Outline

The DX324 a 4 IP Mux-Scrambling and modulation module is the latest generational Mux-scrambling-modulating all-in-one device with high integrated level and performance. The modular design of this device makes each of its daughter cards stand-alone when operating. With each daughter card can receive the UDP format TS through GE port, it can also support up to 12 different IP address or port No. It’s like the all-in-one device is combined 4 multiplexers with 12 channels inputs, 4 scramblers and 4 QAM (DVB-C) modulators, which can output adjacent channel RF carrier(48M~860M)through the two RF output interfaces. Additionally, the 1U chassis for this modulator supports up to 3 modules (12 channels scrambling-modulation) while the 4U chassis supports up to 12 modules (48 channels scrambling-modulation). This DX324 4 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.
