PR-3232 IP MUX Scrambling QAM Modulator

QAM Modulator MODEL: PR-3232 Download

Product Outline

PR-3232 IP Mux-Scrambling QAM modulation module is the latest generation mux-scrambling-modulating all-in-one device. A single module supports maximum 512 IP (MPTS/SPTS) input and 24 carriers output as well as 24 IP output after multiplexing and scrambling process (RF output for local transmission and IP output for remote sub-head end). It adopts the slot structure with one device supporting maximum 3 PR-3232 modules and 72 channels mux-scrambling-modulation. Each module can work standalone. With its powerful performance and low cost, PR-3232 is especially adequate for the new generation CATV system.
