Question 24/V - Earthing in telecommunication systems (Continuation of Question 24/V, 1985-1988; revised title and wording) The main purpose of this Question is to establish Recommendations on the earthing of electronic equipment inside telecommunication buildings and subscriber premises. The further items related on earthing have to be considered with lower priority: - effectiveness of earth electrodes treated with salts or colloids; - life of electrodes; - methods of calculation for long-rod electrodes; -joint use of earth electrodes (telecommunication and power installations); -development of practical methods of electrode installation; - experience obtained with concrete-covered electrodes; - earth electrodes for submarine cable telecommunication systems which use the ground as a conductor for remote feeding of line repeaters; -problems of compatibility originated by the presence of earthing connections within the near electromagnetic field created by radio station broadcasts. Note 1 - It is desirable to prepare Recommendations and keep updated the Handbook on "Earthing of telecommunication installations". Note 2 - As background, the following documents have to be taken into account: COM V-22, 23, 38, 47, 48, 49, 50, 73, 82, 83 (1985-1988)
