Wannan mai sauya mu'amala yana dogara ne akan FPGA, yana ba da ƙirar E1 mai ƙira guda ɗaya da ƙirar Ethernet guda ɗaya don cimma watsa bayanan Ethernet na 10/100Base-T akan tashar E1. Babban aiki ne, gadar Ethernet mai koyon kai. Wannan na'urar ita ce na'urar faɗaɗawa ta Ethernet, ta amfani da hanyar sadarwa (PDH/SDH/Microwave) wanda ke samar da tashar E1 don cimma haɗin haɗin gida da na nesa na Ethernet tare da musaya na layi a farashi mai sauƙi. Na'urar tana da aikin gwajin madauki na tsaka-tsaki don sauƙaƙe ƙaddamar da aikin da kiyayewa yau da kullun.
