Introduction

• The purpose of this presentation is to

Provide an overview of the process of migrating
corporate businesses to BTs 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.

What is 21CN?

• BT is upgrading its voice, broadband, and ISDN
  lines to a next generation network (NGN), known
  as 21CN.
• 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.
• Switched-on is the name of the programme of
  public information to communicate about the
  process of migration to BTs next generation
  network.
• This communication is being managed by a working
  group of representatives from service providers,
  resellers, industry associations and Ofcom.

Why BT is building a new network?

• 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.
• As a result, the communications industry needs a
  software-driven customer network to enable the
  delivery of a new, simpler portfolio of next
  generation services that will meet customer
  requirements in the coming decades.
• In 2008 BT began to introduce a range of next
  generation services to the industry including
  broadband and Ethernet and in mid 2009 will
  introduce integrated voice and broadband.
• 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.

5
Who will be affected by this migration?

• 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.
• 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.

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 BTs existing networks into
  one global platform and reusing capabilities and
  removing complexity, 21CN will deliver services
  to customers more quickly and more securely.

The 21CN programme is now prioritising the
delivering of next generation services ahead of
replicating old services and introducing windows
for voluntary upgrades to new services before
planned migration.

Migration options

• Your service provider may determine that they
  want to offer a particular service during this
  period
• You will be advised by your service provider of
  any products that they will make available during
  this period
• Your service provider will make the choice to
  move all or part of its customer base on a
  geographic basis
• Your service provider will plan with you
  accordingly regarding geographical or product by
  product options

• BT specifies the timing (which may be subject to
  some form of consultation)
• Closure of switch or platform BT sets the
  date(s) and end users informed via switched-on
• Product retirements BT sets date of withdrawal
  from new supply as well as migration windows or
  off by dates and Service Providers can
  influence timing within those windows

Preparations underway

Building a robust network

• BT is working closely with service providers,
  manufacturers and industry bodies to test
  systems, services and customer equipment to
  ensure full interoperability with BTs next
  generation network.
• World class testing facilities at Adastral Park
  and Swansea undertake an extensive range of
  system and process testing and technology
  proving activities.
• BT completes its operational readiness and
  service introduction proving with activities in
  the wider network prior to full service launch.
• This is performed in conjunction with other
  service providers to ensure full interoperability.

12
Customer Premise Equipment (CPE) compatibility
testing

• Testing already completed identifies 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 switched-on.
• A comprehensive and rigorous testing programme is
  ongoing.
• The approach taken is to test a representative
  sample of each type of equipment.
• Where any issues are noted, more exhaustive
  testing within a category is undertaken.
• To view the latest list of tested equipment,
  visit
• www.switchedonuk.org/corporate/how/compatibility/

13
21CN - South Wales pilot

• Testing migration for PSTN voice replacement
• Customer Premise Equipment (CPE) testing
  continues
• A process will be available to allow alarm
  systems identified as falling outside published
  standards to be retained on the legacy network
• Platform testing
• End user communications testing

• Currently being scoped with industry
• Multi service pilot
• Migration to next generation voice, broadband and
  Ethernet
• Continued CPE testing

14
Will my products be affected?

• Some products will remain on the legacy 20C
  network and will be withdrawn over time
  examples are Private Access Broadband, IPstream
  and DataStream circuits.
• 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.
• BT are already withdrawing some products such as
  ISDN 2DASS and ISDN 30 1.421 and are offering
  replacement options. More information can be
  found on the switched-on website or by talking to
  your service provider.

Product portfolio impact

• MIGRATING Migration of existing products to
  21CN. Includes
• PSTN (includes, for example, CPS, Least-Cost
  Routing)
• ISDN2e, ISDN30e, WLR

• NEW New products enabled by 21CN. Includes
• Wholesale Broadband Connect
• Wholesale Broadband Managed Connect
• Wholesale Broadband Connect Converged
• Wholesale Ethernet

• RETAININGProducts retained on existing platform
  for the time being. Includes
• Analogue PCs, KiloStream, MegaStream, IPstream

• RETIRINGProducts that have reached the end of
  their life-cycle or that have a replacement in
  the new portfolio. Includes
• Pre-ETSI ISDN, Meter Pulse Facility, DataStream,
  Telex, Business Highway

• 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
  customers convenience and does not imply
  interdependence between the two programmes.

16
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)
• Migration will not be attempted if
  emergency/essential calls are in progress.
• 21CN migration plans already take into account
  existing resilience arrangements to protect these
  services.
• Detailed local operational plans will be
  developed.
• Migrations impacting on 999 primary, secondary
  and alternative routings will not coincide.
• Priority 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
• The week of their migration nine months before.
• The night of their transfer three months before.

17
How will my business be affected by the
migration?

• From 2010 onwards
• Your services will experience a small number of
  very short interruptions due to pre-migration
  activities. These will prepare your lines for
  migration to 21CN.
• Customers may experience some minor service
  interruptions at the final point of migration to
  21CN.
• This only applies to a range of services that are
  provided over the BT network.
• If you have multiple sites in different locations
  these sites may not be migrated at the same time.
  
• Your service provider will contact you to discuss
  when the migrations will occur.

18
How will my business be affected by the
migration?

• From 2010 onwards
• All migration activities will take place out of
  hours (0001 0600 unless otherwise agreed)
  from Monday to Thursday.
• On the night of migration voice services will
  have an interruption of up to 3 minutes for
  incoming calls and up to 30 minutes for outgoing
  calls.
• BT will take all reasonable steps to protect any
  calls that are in progress on the night of
  migration.
• 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.

19
What will I need to do?

• Keep in contact with your service provider(s) to
  plan for your migration activities and implement
  any alternative routing plans if required for the
  final night of migration.
• Review the switched-on website to understand if
  any incompatible CPE is being used on your
  network.
• If any of your services are blue light
  services, please contact your service provider to
  discuss how migrations will impact you.
• Build awareness of this forthcoming activity with
  colleagues who need to know about this programme.

20
What is switched-on?

• Switched-on is the name of the programme of
  public information to communicate BTs migration
  to a NGN.
• Switched-on is not commercial in any way and is
  not designed to give any single provider a
  competitive advantage.
• Switched-on will not communicate any new services
  or benefits enabled by the new network for BT or
  any other service provider.
