2. Tier 1 Pricing Principles

3. www.btwholesale.com To make your own calculations Operators can calculate their own Tier 1 prices by using information BT has made available on www.btwholesale.comwww.btwholesale.com The information to enable these calculations are held in several files as follows:- Postcode to Serving Exchange File (PSEF) - Contains all instances of a post code where BT is currently providing PSTN access to a site and therefore has already identified the true Serving Exchange for that site. Supplementary Post Code List - contains valid post codes not listed in the Postcode to Serving Exchange File. PPC Serving Exchange to T1 Node - lists all the BT Serving Exchange Node matched to the nearest Tier 1 node. DPCN Nodes 1141Codes - contains a list of all Digital Private Circuit Network (DPCN) nodes SDH Node list - contains a list of all SDH serving nodes. Tier 1 Node Aggregation – contains the aggregated Tier 1 Nodes Full details on using the above files to calculate PPC circuit distance is detailed in the PPC Circuit Distance Calculation ManualPPC Circuit Distance Calculation Manual

5. www.btwholesale.com Initial Order CP to BT Customer Contacts BT for PPC and supplies the following information to BT 1. Third party post code or Eastings and Northings. 2. The POH SDH/DPCN Node 3. Circuit Option BT enters details supplied by customer into PPC Pricing Tool. The Pricing Tool calculates the Trunk and Termination segment distance. The distance is then entered into the order handling system. At Firm Offer Confirmation (FOC) the circuit distance and circuit provision costs is given to customer. Start customer requires PPC

6. www.btwholesale.com Tier 1 Node Pricing Examples

7. www.btwholesale.com Notes on PPC Pricing Examples For circuit bandwidths from 64K to 960K, prices are based on the tier 1 node pricing distance between the third party BT serving exchange and the Digital Private Circuit Network (DPCN) node nearest to the point of handover. DPCN bearers are charged on the radial distance between the DPCN node and the BT SDH node. 1mbit –155mbit circuit prices are based on the tier 1 node pricing principle between the third party BT serving exchange and the BT serving node. CSH, ISH and 3 rd party infrastructure prices are for indicative purposes only. The customer can configure the Add-Drop Mux ( ADM) to meet their specific requirements. These examples are for illustrative purposes only and should not be used as the basis for any quotations – always consult the carrier price list for the most up to date pricing information. Circuits are shown from the 3rd party customer site to Point of Handover (POH) and onto the annex 2 operator’s network.

8. www.btwholesale.com Principles and Guidance Pricing is based on the 3 elements of a PPC circuit Big pipe” from an OLO network POH to the BT network (A end) The required bandwidth path across the BT network A local end path to your third party end users site (B end) Each element is priced for The connection charge and the rental charge Connection charge Infrastructure charges for 3rd party site, POH and circuit connection charge across the BT network. Excess charges as required at the 3rd party site and the POH Rental charge Local end fixed charges Main Link fixed charge + Main Link segment charges + Terminating segment charges + Optional Enhanced Maintenance charge Rental on POH infrastructure

9. Connection charge at 3rd party site Is this an existing or new 3rd party site? Is access required to Marconi Synchronous Hierarchy (MSH) network? Are batteries required? Choose Network Terminating Unit NTU or ADM, tributary cards and protection as appropriate for site Fibre working type and wavelengths are determined by BT on site survey Use Carrier Price list (CPL) section 8.02 to choose infrastructure as appropriate Use CPL section 8.06 for excess charges as required at 3rd party site Connection charge Use CPL section 8.02 for the circuit connection charges across the BT network Connection charge at POH Is this an existing or new POH? Is access required to DPCN or MSH network? Are batteries required? Choose ADM, tributary cards, fibre working,network access and protection as appropriate for site Fibre working type and wavelengths are determined by BT on site survey Use CPL section 8.01 (CSH), 8.01 (ISH) or 8.01 (ISH- Extn) to choose infrastructure as appropriate Use CPL section 8.06 for excess charges as required at POH www.btwholesale.com Principles and Guidance

10. www.btwholesale.com Principles and Guidance Maintenance charge Use CPL section 8.03 for the appropriate circuit local end fixed charge at 3rd Party end Use CPL section 8.03 for the circuit main link fixed charge at 3 rd Party end Calculate the terminating segment and the main link segment distances using files available on BTwholesale website. Use CPL section 8.03 to calculate charges before and after the SDH Tier1 breakpoint Enhanced Maintenance charge (Optional) Use CPL section 8.03 to calculate charges based on the total radial distance calculations. POH Rental Use section 8.01 (CSH), 8.01 (ISH) or 8.01 (ISH- Extn) for the appropriate rental charges on infrastructure provision and 8.01 part 1.6 in respect of the efficient use of PoH Infrastructure rental.

13. Efficient / In-Efficient POH Rental Charges In the Leased Line Charge Control published 2 July 2009 Ofcom directed BT show separately the PoH charges that historically have been embedded within PPC Local End Charges and introduce a cost recovery mechanist that would incentivised migration to new aggregated PoHs. Under this approach, circuits handed over new PoHs would not attract the separate new PoH charges and incentivised CPs to migrate to the new efficient PoH as it would allow them to reduce (and ultimately avoid) the new PoH rental charges. – New rental charges on PoH Infrastructure where the ADM is considered to be Efficient PoH (SMA-1; SMA-4 & SMA-16). For CSH & ISH Extn PoH there will be an additional Bearer Charge (CPL B8.01 part 1.6 PoH Rental Charges refs) –Third Party PoH fixed Charge associated to circuit rental where the circuit is provided using in-efficient ADMs (non-PPC ADMs; 4x2 & 16x2) CSH & ISH Extn PoH = ADM rental + ADM PoH rental + Bearer charge = ISH PoH = ADM rental + ADM PoH rental charge Circuit rental includes the 3 rd Party rental charge where it is provided using in- efficient PoH i.e. 4x2; 16x2 etc. Where the PoH is efficient the circuit rental will not include the 3 rd Party PoH fixed charge Efficient Circuit Rental = Local End fixed charge + Main Link total charge In-Efficient Circuit Rental = Local End fixed charge + 3 rd Party PoH fixed charge + Main Link total charge.

Each path has a terminating and trunk element, the average is found by adding the trunk elements of paths A and B together and dividing by two, then adding the terminating elements of paths A and B together and dividing by two. This gives an average trunk and terminating element for paths A and B; this is added to the trunk and terminating elements of the Drop and Continue Interworking (D&CI) path, to give a total trunk and terminating distance charge for the PPC PP V2 Circuit.

No extra Excess Construction Charge will be applied to a Standard delivered circuit where the cabling required is upto and including 3010 metres. Where it requires more than 3010 meters to deliver a standard delivered circuit, the amount of cable over the 3010 metres will be charged at the rate detailed in the Openreach Price List. Where the circuit requirement is for non-standard delivery i.e. for resilience purposes, the whole amount of cable will be charged.
