Outline
DX324T IP Mux and modulation module is the latest generation mux-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, and support up to 256 different input address (IP address and port number). It’s like the all-in-one device combined with 4 multiplexers, (256 channels inputs) and 4 DVB-T modulators, which can output 4 carriers (40M~960M) through the two RF output interfaces. Additionally, 1U chassis supports up to 3 modules (12 channels mux-modulation) while the 4U chassis supports up to 12 modules (48 channels mux-modulation). This DX324T IP Mux and modulating module has excellent integrated level, powerful performance and low cost, which is especially adequate for the new generation IP CATV system.
