ABSTRACT:
A UPBO is performed based on an attenuation of a first VDSL-cable connecting a first VDSL-CPE and a first VDSL-CO, and also based on an attenuation or electrical length of cable pieces between said first VDSL-CO and a further distant second VDSL-CO. Further, an extended DPBO for the first VDSL-CO is described not only regarding ADSL-cables originating from an ADSL-CO but also VDSL-cables from the further distant second VDSL-CO.
