Mbps
Acronym for megabit per second, a unit of measurement
that states the capacity (and thus the speed) of data
transmission along a computer network.
Modem
Modulator/demodulator. It is a device that modulates digital
data in order to permit its transmission along analogue
circuits, usually made up of telephone lines.
MNO
Acronym for Mobile Network Operator, an operator of
proprietary telecommunications on a mobile network that
offers its own services wholesale to all MVNOs (Mobile
Virtual Network Operator).
MPF
Acronym for Metallic Path Facility, the pair of copper wires
(unscreened twisted pair) that comes from an exchange
(MDF -Main Distribution Frame) in an operator’s telephone
room and arrives at the user’s premises (individual or
corporate). Connections can be Full or Shared. A Full type
connection enables the use of the data service (broadband)
in addition to voice traffic. A Shared kind of connection only
enables the use of the data service (broadband). In a
“shared access” service, the LLU operator (in ungrouped
access) provides the ADSL services to the end user, whilst
the incumbent operator provides the analogue telephony
service using the same access line.
MSAN
Acronym for Multi-Service Access Node, a platform able to
carry a combination of traditional services on an IP network
and that supports a variety of access technologies such as
for example a traditional telephone line (POTS), and
ADSL2+ line, a symmetric SHDSL line, VDSL and VDSL2
over a copper or fibre-optic network.
MVNO
Acronym for Mobile Virtual Network Operators: A party that
offers mobile telecommunications services to the public,
using its own mobile network interconnection structures, its
own HLR, its own mobile phone network code MNC, Mobile
Network Code), its own customer handling (marketing,
invoicing and support) and issuing its own SIM cards, but
does not have assigned frequencies and takes advantage,
for access, of agreements negotiated or regulated via one
or more licensed mobile network operators.
Narrowband
System for connecting to data networks, for example the
Internet, by means of a telephone call. In this kind of
connection all the bandwidth used for the means of
transmission is used as a single channel. One single signal
occupies all the available bandwidth. The bandwidth of a
communications channel identifies the maximum quantity
of data that can be carried by means of transmission of the
unit over time. The capacity of a communication channel is
limited by the frequency interval that the equipment can
sustain and by the distance to be travelled. An example of
a Narrowband connection is the common modem
narrowband connection at 56 kbps.
