2019 Ubwino Wabwino Kwambiri Kutembenuza kwa Efaneti - mawonekedwe a Framed E1-V.35 Converter JHA-CE1fV1 - JHA

Yopangidwa ndi E1-V.35 mawonekedwe ConverterJHA-CE1fV1

Mwachidule

Izi chosinthira mawonekedwe amapereka E1 mawonekedwe ndi chimodzi V.35 mawonekedwe akwaniritse mawonekedwe E1 mawonekedwe posamutsa V.35 mawonekedwe. Mtengo wa njira ya data ndi 2.048Mbps. 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
• Khalani ndi chizindikiro pamene chipangizocho chikuzimitsa kapena mzere wa E1 wathyoka kapena kutaya chizindikiro;
• Chipangizo chakomweko chikhoza kukakamiza kuchuluka kwa chipangizo chakutali kuchitsatira (chovomerezeka chikapangidwa)
• Ma hardware amazindikira nthawi iliyonse ya 31 nthawi iliyonse yomwe mungasankhe (yovomerezeka ikapangidwa)
• Perekani 2 zolepheretsa: 75 Ohm kusalinganika ndi 120 Ohm balance;
• Pambuyo poyeserera mwamphamvu ndi dongosolo lotsimikizira, tsatirani kwathunthu protocol ITU-T V.35, G.703, G.704
• Khalani ndi njira zitatu za Loop Back: E1 mawonekedwe Loop Back (ANA),V.35 mawonekedwe Loop Back(DIG),Lamulani mawonekedwe akutali a V.35 Loop Back(REM)
• Khalani ndi pseudo code random test test, mizere yotseguka mosavuta, ingagwiritsidwe ntchito ngati 2M BER Tester
• V.35 mawonekedwe amathandiza otentha pulagi, amathandiza DTE kapena DCE chipangizo cholumikizira
• Perekani mitundu ya wotchi 3: Wotchi yamkati, wotchi yakunja, wotchi ya E1;
• AC 220V, DC-48V, DC+24V, DC Mphamvu ndi Polarity-Free
