optionally also of wired parts. Several WLAN clients (terminals) can
log in to an access point (AP) and communicate via the AP data. If
the optional wired Ethernet is connected, the signals between the
two physical media, the wireless interface and wired interface, are
bridged (bridging).
Filters can be used to prevent external persons from accessing the
data on the computers in your LAN. These filters are a basic func-
tion of a firewall.
Recording of connection data, e.g. date, time, connection duration,
charging information and number of data packets transferred.
Active probing takes advantage of the fact that as standard, access
points are to respond to client requests. Clients therefore send
"probe requests" on all channels and wait for responses from an ac-
cess point in the vicinity. The response packet then contains the
SSID of the wireless LAN and information on whether WEP encryp-
tion is used.
An ad hoc network refers to a number of computers that form an in-
dependent 802.11 WLAN each with a wireless adapter. Ad hoc net-
works work independently without an access point on a peer-to-peer
basis. Ad hoc mode is also known as IBSS mode (Independent Ba-
sic Service Set) and makes sense for the smallest networks, e.g. if
two notebooks are to be linked to each other without an access
point.
Asymmetric digital subscriber line
Authentication header
Display unit e.g. for T-Concept PX722 system telephone, able to
display letters and other characters as well as digits.
For the connection of analogue terminals such as telephone, fax
and answering machine.
Terminals that transmit voice and other information analogously,
e.g. telephone, fax machine, answering machine and modem.
To transmit voice via the telephone, acoustic oscillations are conver-
ted to continuous electrical signals, which are transmitted via a net-
work of lines (digital voice transmission).
You configure an analogue answering machine under "Terminal
Type".
