There are a number of standards that test for CE on DC equipment. For telecom specifically, Bellcore in the US includes these tests in GR-1089-CORE (their general EMC document). In Europe, there are several ETSI standards which include DC emissions, but the general EMC document is ETS 300 386-1. This again is a general EMC standard and applies to non-radio equipment used in the public telecommunication network.
Current measurement is the primary technique for Bellcore. ETSI uses EN55022 voltage measurements as a base, but modify the frequency range, and specify a different 'LISN'.

You help is highly appreciated. Thank you all, Sincerely, Sarmad Albanna Hughes Network Systems --------- This message is coming from the emc-pstc discussion list.
