Kakaretso

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.
