Access options for Vectoring

Requires L2 BSA at/close to street cabinet

Termination of already existing competitor street cabinets if carrier

refuses to upgrade to Vectoring (not before 2017)

Termination of newly established street cabinets with 12 months notice if:

75 % of buildings in street cabinet area are connected to parallelinfrastructure (cable/fiber operator)

Telekom has rolled out more street cabinets than competitors

Availabiltiy of L2-BSA at street cabinet at the same price as sub-loop

(= EUR 6.79)

Right of termination (only for Telekom) Prerequisite for preventing access to sup-loop

Pricing: No provisions (ex-post regulation) yet

Telekom is not able to terminate, but to prevent sub-loop

First operator rolling out vectoring is privileged and investments areprotected

Prerequisite: All companies must offer L2 BSA as substitute
