www.DataSheet4U.com Advisory November 1998 T7234, T7237, and T7256 Compliance with the New ETSI PSD Requirement (Refer to the T7234, T7237, and T7256 ISDN transceiver data sheets.) 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 density of the transmitted signal shall be as shown in Figure 1, below. Measurements to verify compliance with this requirement are to use a noise power bandwidth of 1.0 kHz.
