(256 ip input with mux) ip to analog converter

256 IP in, 8 Mux, 8 carriers out each module 1U with 3 modules NMS management

Outline

 

DX328A 8 in 1 IP to ATSC modulator is the latest generation Mux-modulating all-in-one device. Its modular design with each daughter card containing 8 multiplexing modules and 8 ATSC-T modulating modules makes each daughter card able to work stand-alone and receive the UDP format TS through GE port. It can support up to 256 different input address (IP address and port number) and output adjacent channel carrier (40M~860M) through the two RF output interfaces. Additionally, 1U chassis supports up to 3 cards (24 channels mux-modulation) while the 4U chassis supports up to 12 modules (96 channels mux-modulation).

This DX328A 8 in 1 IP to ATSC modulator has adopted slot structure to allow maximum 3 DX328A 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.
