This 8 in 1 IP Mux-Scrambling and modulation module is the Mux-scrambling-modulating all-in-one device. The modular design of this device makes each of its daughter cards stand-alone when operating. Each daughter card can receive the UDP format TS through GE port, it can also support up to 256 different IP address or port No.

It’s like the all-in-one device combined with 8 multiplexers(256 channels inputs), 8 scramblers and 8 QAM (DVB-C) modulators, which can output adjacent channel RF carrier(48M~860M)through the two RF output interfaces. 

Additionally, 1U chassis supports up to 3 modules (256 channels mux-scrambling-modulation) while the 4U chassis supports up to 12 modules (1024 channels mux-scrambling-modulation). 

This 8 IP Mux-Scrambling and modulation module has excellent integrated level, powerful performance and low cost, which is especially adequate for the new generation CATV system.
