Ngā āhuatanga

• I runga i te mana-whaiaro IC
• He matakite hihiko whanui modular
• Ka whakamahi waea waea 2 paerewa (kaore i te kakau waea) kua tautuhia hei raupapa waea-waea-waea (he whiriwhiri)
• E ū ana te atanga E1 ki te G.703, ka tango i te whakaora karaka mamati me te hangarau raka-waa maeneene
• Ka ngaro te tohu whatu, ka kitea kua mutu te hiko o te taputapu mamao, kua momotuhia ranei te muka, me te tohu whakaoho ma te LED.
• Ka taea e te taputapu rohe te tiro i te ahuatanga o te mahi a te taputapu mamao
• Homai whakahau te atanga mamao Loop Back, ngawari te tiaki raina
• Ko te tawhiti o te tuku ka eke ki te 2-120Km me te kore e aukati
• AC 220V, DC-48V, DC+24V ka taea te whiriwhiri
• DC-48V/DC+24V toha hiko me te mahi rapu polarity aunoa, ka whakauruhia kaore he wehewehenga i waenga i te pai me te kino.
