Description:
SFT328 IP Mux-Scrambling and modulation module is the latest generational Mux-scrambling-modulating all-in-one device developed by SOFTEL. Each SFT328 daughter  card combines 8 multiplexing modules, 8 scrambling modules and 8 QAM (DVB-C) modulating modules, which makes it posssible that every daughter card works stand-alone. It supports maximum 256 IP MPTS/SPTS (per daughter card) input through the GE port and 8 adjacent carriers(30M~860M)output through the two RF output interfaces.
This SFT328 IP Mux-Scrambling and modulation module has adopted slot structure to allow maximum 3 SFT328 cards to insert one device simultaneously. To draw a conclusion, its excellent integrated level, powerful performance and low cost make it adequate for the new generation CATV system.
