AND SERVICE PLATFORMS
In the case where France Telecom supplies partial unbundling, as
in France and Poland, voice communications (low frequencies)
are transferred on the Group’s network, while digital data (high
frequencies) pass via the third party operator’s DSLAM. The
DSLAM is thus the fi rst piece of equipment that is managed
separately by each access provider. It marks the boundary
between the shared copper wires and the network belonging to
each third-party operator.

Fixed broadband access on ADSL was available at the end of
2009 in France and Poland with a coverage rate approaching
100% on the incumbent local loop. It was also available in
different AMEA countries (Ivory Coast , Equatorial Guinea,
Mauritius, Jordan, Kenya, Senegal)
In the UK, Spain and Belgium, France Telecom provides fi xed
broadband access using these countries’ incumbent operator’s
local loop, either through unbundling or through bitstream offers.
FTTH very-high Speed Broadband Access
FTTx fi ber-optic access can extend the available ADSL service
offer to include upstream and downstream very high speed (up
to 100 Mbps in 2009), with improved response time.
There are different types of FTTx optical connection architectures:
FTTB (fi ber to the building), FTTH (fi ber to the home) and FTTC
(fi ber to the curb).
