- It was agreed to revise Recommendation ITU-T K.5 (Joint use of poles for electricity distribution and for telecommunications) and to include it in the work programme of Q3/5.
Working Party 2/5 – Electromagnetic fields: emissions, immunity and human exposure
Working Party 2 made significant progress on its Work Programme and achieved the following key outcomes:
Question 6/5 - EMC issues arising from the convergence of IT and communication equipment
- Eight incoming Liaison Statements were received and examined during this meeting. Seven incoming liaison statements are related to Recommendation ITU-T K.60 “Emission levels and test methods for wireline telecommunication networks to minimize electromagnetic disturbance of radio services”.
