I-Fiber-4Voice +4FE Multiplexer JHA-P04FE04

Uhlolojikelele

Le divayisi ihlinzeka ngocingo lwe-1-4Channel, 4Channel 10M/100M Ethernet interface (Wire Speed ​​100M)，4Channel Ethernet interface iwukushintsha isixhumi esibonakalayo. Wonke umshini usebenza ngokuthembekile nangokuzinza ngokusetshenziswa kwamandla okuphansi, ukuhlanganiswa okuphezulu, usayizi omncane nokufakwa kalula nokugcinwa.

Izici

• Ngokusekelwe ku-self-copyright IC;
• Isiphetho sasendaweni singabonisa isimo sokuxhunywa kwefayibha yedivayisi ekude;
• Imbobo yezwi isekela i-FXO kanye ne-FXS port,I-Support FXO/FXS, i-Magnet phone Interface, i-FXO port docking nge-switchboard elawulwa uhlelo, imbobo ye-FXS exhunywe ocingweni lomsebenzisi;
• 1 ~ 4channel Ukufinyelela kwezwi, isikhombimsebenzisi se-Voice FXO / FXS, ukusekelwa kwe-ID yomshayeli / umsebenzi wokukhokhisa we-polarity / wefeksi;;
• Sekela amasayithi ahlukahlukene umsebenzi wokwabiwa kwenombolo;
• Isixhumi esibonakalayo se-Ethernet singasekela i-AUTO-MDIX (umugqa oweqa futhi umugqa oqondile ozivumelanisa nezimo);
• I-adaptha yamandla ye-AC220/5-12V yangaphandle, ingaba yi-adaptha yamandla ye-DC-48V/5-12V yangaphandle;
• Isixhumi esibonakalayo socingo esinokuvikelwa kombani, umbani ufinyelele ku-IEC61000-4-5 Igagasi elifushane lesifunda samanje esingu-10 / 700μs, i-voltage ephezulu yokuphuma kwe-6KV amazinga avulekile.
