scope:
The present document specifies European requirements for ADSL.
The definition of new line codes and/or transmission systems is outside the scope of the present document.
The present document endorses ITU-T Recommendation G.992.1 [2], the contents of which apply with the modifications being covered herein. In particular the aspects covered by the present document are related to:
1) Methods to allow the simultaneous delivery of ADSL and ISDN-BA services [1] on the single pair. For example the techniques and redefinition of the ADSL signals/parameters as defined in ITU-T Recommendation G.992.1 [2] to allow ISDN-BA baseband signals to occupy frequencies below ADSL (from here onwards referred as out-of-band transport).
2) Performance Objectives and Test methods for ADSL over POTS/ISDN-BA.
3) TS 102 080 [1] backward compatibility.
4) Power feeding for the transported ISDN-BA.
5) Latency.
6) ISDN-BA splitter characteristics.
