free of charge, resolve minor pro-

gramming errors, and sometimes also offer new functions.

uplink port

The uplink port on a hub or switch is designed for connecting

another hub or switch, or a router. In contrast to the uplink

port, there is also a user port for connecting terminal devices.

The send and receive directions are transposed on the uplink

port. On some devices the port can change between normal

and uplink mode by means of a switch.

upload

This term designates the procedure of transmitting files from

one’s own computer to another computer in the Internet.

UPnP

short 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 ser-

vices—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 (

see glossary

), with or without cen-

tral 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 au-

tomatically using UPnP to exchange information.

Today the UPnP forum specifies the UPnP standard and certi-

fies devices that are compliant with this standard.

UPnP AV

short for Universal Plug and Play Audio/Video

UPnP AV is a UPnP specification for the interaction between

the media server, playback devices and devices controlling

the streaming (transmitting a data stream) of audio, image

and video data within networks. Media servers are devices

that make audio, image and video data available upon re-

quest. Playback devices render the audio, image and video

data (televisions, stereo systems, streaming clients). Control

devices are remote controls (smartphone, remote control).

USB

short for Universal Serial Bus

The Universal Serial Bus is an interface for transferring data

between a computer and connected devices. It was intro-

duced in 1996. Today nearly all computers have multiple USB

ports. USB is used, for instance, to connect many keyboards,

mice, printers and external hard drives to the computer.

By now many other devices also have a USB port. For in-

stance, many DVD and Blue-ray players can play back photo-

graphs, videos and music directly from a USB storage medi-

um (hard drive, flash drive).

The Universal Serial Bus supports hot plugging. This means

that USB devices can be connected without turning the com-

puter off. The Universal Serial Bus also offers a 5-volt power

supply. This makes it possible to load devices at the USB port

and operate USB devices that do not have a power supply of

their own.

The Universal Serial Bus was introduced with the USB 1.0

specification in 1996. In 1998 came the reworked USB 1.1

specification, followed in 2000 by USB 2.0. With 480 Mbit/s,

USB 2.0 provides for considerably higher throughput rates

than USB 1.0/1.1 (12 Mbit/s).

VDSL

short for Very High Speed Digital Subscriber Line

In Germany, the DSL technology VDSL is increasingly becom-

ing available in the VDSL2 (G993.2) version. VDSL2 is a fur-

ther development of the ADSL2+ standard, to which it is fully

downward compatible. The standard provides for throughput

rates of up to 100 Mbit/s for uploading and downloading, but

requires a distribution network with a more closely meshed

infrastructure—a demand that is hardly economical outside

of major urban areas.

VoIP

short for for Voice over IP, also known as Internet telephony

Calls from the Internet are possible to and from the fixed-line

network and mobile networks. Various Internet Service Pro-

viders and telephony carriers provide SIP-fixed-line gateways

for this purpose. The gateways are used to produce voice con-

nections between the Internet and conventional telephone

networks.

Glossary

In principle, VoIP calls can be made over any Internet connec-

tion. However, for convenient use with existing terminal de-

vices, and for conversations with the fixed-line and mobile

networks, it is important that the Internet Service Provider

support what is known as the SIP standard. SIP is the current

standard defined for VoIP by the IETF (Internet Engineering

Task Force).

VPN

short for Virtual Private Network

VPN serves to integrate 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 distrib-

uted 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 infra-

structure of the Internet.

Using a Virtual Private Network it is possible to use all net-

work 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 loca-

tions. E-mail servers, file sharing and other central applica-

tions of the company network can thus be made available via

VPN even to distant branch offices, subsidiaries and home of-

fices. With VPN, field representatives of a company can also

be granted secure access to the company network.

WLAN

short for Wireless Local Area Network

The term WLAN designates the industry standard for wireless

local networks passed by the Institute of Electrical and Elec-

tronics Engineers (IEEE) in 1997 under the title IEEE 802.11.

By means of WLAN technology, individual computers or net-

work devices like printers or DSL access points can be linked

wirelessly to an existing cable-connected local network (LAN),

or LANs can be converted completely to a wireless structure.

A further useful purpose for WLAN technology is to link seg-

ments of existing cable-connected networks.

Although WLAN was actually developed only for short-range

connections, by cascading WLAN base stations or implement-

ing transmission networks with high-power point-to-point ra-

dio transmission, even network segments located further

away from each other can be linked or network participants in

relatively remote locations can be economically and easily in-

tegrated into an existing network.

WLAN base stations often also serve as access points to the

Internet in private or public institutions. Many airports, hotels

and cafes, for instance, make WLAN hotspots available to

their customers, either free or subject to a charge. Ultimately

this has maneuvered WLAN into serious competition with mo-

bile UMTS technology.

The application possibilities for wireless network communi-

cation also overlap with Bluetooth technology. For mobile de-

vices with limited energy capacity Bluetooth is the more use-

ful solution, however, as Bluetooth uses considerably less

power than wireless LAN. What is more, Bluetooth technology

is more flexible and thus can offer a greater bandwidth of po-

tential applications.
