Recommendation X.403 (11/88)

Approved in 1988-11-01

Status : Withdrawn

This Recommendation was withdrawn because conformance testing concepts and methods defined in it were related to the 1984 MHS Recommendations and were not aligned with either the first or second versions of conformance testing standards. ITU-T X.480 (1992) refers to the 1988 "Blue Book" MHS Recommendations and was better aligned with the testing standards
