Mea hoʻololi E1-4FE paʻa ʻole JHA-CE1F4

Nānā nui

Keia protocol converter (interface converter) me ka hoʻohana ʻana i ka hoʻolālā FPGA nui, ITU-T G.703 maʻamau unframed E1 interfaces a me ʻehā 10 / 100Base-T Ethernet interface converter, 10 / 100Base-T nā kahawai e hoʻololi ʻia i ke kuapo, HUB, nā mea ala. , nā alahaka, a i ʻole nā ​​mea hana ʻē aʻe. A ma o Optical a me nā mea lawe kaʻa ʻē aʻe i hoʻoili ʻia, hiki ke haku ʻia ka pūnaewele i nā ʻāpana pūnaewele like ʻole. He hana kiʻekiʻe kēia mea hana, adaptive mamao alahaka Ethernet. ʻO kona liʻiliʻi liʻiliʻi, ke kumu kūʻai haʻahaʻa, kūpono loa no nā noi hoʻopili pili koʻikoʻi a i ʻole ma ke ʻano he LAN extender a i ʻole slicer bitstream ma nā ʻoihana. Hiki iā ʻoe ke aʻo maʻalahi i ka helu LAN MAC pili i ka helu wahi e hele ai o ke kiʻi a me kahi hoʻouna LAN ʻē aʻe. Ma ka TCP / IP protocol transparent, e hāʻawi i ka palekana no ka ʻoihana kamaʻilio ma waena o nā ʻaoʻao ʻokoʻa like ʻole, ka pilina paʻa ʻole. Hoʻohana nui ʻia kēia mea hana ma waena o WAN a me LAN networking, kiaʻi kahua

• Ma muli o ka IC pono'ī
• Hiki ke hoʻomaopopo i ka nānā ʻana a me ka mālama ʻana i nā lako mamao, ʻaʻole i lawe ka ʻikepili hoʻokele OAM i ka manawa o nā mea hoʻohana a mālama i ka bandwidth E1
• Loaʻa i ka hana o ka E1 interface loop back check, e pale aku i ka converter crashed no ka hoʻi ʻana o ka loop loop;
• Loaʻa ka hōʻailona i ka wā e pau ai ka mana a i ʻole ka laina E1 i haki a nalowale paha i ka hōʻailona;
• Hiki iā ia ke hoʻonohonoho i ka laina E1 e hoʻouna ʻole i ka hōʻailona LINK i ka interface Ethernet i ka wā e haki ai ka laina E1; Kākoʻo ke kikowaena Ethernet i nā papa jumbo (1916 Bytes);
• 4Channel 10M/100M Ethernet interface hiki ke hoʻokaʻawale i kekahi i kekahi e ʻike i ke kamaʻilio kūʻokoʻa;
• Kākoʻo ʻo Ethernet i ka 10M/100M, hapalua/full duplex auto-Negotiation a me AUTO-MDIX (laina kea a me ka laina pili pololei i hiki ke hoʻololi iā ia iho);
• Hāʻawi i 2 mau ʻano uaki: E1 master clock a me E1 line clock;
• Loaʻa i ʻekolu ʻano Loop Back: E1 interface Loop Back (ANA)、Pilikia Ethernet Loop Back(DIG)、Kauoha i ke kikowaena Ethernet mamao Loop Back (REM)
• Loaʻa i ka hana hoʻāʻo pseudo random code, maʻalahi ka hoʻonohonoho ʻana a me ka mālama ʻana;
• Hāʻawi i 2 impedances: 75 Ohm unbalance a me 120 Ohm kaulike;
  Loaʻa iā Ethernet ka hana hoʻoponopono hou iā ia iho, ʻaʻole e make nā mea hana
• Kākoʻo ʻo Ethernet i nā helu helu o ka loaʻa ʻana a me ka hoʻouna ʻana i ke kiʻi, loaʻa i nā helu kuhi hewa. Kākoʻo ʻo E1 i nā helu helu no ka loaʻa ʻana o ke kiʻi hewa;
• Kākoʻo SNMP Network Management;
• Hoʻomaopopo i ka nānā ʻana i ka wela o nā lako mamao a me ka volta mai nā lako kūloko;
• Hiki ke hana i ka hale: Ethernet E1 Bridge(A)－－-E1 Optical Fiber Modem (B)－－-Ethernet Optical Fiber Modem (C)
