Nānā nui

Hoʻokaʻawale ka G.703 (Co-Directional G.703) i ka pōʻaiapuni 64Kbps i 4 mau kikowaena, hoʻohana ʻo ia i ka "0101" e hōʻike ana i ka "0", "1100" e hōʻike ana i ka "1". Ma ka hoʻololi ʻana i ka polarity o ka poloka pili, hoʻololi nā hōʻailona binary i nā hōʻailona pae ʻekolu. I kēlā me kēia hui 8 i luku ʻia ka poloka o ka polarity ʻokoʻa, no laila e hoʻouna i ka hōʻailona manawa 8KHz. Ma ka coding i luna, hiki i ka G.703 co-directional 64Kbps hōʻailona ke hoʻokō i ka hoʻouna ʻana i ka hōʻailona manawa o 64KHz a me 8KHz a me 64KHz a me ka hōʻailona ʻikepili o 64Kbit/s ma ka ʻaoʻao like me kahi laina kaulike pālua.
Hāʻawi kēia mea hoʻololi hoʻololi i hoʻokahi interface G.703 co-directional a me hoʻokahi interface Ethernet e hoʻokō i ka hoʻouna ʻikepili 10/100Base-T Ethernet ma ke kahawai G.703. 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 i ke ala G.703 e hoʻokō ai i ka Ethernet kūloko a me ka mamao 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.
