ITU-T K.58 PDF

The purpose of this Recommendation is to provide guidance aimed at ensuring safe and problem-free operation in co-located information and communication technology (ICT) installations from the viewpoint of electromagnetic compatibility (EMC), resistibility and safety.

This Recommendation deals with the following environments where equipment owned by several operators can be installed:

– telecommunication centres;

– data centres;

– remote electronic sites;

– in some instances, the customer premises when the equipment owned by operators is installed in that environment.

Minimum requirements are given in this Recommendation in order to ensure safe and problem-free operation and to reduce EMC, resistibility and safety problems. The main aspects are: safety for humans and equipment; electromagnetic emission and immunity; resistibility against overvoltage and overcurrent; and earthing. The procedures and countermeasures that are used in case of problems are also described in this Recommendation.

Also, this Recommendation provides guidance on determining responsibility when an EMC problem occurs. If national regulations or agreements for co-location between operators exists, then this Recommendation supports the items that these documents do not cover.

Requirements that are not related to EMC, resistibility and safety are outside the scope of this Recommendation.
