Mea hoʻololi E1-V.35 UnframedJHA-CE1V1

Nānā nui

Hāʻawi kēia mea hoʻololi hoʻololi i hoʻokahi kikowaena E1 a me hoʻokahi kikowaena V.35 e hoʻokō ai i ke kikowaena E1 Unframed e hoʻololi ana i ka interface V.35. ʻO 2.048Mbps ka nui o ke kahawai ʻikepili. Loaʻa i ka polokalamu 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.

• Ma muli o ka IC pono'ī
• E1 Interface Hāʻawi i 2 impedances: 75 Ohm unbalance a me 120 Ohm kaulike;
• Ma hope o ka hoʻāʻo ʻana a me ka ʻōnaehana hōʻoia kūpono, e hoʻokō pono i ka protocol ITU-T V.35, G.703, G.704
• Loaʻa i ʻekolu ʻano Loop Back: E1 interface Loop Back (ANA)、V.35 Loop Back(DIG)、Kauoha i ka mamao
• V.35 Loop Back(REM)
• Loaʻa i ka pseudo random code test function, wehe maʻalahi ka laina, hiki ke hoʻohana ʻia ma ke ʻano he 2M BER Tester
• Kākoʻo ʻo V.35 interface i ka plug-hot, kākoʻo i ka pilina o DTE a i ʻole DCE
• 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
