ITU-T K.60 PDF

This Recommendation is intended to guide administrations when considering complaints of interference between telecommunication systems. It is not intended to set electromagnetic compatibility (EMC) compliance requirements. All involved parties (including but not limited to network operators, service providers or customers) are recommended to work together for resolving these cases.

The emission levels and test methods presented apply to:

– disturbing emissions from wireline telecommunication networks as defined in clause 3;

– only those frequencies that are launched onto the telecommunication wire-pair as part of the intentional transmission spectrum of the broadband system¹.

It covers, but is not restricted to, target levels regarding radiated disturbing emissions for such telecommunication networks as:

– networks using telecommunication cables and their in-house cabling extensions;

– networks using the low voltage (LV) alternating current (AC) mains network;

– community antenna TV (CATV) distribution networks.

This Recommendation provides an adequate level of protection of the radio spectrum, allowing radio services to operate as intended in the frequency range 9 kHz to 400 GHz. To date, it specifies target levels for radiated disturbance in the frequency range from 9 kHz to 6 GHz.

Application of defined test methods is restricted to the section of the telecommunication network in the vicinity of the radio interference; it is not necessary to apply the test method to all parts of the telecommunication network.

The emission target levels have been selected in order to ensure that disturbances emanating from telecommunication networks do not, in most cases, exceed a level which could prevent radio communication receivers operating in the near vicinity from functioning as intended.

¹ It is possible for other signals to couple into the telecommunication network and for these signals to propagate through the network and cause interference to radio reception. The procedure within this Recommendation addresses this possibility.
