4. www.btwholesale.com Revised Annex E (AIT) Summary of Revised Artificial Inflation of Traffic (AIT) Annex E to the BT Standard Interconnect Agreement (SIA) Presentation to the BT Standard Contract Forum Erica Cumming, Commercial Lawyer BTW 20 February 2008

5. Revised Annex E (AIT) What is AIT?: AIT is “artificially inflated traffic” occurring on voice interconnect service. Annex E of the BT Standard Interconnect Agreement (SIA) allows call monies to be withheld where call traffic is suspected of being generated artificially (incl. potentially fraudulently). While the call traffic is being investigated Annex E permits the ONO to withhold money from the: - terminating network operator (TNO); or - (more commonly) transit operator (TO) - who then withholds it from the TNO. BT is the TO in 70+% of AIT cases, but may also be the ONO or the TNO. After investigation the parties decide whether the call traffic is AIT or not. If it is not then it is promptly paid to the TNO together with interest (under current and also proposed new provisions). If it is AIT it is retained permanently by the ONO and should be refunded to callers wherever possible. 5

6. www.btwholesale.com Revised Annex E (AIT) Need new AIT Annex E: Ever since the 2002 General Contract Review there has been ongoing work on a re-evaluation of the concept of AIT. Current definition of “AIT”: “A situation where the flow of Calls to any particular Revenue Share Service is as a result of any activity on or behalf of the party operating that Revenue Share Service disproportionate to the flow of Calls which would be expected from good faith commercial practice and usage of the network.” New forms of telephone scams constantly emerging, e.g.:  Missed calls from 070 and mobile number ranges, including displaying fake caller line identification (CLI) for the purpose of tricking recipients to dial the missed number.  Micro short duration calls designed to falsely trigger Call payments  Tromboning or routing calls outside the UK to increase Call charges These necessitate improved processes and a more relevant definition 6

7. Revised Annex E (AIT) Revised with industry: Revised Annex E was drafted in conjunction with industry (C&W, Virgin Media, Band-X, Vodafone, KCom, Thus and 3) who support need for new Annex E Aims of new AIT Annex E: Refresh the scope of AIT Annex E to better capture the fraudulent, misleading or unconscionable, types of call traffic and make the retention and investigations process simpler and clearer greater clarity of the roles and responsibilities of the parties and increase onus on ONOs to provide better supporting information: introduce tighter timeframes make the overall process more structured and expedient develop standard forms give clearer reasons and more detailed substantiations for retentions allow BT as transit operator to retain independently in specific circumstances provide a process where for transit the ONO and the TNO are in direct contact, however BT can only come out of the dispute process with the agreement of the TNO and the ONO. Clarify treatment of ported and hosted numbers Clarify dispute resolution options. Introduce an end date if AIT Dispute is not progressed by the TNO 7

8. Revised Annex E (AIT) New definition “AIT”: Definition wider but 01 and 02 geographic calls excluded as call charges too low to attract AIT activity Two limbs of definition:  1 st limb:Calls for benefit of a party connected to a telecommunication service as a result of activity by that party or on their behalf and  2 nd limb: Calling pattern disproportionate to pattern would expect from: - good faith usage; or - acceptable and reasonable commercial practice Not “good faith”/ “acceptable and reasonable commercial practice” if: customer is misled breach PhonepayPlus Code (unless “minor” under PhonepayPlus Sanctions Guide) activity intended to prevent billing system capturing necessary information 8

9. Revised Annex E (AIT) AIT Retention & Investigation timeline: day 11 st day of the calendar month after the date of the call traffic day 14A1 Retention Notice issued to TNO, explains “reasonable suspicion” of AIT day 26 AIT Call Data provided to TNO or else A1 Retention Notice withdrawn day 34 TNO issues Rejection Notice if objects day 49Dispute Notice issued to TNO (if not then deemed Withdrawn Notice) 5 days If Dispute Notice served then becomes AIT Dispute 5 days later & parties laterresolve using bilateral negotiation, ADR, mediation, expert determination or court – but up to parties to decide how to resolve. After 10 months of an AIT Dispute being declared: If the parties to an AIT Dispute have not: (a) agreed resolution in writing (b) agreed to commence a form of binding dispute resolution; or (c) initiated court proceedings- then it is deemed to be AIT and monies may be retained. This gives incentive to TNOs to investigate and resolve suspected cases of AIT whereas currently cases stay unresolved for many years Flip side is that ONOs cannot misuse the Annex E process because would be a breach of their obligation to act in good faith

10. Revised Annex E (AIT) Initiating A1 Retention Notice: Under the new Annex E provisions, in transit situations the A1 Retention Notice can be issued by:  ONO (as now) or (in future additionally by):  BT (but only in exceptional cases where only BT is aware of the AIT because it has AIT Data which ONO does not have access to) Information provided on A1 Retention Notice: Reasons for holding a “reasonable suspicion” of AIT (with reference to the definition of AIT) Estimated value of sums to be retained Estimated total duration and/or number of relevant calls Start and end dates when relevant calls were made Full dialled telephone number(s) - unless exceptional circumstances, i.e. informal/formal regulatory alerts or investigations or calling patterns which suggest a party is attempting to disguise AIT activity across a block of numbers 10

