Dubawa

Wannan mai mu'amala da mu'amala ya dogara ne akan FPGA. Multiplex 10/100Base-T Ethernet 2Channel interface zuwa E1 dubawa don samar da masu amfani tare da hanyar Ethernet a ƙimar 1984K. Ana amfani da shi sosai a fannin kuɗi, tsaro da sassan tsaro waɗanda ke buƙatar samar da hanyoyin sadarwa daban-daban guda biyu, kuma duka akan hanyar sadarwa ta zahiri za a iya raba su gaba ɗaya. Misali, tsarin hada-hadar kasuwanci na tsarin kudi, cibiyar sadarwa na ofis na ciki da cibiyar sadarwar kasuwanci ba za a iya haɗa su tare ba. Wannan dubawa multiplexer zai iya magance wannan matsala.
