Connection box for DSL installation

[memory31]

Dear Friends,

I got a phone call yesterday from Vodafone(Telekom?) regarding the comming appointment next week for DSL installation.

I was asked to locate the connection box and make sure it will be accessible for the technician. Unfortunately, I really don't have much idea how the "connection box" looks like, I searched around, and found the following..

Please help to suggest whether the required "connection box" for DSL installation is one of them, thanks..

All the best,

Meng
