IP QAM and modulation module is the latest generational Mux-scrambling-modulating all-in-one device 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.
Dual power supply (option)
1 GE input, RJ45 interface or SFP
Supports up to 256 channels TS over UDP/RTP, MPTS or SPTS per card
Supports unicast and multicast, supports IGMP v2v3
Max 840Mbps for all input
Supports MPEG2/MPEG-4 re-multiplexing and MPTS/SPTS multiplexing
Supports accurate PCR adjusting
Supports PID filtering, remapping and PSI/SI editing
Supports up to 180 PIDS remapping per channel
Support DVB general scrambling system(ETR289), simulcrypt standards ETSI 101 197 and ETSI 103 197
Support multiplexed or scrambled TS over UDP/RTP output
8 adjacent QAM carriers output per card, compliant to DVB-C (EN 300 429) and ITU-T J.83 A/B/C
Supports symbol rate 5.0~9.0Msps, 1Ksps stepping
