Audio wapamwamba kwambiri - Fiber-64Voice+4E1 Multiplexer JHA-PCO/S64E4F4C1 - JHA

Mwachidule:

Zida zotsatizanazi zimapangidwa ndi kampani yathu yapadera ya vlsi PDH optical fiber transmission pamaziko a chitukuko cha zida zowunikira zowunikira. Izi ndi 19 inchi 1 U rack unsembe, 64channel mawu, 4channel E1 mawonekedwe, ntchito ndi kusintha kwambiri. Khalani ndi alamu yabwino, makina amagwira ntchito mokhazikika komanso odalirika, kugwiritsa ntchito mphamvu zochepa, kuphatikiza kwakukulu, voliyumu yaying'ono.

Mawonekedwe:

• Zotengera eni Integrated dera;
• 1U19-inch rack-mount;
• 1-60 njira zofikira mawu, zimathandizira ID ya Oyimba ndi kubweza ntchito zolipiritsa polarity;
• ThandizoFoniNambala yogwirizana ya tsamba lililonse;
• FXO ndi FXS mawu madoko thandizo doko, FXO doko ndi docking PBX, FXS doko chikugwirizana ndi foni wosuta;
• Mawonekedwe a E1 amagwirizana ndi G.703 amalimbikitsa kugwiritsa ntchito kuchira kwa wotchi ya digito ndiukadaulo wokhoma wosalala;
• Itha kuzindikira pamene chizindikiro cha kuwala chatayika chifukwa cha chipangizo chotsitsidwa kapena chotchinga cha fiber, ndipo kudzera pa LED imasonyeza alamu;
• Ndi mapeto awa poona ntchito udindo anasonyeza ntchito kutali chipangizo;
• Perekani lamulo lakutali loopback mawonekedwe, zosavuta kukonza mzere;
• Kupatsirana kosabwereza mtunda wa 2 mpaka 120 km;
• Zosankha zingapo zamagetsi: AC220V, DC-48V / DC24V, ndi zina;
• DC-48V / DC24V magetsi ndi ntchito yodziwikiratu polarity, ikayikidwa popanda kusiyana pakati pa zabwino ndi zoipa;
• Telefoni mawonekedwe ndi chitetezo mphezi, mphezi anafika IEC61000-4-5 Short dera panopa yoweyula 8 / 20μs, lotseguka-nsonga linanena bungwe voteji 6KV mfundo.
