1. a) provides guidance on how to select and assess installed channels which conform to ISO/IEC 11801‑1, and clarify if they also support ISO/IEC/IEEE 8802‑3:2017/AMD3 for 25GBASE-T;
2. b) specifies the methods to assess whether installed channels constructed with Category 7A, 7, or 6A components meet the 25GBASE-T requirements;
3. c) provides guidance to identify which channels are likely to meet the 25GBASE-T requirements to avoid unnecessary testing;
4. d) provides mitigation techniques to improve the performance of installed channels to meet the 25GBASE-T requirements;
5. e) provides cabling recommendations for new installations.

NOTE 1 The channel transmission performance specified in this document is derived from the 25GBASE-T requirements in ISO/IEC/IEEE 8802‑3:2017/AMD3.

NOTE 2 This document does not re-specify component or channel definitions of ISO/IEC 11801‑1.
