Sesebelisoa sena sa ho fetolela se ipapisitse le FPGA.E khona ho hlokomela phetiso ea data ea 4Channel Ethernet ho feta lipotoloho tsa 1E1,fa basebelisi phihlello ea Ethernet ka sekhahla sa 1984K.E sebelisoa haholo mafapheng a lichelete, a tšireletso le a tšireletso a hlokang ho fanoa ka marang-rang a mabeli a fapaneng, 'me ka bobeli ka marang-rang a' mele a ka aroloa ka ho feletseng.Ka mohlala, marang-rang a khoebo ea tsamaiso ea lichelete, marang-rang a ofisi ea ka hare le marang-rang a khoebo a ke ke a hokahana hammoho.Multiplexer ena e ka rarolla bothata bona.
