Wannan mai sauya mu'amala ya dogara ne akan FPGA, ta amfani da fasaha mai juzu'in juzu'i don haɗawa da da'irori na E1 da yawa don watsa bayanan Ethernet na 100BASE-TX. Yana iya gane tashar 1-8E1 don canzawa tsakanin keɓancewar gani na Ethernet. Wannan na'urar na iya aika ma'aunin siginar transceiver zuwa nuni zuwa Ethernet Optical interface don yin tashoshi E1 masu haɗin gwiwa tare da keɓancewar gani na Ethernet. Daban-daban tare da gadar cibiyar sadarwar nesa ta gabaɗaya, wannan na'urar zata iya tallafawa daidaitawar tashar tashar 1-8Channel E1, zata iya gano adadin E1 ta atomatik kuma zaɓi E1 da ke akwai. Yana ba da damar bambancin jinkirin watsa E1 Lines. bambancin jinkiri.
