No problem, No it syncs with your DSLAM, it’s not a call. I will post a detailed answer later.

You DSL modem snycs to DSLAM often located in Serving area interface using the local loop/telephone line. First a line from your DSl modem goes to splitter ( Kali dabbi), it splits/combine the signal for your DSL and voice. This DSLAM acts as a "switch". A second filter is installed in you exch which splits/combine the voice (it travels further your POTS/PSTN which handles your telephone calls) and data signal.

A further explanation can be given by firecruz
