Ixabiso eliphantsi kakhulu le-Rs422 Multiplexer-Ifreyim ye-E1-FE+4RS232 ujongano lokuguqulela JHA-CE1F1R4-JHA

Isishwankathelo

Le protocol converter (interface converter) usebenzisa isikali FPGA uyilo, ukubonelela ngesakhelo E1 ujongano kunye nojongano Ethernet kunye nojongano ezine serial, kuyenzeka ukuba kuphunyezwe 10 / 100Base-T Ethernet data phezu E1 ishaneli transmission, yintsebenzo ephezulu, self. -Ukufunda ibhulorho ye-Ethernet. Isixhobo sisebenza njengokwandiswa kwezixhobo ze-Ethernet, ukusetyenziswa kweenethiwekhi ezikhoyo (PDH / SDH / microwave, njl.) ezibonelelwa ngamajelo e-E1 ukudibanisa iziphelo zombini zexabiso eliphantsi le-Ethernet kunye ne-serial interfaces. Eyakhelwe-loop izixhobo zovavanyo ukuququzelela ukuvulwa kunye nemisebenzi yesiqhelo nokugcinwa.

Iimbonakalo

• Ngokusekwe kwi-self-copyright IC
• Unokuqonda ukubeka iliso kunye nokulawulwa kwezixhobo ezikude, idatha yolawulo lwe-OAM ayizange ithathe ixesha lomsebenzisi kwaye igcine i-E1 bandwidth
• I-E1 ixhasa nayiphi na i-timelot set, ireyithi yi-64K-2048K
• Isixhobo sasekhaya sinokunyanzela ireyithi yesixhobo esikude siyilandele
• Yiba nesalathisi xa isixhobo esikude sicinyiwe okanye umgca we-E1 waphukile okanye ulahlekelwe ngumqondiso;
• Yiba nomsebenzi we-E1 ujongano lwelophu ngasemva ukujonga, nqanda isiguquli singqubekile ngenxa yokubuya kojongano lwelophu;
• Ujongano lwe-Ethernet luxhasa iifreyimu zejumbo (2036 Bytes);
• I-Inter-set dynamic Ethernet idilesi ye-MAC (4,096) kunye nomsebenzi wokucoca isakhelo sedatha yendawo
• Ujongano lwe-Ethernet luxhasa i-10M/100M, isiqingatha / i-duplex epheleleyo ezenzekelayo- Uthethwano, inkxaso yeVLAN
• I-interface ye-Ethernet isekela i-AUTO-MDIX (umgca onqamlekileyo kunye nomgca odibeneyo odibeneyo onokuziqhelanisa);
• Yiba ne-Ethernet esweni ukuseta kwakhona umsebenzi, izixhobo aziyi kufa
• Ukubonelela ngeentlobo zewotshi ezi-2: I-E1 master clock kunye ne-E1 line clock;
• Ukubonelela nge-2 impedances: 75 Ohm unbalance kunye ne-120 Ohm ibhalansi;
• Inkxaso yoLawulo lweNethiwekhi yeSNMP
• Ujongano lweDatha yothotho inokuba yiRS232/RS422/RS485/TTL ngokuzithandela
• Ijelo lothotho linokusasaza idatha yothotho eguquguqukayo ngokuhambelana 300 Kbps-19200Kbps izinga le-baud
• Uthotho lwedatha yokuphindaphinda kwi-E1 inkxaso ye-ITU-T R.111 yokutsiba imo yekhowudi
• Idatha yothotho ye-RS232 yasekhaya inokuyalela irewuthi ye-RS232 yothotho lwedatha loop-umva kwindawo. Le loop- emva kwiringi yangaphandle ye-RS232 ujongano lwedatha, unokuvavanya i-chip ye-RS232 yojongano ngaphandle komonakalo.
• Uthotho lwezibuko ujongano lombane-ukhuseleko lufikeleleke kwi-IEC61000-4-5 (8/20μS) DM(Indlela eyamahluko): 6KV, Impedance (2 Ohm),CM(Indlela eqhelekileyo): 6KV, Imedance (2 Ohm) umgangatho
