Glossary
Terminology
J
IPv6 Address
In order to ensure that the data packets reach the correct recipients, all of the devices in a TCP/
IP network require a unique address, known as the IP address. IPv4 addresses comprise eight
blocks with four digits or characters each that are separated by a colon, for example,
3001:00FF:ABC0:0EAC:0001:0000:0000:000F, or, abbreviated, 3001:FF:ABC0:EAC:1::F.
Thanks to the greater length of IPv6 addresses, IPv6 offers a greater number of available IP
addresses than version 4 of the Internet protocol (IPv4).
J
Jitter Buffer
The jitter buffer buffers RTP packages, to compensate irregular transfer rates of the Internet.
A high jitter buffer reduces short interruptions during the call. In return the delay of the RTP
packages increases.
L
LAN
The LAN (Local Area Network) connects computers over company or home networks.
LED
An LED is a light emitting diode. This is an electronic device that is similar to a lamp and is used
for displays (also multi-coloured).
Loudspeaker Listening
During loudspeaker listening, the receiver loudspeaker as well as the loudspeaker in the device
are switched on. This allows other people in the room to listen in on the call. The call is
continued using the receiver microphone (no hands-free calling).
