Theko e Tlase ka ho Fetisisa Rs422 Multiplexer - E entsoe ka E1-FE+4RS232 segokanyimmediamentsi sa sebolokigolo JHA-CE1F1R4 – JHA

Kakaretso

Sefetoleli sena sa protocol (interface converter) se sebelisa moralo o moholo oa FPGA, se fana ka sebopeho sa E1 le sehokelo sa Ethernet le li-interfaces tse 'ne tsa serial, hoa khoneha ho fihlela data ea 10 / 100Base-T Ethernet ka phetiso ea liteishene tsa E1, ke ts'ebetso e phahameng, boinotšing. -ho ithuta borokho ba Ethernet. Sesebelisoa se sebetsa e le katoloso ea lisebelisoa tsa Ethernet, ts'ebeliso ea marang-rang a teng (PDH / SDH / microwave, joalo-joalo) e fanoeng ke likanale tsa E1 ho hokahanya lipheletsong tse peli tsa theko e tlase ea Ethernet le likhokahano tsa serial. Bokhoni ba lisebelisoa tsa tlhahlobo ea loop ho thusa ho bula le ho lokisa mesebetsi e tloaelehileng.
