2019 Mea hoʻololi Serial maikaʻi i Ethernet - Hoʻololi Hoʻohui 64K JHA-CE1tV1 – JHA

Mea hoʻololi hui 64K-V.35JHA-CE1tV1

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.
64k-V.35 / V.24 mīkini hoʻololi hāʻawi ITU-T co-64K G.703 maʻamau E1 interface a me ka maʻamau V.35 huli ana ma waena o ka physical papa / V.24. Pūnaewele e hāʻawi i nā kamaʻilio paʻa ma waena o nā polokalamu o nā ʻokoʻa like ʻole, ka pilina paʻa ʻole. E pili ana ka pauku kanal E1 i ka hoʻouna ʻana i nā lako lako i loaʻa, a me ka pono e hoʻololi i ka ʻikepili i ka V35 / V24 wale nō ka hoʻokuʻu ʻana o ka hanana, ʻo DCE ka mode interface data, me DTE a i ʻole DCE.

Nā hiʻohiʻona

• Ma muli o ka IC pono'ī;
• Hāʻawi i 2 ʻano uaki: Co-Directional G.703 master clock a me G.703 line clock;
• Loaʻa i ʻelua Loop Back Mode: G.703 interface Loop Back , V.35 interface Loop Back;
• Loaʻa i ka pseudo random code test function, maʻalahi no ka hoʻokomo;
• Kākoʻo 120 Ohm kaulike;
• Kākoʻo ke kikowaena V.35 i ka plug-hot;
• Hāʻawi i nā ʻano uaki 3: Uaki kūloko, uaki waho, uaki laina E1;
• AC 220V, DC-48V, DC+24V, DC Mana a me ka Polarity-Free.
