Media Filter
A device used to convert Token-Ring adapter board output signal to function with
a particular type of wiring. Media Filters are required for 16 Mbps networks and
recommended for 4 Mbps networks using Type 3 (UTP) cable.
Metropolitan Area Network (MAN)
A network linking together LANs and other networks at many sites within a city
area.
MIB (Management Information Base)
A data structure used for communication and control of the probe.
MPOA (Multiprotocol over ATM)
A standardization of protocols for running multiple network layer protocols over
ATM.
MsAU (Media station Access Unit)
The attachment unit used to provide the physical connection and access to a
Token-Ring network.
Multiplexer
A network element (NE) that performs multiplexing of several signals into one, or
separates out the individual signals at the receiving end. An add-drop multiplexer
can insert a tributary signal into a signal stream at a node, or extract a tributary
signal from a stream at a node.
Multiplexing
Merging several different signals into one at the source, and separating them at the
destination, for example, the sound and video of a television signal are
multiplexed (modulated) onto a single carrier. In ATM telecommunications,
multiplexing refers to the merging of several service signals consisting of ATM
cells with different VPI and VCI values into a single cell stream modulated onto
an optical carrier at a particular line rate (for example, 155.52 Mb/s).
NetMetrix
NetMetrix refers to the HP OpenView NetMetrix/UX software suite for HP-UX
and Solaris.