11. Revised Annex E (AIT) AIT Call Data: Detailed written explanation of why the AIT Call Data indicates AIT AIT Indicators: Retained former ones and added new ones to reflect new types of AIT More than RSS or PRS calls AIT Disputes: Current AIT Annex E provides for Arbitration, but problematic because AIT Disputes may involve three parties across two different SIA contracts with risk of two different Arbitration outcomes. Has not been popular or used New AIT Annex E does not proscribe any particular form of dispute resolution – it is totally up to the relevant parties. e.g. revised Annex E has flexibility for ONO and TNO to go for mediation – quick, cheap and decisive and don’t need BT there Standard of proof to permanently retain the AIT sums is a “strong and convincing suspicion” of AIT (whereas the initial retention only requires “reasonable suspicion”) 11

12. Revised Annex E (AIT) Implementation: Simultaneous adoption of new AIT Annex E for process to work. Many CPs have been involved in drafting and support the new AIT Annex E, provided it applies to all CPs from same date. Plan:  BT issue new AIT Annex E as part of the Reference Offer at end of February 2008 after briefing the whole industry on the new provisions, and issue a Supplementary Agreement to all CPs  Require signature to Supplemental Agreement by 1 April 2008. BT may refer to Ofcom as a dispute if any CPs do not sign in time and BT would look to Ofcom to deem that new AIT Annex E shall apply to all CPs  AIT Annex E will come into force when triggered by an industry-wide notification from BT 12

16. Revised Annex E (AIT) QUESTIONS?

17. Standard Contract Forum Consult21 Update on 21CN 20 th February 08

18. 21CN Plan Status BT is conducting a periodic review of the 21CN Plan, which has the benefit of reflecting on the experiences to date from Pathfinder and other testing activity. The review is focussing on three main areas: Early realisation of benefits of the move to 21CN for CPs and their end users Expansion of flexibility and choice for CPs of the 21CN plan Improving the levels of certainty of delivery to the plan. Whilst Broadband and Ethernet product deliveries are on track, the approach to Voice (and the new voice products) is the subject of ongoing discussion with CPs WBC trials continue, to enable an end of April launch

19. NGN CC / Interconnect Questions When will NGN CC be needed to convey NGN traffic? What volumes are needed at each Point of Service Interconnect (POSI) to make the service commercially viable? What are the relevant thresholds - volume of minutes or number of end users? Planning NGN CC connections under end user migration strategy? Where is the NGN CC service required? Is a national service required at launch (with inter-Metronode conveyance) or would a geographic roll-out better serve CP needs? If there is no significant end user voice migration for a time: How long before the commercially viable volumes are reached should CP service establishment inter-working tests be undertaken? Should we work directly towards the implementation of Replacement Charging Mechanism (RCM) to avoid the complexity and cost of the Interim Charging Arrangements?

20. Interconnect While the voice strategy is being determined, the Tranche approach to DLE interconnect route migration to VICs (virtual routes off the NGS switches) has been suspended. IN the meantime, route closures and growth are subject to “per occasion” bi-lateral discussions between BT and CPs. The Next Generation PSTN Interconnect (NGN Call Conveyance) product is due to launch in time for mass migration. BT and the potential triallist CPs are working on the testing programme (tests, location, timescales etc) to achieve this. The actual launch date is however subject to review, as the concept of Mass Migration is now affected by the elective approach to end user migration. The 1G Multi-Service Interconnect Links (MSIL) product, which is required to carry both broadband (WBC) and interconnect (NGN CC) services, has been launched.

21. Broadband The Wholesale Broadband Connect (WBC) product, delivering the faster broadband capability to end users on ADSL2+ access technology, is planned for launch at the end of April 2008, with the “Managed” version of this product, (WMBC) following immediately after. WBC plan is to launch with 5% coverage (some 84 exchanges) and achieve 50% coverage by April 09. BT brought forward CP involvement in WBC trialling, These Birmingham trials are now approaching the third phase of testing. IPstream will stay on 20CN, as will Datastream. The withdrawal of these products will be subject to consultation.

22. Pathfinder – Migration Pilot in South Wales The Bedlinog trial and end user feedback activity gleaned some very useful feedback. This trial ended on 14 th December. The date for the full re-load of both Wick and Bedlinog onto 21CN will be determined subject to test performance and upgrade paths to ensure the customer experience is optimised The scope of Pathfinder is subject to review as a result of the proposed approach to end user voice migrations Phase 1: 75k end users Phase 2: subject to discussion within Consult21

23. Consult21 Working Group Information Working GroupMonthly Key Information Network Structure A further release of the Network Inventory issued. Good progress being made on providing security with a workable process for CP’s to obtain datasets. Voice Line Control specification work continues (supports the WBCC and VLA voice products). Discussions on Standards related to any new interfaces required as a result of any new approach to delivering the 21CN objectives Systems & Processes Joint work continues with NICC B2B group. Since finalising the Trouble to Resolve(T2R) process work, focus is now on Lead to Cash (LTC). Interconnect & Portfolio Work is focussed on delivering improvements to aspects of the VIC product and finalising product specifications of the new PSTN Emulation interconnect product. Line Access Access products (VLA, WBCC etc) is an active debate within this WG, as is the proposed approach to voice services. Point to Point Continue to lead on the MSIL engagement. Now WG links with openreach Ethernet forum. Broadband Consultations issued on WBC downstream QoS and use of fibre.

24. Consult21 Working Group Information Working GroupMonthly Key Information Implementation & Migration Work is focussed on enabling Pathfinder restart. Broadband work is majoring on the WBC trial(s) and will also deliver the detail of migrating IPstream to WBC. End User Migration Communications Focus has recently been on ensuring that resellers are aware of 21CN, and the potential impacts on them and their customers. Discussion is increasing on broadband and corporate communication processes
