4E1-4FE Kaitahuri Atanga JHA-CE4F4 (Taumaha arorau)

Tirohanga

Ko tenei kaitahuri atanga kei runga i te FPGA, ma te whakamahi i te hangarau whakamuri whakamuri maha ki te paihere mo nga iahiko E1 maha hei tuku i nga raraunga Itarangi o 4Channel 100BASE-TX.Ka taea e mohio te reira 1 ~ 4 E1 hongere ki te tahuri i waenganui i Itarangi atanga whatu.Ka taea e tenei taputapu te tuku i te tohu tohu whakawhiti ki te tohu ki te atanga whatu Itarangi kia hono nga awa E1 ki te atanga whatu Itarangi.Kaore i rite ki te piriti whatunga mamao whanui, ka taea e tenei taputapu te tautoko i te whirihoranga hongere 1-4Channel E1, ka taea te kite aunoa i te maha o E1 me te kowhiri i te E1 e waatea ana.Ka taea e nga raina E1 te rereketanga o te wa whakaroa.

Ngā āhuatanga

• I runga i te mana-whaiaro IC
• Hei whakatutuki i nga raraunga Itarangi te whakawhiti maramara i roto i nga iahiko 1-4E1
• Ka taea te mohio ki te tautuhi i te rohe me te taputapu mamao
• Ko te Atanga Itarangi ko 100BASE-FX, tautoko kawa VLAN
• Wāhitau Ethernet MAC hihiri (4,096) me te mahi tātari anga raraunga rohe
• He 1984Kbit/s te reiti o nga raina Hoera kotahi, 4Channel Aratuku kei te 7936Kbit/s
• Ka taea e te hongere 10M/100M te atanga Ethernet te wehe tetahi ki tetahi ki te mohio ki te whakawhitiwhiti korero takitahi
• Tautoko atanga Itarangi10M/100M, haurua/katoa matarua-aunoa ka urutau me te AUTO-MDIX (raina whakawhiti me te raina hono tika ka taea te urutau-whaiaro)
• Ka taea te tautuhi i te paepae whakaoho aunoa a CRC ki te wehe i nga raina tuku kounga kino me te tapahi i te huarahi kotahi.I te wa e neke atu ai te 2M peka i te reeti hapa kotahi te ahunga, ka tapahia tenei ahunga kaore e pa atu tetahi atu huarahi;ara, ka taea e rua o te whakawhiti aronga Ethernet te hangarite
• Whakaaetia te 4-Channel E1 te rereketanga o te wa whakaroa 100ms.Ka nui ake te tawhē i te awhe e whakaaetia ana, ka taea e te punaha te aukati aunoa i te E1 he nui rawa te wa roa ki te tuku raraunga
• Ko te atanga E1 e rite ana ki te ITU-T G.703, G.704 me G.823, kaore i te tautoko i te whakamahi i te waahi tohu tohu.
• Kōwae atanga E1 me te ara iahiko whakaora karaka i waenga me te ara iahiko waehere HDB3
• Tautokohia te hongere E1 wera-mono i roto i te taputapu, ka kitea aunoa i te hongere E1 whai hua, ka kore e haukotia te tuku raraunga
• Ka taea te tautoko i te whirihoranga hongere 1-4Channel E1, ka taea te kite aunoa i te maha o E1 ka kowhiri i te E1 e waatea ana;
