Return Path Monitoring System

This rackmount headend system completes the requirement of DOCSIS 3.0 deployment where higher QAM on the return path becomes necessary and mandatory. The compact 1U rackmount chassis supports simultaneous and continuous ingress scanning of all 10 ports at a fast sweep rate of 200ms and dual ports are available for return path spectrum, QAM, MER, BER, and Constellation analysis. The unique system architecture is an affordable entry solution which can be scaled easily for future network expansions. The system is completed by a controller software package offering 3D graphics for detailed analysis of ingress, alarm detection/generation and trouble ticket management. A server option coupled to the system is capable of storing 30 days of ingress monitoring data for reference.
