Wannan mai canza yarjejeniya (mai canza mu'amala) ta yin amfani da ƙirar FPGA mai girma, samar da ƙirar E1 da keɓaɓɓiyar keɓancewa da keɓancewar Ethernet da muƙamuƙi guda huɗu, yana yiwuwa a cimma bayanan 10 / 100Base-T Ethernet akan watsa tashoshin E1, babban aiki ne, kai tsaye. - koyo Ethernet gada. Na'urar tana aiki azaman faɗaɗa na'urorin Ethernet, amfani da cibiyoyin sadarwa masu wanzuwa (PDH / SDH / microwave, da sauransu) waɗanda tashoshin E1 suka samar don haɗa ƙarshen ƙarshen Ethernet mai ƙarancin farashi da musaya na serial. Ƙwararren kayan aikin gwaji na madauki don sauƙaƙe buɗewa da ayyukan kulawa na yau da kullun.
