This Recommendation provides updated information on error-performance objectives for real digital fixed wireless links used in 27 500 km hypothetical reference paths and connections. It is the only Recommendation defining error-performance objectives for all real digital fixed wireless links. Performance events and objectives for connections using equipment designed prior to approval of ITU-T Recommendation G.826 in December 2002 are given in ITU-T Recommendation G.821 and Recommendations ITU-R F.634, ITU-R F.696 and ITU-R F.697. Recommendations ITU-R F.1397 and ITU-R F.1491 are superseded by this Recommendation. Example of a connection, path, link and hop are given in Annex 1. Definitions of the error performance events, derived from ITU-T Recommendations G.826 and G.828, are given in Annex 2. Examples of calculations of the error performance parameters are given in Annex 3.
