Downgrading
Downgrading
OSI/MHS follows the CCITT Recommendation X.419, Appendix B, Section B.2.8 with
respect to downgrading of O/R attributes for relay to 1984 systems.
•
If the O/R address contains both a teletex string attribute and the corresponding
printable string attribute, the teletex string is discarded.
•
If the O/R address contains a teletex string attribute but the corresponding
printable string is absent, the address cannot be downgraded.
The Conversion Table
Note. The conversion from teletex to printable characters may cause the teletex string to be
truncated, because some teletex characters may expand to as many as two printable
characters. Characters beyond the end of the string are ignored.
