Information technology - Generic cabling for customer premises - Part 1: General requirements
ISO/IEC 11801-1:2017(E) This document specifies a multi-vendor cabling system which may be implemented with material from single or multiple sources. This part of ISO/IEC 11801 defines requirements that are common to the other parts of the ISO/IEC 11801 series. Cabling specified by this document supports a wide range of services including voice, data, and vido that may also incorporate the supply of power.
The contents of the corrigendum of April 2018 have been included in this copy.
