NGN/NGA for Wholesale
July 7, 2015
Information to the wholesale market
FOR INFORMATION
Objective of the meeting
Belgacom is heading for a major transformation, impacting all
dimensions of our wholesale solutions.
It is of paramount importance to reach a common understanding
and a joint plan between Belgacom and all operators using our
infrastucture.
The MAIP program is not only an opportunity for Belgacom, but
also for you and all your customers.
The objective of the meeting is to explain our view of the
transformation, and give you a first set of information about the
program and its impact on your business.
As a next step discussions will be organised to further work out a
common plan.

The market evolves…
• Evolution of broadband demand & supply side:
• Demand for new and innovative services is increasing
• Evolution towards Triple play (voice, broadband, tv) or quadruple play
• Strong competitive pressure
from cable:
• High bandwidth, convergence, triple & quadruple play
• Cable competition claiming superior quality and speed compared to
Copper based technologies
• Without Belgacom’s investment in FTTC/VDSL, the threat for a “de
facto” cable BB monopoly could become a reality
• But the market still grows…

MAIP: Network Evolution
• Leverage the technological evolution
• Evolution of Fixed Voice network and Service Platform (VoIP, SDP)
• Migration of transport technologies (ATM/SDH, Ethernet, Mobile Backhaul)
• Anticipate the end of life of multiple legacy technologies in the transport
layer
• Invest in network simplification to reduce OPEX and increase operational
efficiency
First Phase:
Deployment of IP based Network
• Deployment of IP Based Access
Infrastructure (Fibre / VDSL2)
• Deployment of IP bases core
network (Ethane)
• Porting of the service portfolio on
the IP network
Unrestricted
Second Phase:
Consolidation / Outphasing
• IMS Introduction
• Outphasing of Access legacy
technologies (leased lines, X.25, PDH)
• Outphasing of Core legacy
technologies (ATM, SDH, PSTN) and
transition to IP based infrastructure

Target of the transformation
Broadband VDSL2 is the
network access choice
One single transport
network
Simplification in the network:
VDSL2 becomes the target fixed
platform in the access network:

A single converged backbone

Voice becomes VoIP
network that supports fixed and

PSTN, ISDN switches end of life
mobile voice, data and video

Massive customer migrations
ADSL, ADSL2+ insufficient to cope
with future bandwidth needs

networks

One single Service
Platform (IMS)

Used to provision multimedia
Replaces different physical
Migration to
multi-service
all-IP network

Easier and cheaper to run
OSS/BSS Transformation
New concepts allow us to become agile
and reduce time-to-market
services across any converged
network (fixed and mobile)

Replacement for TDM switches

Broadband Access
• Global technological evolution towards Ethernet
• Vendor support for ATM will vanish (maintenance issues)
• Saturations on ATM networks possible
 migrate the ATM backbone towards Ethernet
 avoid new investment
• By 2012: ATM to be phased out, Ethernet as uniform medium for access
technologies such as ADSL, ADSL2+, VDSL2

Broadband Access
Sub Loop Unbundling
• Unbundling at sub-loop (KVD) level is de facto already available in BRUO
since 2001, with the same access principles as in the LEX
• Belgacom has a mix of KVD topologies in the network, making a uniform
offer practically not feasible -> hence any SLU request will be accepted but
handled case by case to ensure the most efficient solution
• The ROP’s are not included in the SLU offer
• Not part of the traditional local access network.
• Invested under competitive circumstances
• No access obligation laid upon till present
Given the questions raised on economical viability1, it’s not Belgacom’s
intention to pro-actively expand today’s SLU offer, but rather work on project
basis when you have an effective demand for the concerned area(s)

Building Outphasing
• Currently 65 buildings are identified for closure
• Notifications have been sent for outphasing which will be scheduled
between 5 and 10 years from now. This is significantly longer than the
contractual terms of the reference offers.
• Impact on colocation and LLU services:
• In principle the MDF and feeding network are outphased completely
• In certain cases a limited MDF function might be kept, but only to serve a
limited number of distribution pairs (i.e. distibution directly connected to
LEX or KVD's - if any - that are out of the VDSL scope).
• In principle and in general the copper feeding network of the local net will
thus be outphased.
• In all cases the buildings will need to be freed completely.
Unrestricted
07 July 2015
Slide 43
Building Outphasing
• Belgacom will enter into discussions with you in the course of 2009:
• First impact and alternatives need to be studied
• Discussions in 2009 are largely in time to come to an agreement and
migrate before first effective closures
• Note that the current outphasing plan affects only a limited percentage of
your installed park (e.g. less than 9% of wholesale lines impacted)
• In general we foresee two years of preparation and 2 years of
implementation for closure of a building

We evolve…
• The MAIP roadmap is designed to match the evolving market needs and
technological evolutions
• Today’s ATM based broadband access will evolve to IP/Ethernet bitstream
access,
• a Wholesale and WBA VDSL2 service is available to choose your desired level of
investment
• ADSL over Ethernet will be developed in 2009 to enable smooth migration
• Given the questions raised on economical viability, it’s not Belgacom’s
intention to pro-actively expand today’s SLU offer, but rather work on project
basis when you have a reasonable business case for the concerned area(s)
• A list of 65 buildings has been published for closure, but with a notice period
sufficient to discuss and implement a smooth migration
• For today’s Leased Lines and related services, Belgacom Explore is designed to
provide a future proof solution
• A proposal for IP Voice Interconnect will be presented and discussed in 2009

Wholesale VDSL2
Splitter, NTP & internal cabling
• Stubs in customer premises internal cabling (i.e. star configuration or pairs
connected in parallel to connect the different rooms of a household) may cause
alteration of the VDSL2 signal, disturbing other VDSL2 lines
• One direct path without any stub between the introduction point and the VDSL2
NT (modem) => need a centralized splitter
• New NTP (TF2007) & its dedicated centralized splitter are suitable for both VDSL2
