scope:
This Recommendation describes overvoltages and overcurrents protection of information technology equipment with digital port including Ethernet port regarding the testing found in [ITU-T K.20], [ITU-T K.21], [ITU-T K.44], [ITU-T K.45] and [ITU-T K.117]. Topics covered are:
• overvoltage and overcurrent events coupling into the network system depending on
- implementation condition,
- system configuration,
- powering condition (data only or provision of network powering) and
- link insulation;
• lightning surge resistibility test circuit approaches;
• power fault resistibility test circuit approaches;
• resistibility test circuit applicability to [ITU-T K.20], [ITU-T K.21], [ITU-T K.44], [ITU-T K.45] and [ITU-T K.117].
