E1-FE mea hoʻololi hoʻololi JHA-CE1fF1

Nānā nui

Hoʻokumu ʻia kēia mea hoʻololi hoʻololi ma FPGA, e hāʻawi ana i hoʻokahi kikowaena E1 i hoʻopaʻa ʻia a me hoʻokahi interface Ethernet e hoʻokō ai i ka hoʻoili ʻikepili 10/100Base-T Ethernet ma ke kahawai E1. He hana kiʻekiʻe, aʻo ponoʻī Ethernet alahaka. ʻO kēia hāmeʻa ka mea hoʻonui o Ethernet, me ka hoʻohana ʻana i ka pūnaewele (PDH/SDH/Microwave) e hāʻawi ana i ke ala E1 e hoʻokō ai i ka Ethernet kūloko a mamao hoʻi e pili ana me nā interface serial ma ke kumu kūʻai haʻahaʻa. Loaʻa i ka hāmeʻa ka hana hoʻāʻo loop inter-set e hoʻomaʻamaʻa i ka hoʻomaka ʻana o ka papahana a me ka mālama ʻana i kēlā me kēia lā.
