6.1.3.1 General principles of interconnection and local loop unbundling in France<br />

Interconnection and local loop unbundling allow operators to access and use part of the incumbent operator’s<br />

network in return for payment to the incumbent operator of access and usage charges. Interconnection to the<br />

incumbent operator’s network allows the alternative operator to deliver its customers telephony traffic, while<br />

local loop unbundling offers it complete control over the line connecting the customer to the main distribution<br />

frame.<br />

6.1.3.1.1 Interconnection<br />

Interconnection means the linking together of several telecommunications networks in order to allow<br />

uninterrupted routing of communications between them.<br />
