Idivayisi isebenza ngamandla aphansi futhi ayikwazi ukuthola idatha ye-downlink evela esikhungweni sedatha.

I-DTU kumele ilayishe idatha ngenkuthalo futhi ifake imodi yokuxhumana ngaphambi kokuba isikhungo sikwazi ukuthumela idatha.

Ngemva kokungasebenzisi idatha, i-MDN311 ingena ngokuzenzakalelayo kumodi ye-PSM ukuze igcine ukusetshenziswa kwamandla okuphansi kulindile.

I-MDN311 isekela umsebenzi wokuhlela iskripthi. Abasebenzisi bangenza ngezifiso amafayela esikripthi ngesofthiwe yokucushwa kwezithombe zemishini, ukuze izinhlelo zokusebenza ezisendaweni zingadingi abalawuli abengeziwe, futhi kungadingeki bathembele epulatifomu yedatha ukukhipha imiyalelo yokuqoqa ukuze kufezwe ukuxhumana okuqondile nethuluzi. I-MDN311 Qoqa ngqo futhi ngenkuthalo idatha kusuka kuthuluzi bese uyibika epulatifomu.

Ukwenza Ngokwezifiso Ifomethi Yephakethe Ledatha Eguquguqukayo

Iphakethe lokubhalisa elenziwe ngokwezifiso:Abasebenzisi bangalungiselela ngokukhululekile okuqukethwe kwephakethe ledatha elithunyelwe lapho i-MDN311 ixhunywe okokuqala esikhungweni sedatha.

Iphakethe lokushaya kwenhliziyo ngokwezifiso:Abasebenzisi bangalungiselela ngokukhululekile okuqukethwe kwephakethe lokushaya kwenhliziyo elithunyelwe yi-MDN311 esikhungweni sedatha.

Iphakethe lekhanda elenziwe ngokwezifiso:Umsebenzisi angalungiselela okuqukethwe okuthile ngaphambi kwephakethe ledatha elithunyelwe yi-DTU esikhungweni sedatha ukuze ahlukanise uhlobo lwedatha noma isigaba.
