IP address
A unique address for a network compo-
nent within a network based on the
TCP/IP protocols (e.g. LAN, Internet).
On the Internet, domain names are
usually assigned instead of IP
addresses. DNS assigns the corre-
sponding IP address to the domain
name.
The IP address has four parts (decimal
numbers between 0 and 255) sepa-
rated by full stops (e.g. 230.94.233.2).
The IP address is made up of the net-
work number and the number of the
Network subscribers (e.g. phone).
Depending on the Subnet mask, the
front one, two or three parts make up
the network number and the rest of the
IP address addresses the network com-
ponent. The network number of all the
components in any one network must
be identical.
IP addresses can be assigned automati-
cally with DHCP (dynamic IP addresses)
or manually (static IP addresses).
See also: DHCP.
IP pool range
Range of IP addresses that the DHCP
server can use to assign dynamic IP
addresses.
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 network (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
private IP address.
See also IP address.
Local SIP Port
See SIP port/Local SIP port.
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 6
parts (hexadecimal numbers) sepa-
rated by a "-" (e.g. 00-90-65-44-00-3A).
The MAC address is assigned by the
manufacturer and cannot be changed.
Mbps
Million bits per second
Unit of the transmission speed in a net-
work.
MRU
Maximum Receive Unit
Defines the maximum user data vol-
ume within a data packet.
MTU
Maximum Transmission Unit
Defines the maximum length of a data
packet that can be carried over the net-
work at a time.
Music on hold
Music on hold
Music that is played while you are on a
Consultation call or Toggling. The
waiting participant hears music while
on hold.
N
NAT
Network Address Translation
Method for converting (private) IP
addresss to one or more (public) IP
addresses. NAT enables the IP
addresses of Network subscriberss
(e.g. VoIP telephones) in a LAN to be
concealed behind a shared IP address
for the Router on the Internet.
VoIP telephones behind a NAT router
cannot be reached by VoIP servers (on
account of the private IP address). In
order to "get around" NAT, it is possible
