(Logical lsolation)

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 4Channel 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 akaretsang ba marang-rang, sesebelisoa sena se 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. E lumella phapang ea nako ea phetisetso ea mela ea E1.

• E ipapisitse le IC ea boinotšing
• Ho fihlella phetiso e hlakileng ea data ea Ethernet ho lipotoloho tsa 1-8E1
• E khona ho hlokomela hore sesebelisoa sa lehae le se hole se seta bocha
• Ethernet Interface ke 100BASE-FX, e tšehetsa protocol ea VLAN
• Inter-set dynamic Ethernet MAC address (4,096) e nang le ts'ebetso ea ho sefa ea data ea lehae
• Sekhahla sa mela ea Channel e le 'ngoe ke 1984Kbit/s, 8Channel Bandwidth e fihla ho 7936Kbit/s.
• Sehokelo sa Ethernet sa Channel 10M/100M se ka itšehla thajana ho hlokomela puisano ka boikemelo
• Sehokelo sa Ethernet se ts'ehetsa 10M/100M, halofo / e felletseng ea duplex e ikamahanyang le maemo le AUTO-MDIX (mohala o tšekaletseng le mohala o hokahantsoeng ka kotloloho o ikamahanyang le maemo)
• 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 sekhahla sa phoso sa 2M sa potoloho ea onedirection se feta moeli, ho khaola lehlakoreng lena ha ho amehe; ke ho re, bobeli ba Ethernet directiontransmission e ka ba asymmetric
• Lumella phapang ea nako ea phetisetso ea 8Channel E1 100ms. Ha moeli o feta moeli o lumelletsoeng, sistimi e ka emisa E1 ka bo eona hore ho lieha ha nako ho kholo haholo ho romella 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 mocha o sebetsang oa E1 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;
