Jumla Mai Canjin Mutuwar Ma'amala ta China Rs485 - 4E1-4FE Mai Canja wurin Mutuwar Ma'amala JHA-CE4F4 (Logical lsolation) - JHA

Dubawa

Wannan mai juyawa yana dogara ne akan FPGA, ta yin amfani da fasaha mai jujjuya alkibla don haɗawa don da'irori na E1 da yawa don watsa bayanan Ethernet na 4Channel 100BASE-TX. Yana iya gane tashar 1 ~ 4 E1 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. Ba kamar gadar cibiyar sadarwar nesa ta gabaɗaya ba, wannan na'urar na iya tallafawa daidaitawar tashar tashar 1-4Channel E1, tana iya gano adadin E1 ta atomatik kuma zaɓi E1 da ke akwai. Yana ba da damar bambancin jinkirin watsa E1 Lines.
