This decision defines a national leased lines market based on SDH and WDM technologies, regardless of the speed. It concludes that Belgacom (now: Proximus) has significant power in this market and, as a consequence, imposes a series of remedies on the operator.

On 15 October 2009, following an appeal lodged by Belgacom, the Brussels Court of Appeal annulled this decision. The appeal in cassation lodged by BIPT against this annulment was rejected by the Court on 4 March 2013.

On 14 October 2010, BIPT adopted a renewal decision rectifying the annulled decision.
