Isishwankathelo

Esi sixhobo sibonelela nge-1-4 * E1 ujongano , I-Standard 2 yefowuni yomnxeba njenge-engineering order-wire (ukhetho). Ibhetyebhetye kakhulu. Inomsebenzi we-alam. Umsebenzi unokwethenjelwa, uzinzile, kunye nokusetyenziswa kwamandla aphantsi, ukudibanisa okuphezulu, ubungakanani obuncinci.

Ifoto yeMveliso

Iimbonakalo

• Ngokusekwe kwi-self-copyright IC
• Isixhobo sokubona imodyuli ebanzi eguqukayo
• Isebenzisa umnxeba oqhelekileyo we-2 wocingo (izibambo ezingezizo ezemfonomfono) ezisetwe njengefowuni yeodolo yobunjineli(uyazikhethela)
• Ujongano lwe-E1 luthobela i-G.703, lwamkele ukubuyiswa kwewotshi yedijithali kunye nobuchwepheshe besigaba sokutshixa
• Xa isignali yamehlo ilahlekile, inokubona isixhobo esikude sicinyiwe okanye ifayibha iqhawulwe, kwaye ibonisa i-alam nge-LED.
• Isixhobo sendawo sinokujonga imeko yokusebenza kwesixhobo esikude
• Nika umyalelo ujongano olude Loop Back, lula ukugcinwa kwelayini
• Umgama wothumelo ufikelela kwi-2-120Km ngaphandle kokuphazamiseka
• I-AC 220V, DC-48V, DC+24V inokuzikhethela
• I-DC-48V/DC+24V unikezelo lwamandla enomsebenzi wokubona polarity oluzenzekelayo, xa ifakwe ngaphandle kokwahlula phakathi kokulungileyo nokubi.
