Mtengo wotsika mtengo Rs422 kupita ku Efaneti - mawonekedwe a E1-4FE Osasinthika JHA-CE1F4 - JHA

Kusintha kwa mawonekedwe a E1-4FE osasinthika JHA-CE1F4

Mwachidule

Protocol converter (interface converter) yogwiritsa ntchito masikelo akulu a FPGA, ITU-T G.703 yolumikizira E1 yokhazikika komanso inayi 10/100Base-T Efaneti chosinthira, 10/100Base-T njira zitumizidwa ku switch, HUB, rauta. , milatho, kapena chipangizo china. Ndipo kudzera mu Optical ndi zida zina zoyendera zidasamutsidwa, maukonde amatha kupangidwa ndi magawo osiyanasiyana amtaneti. Chipangizochi ndichochita bwino kwambiri, mlatho wakutali wa Ethernet. Kakulidwe kake kakang'ono, kotsika mtengo, koyenera kwambiri pamakina otsika mtengo kapena ngati LAN extender kapena slicer bitstream pazomangamanga. Mutha kuphunzira zokha adilesi ya LAN MAC yolumikizidwa mosalekeza pa adilesi yolowera chimango ndi kutumiza kwina kwa LAN. Pa protocol ya TCP / IP yowonekera, perekani chitetezo pa intaneti yolumikizirana pakati pa zida zosiyanasiyana zamawonekedwe, kulumikizana kopanda msoko. Zida izi zimagwiritsidwa ntchito kwambiri pakati pa WAN ndi LAN networking, munda wowunika

Mawonekedwe

• Kutengera kudzikonda kwa IC
• Itha kuzindikira kuwunika ndikuwongolera zida zakutali, data yoyang'anira OAM sinatenge nthawi ya ogwiritsa ntchito ndikusunga bandwidth ya E1
• Khalani ndi ntchito ya E1 mawonekedwe loop kumbuyo cheke, pewani chosinthira chikasokonekera chifukwa cha mawonekedwe a loop kubwerera;
• Khalani ndi chizindikiro pamene chipangizocho chikuzimitsa kapena mzere wa E1 wathyoka kapena kutaya chizindikiro;
• Itha kukhazikitsa mzere wa E1 kuti usatumize chizindikiro cha LINK ku mawonekedwe a Efaneti pomwe mzere wa E1 wathyoka; Mawonekedwe a Efaneti amathandizira mafelemu a jumbo (1916 Bytes);
• 4Channel 10M/100M Efaneti mawonekedwe akhoza kudzipatula wina ndi mzake kuzindikira kulankhula paokha;
• Mawonekedwe a Efaneti amathandizira10M/100M, theka/full duplex auto-Negotiation ndi AUTO-MDIX (wowoloka mzere ndikulumikizana molunjika wodzisintha);
• Perekani mitundu iwiri ya wotchi: E1 master wotchi ndi E1 mzere wotchi;
• Khalani ndi njira zitatu za Loop Back: E1 mawonekedwe Loop Back (ANA),Efaneti mawonekedwe Loop Back (DIG),Lamulani mawonekedwe akutali a Ethernet Loop Back (REM)
• Khalani ndi pseudo mwachisawawa kuyesa ma code ntchito, zosavuta kukhazikitsa ndi kukonza;
• Perekani 2 zolepheretsa: 75 Ohm kusalinganika ndi 120 Ohm balance;
  Khalani ndi Ethernet yowunikira ntchito yodzikonzanso, zida sizidzafa
• Mawonekedwe a Ethernet amathandizira zowerengera zolandirira ndi kutumiza chimango, amalandila zowerengera zolakwika. E1 mawonekedwe amathandizira zowerengera za kulandira chimango cholakwika;
• Thandizani SNMP Network Management;
• Kuzindikira kutentha kwa zida zakutali ndi magetsi kuchokera ku zida zakomweko;
• Itha kupanga mawonekedwe: Efaneti E1 Bridge (A)----E1 Optical Fiber Modem (B)----Ethernet Optical Fiber Modem (C)
