Overview
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.
