Mwachidule

Kusintha kwa mawonekedwe awa kumatengera FPGA. Itha kuzindikira kutumiza kwa data kwa 4Channel Ethernet pamayendedwe a 1E1,perekani ogwiritsa ntchito mwayi wa Ethernet pamlingo wa 1984K. Amagwiritsidwa ntchito kwambiri m'madipatimenti azachuma, chitetezo ndi chitetezo omwe amayenera kuperekedwa maukonde awiri osiyana, ndipo onse pamaneti amthupi amatha kupatulidwa kwathunthu. Mwachitsanzo, dongosolo lazachuma la bizinesi, maukonde amkati aofesi ndi maukonde abizinesi sangathe kulumikizidwa palimodzi. Multiplexer iyi imatha kuthetsa vutoli.

Mawonekedwe

• Kutengera kudzikonda kwa IC
• Itha kuzindikira kutumiza kwa data kwa 4Channel Ethernet ndi mabwalo a 1 E1
• Ma Inter-set dynamic Ethernet MAC adilesi (4,096) yokhala ndi ntchito yosefera yam'deralo
• 4Channel Efaneti mlingo ndi 1984Kbps, kukhazikitsa woyamba,chachiwiri,mlingo wachitatu njira, njira yachinayi Efaneti mlingo kugaŵidwa basi
• The chipangizo m'deralo akhoza kukakamiza kutali chipangizo mlingo kutsatira izo
• Khalani ndi ntchito ya E1 mawonekedwe loop kumbuyo cheke, pewani chosinthira chikasokonekera chifukwa cha mawonekedwe a loop kubwerera;
• Itha kukhazikitsa mzere wa E1 kuti usatumize chizindikiro cha LINK ku mawonekedwe a Efaneti pomwe mzere wa E1 wathyoka;
• Mawonekedwe a Ethernet amathandizira mafelemu a jumbo (2036 Bytes)
• Mawonekedwe a Ethernet amathandizira 10M/100M, theka/full duplex auto-Negotiation ndi AUTO-MDIX (mzere wowoloka komanso wolumikizidwa mowongoka wodzisinthira nokha)
• Khalani ndi Ethernet yowunikira ntchito yodzikonzanso, zida sizidzafa
• 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)
• Perekani 2 zolepheretsa: 75 Ohm kusalinganika ndi 120 Ohm balance;
• Kuzindikira kutentha kwa zida zakutali ndi magetsi kuchokera ku zida zakomweko;
• Thandizani SNMP Network Management;
