Low and high frequency electromagnetic compatibility (EMC) mitigation techniques for telecommunication installations and systems – Basic EMC Recommendation |
Recommendation ITU-T K.37 defines mitigation techniques which the telecommunication operators may use to avoid disturbances, interference and damages caused by power and electrified railway plants, radio transmitters, both intentional and unintentional, and electrostatic discharges.
This Recommendation contains guidance for the telecommunication system normal operation:
–use of telecommunication equipment fulfilling relevant electromagnetic compatibility (EMC) requirements;
–proper installation practices such as well-controlled earthing and bonding networks and a.c. power distribution networks in buildings, avoidance of disturbing equipment close to telecommunication equipment, environmental control and welldesigned cabling;
–proper working practices such as avoiding use of hand-held radios close to telecommunication equipment and applying special precautions when handling electrostatic discharge sensitive devices;
–proper working practices in areas subject to high levels of low-frequency induction.
Special mitigation methods like shielding and filtering are discussed for cases where EMC problems arise.
This Recommendation does not include circuit or equipment design rules or guidelines for manufacturing – it is noted that this information is already widely available.
