Inverse Multiplexer at both end.<br \/>\nIn electronics, a multiplexer (or mux) is a device that selects one of several analog or digital input signals and forwards the selected input into a single line. A multiplexer of 2n inputs has n select lines, which are used to select which input line to send to the output. Multiplexers are mainly used to increase the amount of data that can be sent over the network within a certain amount of time and bandwidth. A multiplexer is also called a data selector.<br \/>\nAn electronic multiplexer makes it possible for several signals to share one device or resource, for example one A\/D converter or one communication line, instead of having one device per input signal.<br \/>\nOn the other hand, a demultiplexer (or demux) is a device taking a single input signal and selecting one of many data-output-lines, which is connected to the single input. A multiplexer is often used with a complementary demultiplexer on the receiving end. An electronic multiplexer can be considered as a multiple-input, single-output switch, and a demultiplexer as a single-input, multiple-output switch<br \/>\nReferences: KRUTZ, Ronald L. &#038; VINES, Russel D., The CISSP Prep Guide: Mastering the Ten Domains of Computer Security, 2001, John Wiley &#038; Sons, Page 72. and <a href=\"https:\/\/secure.wikimedia.org\/wikipedia\/en\/wiki\/Multiplexer\" title=\"External link\" rel=\"nofollow noopener\" target=\"_blank\">https:\/\/secure.wikimedia.org\/wikipedia\/en\/wiki\/Multiplexer<\/a><\/div>\n<p><\/strong><\/span> <\/div>\n","protected":false},"excerpt":{"rendered":"<p>A common way to create fault tolerance with leased lines is to group several T1s together with an inverse multiplexer placed: A. at one end of the connection.
