Thread-topic: Documents posted for review.

All, David and I recently received a reply from the K.147 folks stating that they have edited the documents attempting to address the 802.3 concerns. They are asking us to confirm the changes. I have posted these four documents at the top of the K series private area of the PDCC site. Descriptions are provided below. I intend to discuss these in the PDCC ad hoc meeting scheduled for 4 June.

Document number: SG5-C0158
Title: K.21_Revision-Editing on K.21 internal Ethernet port surge test
Abstract: This contribution edit K.21 based on the discussion in C0133 and C0154 in ITU-T SG5 June 2025 meeting.

Document number: SG5-C108-R1
Title: Discussion on K.21 internal ports surge test
Abstract: Considering the previous discussion on K.21 revision on the last SG5 Q2/5 session meeting, this contribution presents a rationale regarding the requirements specified in ITU-T K.21 (08/2022) to lightning surge test level, insulation resistance test and differential mode surge test for internal ports. Discussions on test levels and a Brazilian experience of conformity assessment of ICT equipment is also provided.
