Two ADSL variants of the SpeedTouch™ exist:
The ADSL/POTS variant connecting to an analog Plain Old Telephone Service
(POTS) line.
The ADSL/ISDN variant connecting to a digital Integrated Services Digital
Network (ISDN) line.
You can easily identify your variant by checking the identification label located on
the bottom of your SpeedTouch™.
Use only the SpeedTouch™ variant which is appropriate for the DSL service
provided to your premises. Check with your Service Provider to determine whether
your SpeedTouch™ is adapted to ADSL service requirements.
The appropriate DSL service must be available at your premises:
ADSL service must be enabled on your telephone line.
As both telephone and ADSL service are simultaneously available from the
same copper pair, you will need a central splitter or distributed filters for
decoupling ADSL and telephone signals.
Always contact your Service Provider when installing splitters/filters!
Public telephone lines carry voltages that can cause electric shock. Only install
splitter/filters yourself if these are qualified for that purpose.
The SpeedTouch™ supports the latest ADSL standards:

RE-ADSL
ADSL2+
ADSL2 (ITU G.992.3 and G.992.4), being the successor of the well-known ADSL
standard, adds new features and functionality targeted at improving performance
and interoperability, and adds support for new applications, services and
deployment scenarios. Among the changes are
Improvements in data rate and reach performance.
Rate adaption.
Diagnostics.
Stand-by mode.
G.992.L Reach Extended ADSL (RE-ADSL) is an extension to G.992.3 ADSL2 that
allows to significantly extend the reach of throughput capabilities.
ADSL2+ (ITU G.992.5) is an extension to the ADSL2 standard that goes even further
in offering optimal broadbanding; it nearly doubles the maximum ADSL
downstream data rates to up to 20Mb/s.
