Kakaretso

E1-4ETH interface converter e thehiloe ho FPGA. Sesebelisoa se fana ka phetoho lipakeng tsa ITU-T G.703 (E1) sebopeho sa E1 se hlophisitsoeng hantle le sebopeho sa 10/100Base-T. Ke borokho ba Ethernet bo nang le bokhoni bo phahameng, bo ikamahanyang le maemo a malelele. Sehlahisoa se nyane ebile se theko e tlase. E sebelisoa haholo ho hokahanya pakeng tsa WAN le LAN, ho shebella, joalo-joalo
