I-wholesale yaseShayina engu-Rs232/Rs422/Rs485 Isiguquli - Isixhumi esibonakalayo Esingafakwanga E1-4FE Isiguquli JHA-CE1F4 – JHA

Isiguquli esibonakalayo se-E1-4FE esingazimele I-JHA-CE1F4

Uhlolojikelele

Lesi siguquli sephrothokholi (isiguquli se-interface) sisebenzisa idizayini enkulu ye-FPGA, i-ITU-T G.703 i-interface ye-E1 engafakwanga ngozimele kanye nesiguquli esibonakalayo se-10 / 100Base-T Ethernet ezine, iziteshi eziyi-10 / 100Base-T zizodluliselwa kuswishi, i-HUB, imizila. , amabhuloho, noma enye idivayisi. Futhi ngokusebenzisa i-Optical nezinye izinto zokuthutha zadluliswa, ukuxhumana kungakhiwa izingxenye zenethiwekhi ezihlukene. Le divayisi iwukusebenza okuphezulu, ibhuloho le-Ethernet elikude eliguqukayo. Usayizi wayo omncane, izindleko eziphansi, zilungele kakhulu izinhlelo zokusebenza zokuvala amabhuloho ezingazweli kakhulu noma njenge-LAN extender noma i-slicer bitstream kungqalasizinda. Ingafunda ngokuzenzakalelayo ikheli le-LAN MAC eliqhubekayo ekhelini okuyiwa kulo lohlaka nokunye ukudlulisela phambili kwe-LAN. Kuphrothokholi ye-TCP / IP esobala, nikeza ukuvikeleka kwenethiwekhi yokuxhumana phakathi kwamadivayisi ahlukile wokuxhumana, ukuxhumana okungenamthungo. Le mishini isetshenziswa kabanzi phakathi kwe-WAN ne-LAN networking, inkambu yokuqapha

Izici

• Ngokusekelwe ku-IC ye-self-copyright
• Ingabona ukuqapha nokulawula okokusebenza okukude, idatha yokuphatha ye-OAM ayizange ithathe isikhathi esibekiwe sabasebenzisi futhi yonge 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 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; Isixhumi esibonakalayo se-Ethernet sisekela amafreyimu we-jumbo (1916 Bytes);
• I-4Channel 10M/100M Ethernet interface ingahlukanisa ukuze ibone ukuxhumana ngokuzimela;
• Isixhumi esibonakalayo se-Ethernet sisekela i-10M/100M, i-duplex auto-Negotiation eyingxenye/egcwele 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 uhlaka, zithola izinto zokubala zozimele ezingalungile. I-interface ye-E1 isekela izinto zokubala zokwamukela ifreyimu engalungile;
• Ukusekela Ukuphathwa Kwenethiwekhi ye-SNMP;
• Qaphela ukuqapha izinga lokushisa lemishini ekude kanye ne-voltage emishinini yasendaweni;
• Ingakha isakhiwo: I-Ethernet E1 Bridge(A)－--E1 I-Optical Fiber Modemu(B)－--Imodemu ye-Ethernet Optical Fiber (C)
