ITU-T K.123 PDF

This Recommendation defines the emission requirements for electrical equipment that is installed inside or adjacent to telecommunication facilities.

This Recommendation applies to electrical equipment such as air conditioning systems, personal computers, displays, printers, maintenance robots, and security systems including surveillance cameras which are not the part of telecommunication network. Lighting equipment and power equipment are not covered by this Recommendation.

Telecommunication equipment that directly provides telecommunication services are excluded from the scope of this Recommendation as they are covered by specific electromagnetic compatibility (EMC) Recommendations.

This Recommendation specifies measurement methods and limits for conducted emissions in the frequencies from 9 kHz to 30 MHz and for radiated emissions from 30 MHz to 6 GHz.
