5. Introduction Slide 5 This best practice guide, provides Communications Providers (CPs) key information, on how to efficiently manage Left In Jumpers (LIJs) and understand the LIJ warnings, to help reduce avoidable charges during the ordering journey and reduce early life failures by needless network intervention. This guide also touches on the R2400 “Dummy” functionality, which gives CPs the maximum opportunity to reduce potential LIJ charges (current pricing can be found on the Openreach portal under LLU pricing) The guide is aimed at CPs business analysts, IT designers, product and process specialists. When followed, this guide should help to reduce the avoidable LIJ charging. This presentation aims to both raise awareness and give guidance on best practice around inventory management and order processes for Flexi Cease, when allocating tie pairs for their end user orders. The scope of this document provides coverage of the provision process and includes best practice for the Local Loop Unbundling (LLU) Metallic Path Facility (MPF) and Shared Metallic Path Facility (SMPF) Product(s) and is correct as of EMP R2400.

6. What is Flexi Cease Slide 6 Flexi Cease is a term applied to the Local Loop Unbundled (LLU) products (MPF) and (SMPF). Although the services are ceased there is no actual removal of Main Distribution Frame (MDF) jumpering, the line at this stage is in a status of ‘STOPPED’ and the tie pairs are in the state of Left in Jumpers (LIJs) A CP could submit a jumper removal order, after the cease is complete which would remove the MDF jumpers completely, the tie pairs would no longer be LIJ.

9. Information Terminology of LIJs and their locations Slide 9 Left In Jumper (LIJs): Means that, on completion of the cease request, the jumpers on the MDF will not be removed. The following terms will help you understand the terminologies associated with LIJs: Spare Tie Pair: Means a tie pair that is spare and does not have LIJs LIJs at Target : Means that the tie pairs associated with the address where the new service has been requested are in a LIJ state and owned by yourself. If this tie pair is not reused at its current location on an order response code 1884 will be sent. LIJs at Donor : Means that the tie pairs you supply for the provision address are currently in a LIJ state, routed to a different address. If this tie pair is used on an order to a different location to the current one response code 1885 will be sent. LIJs at Donor and Target : Means that the tie pairs you supply are in a LIJ state to a different address from the target address (LIJ at donor) and at the same time the tie pairs associated with the address where the new service has been requested are in a LIJ state (LIJ at target). If this tie pair is used on a order response code 1886 will be sent. Dummy (R2400): Used when you are uncertain of network against address routing if LIJs at target, Openreach will confirm in KCI 1.6 if target ties exist and belong to you.

10. Information LIJ Response Code And Warnings Slide 10 These are the existing response codes that serve as a final warning to CPs that they may incur charges for removal of LIJ ties. Response code XML templates can be found within the XML specification documents on the Openreach Portal

11. Information R2400 “DUMMY” Functionality Slide 11 R2400 has delivered an enhanced ordering journey, that enables CPs to use “DUMMY” within the order XML, resulting in Openreach completing the exchange and LIJ validations at “Routing Completed” KCI 1.6 stage. When a CP provides tie pairs on an order, it makes sense to return LIJ warnings after the routing step has been performed.This functionality gives the CPs the opportunity to maximise their re-use of their LIJs and minimise their exposure to LIJ charges. On Release R2400 deployment (MPF/SMPF) MPF and SMPF KCIs will contain the exchange (MDFSiteId) tag New KCI 1.6 for Dummy tie pair orders New LineStatus of “Routing Completed” for KCI 1.6 Amend tie pairs on Dummy orders to be placed after KCI 1.6 New Response Code 517 for KCI 1.6 LIJ warning Response Codes (1884/1885/1886) move from KCI 1 to KCI 2

12. Best Practice Process for Avoiding LIJ Charges Slide 12 The swim-lane process on the following slides outlines the best practice process for managing all ordering scenarios with LIJs (without using R2400 functionality).

13. EMP Communications Provider Best Practice For MPF Slide 13 Runs eMLC (on access line ID) to identify Target LIJs If eMLC has returned Target LIJs, CP should use the same in the order. Failure to use returned LIJs will create charges If there are no target LIJs, then run Tie Pair Checker Dialogue Service against the tie pairs you intend to use in your order If Tie Pair Checker indicates Donor LIJs, then charges will be raised if these tie pairs are used in CP order If CP does not wish to incur LIJ charges please ensure you re-use Target LIJs or supply spare Donor LIJs Based on eMLC and Tie Pair Checker response, CP is now ready to place the order Return eMLC response with or without Target LIJs No Target jumper recovery charges applied Return Tie Pair Checker response indicating whether the ties in question are Donor LIJs or not N/A No Donor or Target jumper recovery charges applied KCI Messages relayed to CP in correct sequence. Subject to correct usage of tie pairs, LIJ recovery charges will not be applied N/A Openreach engineer will jumper the tie pairs (as indicated on the order by the CP) and completes the FRAMES activity Openreach FRAMES Runs Address Match & MLPAReturn NAD key & any stopped linesN/A

14. EMP Communications Provider Best Practice For SMPF To An Existing Service Slide 14 Runs eMLC (on telephone number) to identify Target LIJs If eMLC has returned Target LIJs, CP should use the same in the order. Failure to use returned LIJs will create charges If there are no Target LIJs, then run Tie Pair Checker Dialogue Service against the tie pairs you intend to use in your order If Tie Pair Checker indicates Donor LIJs, then charges will be raised if these tie pairs are used in CP order If CP does not wish to incur LIJ charges please ensure you re-use Target LIJs or supply spare Donor LIJs Based on eMLC and Tie Pair Checker response, CP is now ready to place the order Return eMLC response with or without Target LIJs No Target jumper recovery charges applied Return Tie Pair Checker response indicating whether the ties in question are Donor LIJs or not N/A No Donor or Target jumper recovery charges applied KCI Messages relayed to CP in correct sequence. Subject to correct usage of tie pairs, LIJ recovery charges will not be applied N/A Openreach engineer will jumper the tie pairs (as indicated on the order by the CP) and completes the FRAMES activity Openreach FRAMES

15. Best Practice Best Practice for Inventory Management Slide 15 Below is a set of recommendations for our CPs to effectively manage their own inventory. Recommendation Manage tie pair inventory by recording jumpers in use, spare, or left in by using KCI 3 messages from the orders associated with the jumpers. Use Tie Pair Reconciliation Report (TPRR) to obtain Tie Pair details that you own. This is available via the Openreach Portal. Tie Pair Checker Dialogue Services and eMLC are also at hand to obtain the tie pair status and also MLPA to look at stopped lines for potential re-use. Check if you have any quarantine periods in place for reuse of your LIJs, consider any removal benefit.

16. Best Practice Best Practice for Inventory Management Slide 16 Below is a cropped example of a TPRR (Tie Pair Reconciliation Report). Tie Pair Reconciliation Report is made up of the following headers: CP_ID: This is your Duns ID MPF_SITE_ID: This is the exchange ID of the exchange the Tie Cable and Tie Pair terminate within TIE_CABLE_ID: This is the Tie Cable ID that the Tie Pair terminates on TIE_PAIR_NUMBER: This is the Tie Pair number SERVICE _ID: This is your Service ID that is related to your active/live services e.g. there should be one record for an MPF service and two for an SMPF service. LIJ_STATUS: This shows if the Tie Pair is in a left in status and will be set to either Y/N TIE_PAIR_STATUS: This field provides the Tie Pair Status and can be set to either S=spare N=not spare F=faulty COMMENTS: The comments provide basic information on the Tie Pair
