Nchịkọta

Ihe ntụgharị ihe ntụgharị a dabere na FPGA, na-eji teknụzụ ntụgharị ntụgharị ntụgharị ihu iji chịkọta ọtụtụ sekit E1 iji nyefee data Ethernet nke 4Channel 100BASE-TX. Ọ nwere ike na-aghọta 1 ~ 4 E1 ọwa iji tọghata n'etiti Ethernet ngwa anya interface. Ngwaọrụ a nwere ike ibunye ebe mgbama transceiver ka ọ rụtụ aka na interface interface Ethernet iji mee ka ọwa E1 jikọọ na interface interface Ethernet. N'adịghị ka àkwà mmiri netwọk dịpụrụ adịpụ izugbe, ngwaọrụ a nwere ike ịkwado nhazi ọwa 1-4Channel E1, nwere ike chọpụta ọnụọgụ E1 ozugbo wee họrọ E1 dị. Ọ na-enye ohere E1 ahịrị nnyefe oge igbu oge dị iche.

• Dabere na ikike nwebiisinka IC
• Iji nweta nnyefe transperent data Ethernet na sekit 1-4E1
• Nwere ike ịghọta nrụpụta ngwaọrụ mpaghara na nke dịpụrụ adịpụ
• Ethernet Interface bụ 100BASE-FX, nkwado VLAN protocol
• Inter-set dynamic Ethernet MAC adreesị (4,096) nwere ọrụ nzacha data etiti data
• Ọnụọgụ ahịrị otu ọwa bụ 1984Kbit/s, bandwit 4Channel ruru 7936Kbit/s
• Ọwa 10M/100M Ethernet interface nwere ike kewapụ onwe ya iji ghọta nkwurịta okwu n'adabereghị
• Ihe ntanetị Ethernet na-akwado 10M / 100M, ọkara / zuru oke duplex auto- adaptable na AUTO-MDIX (akara gafere na ahịrị ejikọtara nke ọma na-emegharị onwe ya)
• Enwere ike ịtọ ọnụ ụzọ mkpuchi mkpuchi CRC akpaka ka ọ kewapụ ahịrị nnyefe adịghị mma wee bepụ otu ụzọ. Mgbe 2M alaka sekit onedirection ọnụego njehie gafere n'ókè, ebipụ ntụziaka a ọzọ adịghị emetụta; ya bụ, ma nke Ethernet direction transmission nwere ike ịbụ asymmetric
• Kwe ka 4-Channel E1 nnyefe oge igbu oge ọdịiche 100ms. Mgbe oke ahụ gafere oke ekwenyere, sistemụ ahụ nwere ike kwụsị ozugbo na E1 na oge igbu oge buru oke ibu izipu data
• E1 interface kwekọrọ na ITU-T G.703, G.704 na G.823, anaghị akwado iji akara timeslot.
• E1 interface modul nwere inter-set elekere mgbake sekit na HDB3 code sekit
• Na-akwado nkwụnye ọkụ ọkụ E1 ọwa, ma chọpụta ọwa E1 dị irè na-akpaghị aka ma ghara ịkwụsị nnyefe data
• Nwere ike ịkwado nhazi ọwa 1-4Channel E1, nwere ike ịchọpụta ọnụọgụ E1 ozugbo wee họrọ E1 dị;
