Information technology - Generic cabling for customer premises - Part 9902: End-to-end link configurations

ISO/IEC TR 11801-9902:2017(E) This Technical Report provides definitions for, and examples of, cabling implementations described as end-to-end (E2E) links. The document also provides performance specifications to support Class D and Class E balanced cabling channels of ISO/IEC 11801-1. These specifications amend those channel specifications of ISO/IEC 11801-1 by including the impact of the free connectors in accordance with the interfaces specified in ISO/IEC 11801-3 used to terminate the E2E link. Test methods are provided in ISO/IEC 14763-4.
