MKQ128 ndi QAM Analyzer yamphamvu komanso yosavuta kugwiritsa ntchito yomwe cholinga chake ndi kuyang'anira ndikupereka lipoti la thanzi la Digital Cable ndi netiweki ya HFC.
Imatha kulemba nthawi zonse miyezo yonse mu mafayilo a malipoti ndikutumizaSNMPmisampha munthawi yeniyeni ngati mitengo ya magawo osankhidwa ikupitirira malire ofotokozedwa. Pothetsa mavuto aWEB GUIimalola mwayi wofikira kutali/kwanuko ku magawo onse owunikira pa gawo la RF lenileni ndi zigawo za DVB-C / DOCSIS.
Pamene chiwerengero cha olembetsa a Digital Cable TV ndi DOCSIS chikuchulukirachulukira padziko lonse lapansi ndipo Ubwino wa Utumiki wakhala chinthu chofunikira kwambiri pochepetsa kuchuluka kwa olembetsa, MKQ128 ndi chida chabwino kwambiri chowunikira bwino khalidwe loperekedwa maola 24 pa tsiku, masiku 7 pa sabata, masiku 7 pa sabata. Wogwiritsa ntchito chingwe akhoza kuchiyika pamalo olowera/kumalo olumikizirana, pamtunda womaliza, kapena pamalo olembetsera.
MKQ128 ndi njira yaying'ono yoyendetsera ma rackmount kuti iyang'anire nthawi zonse mayankho a pafupipafupi/amplitude/gulu la nyenyezi/BER pa njira zonse za QAM. Pogwiritsa ntchito magawo owunikira awa, wogwiritsa ntchito akhoza kukhala wodzipereka pokonza vuto la mtundu wa chingwe komanso kupeza malo omwe kuwonongeka kukukhudza ntchito.
Mapulogalamu
➢Kuyang'anira netiweki ya DVB-C ndi DOCSIS Digital Cable (24/7)
➢Kuwunika njira zambiri
➢Kusanthula kwa QAM kwa nthawi yeniyeni
Ubwino
➢Kuyang'anira thanzi la netiweki yanu ya CATV patali komanso m'deralo
➢Kuwunika QAM nthawi yeniyeni komanso mosalekeza
