ITU-T Recommendations

Recommendation ITU-T K.102 defines the basic electrical parameters to be met by fixed-voltage thyristor overvoltage protector components used for the protection of telecommunications equipment or lines from surges. Examples of equipment include those located either within a telecommunications centre [b-ITU-T K.20], customer premises [b-ITU-T K.21], in access or in trunk networks [b-ITU-T K.45]. It is intended that this Recommendation be used for the harmonization of existing or future specifications issued by thyristor surge protective component manufacturers, telecommunication equipment manufacturers, administrations or network operators.
