E1-4FE mea hoʻololi hoʻololiJHA-CE1fF4

Nānā nui

Hoʻokumu ʻia ka mea hoʻololi hoʻololi E1-4ETH ma FPGA. Hāʻawi ka hāmeʻa i ka hoʻololi ma waena o ITU-T G.703 (E1) maʻamau i hoʻonohonoho ʻia ʻo E1 interface a me 10/100Base-T interface. ʻO kahi alahaka Ethernet lōʻihi lōʻihi hiki ke hoʻololi iā ia iho. He liʻiliʻi a haʻahaʻa ka huahana. Hoʻohana nui ʻia i ka hoʻopili ʻana ma waena o WAN a me LAN, nānā, etc

• Ma muli o ka IC pono'ī
• Kākoʻo ʻo E1 i kēlā me kēia hoʻonohonoho timeslot, ʻo ka helu he 64K-2048K
• 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 ka mea hoʻohana a mālama i ka bandwidth E1
• Loaʻa i ka hana o E1 interface loop back check, e pale aku i ka mea hoʻololi i hāʻule ma muli o ka hoʻihoʻi ʻana o ka loop interface; Loaʻa i ka hōʻailona ke pio ka mana a i ʻole
• Ua haki a nalowale ka laina E1;
• Hiki iā ʻoe 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 nānā pono ʻana i ka hana, 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 nā helu helu hewa.
• Hoʻomaopopo i ka nānā ʻana i ka wela o nā lako mamao a me ka volta mai nā lako kūloko;
• Kākoʻo SNMP Network Management;
• Hiki ke hana i ka hale: Ethernet E1 Bridge(A)----E1 Optical Fiber Modem(B)----Ethernet Optical Fiber Modem (C)
