Dtr 45 LogoPathTrak PNM is designed to find upstream impairments in the HFC plant that should be fixed to pre-empt failure. These are impairments that DOCSIS pre-equalization is supposed to compensate for in order to maintain quality of experience (QoE). The system mines pre-equalization coefficient data from customer cable modems, analyzes it, and presents information that can be used to target proactive network maintenance.

The end result is a list of high value service targets that suggest the issues that if fixed, would affect the highest number of customers with the most severe upstream impairments.
