Phatlalatso e potlakileng Thepa ea Ethernet - 8E1-1FE segokanyimmediamentsi sa sebolokigolo JHA-CE8F1 – JHA

Kakaretso

Sesebelisoa sena sa ho fetolela se ipapisitse le FPGA, se sebelisa theknoloji ea reverse direction multiplexing ho bokella lipotoloho tse ngata tsa E1 ho fetisetsa data ea Ethernet ea 100BASE-TX. E ka hlokomela mocha oa 1-8E1 ho fetolela lipakeng tsa Ethernet optical interface. Sesebelisoa sena se ka fetisetsa ntlha ea lets'oao la transceiver ho supa ho Ethernet optical interface ho etsa hore likanale tsa E1 li hokahane le Ethernet optical interface. Ho fapana le borokho bo tloaelehileng ba marang-rang, sesebelisoa sena se ka tšehetsa tlhophiso ea mocha oa 1-8Channel E1, e khona ho lemoha palo ea E1 ka bo eona ebe e khetha E1 e fumanehang. E lumella phapang ea nako ea phetisetso ea mela ea E1. tieho phapang.

• Mohaho oa alamo oa CRC o ka beoa ho arola melapo ea phetisetso ea boleng bo bobe le ho khaola tsela e le 'ngoe. Ha potoloho ea lekala ea 2M lebelo la phoso ea tataiso e le 'ngoe e feta moeli, ho khaola tsela ena ka lehlakoreng le leng ha e amehe; ke hore, phetiso ea Ethernetdirection ka bobeli e ka ba asymmetric
• Lumella phapang ea nako ea phetisetso ea 8Channel E1 100ms. Ha moeli o feta moeli o lumelletsoeng, tsamaiso e ka emisa ka ho toba ho E1 hore nako ea ho lieha e kholo haholo ho romela data
• Sebopeho sa E1 se lumellana le ITU-T G.703, G.704 le G.823, ha se tšehetse tšebeliso ea nako ea nako ea pontšo.
• E1 segokanyimmediamentsi sa sebolokigolo le inter-set seti oa ho hlaphoheloa potoloho le HDB3 khoutu potoloho
• Ts'ehetsa plug e chesang ea E1 sesebelisoa, 'me e iphumanela e sebetsang
• mocha mme e ke ke ea sitisa phetiso ea data
• E ka ts'ehetsa tlhophiso ea mocha oa 1-8Channel E1, e khona ho bona palo ea E1 ka bo eona ebe e khetha E1 e fumanehang;
