  2. Requirements - Undertakings 4. Transparency 4.1 BT shall, for Partial Private Circuits, Carrier Pre-selection and DataStream: 4.1.1 within three months of these Undertakings taking effect, provide sufficient transparency ………………… 4.2 When AS provides in the future a TILLAP or a TILLBP, the costs attributable to those products shall form part of the cost stack for BT’s relevant Partial Private Circuits, and shall allow other Communications Providers to replicate commercially, from the point of view of their use of the TILLAP and/or TILLBP, relevant Partial Private Circuits, as set out in section 5.6. 5.5 AS shall also offer to provide to any Communications Provider within a reasonable time of a request the following and where relevant their handover products: a) TILLAP; b) TILLBP; c) Wholesale Extension Service Access Product; d) Wholesale Extension Service Backhaul Product; e) Wholesale End-to-End Ethernet Service; and f) Sub-Loop Unbundling and any relevant associated services. 5.6 When AS provides a TILLAP or a TILLBP, those products shall be made available to other Communications Providers in a manner that provides them with the opportunity to replicate commercially, from the point of view of their use of the TILLAP and/or TILLBP, relevant Partial Private Circuits. 5.10 AS will develop its Backhaul Products in accordance with sections 5.16 to 5.18. • 5.16 – Backhaul unconditionality, aggregation, resilience, daisy-chaining • 5.18 Where charges for a Backhaul Product which is an SMP Product are not required to be cost orientated, AS shall ensure that bandwidth related and distance related costs variations are among the factors taken into account in setting charges. • 5.46 The products and services supplied by Access Services5.46.1 AS will not supply any product to any other part of BT unless it also offers that product to other Communications Providers on an Equivalence of Inputs basis. This requirement does not apply to: • a) TILLAP and TILLBP; • b) such Associated Services as may be agreed with Ofcom; • c) any product where Ofcom agrees Equivalence of Inputs is not required for reasons of practicability or otherwise; • d) products listed in Annex 1 before Equivalence of Inputs is required to be provided in accordance with section 3.1; • e) any new product to the extent of any agreement by Ofcom that Equivalence of Inputs shall only apply from any particular date; • f) products relating to core network, duct, fibre and transmission between Core Nodes; • g) any other product or class of products that Ofcom and BT agree does not need to be supplied externally; • h) maintenance and provision carried out by AS field engineers, on behalf of a Communications Provider, on network termination equipment and internal wiring which is located on End-User premises; and • i) ‘handover products’ referred to in sections 5.4, 5.5 and 5.7.

  3. Requirements - Customers • Market factors • Access volume is heavily concentrated at 2Mbps and below • Substantial migration expected to Ethernet – price & technology-driven • Traditional services expected to decline • Customer interest demonstrated

  4. Implementation – the theory ppc O O O O O O O O O O O O O O O O O O O O NTE TillapePPC access TillbpePPC backhaul SDH T1 node SDH T1 node SDH node PoH EU • PPCs offer aggregation from multiple sites and speeds • Tillap & tillbp assume an idealised electronics structure • Alternative routing and diversity ignored for simplicity

  5. Implementation – the practice • Ancillary services • Aggregation – in what form if at all? • Cross-connection • Inter-connection • Separacy & diversity • Intercept with 21CN & changing network architecture • The network is not homogeneous • Many breakout scenarios • Not just bandwidth-related • Real network engineering issues

Where? Growth opportunities? Tillap; tillbp; tillap+tillbp? • Which ancillary services? • cross-connection, aggregation, colocation, inter-connection, separacy, diversity • Service levels & terms • Migrations • ppc -> tillap & tillbp; tillap & tillbp -> wes & bes • Contract & pre-development commitment • Pricing: element roce rebalancing; geographic pricing; incremental cost recovery
