I-MK440IE-P iyidivayisi ehlakaniphile ethuthukisa izici zayo eziyisisekelo zokudluliswa kwedatha ngokusekelwa kwe-IPv6, okuyenza ifaneleke ngokukhethekile ukudluliswa kwedatha ngokusekelwe kule nqubo.
Amaphuzu avelele
I-MK440IE-P iyimodemu yekhebula ethobelana ne-DOCSIS entsha®3.1 Ukucaciswa, futhi ihlinzeka nge-OFDM engu-2 kanye ne-32 ye-Single-Carrier QAM ezansi nomfula nge-front end ehlanganisiwe engu-1.2 GHz Full Band Capture (FBC), 2 OFDMA kanye namashaneli angu-8 eSingle-Carrier QAM akhuphukayo.I-MK440IE-P iyakwazi ukusekela ngaphezu kuka-5 Gbps ezansi nomfula nangaphezulu kuka-2 Gbps phezulu nomfula.
Isekelwe kumsebenzi we-Full Band Capture (FBC), akuyona nje iModemu Yekhebula, kodwa futhi ingasetshenziswa njenge-Spectrum Analyzer yesikhathi sangempela.I-Spectrum Analyzer inezici eziningi ezizuzisa ama-opharetha, njengalezi: ukunakekelwa kwezitshalo okusebenzayo kanye nokuxilongwa nge-inthanethi;bona izinkinga ngaphambi kokuba amakhasimende azibone;ukutholwa kokungena okukude kwe-LTE/off-air nokwenza kwasendaweni.
Nikeza ngoxhumano lwe-4-Port Giga Ethernet nesikhalazo nge-Standard POE+ (IEEE 802.3at) ne-POE (IEEE 802.3 af), imbobo ngayinye ye-POE ingalungiselelwa ngokwehlukana.
I-MK440IE-P izinga lokushisa liqiniswe ukuze lihlanganiswe kweminye imikhiqizo edingekayo ukuze isebenze ngaphandle noma endaweni yokushisa eyedlulele.

Isibonisi se-LED
Kunama-LED angu-6 ukukhombisa isimo se-CM.Kukhona: Amandla, i-DS, i-US, i-inthanethi, i-RF Level kanye ne-LED yesimo.
I-“RF Level”, i-LED enemibala emibili (enezici ezibomvu neziluhlaza) ibonisa ileveli ye-RF engezansi komfula embobeni yokufaka engezansi komfula, uma kuqhathaniswa nemikhawulo ye-DOCSIS/Euro-DOCSIS yesiteshi esingezansi kanye “namandla aphelele” ngale ndlela elandelayo:
| Isimo se-LED | Izinga |
| Okubomvu | phezulu kakhulu (izinga lesiteshi se-DOCSIS noma amandla aphelele) |
| Okubomvu + Okuluhlaza | ukuphakama komngcele |
| Okuhlaza | OK |
| Okukhanyayo Okubomvu + Okuluhlaza | umngcele ophansi |
| Okubomvu okukhanyayo | iphansi kakhulu |
| Valiwe | asikho isiteshi "esisebenzayo" se-DOCSIS |
| Isimo se-LED | Izolebulwa ngokuthi “STA”.On Ibonisa ukuthi i-CM ixhunywe kudivayisi eyiqaphayo. Ukushaya kwenhliziyo okusheshayo ekuqaleni, i-LED ishintshashintsha phakathi kokuvula nokuvala njalo ngemizuzwana emi-2 ngenkathi ithola amadivayisi agadiwe, bese ihlala ikhanya kancane. I-Flickering Flickers njalo ngemizuzwana eyi-10 ukukhombisa ukuthi ukuxhumana nedivaysi egadiwe kuyasebenza. Ukucisha Kubonisa ukuthi ukuxhumana nedivayisi egadiwe kulahlekile. I-LED icwayiza okwesikhashana njalo ngemizuzwana emi-5 ukukhombisa ukuthi uhlelo lokusebenza lokuqapha lwangaphakathi luhlola isixhumanisi sokuxhumana ukuze lubone ukuthi idivayisi iku-inthanethi yini. |
Futhi kukhona ama-LED anemibala embaxambili emi-4 ukukhombisa isimo se-Ethernet Port.
