Subject/title: Parameters of thyristor-based surge protective devices for the protection of telecommunication installations
Summary: Recommendation ITU-T K.28 defines the parameters, test circuits and performance values of thyristor-based surge protective devices (SPDs) used for the protection of telecommunication installations (for example, exchange equipment, access equipment, telecommunication lines and subscriber or customer equipment). This Recommendation should be used for the harmonization of existing or future specifications issued by thyristor-based SPD manufacturers, telecommunication equipment manufacturers, administrations or network operators.
