The process of migration
to BT’s next generation
network
Presentation for corporate businesses
issue 2 8 July 2009
Information correct at time of publication.
Introduction
The purpose of this presentation is to:
Provide an overview
of the process of
migrating to BT’s
next generation
network known as
21CN.
Highlight how the
impact of the
migration can affect
your business and
outline mitigating
plans in place.
Provide details on
useful sources of
additional
information.
The overall aim is to build awareness of the process of migration to 21CN.
2
What is 21CN?
o
BT is upgrading its voice, broadband, and ISDN lines to a next generation
network (NGN), known as 21CN.
o
An NGN is an intelligent, future-proof network capable of delivering
communications services that will meet customer requirements in the coming
decades. It offers users access to different service providers and supports
generalised mobility, allowing for consistent, all-over service provision to users.
o
Switched-on is the name of the programme of public information to
communicate about the process of migration to BT’s next generation network.
o
This communication is being managed by a working group of
representatives from service providers, resellers, industry associations and
Ofcom.
3
Why is BT building a new network?
o
Corporate and public sector customers – and their customers
too – are demanding more advanced communications
services. They want greater choice, greater control, richer
services and the opportunity to be more productive and to
expand their customer base.
o
As a result, the communications industry needs a softwaredriven customer network to enable the delivery of a new,
simpler portfolio of next generation services that will meet
customer requirements in the coming decades.
o
In 2008 BT began to introduce a range of next generation
services to the industry including broadband and Ethernet.
o
Existing services will see minimal changes in functionality,
although new features may be available as a result of being
switched-on. 21CN will enable enterprises to rapidly
customise software applications to meet their specific
business needs.
4
Who will be affected by this migration?
o
BT delivers network services to over 700 telecoms
suppliers that provide services to customers across the
UK. So even though you may not be a direct
customer of BT, your services may still be carried over
the BT network, and therefore you may be affected
by these changes.
o
All customers whose products and services run over
the BT network will be affected by a short interruption
on the night of migration at a point in the next few
years. There will also be other short breaks as we
prepare for switched on, similar to current essential
maintenance interruptions to service on the existing
network. Where these service interruptions are
material BT has provided a planning window to ensure
disruption is minimised.
Cable networks, plus customers of Kingston Communications in East Yorkshire will not be affected. Mobile networks are not affected by the migration to 21CN.

Represents current thinking
By collapsing 17 of BT’s existing networks into one global platform and reusing
capabilities and removing complexity, 21CN will deliver services to customers
more quickly and more securely.

Voice migrations – progress to date
o
Working in collaboration with the Industry, BT has
implemented initial voice line migrations in the South
Wales area to test all processes before rolling out to other
areas of the UK.
o
Aprox 75,000 voice lines across 15 sites, covering two
Digital Local Exchanges (DLEs) in the South Wales area
have been successfully migrated to 21CN.
o
The network has been stable and call quality as good as,
or better than, the current network.
o
During 2010 a further 275,000 customers will be migrated
to test on an industrial scale and prepare for voice
migration activities outside the South Wales area.
o
Dates for future voice line migrations, outside the South
Wales area, will be shared with the communications
industry when available. Your service provider will be in
touch with you when migration activities are happening
in your area.
Broadband and ISDN migrations
Broadband
o
Broadband migrations to 21CN are dependant on the broadband service
provider in terms of if and when they offer next generation broadband services
in an area once the local exchange has been enabled.
ISDN
o
Pilot migration activity to date has not included ISDN lines. We are currently
waiting for dates when BT will carry out a similar pilot in Northern Ireland to test
ISDN migrations prior to rollout.
Reliability, continuity and resilience
A well
designed,
highly resilient
network.
A secure, safe

Building a robust network
o
BT is working closely with service providers,
manufacturers and industry bodies to test systems,
services and customer equipment to ensure full
interoperability with BT’s next generation network.
o
World class testing facilities at Adastral Park and
Swansea undertake an extensive range of system and
process testing and technology ‘proving’ activities.
o
BT completes its operational readiness and service
introduction proving with activities in the wider
network prior to full service launch.
o
This is performed in conjunction with other service
providers to ensure full interoperability.
11
Customer Premise Equipment (CPE)
compatibility testing
o
Testing to date shows that the vast majority of
customer equipment connected to current
telephone lines and broadband services will work
normally on the network once it has been switchedon.
o
A comprehensive and rigorous testing programme is
ongoing.
o
The approach taken is to test a representative
sample of each type of equipment.
o
Where any issues are noted, more exhaustive testing
within a category is undertaken.

