1RU QAM Analyzer me te Kapua, te Taumata Mana me te MER mō te DVB-C me te DOCSIS, MKQ124

Whakaahuatanga Poto:

He taputapu tātaritanga QAM kaha, ngāwari hoki te whakamahi a MKQ124, 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 ka nui ake ngā uara o ngā tawhā kua tohua 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.

He taputapu tātaritanga QAM kaha, ngāwari hoki te whakamahi a MKQ124, 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, me te tuku mahanga SNMP i te wā tūturu mēnā ka nui ake ngā uara o ngā tawhā kua tohua i ngā paepae kua tautuhia. Hei rapurongoā, ka taea e te WEB GUI 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.

He taputapu tātaritanga QAM kaha, ngāwari hoki te whakamahi a MKQ124, ā, i hangaia hei aroturuki me te ripoata i te hauora o te whatunga Taura Mamati me te whatunga HFC.

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 nekenga o ngā kaiohauru, ko MKQ124 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 MKQ124 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.
