ITU-T Recommendations

This Recommendation specifies the electromagnetic compatibility common requirements and the test methods for wire-line telecommunication network equipment, used in a public telecommunication networks to provide telecommunications services: voice, data, audio and video to the end-users, using all applicable media and all kinds of wire-line access technologies, such as DSL, POTS, Ethernet, E1, fibre or others.

Test conditions for all kinds of wire-line telecommunication network equipment are described, e.g. access equipment, router and switching equipment, optical transmission equipment, data centre and cloud computing equipment and power supply equipment (including HVDC).

This Recommendation describes the specific testing levels to be applied to wire-line telecommunication in different environments, such as telecommunication centres, customer premises and outside plants.
