E
ECT
Explicit Call Transfer
Participant A calls participant B. The participant puts the connection on hold and calls par-
ticipant C. Rather than connect everyone in a three-party conference, A now transfers par-
ticipant B to C and hangs up.
EEPROM
Electrically Erasable Programmable Read-Only Memory
Memory building block in your phone with fixed data (e.g., default and customised set-
tings) and data saved automatically (e.g., call list entries).
Encryption
Encryption protects confidential information against unauthorised access. With an encryption sys-
tem, data packets can be sent securely over a network.
Ethernet network
Wired LAN.
Ethernet uses a base band cable for data transmission with a transmission rate of 10 or 100
Mbps or 1 Gbps.
F
Firewall
You can use a firewall to protect your network against unauthorised external access. This
involves combining various measures and technologies (hardware and/or software) to
control the flow of data between a private network you wish to protect and an unpro-
tected network (e.g., the Internet).
See also: NAT.
Firmware
Device software in which basic information is saved for the functioning of a device. To cor-
rect errors or update the device software, a new version of the firmware can be loaded into
the device's memory (firmware update).
Fixed IP address
A fixed IP address is assigned to a network component manually during network configu-
ration. Unlike a dynamic IP address, a fixed IP address never changes.
Flat rate
System of billing for an Internet connection. The Internet service provider charges a set
monthly fee. There are no additional charges for the duration of the connection 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).
Full duplex
Data transmission is a mode in which data can be sent and received at the same time.
