BROADBAND AND LLU PRODUCTS
- MIGRATION TO 21CN
Ynyr Roberts BTW
16th June 2005
LEGAL NOTICE
"This presentation covers BT's current plans and intentions in
relation to Broadband and LLU products migration to 21CN.
These may be subject to change because detailed
implementation depends on a number of factors such as
supplier capability, regulatory requirements and final network
design."
UPDATE
•Vendor selection for 21CN announced, but contracts yet to
be signed
•21CN network design yet to be finalised
•Whilst the above should not affect 21CN delivery dates, it
does affect the dates when firm commercial proposals will be
available for products delivered on 21CN
•Detailed consultation with Datastream customers is in
progress – results to date indicate that the current plan for
Datastream must be revised
DATASTREAM CONSULTATION
PRINCIPAL CUSTOMER FEEDBACK
Industry regards the role of ATM technology to be finite and not fit for
purpose moving forward, but that legacy investments need protecting
Preference for new upstream Ethernet based product with potential for
increased flexibility and reduced cost
Support for “bridged working” as well as PPPoE and PPPoA
Customers would choose to migrate from Datastream to a new product
on 21CN that offered a better fit with their requirements at a time that
suits their business needs
Recognition that certain Datastream features (e.g. CBR VPs) will not be
reproduced on a simple Ethernet product on 21CN
End user shifts must be at minimum cost and cause minimal outage
CUSTOMER REQUIREMENTS FOR
“DATASTREAM REPLACEMENT” ON 21CN
Sectors
Consumer ISPs require:
•Consumer ISPs
• Ability to create consumer propositions with control
over bandwidth offered and contention or throughput.
•Business ISPs
•Aggregators
• Ability to create both low bandwidth offers for simple
internet and high bandwidth offers for Triple Play
solutions inc VoD, Voice and Fast Internet plus possibly
broadcast TV
Business ISPs/Providers require:
•Low Contention, high throughput, guaranteed products
•End to end network control of dedicated network paths.
• SDSL and 2 Way QoS.
Aggregators require:
•End to end network control of dedicated network paths.
• Ability to create IPstream look-alike products but to be
able to differentiate.
•Lower infrastructure costs using Ethernet
DATASTREAM UPDATE
Previous Position
Expect to Migrate Unchanged
with Transfer Engineering
Revised Position
Withdraw Datastream and
replace with new Ethernet
product on 21CN
NOTE
Consultation process will be started on Datastream withdrawal and
migration considerations. Datastream will continue to be delivered on
legacy platform until product withdrawal process complete.

Position
Service Structure
Note
Withdraw and replace Start consultation process for
with new product on
withdrawal of Datastream, to be
21CN
replaced by a new Ethernet based
product on 21CN. This follows detailed
discussion with Industry. Datastream
will be delivered on legacy network
until withdrawal is complete.

Continued consultation will take place
with Datastream customers to seek
consensus on the proposal to withdraw
Datastream and launch a replacement
product on 21CN

21CN products

Note that the Plan for the new replacement product will be shown
separately when further details are available
NEW PRODUCT UPDATE
BTW will launch a new Broadband product on 21CN to
replace Datastream
Requirements for this new product are being captured in
bilateral industry meetings
Deadline of 4 weeks to close requirements capture
process. Industry is invited to lead this process
Details of launch plan and commercials for new product
will be discussed in Consult 21 WG and regular ISP Fora
Details of migration proposals will be discussed in Consult
21 Working Group as they are developed

Position
Service Performance Expect to remain
unchanged.
This can only be
confirmed when new
network platform is
used to carry the
service and end to end
tests have been
performed - expected
early 2006 subject to
successful ITT closure.
Mass migrations to
21CN
Note
Most IPstream services will be repurposed for delivery on a new
Ethernet platform.
BT’s customers should be unaware of
whether the service is delivered using
the new or the old network.
Some services will remain on the
legacy network such as low end
Centrals and some L2TP Centrals that
rely on ATM and SDH functionality.
These products will be withdrawn over
time, to be replaced by new offerings
on 21CN

MSAN INTERCONNECT
Industry have a requirement for converged PoHs at approximately
15% of MSAN sites. Converged PoHs should be capable of
conveying a future bitstream product. BT have indicated that its
current thinking is that this requirement could be met at Tier 1
MSANs
At the MSAN Interconnect Working Group, it was agreed that the
details of a future bitstream product requirement should be
addressed by the BB & LLU Working Group before passing that
requirement to the NGN Interconnect Working Group to address the
architectural and interconnect aspects.
Members from BB/LLU WG who are interested in MSAN Interconnect
for data and Broadband should join the debate at the NGN WG
