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 num-
bers) separated 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 network.
MRU
Maximum Receive Unit
Defines the maximum user data volume within a data packet.
MTU
Maximum Transmission Unit
Defines the maximum length of a data packet that can be carried over the network at a
time.
Music on hold
Music is played while you are making a
consultation call
or
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. With
NAT, the IP addresses of
network subscribers
(e.g., VoIP phones) in a
LAN
can be hidden
behind a joint IP address for the
router
in the
Internet
.
VoIP telephones behind a NAT router cannot be reached by VoIP servers (on account of the
private IP address). To "bypass" NAT it is possible to either use
ALG
in the router,
STUN
in
the VoIP telephone or an
outbound proxy
for the VoIP provider.
If an outbound proxy is made available you must allow for this in the VoIP settings for your
phone.
Network
Group of devices. Devices can be connected in either wired or wireless mode.
Networks can also differ in range and structure:
– 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.
