  1. CONSULT 21Broadband and LLU Working GroupBROADBAND AND LLU PRODUCTS - MIGRATION TO 21CNYnyr Roberts BTW16th June 2005

  2. 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."

  3. 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

  4. 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

  5. Sectors Consumer ISPs Business ISPs Aggregators Consumer ISPs require: Ability to create consumer propositions with control over bandwidth offered and contention or throughput. 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 CUSTOMER REQUIREMENTS FOR “DATASTREAM REPLACEMENT” ON 21CN

  6. DATASTREAM UPDATE • 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.

  7. DATASTREAM - WITHDRAWAL

  8. DATASTREAM - WITHDRAWAL Note that the Plan for the new replacement product will be shown separately when further details are available

  9. 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

  10. LLU ON 21CN – NO CHANGE

  11. IPSTREAM ON 21CN – NO CHANGE

  12. IPSTREAM ON 21CN

  13. NEW BROADBAND PRODUCTS ON 21CN Update of proposals shared with ISP forum on 14th June Any new Broadband products would sit alongside the existing IPstream and Datastream products if launched.

  14. ‘Access Link Package (ISH + CAL+ ATF)’ New Broadband Core Apps & Services Access Backhaul ‘IP Conveyance Pack 1’ SP Network Ethernet ‘IP Conveyance Pack 2’ Internet / WWW ‘IP Conveyance Pack 3’ OnNet Content/Apps Derived Voice Hosting / SANS Security etc LLU 3rd Party 3rd Party (IP, Ethernet) LLU Backhaul Tailored Configs & Flexible Backhaul Options Traffic Management And QoS New Core portfolio of Conveyance Options to on- or off- net destinations Broadband connectivity for SPs Wholesale and/or white label Applications and services Including hosting Multi-Service Ubiquitous Access POTENTIAL NEW BROADBAND PRODUCT STRUCTUREto be updated to show MSAN i/x following feedback in WG

  15. New Broadband Access New Broadband Access New Broadband Backhaul New Broadband Backhaul IP Data Delivery from SP (IPStream type) Non IP Data Delivery from SP (“DataStream” type) Conveyance Pack 1 Access Link Package (CP1) (ALP) IP Data Delivery from WWW (IPStream Central +) Conveyance Pack 2 (CP2) IP Data Delivery from Content/Applications Store Conveyance Pack 3 (CP3) POTENTIAL NEW BROADBAND PRODUCT STRUCTURE subject to update following feedback in WG Service Provider End User

  16. PLANNED NEW BROADBAND + CONVEYANCE PACKS • New Broadband • shared DSL access at exchange based MSANs. • ethernet aggregation (New Broadband Access). • shared backhaul to Metro Node sites (New Broadband Backhaul). • Conveyance Pack 1 + New Broadband Access/Backhaul • deliver IP traffic from service providers. • equivalent to the current RAS + IPStream Centrals. • Conveyance Pack 2+ New Broadband Access/Backhaul • deliver IP traffic from the WWW. • equivalent to the current RAS + IPStream Central Plus. • Conveyance Pack 3 + New Broadband Access/Backhaul • to connect to Content/Applications servers to deliver QoS enabled content e.g. Video. • Access Link Package: (ALP) + New Broadband Access/Backhaul • to deliver ethernet traffic from Service Providers to add own IP layer • for those requiring In Span Handover (ISH), Customer Access Link (CAL) or Across The Floor (ATF) connection.

  17. New Broadband ALP Planned Characteristics CP1 Planned Characteristics CP2 Planned Characteristics CP3 Planned Characteristics New Broadband Access Potential Characteristics New Broadband Backhaul Planned Characteristics • e.g. • Bandwidth; • QoS Characteristics; • Multicast; • Authentication • e.g. • CAL/ISH/AST; • Bandwidth; • Interface type; • QoS Characteristics; • e.g. • Bandwidth; • QoS Characteristics; • IP Address management; • e.g. • Symmetric/Asymetric split; • Wires only/Managed NTE split; e.g. - Bandwidth per exchange; - Minimum assured bandwidth; - Best Efforts bandwidth; • e.g. • CAL/ISH/AST; • Bandwidth; • Interface type; POTENTIAL NEW PRODUCT ORDERING STRUCTUREsubject to update following feedback in WG New Broadband Build Order Form

  18. 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
