Beddelka Qeexida sare ee Rs485 - 4E1-4FE Interface Beddelka JHA-CE4F4 (Logical lsolation) - JHA

Dulmar

Beddeliyaha interface-ku wuxuu ku saleysan yahay FPGA, iyadoo la adeegsanayo tignoolajiyada isku dhufashada jihada rogan si loogu xidho wareegyo badan oo E1 ah si loo gudbiyo xogta Ethernet ee 4Channel 100BASE-TX. Waxay ogaan kartaa 1 ~ 4 E1 kanaalka si loogu beddelo inta u dhaxaysa interface interface Ethernet. Qalabkani waxa uu u gudbin karaa barta signalka gudbiyaha si uu u tilmaamo xidhiidhka indhaha ee Ethernet si uu u sameeyo kanaalada E1 ee isku xidhan ee isku xidhka indhaha ee Ethernet. Si ka duwan buundada guud ee fog fog, qalabkani wuxuu taageeri karaa 1-4Channel E1 qaabeynta kanaalka, wuxuu si toos ah u ogaan karaa tirada E1 oo uu dooran karaa E1 la heli karo. Waxay u ogolaataa E1 khadadka gudbinta waqtiga farqiga daahitaanka.

Astaamaha

• Iyada oo ku saleysan is-copyright IC
• Si loo gaaro gudbinta hufan ee xogta Ethernet ee wareegyada 1-4E1
• Waxa uu ogaan karaa dib u dajinta qalabka deegaanka iyo kan fog
• Interface Ethernet waa 100BASE-FX, waxay taageertaa borotokoolka VLAN
• Inter-set dynamic Ethernet MAC ciwaanka (4,096) oo leh hawl shaandhayn xogta gudaha ah
• Qiimaha khadadka hal kanaalka ah waa 1984Kbit/s, 4Channel Bandwidth waa ilaa 7936Kbit/s
• Kanaalka 10M/100M Ethernet interface ayaa midba midka kale ka go'doomin karaa si loo gaaro isgaarsiin si madax-bannaan
• Isku xirka Ethernet wuxuu taageeraa 10M/100M, badh/buuxa laba-labo-bole oo iswada la qabsan kara iyo AUTO-MDIX
• Heerka digniinta tooska ah ee CRC ayaa la dejin karaa si loo go'doomiyo xadhkaha gudbinta tayada liita oo la gooyo hal jiho. Marka 2M laanta wareega haljiho heerka qaladka uu dhaafo xadka, jarista jihadan ma saameynayso; taas oo ah in la yiraahdo, labadaba gudbinta jihada Ethernet waxay noqon karaan asymmetric
• Oggolow 4-Channel E1 farqiga wakhtiga gudbinta 100ms. Marka xadku dhaafo xadka la ogol yahay, nidaamku si toos ah ayuu u joogsan karaa E1 in daahitaanku aad u weyn yahay si loo diro xogta
• E1 interface waa waafaqsan ITU-T G.703, G.704 iyo G.823, ma taageeraan isticmaalka signal timeslot
• Module interface E1 oo leh wareegga soo kabashada saacada isku-xidhka ah iyo wareegga code ee HDB3
• Taageerada E1 kanaalka kulul ee qalabka, oo si toos ah u ogaanaya kanaalka E1 ee waxtarka leh mana joojin doono gudbinta xogta
• Waxay taageeri kartaa 1-4Channel E1 qaabeynta kanaalka, si toos ah u ogaan kara tirada E1 oo dooro E1 la heli karo;
