I-4E1-1FE isixhumi esibonakalayo Isiguquli se-JHA-CE4F1 Uhlolojikelele Lesi siguquli esisebenzisana naye sisekelwe ku-FPGA, sisebenzisa ubuchwepheshe bokuphindaphinda besiqondisindlela esibuyela emuva ukuze sihlanganise amasekhethi amaningi e-E1 ukuze kudluliselwe idatha ye-Ethernet ye-4Channel 100BASE-TX. Ingakwazi ukubona ishaneli engu-1~4 E1 ukuze iguqule phakathi kwesixhumi esibonakalayo se-Ethernet. Le divayisi ingadlulisela indawo yesignali ye-transceiver ukuze ikhombe ku-Ethernet optical interface ukuze yenze amashaneli e-E1 axhumeke nge-Ethernet optical interface. Ngokungafani nebhuloho lenethiwekhi elikude elivamile, lolu cingo lungasekela ukumiswa kwesiteshi se-1-4Channel E1, lukwazi ukubona ngokuzenzakalelayo inombolo ye-E1 bese lukhetha i-E1 etholakalayo. Ivumela umehluko wesikhathi sokulibaziseka wokudlulisa imigqa ye-E1. Isithombe Somkhiqizo Esincane Uhlobo Oluyi-19 Intshi 1U Uhlobo Izici Ezisekelwe ku-IC yelungelo lobunikazi Ukufeza ukudluliswa kwedatha ye-Ethernet esobala kumasekhethi angu-1-4E1 Ingabona ukuthi idivayisi yokusetha kabusha i-Ethernet Interface iyi-100BASE-FX, isekela iphrothokholi ye-VLAN I-Inter-set dynamic Ethernet Ikheli le-MAC (4,096) elinomsebenzi wokuhlunga uhlaka lwedatha yendawo Izinga lemigqa Yesiteshi esisodwa ngu-1984Kbit/s, 4Channel Umkhawulokudonsa ungafika ku-7936Kbit/s Ukusekela yonke isethi ye-alamu ye-Ethernet Work Mode CRC ingasethwa ukuze ihlukanise imigqa yokudlulisela yekhwalithi embi futhi kunqanyulwe indlela eyodwa. Uma isekethe yegatsha engu-2M isilinganiso sephutha lesiqondisindlela esisodwa sidlula umkhawulo, ukunqamula le ndlela kolunye uhlangothi akuthintwa; okusho ukuthi, kokubili ukudluliswa kwesiqondiso se-Ethernet kungaba yi-asymmetric Vumela umehluko wesikhathi sokudlulisa we-4Channel E1 ongu-100ms. Uma imajini idlula ibanga elivunyelwe, isistimu ingamisa ngokuzenzakalelayo ku-E1 ukuthi ukubambezeleka kukhulu kakhulu ukuthumela idatha ye-E1 interface ihambisane ne-ITU-T G.703, G.704 ne-G.823, ingasekeli ukusetshenziswa kwesignali Imojula yesixhumi esibonakalayo se-timeslot E1 enesekhethi yokutakula iwashi eliphakathi nesethi kanye nesekethe yekhodi ye-HDB3 Sekela ipulaki eshisayo engu-E1 kudivayisi, futhi ithola ngokuzenzakalelayo isiteshi esisebenzayo futhi ngeke iphazamise ukudluliswa kwedatha Ingasekela i-1-4Channel Ukucushwa kwesiteshi se-E1, kungathola ngokuzenzakalelayo inombolo ye-E1 bese ukhetha i-E1 etholakalayo; Amapharamitha ♦ Izinga le-E1 Interface Interface: hambisana nephrothokholi G.703; Isilinganiso sokusebenzisana: n*64Kbps±50ppm; Ikhodi Yesixhumanisi: HDB3; Ukuphazamiseka kwe-E1: 75Ω (ukungalingani), 120Ω (ibhalansi); Ukubekezelela i-Jitter: Ngokuvumelana nephrothokholi G.742 kanye ne-G.823 Ukunakwa Okuvunyelwe: 0~6dBm ♦ I-interface ye-Ethernet(100/100M) Izinga le-Interface: 10/100 Mbps, uhhafu/ogcwele i-duplex auto-negotiation Interface Standard: Ihambisana ne-IEEE 802. , IEEE 802.1Q (VLAN) MAC Amandla ekheli: 4096 Isixhumi: RJ45, sisekela i-Auto-MDIX ♦ Indawo yokusebenza Izinga lokushisa: -10°C ~ 50°C Umswakamo osebenzayo: 5%~95 % (akukho condensation) Izinga lokushisa lesitoreji: -40°C ~ 80°C Isitoreji Umswakamo: 5%~95 % (akukho ukufingqa) Ukucaciswa Inombolo Yemodeli: JHA-CE4F1 Incazelo Esebenzayo 4E1/1FE isikhombimsebenzisi Isiguquli se-Port Incazelo 4* E1 isixhumi esibonakalayo;1 *Isikhombimsebenzisi se-FE Amandla Amandla: AC180V ~ 260V;DC -48V;DC +24V;AC110VUkusetshenziswa kwamandla: ≤10W Dimension Usayizi Womkhiqizo: 216X140X31mm (WX1DXH3KG) Isisindo Isicelo Isixazululo esijwayelekile 1 Isixazululo esijwayelekile 2
