BT's 21CN programme is subject to consultation and further development. Dates and
other details should be treated as indicative only, and subject to change
Pathfinder – the next steps – Pathfinder Volume POTS
• Again voice migrations only
• Will complete the further 7 DLEs in South Wales
- Cardiff, G, L, E, F, Bridgend, Cardiff B, Pontypridd
• Will complete the migration of up to 350K lines
• Migrations will take place January 2010 through to July 2010
• Same technology & architecture as Pathfinder – Ericsson
based call server
• August - October 2009 - Call Server and MSAN upgrades in
Pathfinder area
• Will provide key learning following migration of a complete DLE
in a night
Upgrades planned in the South Wales area
• Upgrades are planned between August and October 2009 when
there will be short voice line outages for end users
• We have worked extensively with the vendors to minimise the
impact to customers for example upgrades will be performed in
the early hours of the morning to minimise the impact
• In summary, each customer will experience outages on three
different nights. On one night there will be two outages.
Two nights, where call server* upgrades will affect customers
One night, where the MSAN* upgrade will cause two impacts.
* See notes pages for definitions
Upgrade programme – main benefits
The programme of upgrades in the summer will provide a number of key
benefits:
Reduces customer down time for future upgrades.
Resolves a number of customer premise equipment incompatibility
issues.
Prepares the area for further volume voice line migrations.

Consultation overview
•
First phase of IPstream consultation operated during summer 2008 and was concluded
in February 2009
–
–
•
Second phase of IPstream consultation (EUA withdrawal) started in May 2009
–
–
–
•
Confirmed two stage withdrawal framework
• Stage 1 – Centrals
• Stage 2 – End User Access (EUA)
Identified dependencies for withdrawal of Centrals
Proposed withdrawal framework was shared with CPs as part of an Industry workshop held on
21st May
Formal consultation document (CONDOC) was published on 10th June
Bi-laterals have been held during June/July in conjunction with the formal CONDOC
Datastream consultation has been ongoing since January 2009 and is now drawing to
a conclusion
– Series of detailed workshops have supported the formal CONDOC
– Framework for product withdrawal and new supply options have now been determined
– Continued discussions and migration planning will be conducted bi-laterally with
Datastream customers

before starting their

Next steps – bi-lateral framework
Proposed framework for bi-laterals:
• CPs strategy/aspirations for their end users
– What is the proposition for each type/segment
– Explore mapping that may offer ‘like for like’ options or create upsell opportunities
• Adding value through additional features
• Retaining customer through contract extension
– Analysis of footprints available for WBC (incl. FTTC) and EFM
•
Commercial case and how can the move happen?
– Understand when the ‘tipping point’ might be reached
– Opportunities for rationalisation of networks/infrastructure
– Dual running to Treble running to Dual running
– Timing and process for migrations
•

WBC/WBMC FTTC trial
BT Group’s strategy
• BT plans the biggest ever UK investment in
fibre-based super-fast broadband
Subject to the right regulatory environment
• In July 2008, BT announced its plans to
rollout fibre-based, super-fast broadband to
end users
– Up to 10 million UK homes by December 2012
– Up to £1.5billion investment
– Mixed economy strategy
• At Q4 results (May 2009), BT announced the
acceleration of its plans
– FTTC in reach of more than one million homes
& businesses by Spring 2010
• BT will offer fibre access on an open,
wholesale basis
BTW WBC/WBMC FTTC proposition
 Fibre access overlay incorporated into WBC.
 a single interface via WBC/WBMC for all types of access
– Including FTTC up to 40Mb downstream and up to 2Mb upstream
(optional up to 5M).
 a network with predictable behaviour that will support
applications
– Video telephony
– Multiple lines into the home/business.
– High quality voice.
– High speed surfing.
– Video streaming.

WHAT IS WBC FIBRE TO THE CABINET
WBC FTTC is provided by a DSLAM located in the street rather than in the exchange.
The DSLAM is then connected to the exchange by a fibre. PSTN service continues to be offered over the copper pair.
This can offer much higher Broadband line rates to End Users using VDSL 2 technology.

Industry consultation evolution
Bill du Cann
BTW, Industry Consultation
Summary of the evolution:
•
•
•
The Industry Consultation team is widening its remit - the type of engagement
is evolving
We need to reflect those changes in the way we are structured
There will now be 3 distinct workstreams
– Consult21 – delivery of 21CN plan, 21CN obligatory product consultation
– Customer Experience - driving through CE improvements to ensure an
excellent customer experience for CPs
– (3rd work stream) – collaboration with industry on non-obligatory product
developments or new requirements
•
•
•
The team’s objectives of awareness, engagement and influence are relevant to
all 3 workstreams, still the voice of the customer within BT
Engagement in the 3rd workstream will be in a similar format – bi-laterals &
expert groups where appropriate
Provides a clear on the context of our discussions and consultations

facilitate 21CN migrations
and obligations
• Improve the effectiveness of
consultation & customer
influence on the 21CN plan
• Provide customer insight to
inform portfolio and product
roadmaps for obligatory
products
• Ensure BT Wholesale is truly
listening to customer
requirements relating to end to
end Customer Experience
• Help BT to achieve its goal of
being number 1 for customer
service
• Identify and gain commitment to
resolution of generic CE issues
and establish priority areas for
investment in CE improvements
Examples of Work areas•
• Pathfinder
• WLR migration
• PC strategy
• MSIL
• 20CN Broadband withdrawal
•
•
•
C2M
Roadmaps
Systems Interfaces & usability
Billing
• To improve customer
collaboration on nonobligatory products.
• To introduce new areas for
discussion outside of
delivering the 21CN
workplan.
• Provide customer insight to
inform portfolio and roadmaps
for non-obligatory products.
•
Converged Business
Services discussions
• BB evolution
– inc SFBB & voice over
broadband
What does / doesn’t change?
• Consult21 remit doesn’t change
• The Consult21 Steering Board remains unchanged for
Consult21 activities & will continue to function as an escalation
point for issues under this workstream
• The Portfolio working group is disbanded, expert groups that sat
under this working group remain (if relevant to this workstream)
• You will see some changes to documents & information – these
will be proposed at the July Steering Board and if agreed further
communications will follow
• Keep an eye out for further briefings on the evolution

Multi Service Interconnect Link (MSIL) - resilience
Ethernet MSIL provides the transparent Ethernet link between the Point of Handover
to/from the CP’s network and the Multi-Service Access Port (MSAP) on BT’s Ethernet
Edge Aggregation device (EEA).
As such it allows CPs to access BT's range of IP based services on the 21CN

MSIL resilience progress
•
MSIL product launched in basic form in 2008
•
Feedback from customer workshops (primarily at Broadband) identified the
need for a resilient variant
•
A formal consultation was run during Spring 2009 to confirm requirements
•
Key requirements noted are:
– Resilient Access to be available via separate EEAs at all core sites providing
broadband interconnection.
– At Non- Core sites, resilience to be provided to at least the level of separate MSIL
cards and IOM, if separate EEAs not available (due to limited capacity
requirements).
– A PEW is not undertaken at the same time for different EEAs at the same site.
– Resilience must be retained during the life of the MSILs.
•
Next steps
– Feasibility study has been initiated
– Design touch-point meetings with interested CPs to be run during 2009
– Looking for product delivery in early 2010
