PPTP is a network protocol, which is used for an ADSL-access (specially in Austria).
DSL Modem:
The DSL modem, serves the transmission of data over a DSL-line.
Router:
A Router is a switching-computer, which is involved in establishing a connection in a computer network, e.g.
the internet. Such switching-computers route the data packages on the basis of the address to the
respective target computer. The address determines, to which other Router or personal computer the data
must be send to and the Router decides for each case (temporally and distance-moderately) the most
favourable way. You can also use a Router to function as a switching-computer between several local
networks (LANs) with a uniform protocol.
Splitter:
A splitter separates language traffic (e.g. a telephone) from the data traffic.
On the interface for data traffic an ADSL modem or routing can be plugged on.
GPRS:
„General Packet Radio Service“
The GPRS is a new non voice value added service based on the IP protocol that allows information to be
sent and received across a GSM mobile telephone network.
The conventional GSM network data transmission rates are a maximum of 9.6 Kbps (bit per second), with
GPRS theoretically far over 100 Kbps are possible. However so far the actually carried out values are approx.
40Kbps.
APN:
„Access Point Name“
An APN-access is comparable with a dial-in number,
which assigns the GPRS-connection a functionality, like a Internet-, network- or WAP-access
Initstring (AT-command)
AT-commands are instruction codes for intelligent modems
Intelligent modems can be configured or steered by AT-commands
ISDN:
„Integrated Services Digital Network“
An international communications standard for sending voice, video, and data over digital telephone
lines or normal telephone wires.
ISDN consists of two 64-Kbps B-channels and one D-channel for transmitting control information
S0 Bus (ISDN):
The S0 Bus is an international standard Bus with 4 wires behind the NTBA (Network Termination for Basic
24
Access) which is responsible for the connection of the ISDN terminal equipment.
On one S0-Bus it is possible to connect 8 terminals
B-Kanal (ISDN):
ISDN consists of two 64-Kbit/sec channels (called the B channels). Therewith two connections can get
established at the same time.
SIM (SIM card)
SIM cards are telephone cards for mobile phones. SIM cards identify the subscriber of the telephone
PIN:
„personal identification number“
The PIN is a secret number of a SIM-, credit- or Euro cheque card, which serves for the identification of the
card owner
WEP:
„Wired Equivalent Privacy“
Security protocol to encrypt radio waves in a wireless local area network. A WEP key-code is used for the
data encoding. The more highly the bit-rate of the key, the more highly the protection.
RAM:
„Random Access Memory“; working memory of the computers
The RAM is (in contrast to the hard disc drive) a non-permanent memory,
the data in the RAM will be stored as long as the current power supply is not interrupted.
UMTS:
Universal Mobile Telecommunications System (UMTS) is one of the third-generation (3G) cell phone
technologies.
To differentiate UMTS from competing network technologies, UMTS is sometimes marketed as 3GSM, em-
phasizing the combination of the 3G nature of the technology and the GSM standard which it was
designed to succeed.
WCDMA:
Wideband Code Division Multiple Access is a type of 3G cellular network. W-CDMA is the higher speed
transmission protocol used in the Japanese FOMA system and in the UMTS system, a third generation
follow-on to the 2G GSM networks deployed worldwide.
More technically, W-CDMA is a wideband spread-spectrum mobile air interface that utilizes the direct
sequence Code Division Multiple Access signalling method (or CDMA) to achieve higher speeds and
support more users compared to the implementation of time division multiplexing (TDMA) used by 2G GSM
networks.
