2019 Ikhwalithi ephezulu yama-Rs232 ukuya ku-Rs485 - Isiguquli esibonakalayo se-E1-4FE esizimele JHA-CE1fF4 - JHA

Isiguquli esibonakalayo se-E1-4FE esizimeleI-JHA-CE1fF4

Uhlolojikelele

Isiguquli esibonakalayo se-E1-4ETH sisekelwe ku-FPGA. Idivayisi ihlinzeka ngoshintsho phakathi kwe-ITU-T G.703 (E1) isixhumi esibonakalayo se-E1 enozimele kanye nesixhumi esibonakalayo esingu-10/100Base-T. Yibhuloho le-Ethernet lebanga elide elinamandla, elikwazi ukuzivumelanisa nalo. Umkhiqizo mncane futhi ubiza kancane. Isetshenziswa kabanzi ekuxhumeni phakathi kwe-WAN ne-LAN, ukuqapha, njll

Isithombe Somkhiqizo

Izici

• Ngokusekelwe ku-IC ye-self-copyright
• I-E1 isekela noma iyiphi isethi yesikhathi, izinga lingu-64K-2048K
• Ingabona ukuqapha nokulawula imishini ekude, idatha yokuphatha ye-OAM ayizange ithathe isikhathi somsebenzisi futhi ilondoloze umkhawulokudonsa we-E1
• Yiba nomsebenzi we-E1 interface loop back check, gwema isiguquli siphahlazekile ngenxa ye-interface loop return; Yiba nesikhombi lapho idivayisi icishiwe noma
• Umugqa we-E1 uphukile noma ulahlekelwe isignali;
• Ingasetha umugqa we-E1 ukuthi ungathumeli isignali ye-LINK kusixhumi esibonakalayo se-Ethernet ngenkathi umugqa we-E1 uphukile;
• Isixhumi esibonakalayo se-Ethernet sisekela amafreyimu we-jumbo (1916 Bytes);
• I-4Channel 10M/100M Ethernet interface ingahlukanisana ukuze ibone ukuxhumana ngokuzimela;
• Isixhumi esibonakalayo se-Ethernet sisekela i-10M/100M, Ukuxoxisana okuzenzakalelayo kwesigamu/okugcwele okuyi-duplex kanye ne-AUTO-MDIX (umugqa oweqa futhi umugqa oqondile okwazi ukuzivumelanisa nezimo);
• Nikeza izinhlobo zewashi ezi-2: Iwashi eliyinhloko le-E1 kanye newashi lomugqa we-E1;
• Iba ne-Loop Back Mode emithathu: i-E1 interface Loop Back (ANA),Isixhumi esibonakalayo se-Ethernet Loop Back(DIG),Yala isixhumi esibonakalayo se-Ethernet esikude Loop Back(REM)
• Yiba nomsebenzi wokuhlola ikhodi okungahleliwe mbumbulu, ukufakwa kalula nokugcinwa;
• Nikeza ama-impedances angu-2: 75 Ohm ukungalingani kanye nebhalansi engu-120 Ohm;
• Yiba nomsebenzi wokuzisetha kabusha we-Ethernet, okokusebenza ngeke kufe
• Isixhumi esibonakalayo se-Ethernet sisekela izinto zokubala zokwamukela nokudlulisa ifremu, ithola izinto zokubala zefreyimu ezingalungile.Isixhumi esibonakalayo se-E1 sisekela izinto zokubala zokwamukela uhlaka olungalungile;
• Qaphela ukuqapha izinga lokushisa lemishini ekude kanye ne-voltage emishinini yasendaweni;
• Ukusekela Ukuphathwa Kwenethiwekhi ye-SNMP;
• Ingakha isakhiwo: I-Ethernet E1 Bridge(A)----E1 I-Optical Fiber Modemu(B)----Imodemu ye-Ethernet Optical Fiber (C)
