Tirohanga

Ko te taputapu e whakamahi ana i te hangarau whakamuri whakamuri maha hei paihere mo te E1 maha hei tuku i nga raraunga Itarangi o 3Channel 1000BASE-TX me 2x1000Base-X. Ka taea e mohio te reira 1~16 E1 tahuri i waenganui i Itarangi atanga whatu, ki te hanga E1 takere interconnected ki Itarangi atanga whatu. Ma te whakamahi i te GFP encapsulation, tautoko i te LCAS (te kaupapa whakatikatika kaha hono) me te kawa LAPS. Ka taea e tenei taputapu te tautoko i te whirihoranga hongere 1-16Channel E1, ka taea te kite aunoa i te maha o E1 ka kowhiri i te E1 e waatea ana. Ka taea e ia te wa tuku raina E1, ko te reiti raina kotahi ko 1984Kbit/s, 4channe Itarangi bandwidth ko 7936Kbit/s, 8channel bandwidth ko 15872 Kbit/s, 16channel bandwidth ka taea te 31744Kbit/s.
Ka whakaratohia e te taputapu te mahi whakaoho. Ko te mahi he pono, he pumau, he iti te kaha o te kaha, te whakauru nui, te rahi iti. Tautokohia te whakahaere Whatunga SNMP.

Ngā āhuatanga

• Ko te whakawhiti marama o nga raraunga Ethernet i roto i te 1 ki te 16 E1 iahiko;
• Ka taea te whakauru ki te atanga hiko whakawhiti Itarangi e rima mo te kaiwhakamahi ki te whakaora i te whakawhiti Itarangi;
• 1000Base-TX Tautoko 10/100/1000M, ki tonu/hawhe matarua tino urutau, tautoko kawa VLAN;
• Ka tautoko ia tauranga i te tautoko Ethernet AUTO-MDIX (taura whakawhiti me te urutau raina-tika);
• 16-channel E1 nga rarangi, ko te rereketanga o te roanga roa i waenga i nga mea e rua ka tae ki te 220ms; ka rereke te roa o te 220ms, ko te whakaroa ka puta he whakaoho ohorere, i te wa e raru ana te pakihi;
• I hangaia te rarangi wahitau MAC Ethernet hihiri (4096), me te mahi tātari anga raraunga rohe;
• Ko te atanga E1 e tutuki ana ki te ITU-T G.703, G.704 me G.823, kaua e tautoko i te whakamahinga o nga waahi tohu tohu;
• Ko te aratau taima, ko te waa rohe whiriwhiri me te whai i te waa raina E1, ka taea te huri aunoa i te puna wa raina E1 kia rite ki te kounga tohu. Pērā i te pūnaha puna wā rārangi E1 mo te Rori tuatahi E1, i te korenga o te E1 tuatahi (whakatupato nui a LOS / AIS / LOF / CRC4 me te whakaputa tohu whakamuri) me te ara tuarua E1 kei te mahi tika, ka huri aunoa te punaha ki te ara. Ko te huarahi tuarua E1; te whakakore i te he, ka hoki aunoa te punaha ki te ara tuatahi o te huarahi E1;
• Te tautukunga ki te kawa paerewa ITU-T, GFP-F encapsulation suggestion G.7041, VCAT virtual concatenation and LCAS Link Capacity Adjustment recommendation G.7042, Ethernet mapping to nxE1 recommendation G.7043, Ethernet to single E1 map suggestion G. 8040;
• Ka piki ake te bandwidth tuku, kaore e pakaru nga raraunga Ethernet; Ka whakahekehia te bandwidth tuku, ka taea hoki te mohio me te kore e pakaru te whatunga raraunga Ethernet;
• Ko nga pito o te awa Ø e kore pea e rite ki te hononga rangatū;
• Ki te rahua tetahi aronga paheke E1, ka mahi tonu tera atu aronga;
• Whakamuri tohu tohu E1 ka tapahia te mahi rapu aunoa: I te wa e kitea ana te puta mai o te rori tohu tohu E1, ka tapahia e te punaha tenei E1; I tukuna te loopback, E1 whakaora aunoa i tenei huarahi;
• Whakaotia te tohu whakaoho, whiriwhiri ki te whakaatu i te whakaoho o te rohe / mamao;
• Ka tautokohia te mahi whakahuri taha taha taha E1 kia pai ai te whakamatautau i nga raina E1;
• Tautokohia te punaha rohe mo te tautuhi i te punaha mamao;
• whakarato atanga mamao whakahau loopback, ngāwari ki te tiaki raina;
• Ko te atanga whakahaere papatohu e whakarato ana mo te whakatuwheratanga ngawari;
• Whirihoranga kōwae whakahaere whatunga, tautoko motuhake SNMP whakahaere whatunga;
• ki tenei mutunga i roto i te tirohanga i te mana mahi o te mahi whakaatu pūrere mamao;
• He maha nga whiringa aratau mana: AC220V, DC-48V / DC24V me etahi atu;
• DC-48V / DC24V toha hiko me te mahi kitenga polarity aunoa, ka whakauruhia kaore he rereketanga i waenga i te pai me te kino.
