FMUSER DTV4443 32-Channel IP QAM RF Modulator ke sesebelisoa se kotsi haholo le se ka tšeptjoang bakeng sa litsamaiso tsa khaso tsa CATV.

E ts'ehetsa likenyelletso tse fihlang ho 1024 ka likoung tsa 3 GE, 'me e na le liteishene tse 32 tse qhekellang khafetsa tsa QAM tse nang le li-carriers tse seng haufi (50MHz ~ 960MHz) ka sebopeho sa tlhahiso ea RF. Moralo oa eona oa ho lefshoa ha o ntse o hola le tlhophiso e feto-fetohang e fana ka ho eketseha ha sekhahla le ho ikamahanya le maemo bakeng sa litsamaiso tse ncha tsa khaso tsa CATV.

Litokiso tse nepahetseng tsa PCR, ho sefa CA, ho etsa 'mapa hape oa PID, le ho hlophisoa ha PSI/SI kaofela li tšehelitsoe, ka ho etsa limmapa tse fihlang ho 256 tsa PIDS mocha ka mong. Modulator e hlahisa li-carriers tsa QAM tse 32 tse seng haufi tse lumellanang le DVB-C (EN 300 429) le ITU-T J.83 A/B, ka tšehetso ea RS (204,188) encoding. Tsamaiso e bonolo ka tsamaiso ea eona ea marang-rang e thehiloeng marang-rang.
