8E1-1FE mawonekedwe a JHA-CE8F1

Mwachidule

Kusintha kwa mawonekedwewa kumakhazikitsidwa ndi FPGA, pogwiritsa ntchito ukadaulo wa reverse direction multiplexing kuti mulunjike mabwalo angapo a E1 kuti atumize data ya Ethernet ya 100BASE-TX.Itha kuzindikira njira ya 1-8E1 kuti isinthe pakati pa mawonekedwe a Ethernet.Chipangizochi chikhoza kutumiza chizindikiro cha transceiver kuti chiloze ku mawonekedwe a Efaneti kuti apange njira za E1 zolumikizidwa ndi mawonekedwe a Ethernet optical.Mosiyana ndi mlatho wakutali wakutali, chipangizochi chimatha kuthandizira kasinthidwe ka 1-8Channel E1, imatha kuzindikira nambala ya E1 ndikusankha E1 yomwe ilipo.Iwo amalola E1 mizere kufala nthawi kuchedwa kusiyana.kusiyana kwachedwetsa.

Mawonekedwe

• Kutengera kudzikonda kwa IC
• Kukwaniritsa Efaneti deta mandala kufala mu 1-8E1 mabwalo
• Itha kuzindikira zakukhazikitsanso chipangizo chakutali komanso chakutali
• Ethernet Interface ndi 100BASE-FX, imathandizira protocol ya VLAN
• Ma Inter-set dynamic Ethernet MAC adilesi (4,096) yokhala ndi ntchito yosefera yam'deralo
• Single Channel mizere mizere ndi 1984Kbit/s, 4Channel Bandwidth mpaka 7936Kbit/s
• Thandizani ma seti onse a Ethernet Work Mode
• CRC automatic alarm threshold imatha kukhazikitsidwa kuti isiyanitse mizere yopatsirana yabwino ndikudula njira imodzi.Pamene nthambi ya 2M yozungulira gawo limodzi lolakwika likupitilira malire, kudula mbali iyi sikukhudzidwa;ndiko kunena kuti, ma transmission onse a Ethernetdirection amatha kukhala asymmetric
• Lolani 8Channel E1 kufala nthawi kuchedwa kusiyana 100ms.Pamene malire adutsa malire ololedwa, makinawo amatha kuyimitsa pa E1 kuti kuchedwa kwa nthawi kumakhala kwakukulu kwambiri kuti atumize deta
• Mawonekedwe a E1 amagwirizana ndi ITU-T G.703, G.704 ndi G.823, osachirikiza kugwiritsa ntchito chizindikiro chanthawi
• E1 mawonekedwe gawo ndi inter-set wotchi kuchira dera ndi HDB3 code dera
• Thandizani njira yotentha ya E1 pazida, ndikuzindikira zokha zomwe zimagwira
• njira ndipo sizidzasokoneza kutumiza kwa data
• Itha kuthandizira kasinthidwe ka 1-8Channel E1, imatha kuzindikira nambala ya E1 ndikusankha E1 yomwe ilipo;
