In September 2005 Deutsche Telekom announced its plans to extend its fibre infrastructure
to the street cabinet in order to offer VDSL products. Deutsche Telekom has adopted a twostep
approach implementing fibre infrastructure in 10 big German cities 7 in a first step and
additional 40 cities in a second step. The investment for the VDSL infrastructure projects
amounts to € 3 bill (with € 500 million of these for the first stage of the project).
VDSL offerings require a hybrid infrastructure existing of copper and fibre with copper being
used from the subscriber distribution interface to the street cabinet and fibre from the street
cabinet to the main distribution frame. Thus, VDSL infrastructure constitutes a fibre to the
curb approach. Copper circuits in the distribution cable segment are dedicated whereas fibre
circuits in the feeder cable segment are shared between users. DTAG uses VDSL 2 as
transmission technology using the frequency spectrum up to 30.000 kHz.
By shortening the copper infrastructure (up to the street cabinet instead of the MDF) it becomes
possible to realize transmission speeds of up to 50 mbit/s upstream (5 mbit/s downstream)
with VDSL access (for distances of 1.000 m or less from the street cabinet to the
customer).
Deutsche Telekom has announced in its mid-year press conference 2006 to push the implementation
of its IP-based Next Generation Network. Investments shall be made earlier than
originally planned. It is intended to migrate the existing networks and all services provided
over these networks into a single IP platform.
By the end of 2006 DTAG’s VDSL network was deployed in 12 cities. It is envisaged to provide
27 cities with VDSL by the end of 2007 and the rest of the 50 cities from 2008 on a stepby-step
basis. Besides this VDSL roll-out Deutsche Telekom plans to offer ADSL2+ in 750
cities by the end of 2007 allowing speeds of up to 16 Mbit/s. Thereby it is intended to further
push IP-TV. Deutsche Telekom plans to have an IP-TV coverage of 17 million homes in
2007, either based on VDSL or ADSL2+ coverage. 8
Deutsche Telekom offers three product bundles based on ADSL2+ (“Entertain Basic”, “Entertain
Comfort”, “Entertain Comfort Plus”) and two product bundles based on VDSL2 (“Entertain
Comfort VDSL”, “Entertain Comfort Plus VDSL”). 9 All bundles require a telephone access
line (analogue or ISDN).
Netcologne
In July 2006 Netcologne 10 began constructing a fibre to the home network in Cologne. Based
on this network Netcologne offers Internet access with up to 100 Mbit/s. Offers are available
since December 2006. The first phase of the infrastructure roll-out covers an area in the city
of centre of Cologne. For 2007 network deployment is envisaged in further parts of the city
covering approximately 9.000 households. Within the next 5 years the whole city shall be
covered with a focus on multi dwelling units and industrial buildings. 11 Netcologne intends to
use existing in-house wiring. Netcologne offers bundles with access speeds of 10, 50 or
100 Mbit/s (with telephony either being part of the flat rate or charged on a per-minute basis).
