Telecommunications - User Premises Equipment - Surge Resistibility of Smart Grid Equipment Connected to either DC or 120/240 V Single Phase AC and Metallic Communication Lines
Applies to premises equipment that is connected to one or more metallic conductive communication line(s) and either a DC power source, or a 120/240 V single phase AC power service with the neutral grounded at the service entrance. This standard specifies the test procedures and resistibility requirements under which the communications ports of the equipment shall continue to demonstrate basic functionality when subjected to overvoltages and overcurrents on either the power lines or the communications line(s). Overvoltages or overcurrents covered by this Standard include surges due to lightning on or near the power lines or telecommunications line(s).
