2019 Mtundu wapamwamba kwambiri Rs232 mpaka Rs485 - Co-Directional 64K-FE Converter JHA-CE1tF1 - JHA

Mwachidule

Mawonekedwe a G.703 (Co-Directional G.703) amagawaniza kuzungulira kwa 64Kbps mu magawo anayi a mayunitsi, amagwiritsa ntchito "0101" kuyimira "0", "1100" kuyimira "1". Mwa kusintha kusintha kwa polarity ya block yoyandikana, ma signature a binary amasintha ma sign atatu. Pagulu lililonse lachisanu ndi chitatu linawononga chipika cha polarity alternating, motero kufalitsa chizindikiro cha 8KHz. Potengera zomwe zili pamwambapa, chizindikiro cha G.703 chogwirizana ndi 64Kbps chitha kutumiza chizindikiro chanthawi ya 64KHz ndi 8KHz ndi 64KHz ndi chizindikiro cha data cha 64Kbit/s mbali imodzi yokhala ndi mzere wokhazikika.
Kusintha kwa mawonekedwewa kumapereka mawonekedwe amodzi a G.703 ndi mawonekedwe amodzi a Efaneti kuti akwaniritse kutumiza kwa data kwa 10/100Base-T Ethernet panjira ya G.703. Ndi mlatho wapamwamba, wodziphunzira wa Ethernet mlatho. Chipangizochi ndi chipangizo chowonjezera cha Efaneti, pogwiritsa ntchito netiweki (PDH/SDH/Microwave) yomwe imapereka njira ya G.703 kuti ikwaniritse kulumikizana kwa Efaneti wapafupi 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
• Mutha Kuzindikira kutumiza kwa data kwa Efaneti mu gawo limodzi la Co-directional G.703
• Inter-set dynamic Ethernet MAC adilesi (4,096) yokhala ndi zosefera zam'deralo
• Chipangizo chapafupi chimatha kuyendetsa chipangizo chakutali
• Khalani ndi ntchito ya G.703 loop back check, ndikuwonetsa pa LED
• Ikhoza kusiyanitsa chifukwa cha Co-directional G.703 kutaya chizindikiro ndi chakuti chipangizo chakutali chozimitsa kapena mzere wa G.703 wosweka wosweka
• Efaneti mawonekedwe amathandiza 10M/100M, theka/full duplex auto- chosinthika, amathandiza VLAN
• Mawonekedwe a Efaneti amathandizira AUTO-MDIX (mzere wowoloka komanso wolumikizidwa molunjika wodzisintha);
• Perekani mitundu ya wotchi ya 2: Co-Directional G.703 master clock ndi G.703 line clock;
• Chipangizo cham'deralo chikhoza kukakamiza kuchuluka kwa chipangizo chakutali kuti chitsatire (chomwe chidacho sichinalembedwe, ndicholakwika)
• Khalani ndi Loop Back Mode itatu: G.703 interface Loop Back (ANA),Efaneti mawonekedwe Loop Back (DIG),Lamulani mawonekedwe akutali a Ethernet Loop Back (REM)
• Thandizani kudzisintha 120 Ohm bwino;
