Uhlolojikelele Lesi siguquli esibonakalayo sisekelwe ku-FPGA, sisebenzisa ubuchwepheshe bokubuyela emuva kokuphindaphinda ukuze kuhlanganiswe 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. Uhlobo Lwedeskithophu Yesithombe Somkhiqizo 19 Intshi 1U Uhlobo Izici Ezisekelwe kubunikazi bobunikazi be-IC Ukufinyelela 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 Ububanzi bufika ku-7936Kbit/s Channel 10M/100M Ethernet interface ingahlukanisa yodwa ukuze ibone ukuxhumana ngokuzimela I-interface ye-Ethernet isekela i-10M/100M, isigamu/egcwele i-duplex ekwazi ukuzivumelanisa nezimo kanye ne-AUTO-MDIX (umugqa oweqa futhi ulayini oxhumeke oqondile ozivumelanisa nezimo ) CRC umkhawulo we-alamu ozenzakalelayo ungasethwa ukuze uhlukanise imigqa yokudlulisela yekhwalithi embi futhi kunqanyulwe indlela eyodwa. Uma izinga lephutha lesifunda segatsha le-2M lidlula umkhawulo, ukunqamula leli cala kolunye uhlangothi akuthinteki; okusho ukuthi, kokubili ukudluliswa kokuqondisa kwe-Ethernet kungaba yi-asymmetric Vumela umehluko wesikhathi sokulibaziseka we-4-Channel 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-timelot E1 enesekhethi yokutakula iwashi eliphakathi-set kanye nesekhethi yekhodi ye-HDB3 Sekela ipulaki eshisayo yesiteshi esingu-E1 kudivayisi, futhi ithola ngokuzenzakalelayo isiteshi se-E1 esisebenzayo futhi ngeke iphazamise ukudluliswa kwedatha Ingasekela 1-4Channel E1 ukucushwa kwesiteshi, 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(10/100M) Izinga le-Interface: 10/100 Mbps, uhhafu/ogcwele i-duplex auto-negotiation Interface Standard: Ihambisana ne-IEEE 802. , IEEE 802.1Q (VLAN) Ikheli le-MAC Amandla: Isixhumi esingu-4096: 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 Umswakama Wesitoreji : 5%~95 % (akukho ukufingqa) Ukucaciswa Inombolo Yemodeli: JHA-CE4F4 Incazelo Esebenzayo I-4E1/4FE interface Converter，Ethernet ingahlukaniswa ngokwehlukana okunengqondo Incazelo Yembobo 4* E1 interface;4 *FE Interface Amandla Amandla Amandla: AC180V ~ 260V；DC -48V;DC +24VPower Ukusetshenziswa: ≤10W Dimension Usayizi Womkhiqizo: Mini uhlobo 216X140X31mm (WXDXH), 1.3KG/piece 19inch 1U uhlobo 483X138X44mm (WXDXH), 2.0KG/ucezu Incazelo yohlelo lokusebenza: Uma idivayisi isetha ukuhlukaniswa okunengqondo, kungafinyelelwa Ukuxhumana okuzimele phakathi kuka-A - A1, B - B1, C - C1 kanye no-D - D1. 1. Iziguquli zephrothokholi zisetshenziswa ngababili; I-2.1-4channel E1 yomugqa wokudlulisa umkhawulokudonsa 1984Kbit / s -7936Kbit / s.

Isingeniso i-JHA-G42 series iyi-10/100/1000M ezishintshayo i-Fast Ethernet fiber switch, enamachweba we-Fiber angu-4 1000M kanye nezixhumi ezibonakalayo ze-Ethernet RJ45 ezingu-2 10/100/1000Base-TX.
