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
