The EQM 008 is a compact edge QAM device that can provide 8 QAM channels for video distribution at the edge of a network. It accepts up to 8 MPEG transport streams over IP and outputs a modulated RF signal between 47MHz-1GHz to feed a local cable network. Key features include IP input via Gigabit Ethernet, support for 32-256 QAM modulation, and integrated web server for configuration and monitoring via SNMP. It is designed for small installations like communities or campuses requiring localized content distribution.
