Nānā nui

Hoʻokumu ʻia kēia mea hoʻololi interface ma FPGA.Hiki ke hoʻomaopopo i ka hoʻoili ʻikepili 4Channel Ethernet ma luna o 1E1 kaapuni，hāʻawi i nā mea hoʻohana me ka Ethernet komo ma ka helu o 1984K.Hoʻohana nui ʻia ia i nā keʻena kālā, nā palekana a me nā keʻena palekana e pono e hoʻolako ʻia i ʻelua mau pūnaewele ʻokoʻa, a hiki ke hoʻokaʻawale loa ʻia nā mea ʻelua ma kahi pūnaewele kino.No ka laʻana, ʻaʻole hiki ke hoʻopili ʻia ka ʻoihana ʻoihana ʻoihana kālā, ka ʻoihana kūloko a me ka ʻoihana ʻoihana.Hiki i kēia multiplexer interface ke hoʻoponopono i kēia pilikia.

• Ma muli o ka IC pono'ī
• Hiki ke hoʻomaopopo i ka lawe ʻana i ka ʻikepili 4Channel Ethernet e 1 E1 kaapuni
• Inter-set dynamic Ethernet MAC address (4,096) me ka hana kānana ʻikepili kūloko
• ʻO 4Channel Ethernet rate he 1984Kbps, hoʻonohonoho i ka mua，ka lua，ʻO ke kahawai ʻekolu, ʻo ka haʻahaʻa o ka laina Ethernet hoʻokaʻawale ʻokoʻa
• Hiki i ka mea kūloko ke hoʻoikaika i ka helu kelepona mamao e hahai iā ia
• 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;
• 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 (2036 Bytes)
• Kākoʻo ʻo Ethernet i ka 10M/100M, hapalua/full duplex auto-Negotiation a me AUTO-MDIX (laina kea a me ka laina pili pololei hiki ke hoʻololi iā ia iho)
• Loaʻa iā Ethernet ka hana hoʻoponopono hou iā ia iho, ʻaʻole e make nā mea hana
• 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)
• Hāʻawi i 2 impedances: 75 Ohm unbalance a me 120 Ohm kaulike;
• Hoʻomaopopo i ka nānā ʻana i ka wela o nā lako mamao a me ka volta mai nā lako kūloko;
• Kākoʻo SNMP Network Management;

♦E1 Interface

Kūlana Interface: hoʻokō me ka protocol G.703;
Ka helu o ka Interface: n*64Kbps±50ppm;
Code Interface: HDB3;

E1 Impedance: 75Ω (ke kaulikeʻole), 120Ω (kaulike);

ʻO ka hoʻomanawanui Jitter: E like me ka protocol G.742 a me G.823

ʻAe ʻia ka Attenuation: 0~6dBm

♦Pākuʻi Ethernet(10/100M)

Laki waena: 10/100 Mbps, ka hapalua/ piha duplex auto-negotiation

Kūlana Interface: Kūpono me IEEE 802.3, IEEE 802.1Q (VLAN)

Hiki iā MAC Address: 4096

Mea hoʻohui: RJ45, kākoʻo Auto-MDIX

♦Kaiapuni hana

Ka wela hana: -10°C ~ 50°C

Ka haʻahaʻa hana: 5% ~ 95 % (ʻaʻohe condensation)

Ka mahana mālama: -40°C ~ 80°C

Waihona haʻahaʻa: 5%~95 % (ʻaʻohe condensation)
