Liistada Qiimaha ee Rs485 422 Beddeleyaasha - 8E1-1FE interface beddelka JHA-CE8F1 – JHA

Dulmar

Beddelahan is-dhexgalku wuxuu ku salaysan yahay FPGA, iyadoo la adeegsanayo tignoolajiyada isku-dhufashada jihada rogan si loogu xidho wareegyo badan oo E1 ah si loo gudbiyo xogta Ethernet ee 100BASE-TX. Waxay ogaan kartaa kanaalka 1-8E1 si loogu beddelo inta u dhaxaysa interface-ka indhaha ee 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. Kala duwanaanshaha buundada guud ee fogaanta, qalabkani wuxuu taageeri karaa 1-8Channel 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. dib u dhigista farqiga.

Astaamaha

• Iyada oo ku saleysan is-copyright IC
• Si loo gaaro gudbinta hufan ee xogta Ethernet ee wareegyada 1-8E1
• 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
• Taageer dhammaan habka shaqada ee Ethernet
• 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 wareegta hal jiho heerka qaladka ka sare maro, goynta jihada kale ma saamayn; taas oo ah in la yiraahdo, labadaba gudbinta jihada Ethernet waxay noqon kartaa asymmetric
• U ogolow 8Channel E1 kala duwanaanshaha 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 waxtarka
• kanaalka mana joojin doono gudbinta xogta
• Waxay taageeri kartaa 1-8Channel E1 qaabeynta kanaalka, si toos ah u ogaan kara tirada E1 oo dooro E1 la heli karo;
