Umgangatho ogqwesileyo we-Usb Ukuya kwi-Rs485 422 Isiguquli-Isiguquli se-E1-4FE esakhiweyo se-Fremed JHA-CE1fF4-JHA

I-Fremed E1-4FE interface ConverterJHA-CE1fF4

Isishwankathelo

I-E1-4ETH umguquleli we-interface isekwe kwi-FPGA. Isixhobo sibonelela ngenguqu phakathi kwe-ITU-T G.703 (E1) i-interface eqingqiweyo ye-E1 eqingqiweyo kunye ne-10/100Base-T interface. Inamandla aphezulu, ibhulorho ye-Ethernet ekwazi ukuziqhelanisa nomgama omde. Imveliso incinci kwaye iphantsi. Isetyenziselwa ngokubanzi ukudibanisa phakathi kwe-WAN kunye ne-LAN, ukubeka iliso, njl

Uhlobo oluncinci

Iimbonakalo

• Ngokusekwe kwi-self-copyright IC
• I-E1 ixhasa nayiphi na i-timelot set, ireyithi yi-64K-2048K
• Unokuqonda ukubeka iliso kunye nokulawulwa kwezixhobo ezikude, idatha yolawulo lwe-OAM ayizange ithathe ixesha lomsebenzisi kwaye igcine i-E1 bandwidth
• Yiba nomsebenzi we-E1 ujongano lwelophu ngasemva ukujonga, nqanda isiguquli singqubekile ngenxa yokubuya kojongano lwelophu; Yiba nesalathisi xa isixhobo sicinyiwe okanye
• Umgca we-E1 uphukile okanye ulahlekelwe ngumqondiso;
• Unokuseta umgca we-E1 ukuba ungathumeli isignali ye-LINK kwi-interface ye-Ethernet ngelixa umgca we-E1 uphukile;
• Ujongano lwe-Ethernet luxhasa iifreyimu zejumbo (1916 Bytes);
• I-4Channel 10M/100M Ethernet interface inokwahlula omnye komnye ukuze iqonde unxibelelwano ngokuzimeleyo;
• I-interface ye-Ethernet ixhasa i-10M / 100M, isiqingatha / i-duplex epheleleyo yokuThetha i-auto-Negotiation kunye ne-AUTO-MDIX (umgca onqamlekileyo kunye nomgca odibeneyo onokuziqhelanisa);
• Ukubonelela ngeentlobo zewotshi ezi-2: I-E1 master clock kunye ne-E1 line clock;
• Yiba neNdlela yokuNgena kweLoop emithathu: I-E1 interface yeLoop Back (ANA),Ujongano lweEthernet Loop Back(DIG),Yalela ujongano olude lwe-Ethernet Loop Back(REM)
• Yiba nomsebenzi wokuvavanya ikhowudi ye-pseudo, kulula ukufakela kunye nokugcinwa;
• Ukubonelela nge-2 impedances: 75 Ohm unbalance kunye ne-120 Ohm ibhalansi;
• Yiba ne-Ethernet esweni ukuseta kwakhona umsebenzi, izixhobo aziyi kufa
• Ujongano lwe-Ethernet luxhasa izixhobo zokubala zokufumana kunye nokuhambisa isakhelo, ifumana izixhobo zokubala ezingalunganga.Ujongano lwe-E1 luxhasa izixhobo zokubala zokufumana isakhelo esingalunganga;
• Ukuqonda ukubeka iliso kubushushu besixhobo esikude kunye nombane osuka kwisixhobo sendawo;
• Inkxaso yoLawulo lweNethiwekhi yeSNMP;
• Inokwenza isakhiwo: I-Ethernet E1 Bridge (A)---E1 iModem yeFayibha yokubona (B)---Imodem ye-Ethernet yeFayibha ye-Optical (C)
