Txheej txheem cej luam

Lub interface converter no yog raws li FPGA, siv cov kev taw qhia rov qab multiplexing thev naus laus zis los ntim rau ntau E1 circuits kom xa cov ntaub ntawv Ethernet ntawm 4Channel 100BASE-TX. Nws tuaj yeem paub 1 ~ 4 E1 channel los hloov ntawm Ethernet optical interface. Cov cuab yeej no tuaj yeem xa cov teeb liab transceiver taw tes rau Ethernet optical interface los ua E1 channels cuam tshuam nrog Ethernet optical interface. Tsis zoo li cov chaw taws teeb network txuas ntxiv, cov cuab yeej no tuaj yeem txhawb nqa 1-4Channel E1 channel teeb tsa, tuaj yeem ntes tus lej E1 thiab xaiv E1 muaj. Nws tso cai rau E1 kab kis tau tus mob ncua sij hawm sib txawv.

• Raws li tus kheej-copyright IC
• Txhawm rau ua tiav Ethernet cov ntaub ntawv pob tshab sib kis hauv 1-4E1 circuits
• Yuav paub txog lub zos thiab cov chaw taws teeb reset
• Ethernet Interface yog 100BASE-FX, txhawb VLAN raws tu qauv
• Inter-set dynamic Ethernet MAC chaw nyob (4,096) nrog cov ntaub ntawv hauv zos thav duab lim dej muaj nuj nqi
• Ib kab kab tus nqi yog 1984Kbit / s, 4Channel Bandwidth yog mus txog 7936Kbit / s
• Channel 10M / 100M Ethernet interface tuaj yeem cais ib leeg kom paub txog kev sib txuas lus ntawm nws tus kheej
• Ethernet interface txhawb nqa 10M / 100M, ib nrab / tag nrho duplex auto-adaptable thiab AUTO-MDIX (hloov kab thiab ncaj nraim txuas kab nws tus kheej-adaptable)
• CRC lub tswb tsis siv neeg lub tswb tuaj yeem teeb tsa kom cais cov kab tsis zoo sib kis thiab txiav tawm ib qho kev taw qhia. Thaum 2M ceg Circuit Court ib qho kev ua yuam kev tus nqi siab tshaj qhov pib, txiav tawm qhov kev taw qhia rau lwm qhov kev taw qhia tsis cuam tshuam; uas yog hais, ob qho tib si ntawm Ethernet directiontransmission tuaj yeem ua asymmetric
• Tso cai 4-Channel E1 kis tau tus mob ncua sij hawm sib txawv 100ms. Thaum cov paj laum tshaj qhov kev tso cai, lub kaw lus tuaj yeem nres ntawm E1 tias lub sijhawm ncua sijhawm loj dhau los xa cov ntaub ntawv
• E1 interface ua raws li ITU-T G.703, G.704 thiab G.823, tsis txhawb kev siv lub sijhawm teeb tsa
• E1 interface module nrog inter-set moos rov qab Circuit Court thiab HDB3 code Circuit Court
• Kev them nyiaj yug E1 channel hot-plug nyob rau hauv lub cuab yeej, thiab txiav txim siab qhov zoo E1 channel thiab yuav tsis cuam tshuam cov ntaub ntawv xa mus.
• Txhawb nqa 1-4Channel E1 channel configuration, tuaj yeem ntes tus naj npawb ntawm E1 thiab xaiv E1 muaj;
