Nchịkọta

Ihe ntụgharị ihu igwe a dabere na FPGA, na-eji teknụzụ ntụgharị ntụgharị ntụgharị ihu iji chịkọta ọtụtụ sekit E1 iji bufee data Ethernet nke 100BASE-TX. Ọ nwere ike na-aghọta 1-8E1 ọwa iji tọghata n'etiti Ethernet ngwa anya interface. Ngwaọrụ a nwere ike ibunye ebe mgbama transceiver ka ọ rụtụ aka na interface optical Ethernet iji mee ka ọwa E1 jikọọ na interface interface Ethernet. Dị iche na izugbe nke netwọk dịpụrụ adịpụ, ngwaọrụ a nwere ike ịkwado nhazi ọwa 1-8Channel E1, nwere ike chọpụta ọnụọgụ E1 ozugbo wee họrọ E1 dị. Ọ na-enye ohere E1 ahịrị nnyefe oge igbu oge dị iche. igbu oge dị iche.