12
Will my products be affected?
o
Some products will remain on the current network and will
be withdrawn over time – examples are Private Access
Broadband, IPstream and DataStream circuits.
o
If your employees have broadband services that are used
for home working their service could be affected by a short
interruption when they are upgraded should their service
provider choose to introduce next generation broadband
products. Please note that whilst the Broadband service is
being migrated there will be a voice service outage.
o
BT has already withdrawn some products such as ISDN 2DASS
and ISDN 30 1.421 and provided replacement options. More
products may be withdrawn as part of portfolio
management. More information can be found on the
switched-on website or by talking to your service provider.

Note: The BT product retirements programme is complementary but managed and run
independently of the 21CN implementation programme. Following input from Ofcom and the
industry, the presence of or reference to this retirements information with other 21CN materials is
provided for a customer’s convenience and does not imply interdependence between the two
programmes.
14
Emergency and Critical services
Special measures will be taken by service providers who
provide blue light services to minimise the impact on
providers of emergency and critical services at the final
point of migration (from 2010 onwards):
oMigration will not be attempted if emergency/essential calls are in
progress*.
o21CN migration plans already take into account existing resilience
arrangements to protect these services.
oDetailed local operational plans will be developed.
oMigrations impacting on 999 primary, secondary and alternative routings
will not coincide.
oPriority will be given to migrating blue light control centres on
Tuesday/Wednesday and Wednesday/Thursday nights where possible.
To aid planning, emergency services will be told:
oThe week of their migration nine months before.
oThe night of their transfer three months before.
* Unfortunately emergency services cannot be detected on a VoIP phone.
15
How will my business be affected by
the voice/ISDN migration activities?
From 2010 onwards:*
o
Your voice/ISDN services will experience a small
number of very short interruptions due to premigration activities. These will prepare your lines for
migration to 21CN.
o
Customers may experience some minor service
interruptions at the final point of migration to 21CN.
o
This only applies to a range of services that are
provided over the BT network.
o
If you have multiple sites in different locations these
sites will probably not be migrated at the same
time.
o
Your service provider will contact you to discuss
when the migrations will occur.
* National migrations to areas outside of South Wales will not commence until some time after July
2010. You will not be affected until then unless you have a business based in the South Wales area.
16
How will my business be affected by
the voice/ISDN migration activities?
From 2010 onwards:
o
All voice/ISDN migration activities will take place out
of hours (00:01 – 06:00 unless otherwise stated) from
Monday to Thursday.
o
On the night of migration voice services will have an
interruption of up to 3 minutes for outgoing calls and
up to 10 minutes for incoming calls.
o
BT will take all reasonable steps to protect any calls
that are in progress on the night of migration.
o
From 10pm on the night of migration to 9am at the
latest the following morning, no further changes can
be made to your services. For example, diverts
cannot be amended. This is known as the network
services freeze.
17
What will I need to do?
o
Your service provider will keep in touch with you to
plan your migration activities and implement any
alternative routing plans if required for the final night of
migration.
o
Review the switched-on website to understand if any
incompatible CPE is being used on your network.
o
If any of your services are “blue light” services, please
contact your service provider to discuss how
migrations will impact you.
o
Build awareness of this forthcoming activity with
colleagues who need to know about this programme.
18
What is switched-on?
o
Switched-on is the name of the
programme of public information to
communicate BT’s migration to a NGN.
o
Switched-on is not commercial in any
way and is not designed to give any
single provider a competitive
advantage.
o
Switched-on will not communicate any
new services or benefits enabled by the
new network for BT or any other service
provider.
