2019 Mtundu wapamwamba kwambiri Rs232 mpaka Rs485 - mawonekedwe a E1-4FE mawonekedwe JHA-CE1fF4 - JHA

Yopangidwa ndi E1-4FE mawonekedwe ConverterJHA-CE1fF4

Mwachidule

E1-4ETH mawonekedwe osinthira amachokera ku FPGA. Chipangizochi chimapereka kusintha pakati pa mawonekedwe a ITU-T G.703 (E1) opangidwa ndi E1 ndi mawonekedwe a 10/100Base-T. Ndi mlatho wapamwamba kwambiri, wodzisinthira pawokha mtunda wautali wa Ethernet. Mankhwalawa ndi ochepa komanso otsika mtengo. Amagwiritsidwa ntchito kwambiri polumikizana pakati pa WAN ndi LAN, kuyang'anira, etc

Chithunzi cha malonda

Mtundu wa Mini

Mawonekedwe

• Kutengera kudzikonda kwa IC
• E1 imathandizira nthawi iliyonse, mtengo wake ndi 64K-2048K
• 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;
• Efaneti mawonekedwe amathandiza 10M/100M, theka/full duplex auto-Negotiation ndi AUTO-MDIX (wowoloka mzere ndi molunjika mzere wolumikizidwa kudzisintha);
• 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 Efaneti amathandiza zowerengera zolandirira ndi kutumiza chimango, zimalandira zowerengera zolakwika.
• Kuzindikira kutentha kwa zida zakutali ndi magetsi kuchokera ku zida zakomweko;
• Thandizani SNMP Network Management;
• Itha kupanga mawonekedwe: Efaneti E1 Bridge (A)－--E1 Optical Fiber Modem (B)－--Ethernet Optical Fiber Modem (C)
