The method includes performing a second classification event on first and second pairs, respectively, and detecting first and second predetermined class currents on first and second pairs, respectively. After expiration of a first variable delay period related to a first pseudo-random variable of the PSE, the method includes performing a third classification event on the first pair and detecting a first derived class current on the first pair. After expiration of a second variable delay period related to a second pseudo-random variable of the PD, the method includes performing the third classification event on the second pair and detecting a second derived class current on the second pair."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Detection, classification and mutual recognition of 4 pair power over ethernet","description":"A method for verifying interconnection of a PSE and PD with 4-pair PoE capabilities includes performing a first classification event on first and second pairs, respectively, and detecting a first pred","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9823720","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
