Umgangatho ophezulu weRs485 Data Converter yeVidiyo – iFiber-64Voice+4E1 Multiplexer JHA-PCO/S64E4F4C1 – JHA

Isishwankathelo:

Olu chungechunge lwezixhobo luphuhliswa yinkampani yethu ekhethekileyo ye-vlsi PDH i-fiber optical transmission ngesiseko sophuhliso lwezixhobo zokuhambisa i-point-to-point optical transmission. Le mveliso iyi-intshi eyi-19 yofakelo lwe-rack ye-U, ilizwi le-64channel, ujongano lwe-4channel E1, Isicelo sibhetyebhetye kakhulu. Unomsebenzi ogqibeleleyo we-alamu, umatshini usebenza ngokuzinzile kwaye unokwethenjelwa, ukusetyenziswa kwamandla aphantsi, ukudibanisa okuphezulu, umthamo omncinci.

Iimbonakalo:

• Ngokusekwe kwisekethe edibeneyo yobunini;
• I-1U19-intshi ye-rack-mount;
• I-1-60 iziteshi zokufikelela kwilizwi, ixhasa i-Caller ID kunye ne-reverse polarity billing imisebenzi;
• Inkxaso yeNombolo yomnxeba umsebenzi ofanayo wesiza ngasinye;
• I-FXO kunye ne-FXS izibuko zelizwi zenkxaso, i-FXO port kunye ne-docking PBX, i-FXS port ixhunyiwe kwifowuni yomsebenzisi;
• I-E1 interface ihambelana ne-G.703 icebisa ukuba kusetyenziswe ukubuyisela iwotshi yedijithali kunye nobuchwepheshe obutshixekileyo besigaba;
• Iyakwazi ukubona xa isignali ye-optical ilahlekile kwisixhobo sokugqibela esinikwe amandla okanye isithintelo sefiber, kwaye nge-LED ibonisa i-alam;
• Ngesi siphelo kwimboniselo yesimo somsebenzi isixhobo esikude;
• Nika umyalelo ujongano lweloopback ekude, ukugcinwa lula komgca;
• Umgama wothumelo ongaphindwayo ukuya kuthi ga kwi-2 ukuya kwi-120 km;
• Iinketho ezininzi zemowudi yamandla: AC220V, DC-48V / DC24V, njl;
• Ubonelelo lwamandla lwe-DC-48V / DC24V olunomsebenzi wokubona ipolarity oluzenzekelayo, xa lufakwe ngaphandle kokwahlula phakathi kokulungileyo nokubi;
• Ujongano lwefowuni kunye nokhuseleko lombane, umbane ufikelele kwi-IEC61000-4-5 Isekethe emfutshane yangoku amaza 8 / 20μs, i-voltage evulekileyo yemveliso yemigangatho ye-6KV.
