      (Ukukhululeka ngokomzimba）

Uhlolojikelele

Lesi siguquli esibonakalayo sisekelwe ku-FPGA. Ingabona ukudluliswa kwedatha ye-4Channel Ethernet ngamasekethe angu-1E1,nikeza abasebenzisi ukufinyelela kwe-Ethernet ngenani lika-1984K. Isetshenziswa kakhulu eminyangweni yezezimali, yezokuphepha kanye nezokuphepha okudingeka ihlinzekwe ngamanethiwekhi amabili ahlukene, futhi kokubili kunethiwekhi ebonakalayo ingahlukaniswa ngokuphelele. Isibonelo, inethiwekhi yebhizinisi yesistimu yezezimali, inethiwekhi yehhovisi yangaphakathi kanye nenethiwekhi yebhizinisi ayikwazi ukuxhunywa ndawonye. Lesi multiplexer esibonakalayo singayixazulula le nkinga.

• Yiba nomsebenzi wokuzisetha kabusha we-Ethernet, okokusebenza ngeke kufe
• 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)
• Nikeza ama-impedances angu-2: 75 Ohm ukungalingani kanye nebhalansi engu-120 Ohm;
• Qaphela ukuqapha izinga lokushisa lemishini ekude kanye ne-voltage emishinini yasendaweni;
• Ukusekela Ukuphathwa Kwenethiwekhi ye-SNMP;
