hake routines during connection establishment ensure that the standards
ADSL, ADSL 2 and ADSL 2+ are intercompatible.
Parallel to data transfer, ADSL also provides full and unlimited support for the

This is facilitated by splitters which separate the voice frequencies from the
data frequencies.
Some models feature an integrated modem for ADSL/ADSL 2+. It can be
directly connected to the splitter with the supplied cable.
