E
ECT (Explicit Call Transfer)
Subscriber A calls Subscriber B. He puts
the connection on hold and calls Sub-
scriber C. Rather than connect every-
one in a three-party conference, A now
transfers Subscriber B to C and hangs
up.
Encryption
Encryption protects data against unau-
thorised access.
Encryption within a WLAN only pro-
tects data exchange within the WLAN,
not data exchange with Ethernet net-
works or with the Internet.
Your handset supports encryption with
WEP, WPA and WPA-PSK.
For further security settings, see
Authentication.
Enquiry Call
You are making a call. Using an enquiry
call, you interrupt the conversation
briefly to establish a connection to
another subscriber. If you terminate the
connection to this subscriber immedi-
ately, then this was an enquiry call. If
you switch to and fro between the first
and second subscriber, it is called tog-
gling.
Ethernet Network
Wired LAN.
F
Firewall
You can use a firewall to protect your
network against unauthorised external
access. This involves combining various
measures and technologies (hard and/
or software) to control the flow of data
between a private network you wish to
protect and an unprotected network
(e.g. the Internet).
See also: NAT.
Firmware
Device software in which basic infor-
mation is stored for the functioning of
a device. A new version of the firmware
can be loaded into the device's memory
(firmware update) to correct errors or
update the device software.
Flat rate
System of billing for an Internet con-
nection. The Internet provider charges
a set monthly fee. There are no addi-
tional costs for the duration of the con-
nection or number of connections.
Fragmentation
Data packets that are too big are split
into smaller packets (fragments) before
they are transferred. They are put
together again when they reach the
recipient (defragmented). You can
specify a threshold for fragmentation
(fragmentation threshold). If data
packets are smaller than the threshold
value they may not be fragmented.
Full Duplex
Data transmission mode in which data
can be sent and received at the same
time.
G
Gateway
Connects two different networks with
one another, e.g. router as Internet
gateway.
For phone calls from VoIP to the tele-
phone network the gateway has to be
connected to the IP network and the
telephone network (gateway/SIP pro-
vider). It forwards calls from VoIP to the
telephone network as required.
