A multiplexor that adapts DS-1 circuits to a DS-3 circuit.
Mag Media
Magnetic data storage (e.g. floppy disk, hard drive, tape, etc.)
MAN - Metropolitan Area
Network
LANs interconnected within roughly a
50 mile radius. MANs typically use fiber optic cable to connect
various wire LANS. Transmission speeds may vary from 2 to 100
Mbps.

Modified Final
Judgement - MFJ
A 1982 court order issued by Federal Judge Harold H. Greene.
MFJ settled the 1974 antitrust suit and specified the divestiture
of AT&T. MFJ created the seven Regional Holding Companies
(Baby Bells), RBOCS,
LATAs, Equal Access, etc. AT&T
retained long-distance service and its manufacturing business. The
restriction that barred AT&T from entering the computer
business was lifted.
A single circuit or channel that has more than one connection on
one end. For example, 2 offices at one location sharing one line.
Multimedia
Computer systems that integrate audio, video & data.
Multiplexer - MUX
A device that combines 2 or more signals into a single
composite data stream for transmission on a single channel. For
example, an M1-3 MUX combines 28 DS-1s into a DS-3.
