Agilent Technologies J3972A Media Filter, Metropolitan Area Network MAN, Multiplexer, NetMetrix

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.
