Taunga Hou Haina Rs232 Ki te 485 Kaitahuri - 8E1-1FE atanga Kaihuri JHA-CE8F1 – JHA

Tirohanga

Ko tenei kaitahuri atanga kei runga i te FPGA, ma te whakamahi i te hangarau whakamuri whakamuri multiplexing ki te paihere mo nga iahiko E1 maha hei tuku i nga raraunga Ethernet o 100BASE-TX. Ka taea e ia te mohio ki te hongere 1-8E1 ki te huri i waenga i te atanga whatu Itarangi. 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 Ethernet. He rereke ki te piriti whatunga mamao whanui, ka taea e tenei taputapu te tautoko i te whirihoranga hongere 1-8Channel 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. rerekētanga whakaroa.

Ngā āhuatanga

• I runga i te mana-whaiaro IC
• Hei whakatutuki i nga raraunga Itarangi te whakawhiti maramara i roto i nga iahiko 1-8E1
• 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
• Tautokohia nga huinga katoa o te Aratau Mahi Ethernet
• Ka taea te tautuhi i te paepae whakaoho aunoa CRC ki te wehe i nga raina tuku kounga kino me te tapahi i te huarahi kotahi. Ina 2M te ara iahiko peka kotahi te reiti hapa o te ahunga ka nui ake i te paepae, ka tapahia tenei ahunga kaore e pa ki tera atu huarahi; ara, ka taea e rua o te tuku Ethernetdirection te hangarite
• Tukua kia 8Channel 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 whakamahinga o te waahi tohu tohu.
• Kōwae atanga E1 me te ara iahiko whakaora karaka i waenga me te ara iahiko waehere HDB3
• Tautoko E1 hongere wera-mono i roto i te taputapu, a ka kitea aunoa i te whai hua
• hongere me te kore e haukotia te tuku raraunga
• Ka taea te tautoko i te whirihoranga hongere 1-8Channel E1, ka taea te kite aunoa i te maha o E1 ka kowhiri i te E1 e waatea ana;
