2019 Idizayini Entsha YaseShayina engu-16e1 Kuya ku-4ethernet Converter - Isiguquli esibonakalayo se-E1-FE esinohlaka ngohlaka JHA-CE1fF1 - JHA

Isiguquli esibonakalayo se-E1-FE esizimele I-JHA-CE1fF1

Uhlolojikelele

Lesi siguquli esibonakalayo sisekelwe ku-FPGA, sinikeza isixhumi esibonakalayo se-E1 esinozimele kanye nesixhumi esibonakalayo esisodwa se-Ethernet ukuze kuzuzwe ukudluliswa kwedatha ye-10/100Base-T Ethernet esiteshini se-E1. Iwukusebenza okuphezulu, ibhuloho le-Ethernet lokuzifundela. Le divayisi iyidivayisi enwetshiwe ye-Ethernet, isebenzisa inethiwekhi (i-PDH/SDH/Microwave) ehlinzeka ngesiteshi se-E1 ukuze kufinyelelwe ukuxhumana kwe-Ethernet yasendaweni nesilawuli kude nezixhumi ezibonakalayo ze-serial ngezindleko eziphansi. Idivayisi inomsebenzi wokuhlola i-inter-set loop ukusiza ukuqaliswa kwephrojekthi nokugcinwa kwansuku zonke.

Izici

• Ngokusekelwe ku-IC ye-self-copyright
• Ingabona ukuqapha nokulawula imishini ekude, idatha yokuphatha ye-OAM ayizange ithathe isikhathi somsebenzisi futhi ilondoloze umkhawulokudonsa we-E1
• I-E1 isekela noma iyiphi isethi yesikhathi, izinga lingu-64K-2048K
• Idivayisi yasendaweni ingaphoqa ukuthi izinga ledivayisi elikude liyilandele
• Yiba nomsebenzi we-E1 interface loop back check, gwema isiguquli siphahlazekile ngenxa ye-interface loop return;
• Yiba nesikhombi lapho idivayisi icishiwe noma ulayini we-E1 uphukile noma ulahlekelwa isignali;
• Ingasetha umugqa we-E1 ukuthi ungathumeli isignali ye-LINK kusixhumi esibonakalayo se-Ethernet ngenkathi umugqa we-E1 uphukile;
• I-interface ye-Ethernet isekela amafreyimu we-jumbo (2036 Bytes);
• Ikheli le-Inter-set eliguqukayo le-Ethernet MAC (4,096) elinokuhlunga kohlaka lwedatha yendawo
• Isixhumi esibonakalayo se-Ethernet sisekela i-10M/100M, isigamu/egcwele i-duplex auto- Negotination kanye ne-AUTO-MDIX (umugqa oweqa futhi umugqa oqondile okwazi ukuzivumelanisa nezimo);
• Yiba nomsebenzi wokuzisetha kabusha we-Ethernet, okokusebenza ngeke kufe
• Ingakwazi ukufeza izilungiselelo zedivayisi ekude noma iyiphi imodi ye-Ethernet futhi ingavala umsebenzi we-AUTO-MDIX;
• 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 isilawuli kude
• Isixhumi esibonakalayo se-Ethernet Loop Back(REM)
• Nikeza ama-impedances angu-2: 75 Ohm ukungalingani kanye nebhalansi engu-120 Ohm;
• Ukusekela Ukuphathwa Kwenethiwekhi ye-SNMP;
• Iyakwazi ukubona ukuqapha izinga lokushisa lemishini ekude kanye ne-voltage emishinini yendawo;
• Ingakha isakhiwo: I-Ethernet E1 Bridge(A)----E1 I-Optical Fiber Modemu(B)----Imodemu ye-Ethernet Optical Fiber (C)
• Ingakha isakhiwo: I-Ethernet E1 Bridge(A)----Optical Ethernet E1 Bridge (B)----Ethernet Optical Fiber Transceiver (C), ingaphatha (B) kanye no (C) kokuthi (A)
