Future updates

Considering the implementation of the R&TTE directive (directive n° 1999/5/EC of the European Parliament and the Council of 09/03/1999), Proximus publishes the updates of its UNI (User to Network Interface) specifications 6 months before their official validation.

Nevertheless for minor updates or redesign, after BIPT (Belgian Institute of Postal services and Telecommunications) consent, this publication delay could be less than 6 months.
