IPTV to RF edge QAM type high density card based modulator chassis. Card bays support up to three T108 modulator cards with two independent systems per card, each with 4x adjacent QAM-256 outputs and 5 UDP IP addresses and ports. Each IP input can support MPTS inputs up to 108 Mbps, with the total input per Gigabit Ethernet port having a maximum aggregate program stream input up to 870 Mbps. This capacity allows the 3024 chassis to modulate up to 96 HD programs per chassis, or up to 400 SD programs when properly configured on QAM-256. The front panel has keyed switches for both power supply units, as well as a toggle for the alarm system. When armed, the unit will emit an audible alarm tone when an alarm event such as a lost video input is detected. The mainboard in the chassis includes a high capacity TS multiplexer that is able to route programs from one input card to another. This allows any input on any card to be dynamically remapped in any arrangement to any output configuration. This provides full matrix routing of all programs for cherry picking custom lineups for the RF outputs. Thor H-IPRF systems are the highest density digital channel modulators available. This platform is ideal for corporate MATV and hospitality industries.
