3 Utopia Description
The new ADSL2+ standards will accelerate broad-
band applications beyond e-mail, web browsing
and data streaming. Internet Service Providers are
exploring several ways to increase their revenues
by offering new services and applications, and en-
larging their customer base. This can be accom-
plished using the increased quantity of new

features and annexes included in ADSL2+ prod-
ucts.
– Triple-play product offerings.
– On a 24+Mbps copper line link, several high-
definition video channels can be broadcasted
with new options offered to manage different la-
tency paths.
Increased subscribers base through extended
reach capabilities.
Reduced field deployment issues due to en-
hanced diagnostics capabilities and improved in-
teroperability.
Increased upstream speeds at lower costs for tele-
working and business symmetrical transmission
segments. By implementing bonding, both up-
stream and downstream bit-rates can be doubled
or further multiplied for high-end business applica-
tions.
The chipset allows OEM/ODM designers to ad-
dress the new services and applications needed
for the residential and SOHO markets up to the
large business segment. The chipset consists of a
new generation analog front-end chip (ST20184)
and digital chip (ST20196) integrating the DMT
modem and dedicated controller. When used to-
gether with an external network processor, a flexi-
ble and scalable platform can be developed to
handle the rapidly increasing bit rate demands and
the continuous introduction of additional multime-
dia functionalities and sophisticated networking
protocols.State-of-the-art ADSL2+ performance is
