Mbiri yapamwamba Rs485 kupita ku Efaneti - mawonekedwe a E1-FE osinthika JHA-CE1fF1 - JHA

Yopangidwa ndi E1-FE mawonekedwe Converter JHA-CE1fF1

Mwachidule

Chosinthira cholumikizirachi chimakhazikitsidwa ndi FPGA, kupatsa mawonekedwe amodzi a E1 ndi mawonekedwe amodzi a Efaneti kuti akwaniritse kutumiza kwa data 10/100Base-T Ethernet panjira ya E1. Ndi mlatho wapamwamba, wodziphunzira wa Ethernet mlatho. Chipangizochi ndi chipangizo chowonjezera cha Efaneti, chogwiritsa ntchito netiweki (PDH/SDH/Microwave) yomwe imapereka njira ya E1 kuti ikwaniritse kulumikizana kwa Ethernet yam'deralo ndi kutali ndi ma serial interfaces pamtengo wotsika. Chipangizochi chili ndi ntchito yoyeserera ya inter-set loop kuti ithandizire kuyambitsa pulojekiti ndikukonza tsiku ndi tsiku.

Chithunzi cha malonda

Mtundu wa Mini

Mawonekedwe

• Kutengera kudzikonda kwa IC
• Itha kuzindikira kuwunika ndikuwongolera zida zakutali, data yoyang'anira OAM sinatenge nthawi ya ogwiritsa ntchito ndikusunga bandwidth ya E1
• E1 imathandizira nthawi iliyonse, mtengo wake ndi 64K-2048K
• 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;
• 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 (2036 Bytes);
• Inter-set dynamic Ethernet MAC adilesi (4,096) yokhala ndi kusefa kwa data komweko
• Efaneti mawonekedwe amathandiza 10M/100M, theka/full duplex auto- Negotination ndi AUTO-MDIX (wowoloka mzere ndi molunjika mzere wolumikizidwa wekha);
• Khalani ndi Ethernet yowunikira ntchito yodzikonzanso, zida sizidzafa
• Itha kukwaniritsa chipangizo chakutali chokhazikitsa njira iliyonse ya 5 ya Ethernet ndipo imatha kutseka ntchito ya AUTO-MDIX;
• 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),Lamulira kutali
• Efaneti mawonekedwe Loop Back (REM)
• Perekani 2 zolepheretsa: 75 Ohm kusalinganika ndi 120 Ohm balance;
• Thandizani SNMP Network Management;
• Amatha 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)
• Itha kupanga mawonekedwe: Efaneti E1 Bridge (A)－--Optical Ethernet E1 Bridge (B)－--Ethernet Optical Fiber Transceiver (C), imatha kuyendetsa (B) ndi (C) pa (A)
