L
LAN
Local Area Network
Network with a restricted physical range.
A LAN can be wireless (WLAN) and/or wired.
Local IP address
The local or private IP address is the address
for a network component in the local net-
work (LAN). The network operator can assign
any address he or she wants. Devices that act
as a link from a local network to the Internet
(gateway or router) have a public and a pri-
vate IP address.
See also IP address.
M
MAC address
Media Access Control address
Hardware address by means of which
each network device (e.g., network card,
switch, phone) can be uniquely identified
worldwide. It consists of six parts
(hexadecimal numbers) separated by "-"
(e.g., 00-90-65-44-00-3A).
The MAC address is assigned by the manu-
facturer and cannot be changed.
Mbps
Million bits per second
Unit of the transmission speed in a network.
Music on hold
Music that is played while you are on a
Consultation call or during Call swapping.
The waiting participant hears music while
on hold.
N
NAT
Network Address Translation
Method for converting (private) IP
addresses to one or more (public) IP
addresses. NAT enables the IP addresses of
Network subscribers (e.g., your telephone )
in a LAN concealed behind a shared IP
address for the Routers on the Internet.
Network
Group of devices. Devices can be connected
in either wired or wireless mode.
Networks can also differ in range and struc-
ture:
– Range: Local networks (LAN) or wide-
area networks (WAN)
– Structure: Infrastructure network or
ad-hoc network
Network subscriber
Devices and PCs that are connected to each
other in a network e.g., servers, PCs and
phones.
P
Paging (handset search)
Base function for locating the registered
handsets. The base establishes a connection
to every registered handset. The handsets
start to ring.
PIN
Personal Identification Number
Protects against unauthorised use. When
the PIN is activated, a number combination
has to be entered to access a protected area.
You can protect your base configuration
data with a system PIN (4-digit number com-
bination).
Port
Data is exchanged between two applica-
tions in a Network via a port.
Port forwarding
The Internet gateway (e.g., your router) for-
wards data packets from the Internet that
are directed to a certain Port to the port con-
cerned. This allows servers in the LAN to
offer services on the Internet without you
needing a public IP address.
