Telecommunication Standard The European Telecommunications Standards Institute (ETSI) has identified a change in the requirement of the power spectral density (PSD) for Basic Rate Interface ISDN.

Section A.12.4, Power Spectral Density, of ETSI TS080 states the following: s The upper boundary of the power spectral
