  1. Consult21PC/PPC WG update • John Lee, Energis • Industry Co-chair • 16 May 2005

  2. Private Circuit and PPCs • First meeting 19 Jan 2005 – 23 industry reps from 12 companies • Second meeting 23 Mar 2005 – 14 industry reps from 9 companies (including 1 MOLO for RBS) • Next meeting May 26th, just prior to regular PPC Industry Forum • Up to 17th Jan – BT21CN statement was PC/PPC to be emulated • 17th Jan – current PPC to stay, review sub-1M platform in 2008, keep SDH for others • Panic over. Perhaps.

  3. Scope • to understand and track the impact of 21CN on Private Circuits (PCs), Partial Private Circuits (PPCs) and Wholesale Extension Services (WES) • to ensure that existing product features are maintained where necessary • to ensure that we work together to endeavour to avoid stranded assets at handover points and interconnect sites • to work together to identify synergies with PPC handovers for physical layer interconnection to NGN

  4. Method of Closure • Clearance of issues raised and actions taken at PPCs Working Group meetings and Industry forums – Steering Board confirmation required for issues clearance • Clear ownership of issues and actions which progress into the 21CN and non-21CN product portfolio development stage

  5. Issues 1 • BES, BPC – under BB&LLU or PC&PPC WG? • Technicalities suggest one way, commercials say another • Co-chairs of each to attend the other WG • DPCN platform review in 2008, possibly closure in 2011 • Particular market segments concerned about alternative products with key characteristics that may differ – e.g. Utilities (National Grid, RECs etc) – do we need new PPC SoR? • Analogue over Digital, but what about baseband copper?

  6. Watching Brief 1 • No impact on non-DPCN PPCs – but…. • John Morden has specified separacy, diversity, high-availability etc in his system request – but awaits system design feedback • PDH kit at third-party site will become obsolete – but likely to be stop for new supply but fill up what is there • New SDH delivery methods will be added via PPC forum, both Third Party and Point Of Handovers • No 21CN node data finalised to show Metronodes and MSAN mapping, so OLOs cannot plan network expansion with certainty - “new NIPP” • New SDH core, so move from current Mesh/MSH will cause service outage on existing traffic – scale, timing unknown

  7. Issues 2 • Point of Handover – multi-service capability • Exists now on SDH pipes - TDM for vocie, ATM for Datastream, TDM for PPCs • NGN interconnect WG proposing Ethernet over SDH and Ethernet • WES Industry forum asked for aggregation of Ethernet as ATM, MPLS and/or SDH – response says any Ethernet on SDH must tie in with 21Cn architecture and new products • So now have current PPC and WES product lines tied to 21CN strategy • How to decouple and allow industry to develop with sensible building blocks ?

  8. Issues 3 • Stranded Assets, Node closures • Concern if Closure of BT SDH node sites but OLOs have interconnect • Offer last week – all current CSH and ISH nodes to continue. If closure needed, full debate with industry, then the SAN process. • Offers reuse of fibre to a BT site previously used for DLE, and feasibility on reuse of kit (though costs of new supply likely to be similar if not cheaper than refurbish) • Did not include Tier 1 pricing to continue for current price control period (2008) • No mention on impact if serving equipment moves to new site – BT to extend at their cost, but if removes separacy etc? • SoRs for bulk shift from PoH 1 to PoH 2?

  9. Watching brief 2 • BTGS and OLOs need low-speed PPCs independent of MSAN offerings • Nowadays have a PPC and ISDN backup, or PPC plus PPC – so if low speed moves to SDSL and ISDN is on MSAN – then what? • Distance limit of copper and cost-hike to fibre • 1M PC/PPC – innovative NTE from BT, offers N*64K • Clear channel, uncontended bandwidth, side effects of BT core IP etc • Product innovation rate might be limited by changes BT can make on 21CN platform, original Datastream non-real time etc

  10. Recap • No impact on PPCs – but side effects and like-for-like feature options? • Data to plan PPCs and MSAN/NGN interconnect – impact on OLO cost base, so drives OLO response to a SAN • Clear Ownership PPC, WES, BES/BPC, RBS and development of new products in PPC and WES not held up for 2 years
