Backplane
Backplane é um termo técnico relacionado a Central de Atendimento Telefônico.
Placa interna dos equipamentos DAC nas quais pode-se encaixar outras, a exemplo do que acontece com a placa-mãe dos computadores padrão IBM-PC.

É a placa onde está localizado o barramento, os conectores e também a alimentação. Nela se encaixam as diversas placas do equipamento.

- backplane ( Last modified: Tuesday, September 07, 2004)
(bak´plān) (n.) A circuit board containing sockets into which other circuit boards can be plugged in. In the context of PCs, the term backplane refers to the large circuit board that contains sockets for expansion cards.
Backplanes are often described as being either active or passive. Active backplanes contain, in addition to the sockets, logical circuitry that performs computing functions. In contrast, passive backplanes contain almost no computing circuitry.

Traditionally, most PCs have used active backplanes. Indeed, the terms motherboard and backplane have been synonymous. Recently, though, there has been a move toward passive backplanes, with the active components such as the CPU inserted on an additional card. Passive backplanes make it easier to repair faulty components and to upgrade to new components.
