4E1-1FE interface Shandurudza JHA-CE4F1 Overview Ichi chinoshandura chinoshandura chakavakirwa paFPGA, chichishandisa reverse direction multiplexing tekinoroji kuunganidza akawanda E1 maseketi kufambisa data reEthernet re4Channel 100BASE-TX. Inogona kuona 1 ~ 4 E1 chiteshi chekushandura pakati peEthernet optical interface. Chishandiso ichi chinogona kufambisa chiratidzo chetransceiver kunongedza kuEthernet optical interface kuita E1 chiteshi chakabatana neEthernet optical interface. Kusiyana neremote kure network bhiriji, chishandiso ichi chinogona kutsigira 1-4Channel E1 chiteshi gadziriso, inogona kuona otomatiki nhamba yeE1 uye sarudza E1 iripo. Inobvumira E1 mitsetse yekufambisa nguva yekunonoka musiyano. Chigadzirwa Photo Mini Type 19 Inch 1U Type Zvimiro Zvichienderana nekuzvimiririra IC Kuti uwane Ethernet data yakajeka kutapurirana mumaseketi 1-4E1 Unogona kuona yemuno uye iri kure mudziyo reset Ethernet Interface ndeye 100BASE-FX, inotsigira VLAN protocol Inter-set dynamic Ethernet. MAC kero (4,096) ine yemuno data furemu kusefa basa Single Channel mitsetse chiyero ndeye 1984Kbit/s, 4Channel. Bandwidth inosvika 7936Kbit/s Tsigira ese seti yeEthernet Work Mode CRC otomatiki alarm pachikumbaridzo inogona kusetwa kuti iparadzanise hurombo hwemhando yekutapurirana mitsara uye kudimburira-imwe nzira. Kana 2M yebazi redunhu imwe yekukanganisa chiyero ichidarika chikumbaridzo, kucheka nzira iyi imwe nzira haina kukanganiswa; kureva kuti, ese ari maviri eEthernet nzira kutapurirana anogona asymmetric Bvumira 4Channel E1 kutapurirana nguva kunonoka musiyano 100ms. Kana iyo margin ichipfuura iyo inobvumidzwa, iyo system inogona kungoerekana yamira paE1 iyo nguva kunonoka yakakura kwazvo kutumira data E1 interface inoenderana neITU-T G.703, G.704 uye G.823, isingatsigire kushandiswa kwechiratidzo. timeslot E1 interface module ine inter-set wachi kudzoreredza dunhu uye HDB3 kodhi kodhi Tsigira E1 chiteshi chinopisa-plug mumudziyo, uye inoona otomatiki chiteshi chinoshanda uye haizokanganisa kufambisa kwedata Inogona kutsigira 1-4Channel. E1 chiteshi gadziriso, inogona kuona otomatiki nhamba yeE1 uye sarudza iyo E1 iripo; Parameters ♦ E1 Interface Interface Standard: teerera mitemo G.703; Interface Rate: n * 64Kbps ± 50ppm; Interface Code: HDB3; E1 Impedance: 75Ω (kusagadzikana), 120Ω (chiyero); Jitter tolerance: Mukuwirirana neprotocol G.742 neG.823 Inobvumirwa Kutarisa: 0~6dBm ♦ Ethernet interface(100/100M) Interface rate: 10/100 Mbps, hafu/full duplex auto-negotiation Interface Standard: Inowirirana neIEEE 802. , IEEE 802.1Q (VLAN) MAC Kero Kugona: 4096 Connector: RJ45, inotsigira Auto-MDIX ♦ Nzvimbo yekushanda Kushanda tembiricha: -10°C ~ 50°C Kushanda Humidity: 5%~95 % (hapana condensation) Kuchengetedza tembiricha: -40°C ~ 80°C Kuchengeta Humidity: 5% ~ 95 % (hapana condensation) Zvinotsanangurwa Modhi Model Nhamba: JHA-CE4F1 Tsanangudzo Yekushanda Kushandisa Kugadzirisa mhinduro 1 Yakajairika mhinduro 2
