Access issues: Operational Support Systems and regulation

This article examines the regulatory issues surrounding Operational Support Systems (OSSs). Equal and non-discriminatory access to the incumbents’ OSSs, which perform a number of functions and are critical in market differentiation for operators, is a key element in enabling meaningful competition. This article assesses the regulation of access to OSSs in the US and the EU. It concludes that, as attention now turns to competition in access networks, resale and local loop unbundling, regulators have an important role to play in putting forward guidelines concerning minimum requirements for access to OSSs so as to enable real competition.
