Summary:
|
Recommendation ITU-T K.45 specifies resistibility requirements and test procedures for telecommunication equipment installed between telecommunication centres and between a telecommunication centre and customer's premises building.
Overvoltages or overcurrents covered by this Recommendation include surges due to lightning on or near the line plant, short-term induction from adjacent a.c. power lines or railway systems, earth potential rise due to power faults, direct contact between telecommunication lines and power lines and electrostatic discharges.
Major changes compared with the 2008 version of this Recommendation include:
o updating the references;
o information on when to add protection to untested ports;
o adding test requirements for external coaxial cable ports;
