2019 Umgangatho ophakamileyo we-Rs232 Ukuya kwi-Rs485 - 4E1-4FE Isiguquli se-Interface JHA-CE4F4 (i-Logical Lsolation)-JHA

Isishwankathelo

Lo mguquli we-interface usekelwe kwi-FPGA, usebenzisa iteknoloji ye-reverse direction multiplexing ukudibanisa kwiisekethe ezininzi ze-E1 ukuhambisa idatha ye-Ethernet ye-4Channel 100BASE-TX. Iyakwazi ukuqonda i-1 ~ 4 itshaneli ye-E1 yokuguqula phakathi kojongano olubonakalayo lwe-Ethernet. Esi sixhobo sinokuthumela indawo yomqondiso we-transceiver ukukhomba kwi-Ethernet ujongano optical ukwenza itshaneli ze-E1 ezidityaniswe ne-Ethernet ujongano optical. Ngokungafaniyo nebhulorho yothungelwano olukude ngokubanzi, esi sixhobo sinokuxhasa i-1-4Channel E1 ubumbeko lwetshaneli, inokubona ngokuzenzekelayo inani le-E1 kwaye ukhethe i-E1 ekhoyo. Ivumela ukulibaziseka kwexesha lokudluliselwa kwemigca ye-E1.

Iimbonakalo

• Ngokusekwe kwi-self-copyright IC
• Ukufezekisa ukuhanjiswa kwedatha ecacileyo ye-Ethernet kwiisekethe ze-1-4E1
• Iyakwazi ukubona indawo kunye nokusetwa kwakhona kwesixhobo esikude
• I-Ethernet Interface yi-100BASE-FX, inkxaso yeprotocol yeVLAN
• I-Inter-set dynamic Ethernet idilesi ye-MAC (4,096) kunye nomsebenzi wokucoca isakhelo sedatha yendawo
• Ireyithi yelayini yesijelo esinye yi-1984Kbit/s, i-4Channel Bandwidth ifikelela kwi-7936Kbit/s
• I-Channel 10M/100M Ethernet interface inokwahlula omnye komnye ukuze iqonde unxibelelwano ngokuzimeleyo
• Ujongano lwe-Ethernet luxhasa i-10M/100M, isiqingatha/i-duplex epheleleyo ekwaziyo ukuziqhelanisa ne-AUTO-MDIX (umgca onqamlezileyo kunye nomgca odityanisiweyo ngokuthe tye okwazi ukuziqhelanisa)
• Umda we-alam ozenzekelayo we-CRC unokusetwa ukwahlula iintambo zothumelo ezikumgangatho ombi kwaye unqunyulwe umkhombandlela omnye. Xa i-2M yesebe yesekethe ireyithi yempazamo ye-onedirection idlula umqobo, ukusika kweli cala kwelinye icala akuchaphazeleki; oko kukuthi, zombini i-Ethernet directiontransmission ingaba yi-asymmetric
• Vumela i-4-Channel E1 yokudluliselwa kwexesha lokulibaziseka umahluko 100ms. Xa umda udlula uluhlu oluvunyelweyo, inkqubo inokumisa ngokuzenzekelayo kwi-E1 ukuba ukulibaziseka kwexesha kukhulu kakhulu ukuthumela idatha
• I-E1 interface ihambelana ne-ITU-T G.703, G.704 kunye ne-G.823, ayixhasi ukusetyenziswa kwexesha lomqondiso wesignali
• Imodyuli yojongano lwe-E1 kunye nesekethe yokubuyisela iwotshi ephakathi kunye nekhowudi yekhowudi ye-HDB3
• Inkxaso yetshaneli ye-E1 eshushu-plug kwisixhobo, kwaye ibona ngokuzenzekelayo itshaneli ye-E1 esebenzayo kwaye ayiyi kuphazamisa ukuhanjiswa kwedatha.
• Inokuxhasa i-1-4Channel E1 yokucwangciswa kwesiteshi, inokubona ngokuzenzekelayo inani le-E1 kwaye ukhethe i-E1 ekhoyo;
