Ntụgharị interface E1-2FEJHA-CE1fF2p

(Ọkpụkpọ anụ ahụ)

Nchịkọta

Ihe ntụgharị interface a dabere na FPGA. Multiplex 10/100Base-T Ethernet 2Channel interface na interface E1 iji nye ndị ọrụ ohere Ethernet na ọnụego 1984K. A na-ejikarị ya eme ihe na ego, nchekwa na ngalaba nchekwa nke kwesịrị ịnye netwọk abụọ dị iche iche, ma na netwọk anụ ahụ nwere ike kewaa kpamkpam. Dịka ọmụmaatụ, netwọk azụmahịa nke usoro ego, netwọk ụlọ ọrụ na netwọk azụmahịa enweghị ike ijikọ ọnụ. Nke a interface multiplexer nwere ike dozie nsogbu a.
