Taipitopito Hua
He taputapu tātaritanga QAM kaha, ngāwari hoki te whakamahi a MKQ128, ā, i hangaia hei aroturuki me te ripoata i te hauora o te whatunga Taura Mamati me te whatunga HFC.
Ka taea e ia te takiuru tonu i ngā uara ine katoa ki roto i ngā kōnae pūrongo, ā, ka taea hoki te tukuSNMPngā mahanga i te wā tūturu mēnā kua tīpakohia ngā uara o ngā tawhā ki runga ake i ngā paepae kua tautuhia. Hei rapurongoā i teAtanga Tukutukuka taea te uru atu mamao/ā-rohe ki ngā tawhā katoa e aroturukitia ana i te paparanga RF ā-tinana me ngā paparanga DVB-C/DOCSIS.
I te mea kei te piki haere tonu te maha o ngā kaiohauru ki te Pouaka Whakaata Taura Mamati me te DOCSIS puta noa i te ao, ā, kua noho te Kounga Ratonga hei wāhanga nui hei whakaiti i te hekenga o ngā kaiohauru, ko MKQ128 te taputapu pai rawa atu hei whakatutuki i te aroturukitanga utu-pai 24/7 o te kounga e tukuna ana ki ngā wāhi katoa o te whatunga Taura Mamati. Ka taea e te kaiwhakahaere taura te whakatakoto i tēnei ki te pito matua/pokapū, i te maero whakamutunga, i te wāhi rānei o te kaiohauru.
He pūnaha iti a MKQ128 hei whatanga hei aroturuki tonu i te auau/te whānuitanga/te whetū/ngā urupare BER mō ngā hongere QAM katoa. Mā te whakamahi i ēnei tawhā aroturuki, ka taea e te kaiwhakahaere te whai wāhi ki te whakatika i te take kounga taura, me te kimi hoki i te wāhi e pāngia ana te ratonga e te hekenga o te kounga.
