Last version of EN 301 489-1 version 5 is know in line with CISPR/EN500024.
The test level for telecommunications ports, intended to be directly connected to the telecommunications network via outdoor cables, shall be 1 kV line to ground as given in EN 61000-4-5 [11], however, in telecommunications centres 0,5 kV line to ground shall be used. In this case the total output impedance of the surge generator shall be in accordance with the basic standard EN 61000-4-5 [11]. The test generator shall provide the 1,2/50 µs pulse as defined in EN 61000-4-5 [11]. This version was just published by ETSI the 16 of November 2004.
