This recommendation defines the list of checks to be performed during the functionality and interoperability testing of fixed Broadband access (further BBA) for PPPoE technology in an operator and Model networks. This document defines the tasks for BBA NUT testing and, a tests list for a model network, the reasonability of using one or other network for carrying out specified test groups.

This Report contains update to the work done at (CCIR, 1991). It shows the EVA communication requirements in the 410-420 MHz band and identifies typical communication characteristics for the fixed and mobile services in the band. The Report contains the interference investigation/analysis from the space research EVA systems to the fixed and mobile service systems in terms of power flux-densities incident at the surface of the Earth. A representative fixed service system and a representative mobile service system are used in evaluating interference to the space research EVA links. The power flux-density (pfd) levels in this Report under § 4 (called new proposed PFD limits) are those in No. 5.268 in the Radio Regulations (RR).

Radio noise from different sources introduce a certain unwanted background RF level at the input stage of any receiver that the wanted signals have to overcome for successful reception. Recommendation ITU-R P.372 defines the term radio noise as well as its different sources and states average values for each source separately. Below 1 GHz, noise from one or more of the following sources may be dominant, depending on the frequency: Galactic noise; Atmospheric noise due to lightning; Man-made noise (MMN).
