FCP-Modify High level Process Illustrative Examples

FCP-Modify – High level Process & Illustrative Examples Gary Williamson Openreach LLU Technical Development Manager Version 1 – 15 th April 2013

Introduction § FCP-Modify is about getting more from existing LLU infrastructure through rejuvenation and in-life upgrade: § May be considered for any existing ‘pre-FCP’ Po. P type. § Firm order acceptance is always subject to survey. For some Po. Ps, physical expansion may not be possible due to the presence of surrounding equipment belonging to other customers or BT. Openreach will offer what is possible for customer consideration. § Can help improve service continuity through greater power resilience. § Offers more for the customer – eg ‘Customer Use Cabinet’ (Cu. C). § Lowers DC energy costs due to >95% power efficiency (cf 89%-92%) § Can help customers to prepare for consolidation of their LLU estates.

Key Points 1. It is important that: 1. Prior to APO placement there is a customer / Openreach dialogue to agree and document the customer requirements to be met. 2. Following receipt of an APO in which multiple similar Po. Ps are to be upgraded, the work is undertaken as a programme. This will help to ensure consistency of delivery for the customer. 3. Customers have a person who is the primary point of contact for FCP-Modify orders over the end-to-end delivery process. 2. A ‘rack face’ map will be created for added cabinets and added rack spaces. This will help the required positions of ethernet fibre and equipment to be thought through and defined by the customer. 3. In some cases the APO survey will find that there is insufficient suitable space and/or ac mains power capacity to satisfy the customer’s requirement. Openreach will seek to offer an alternative based on what appears feasible.

Definitions – Categorisation for APO § FCP-New Build is the provision of a new Po. P in response to a customer order. § FCP-Modify is the means to upgrade an existing ‘pre-FCP’ LLU Po. P such that is subsequently treated as an FCP installation for billing and future upgrade path purposes. § § § Will always include provision of at least one new FCP DC Power System. Will always replace any existing Openreach maintained DC system(s). Is not offered in ‘AC Only’ form. May include additional rack space units (RSUs), Customer Use Cabinets and HDF racks. Is always subject to survey for space and ac power supply capacity reasons. Is always the subject of customer requirements document produced by the Openreach LLU Technical Development Team for customer approval and having an solution code. § FCP-Refresh applies to an existing FCP installation for the incremental increase or decrease of power capacity and/or the provision of additional features within the original physical footprint / expected future maximum power envelope (eg Add an HDF / HDF sub-racks, supply and install a Customer Use Cabinet). Does not entail re-engineering of the Po. P. § FCP-Augment will entail re-engineering of an in-life FCP Po. P to increase its spatial and/or maximum power capacity envelope beyond the original expected future maximum. § LLU-Regrade applies to any Non-FCP LLU Po. P and encompasses changes of a minor engineering nature within the existing design limits of the relevant product type.

Customer Requirements Definition The embedded document is the blank template to be completed for each new customer requirement that arises. One document may apply to many or few LLU Po. Ps of a given type. Dialogue with the customer may entail a degree of iteration as actual requirements are confirmed and the associated indicative pricing is understood. Once agreed, a PDF version of the Customer Requirements Definition paper will be stored and made available for use by the Openreach Plan & Build and EIPB teams. Each approved requirement will result in a “Solution Code”. The customer will then be able to place APOs quoting the solution code on one or many occasions.

FCP-Modify Pre-build process Dimensioning detail provided for LLUMS ‘wizard’ Customer & Openreach SRM / LLU tech team discuss and agree the customer’s requirements. LLU Technical Development Team produces LTDP document (PDF) defining the customer requirement and indicative pricing. Document is given an solution code and published internally once agreed with the customer, EIPB and the APO Team. Solution Code at ‘Agreed for APO’ status is notified to customer to enable APO placement Customer places APO quoting the relevant Solution Code Equipment layout issued Openreach / EIPB APO survey(s) scheduled. Yes Proceed to order delivery planning. Customer confirms firm order? No Bill applicable charges & Finish Solution recorded and published internally. Use relevant solution document APO survey work is undertaken and the results with floorplans are returned to the Openreach P&B team prepares an ‘Art of the possible’ survey response for technical sign-off. An Openreach response is then returned to the customer for consideration

FCP-Modify – Delivery Planning Start Delivery planning for firm build order(s) Job completion QA and handover documentation into Openreach P&B. PIRM updated. MUA RFI date(s) confirmed Recovery of redundant equipment is undertaken in accordance with agreed scope of works. New equipment installation date(s) confirmed Changeover activity is undertaken to transfer customer power loads onto the new FCP power system(s). Customer confirms service is OK Delivery Manager liaises with customer to agree installation and changeover date(s). Confirms work activities involved and roles. On-site installation work is undertaken up to the point of changeover from old to new. On-site delivery – a virtual single visit engineering undertaking Handover Pack issued to customer. Customer Handover – virtual or attended. Billing activity undertaken inventory and verified Order is complete. Finish.

Example 13 Bespoke Co-location Rooms Start point would be a review of room usage and electrical supply design check. FCP-Modify would provide Power-Base hardware and, as required, RSU / HDF and Cu. C facilities. Note – different commercial terms apply for bespoke rooms. BT AC mains supply to room. Typically via ESS. Originally designed for customer specified max power load. FCP-Modify design would review ac capacity to room to ensure correctly rated supply. May need to include some ventilation / cooling based on heat density. Customer LLU equipment – incl DC power and UPS

Example 14 Hostel Bays (Type A and B) “I want to exploit my Hostel Bay and add capacity. I need 8 k. W now and up to 10 k. W in the future. I want two more 600 W x 800 D RSUs each with a Cu. C to hold my new equipment. I also need an HDF for up to 54 new ties”. As a result, the Openreach survey and design offers a solution that looks like this. CP ‘X’ – FCP-Modify upgrade Bay 1 Type A 8 k. W / 3. 6 metres FCP HDF AC Supply to Hostel room continues to be used Bay 2 Type B 4 k. W / 1. 8 metres CP ‘Z’ – no change

Annex 2 ‘FCP-Refresh’ high level APO process ‘FCP-Augment’ ‘LLU Regrade’ Further work is to be undertaken on these.

FCP-Refresh – Power capacity increase Start FCP Po. P Customer pro-actively requests increase in ac power supply capacity from initial maximum power to a higher value not exceeding the ‘expected future maximum power’ stated at original build order. Where FCP DC system is present alarm settings are changed to reflect the applicable new maximum load current (from dimensioning tool). EIPB / FE D/L assumed until PIMMS remote config eliminates need for site visit. Customer places APO quoting LLUC(s) and the required new ‘usable maximum power’ value required (xx. xk. W). Customer is advised of order completion via an itemised statement of new charges arising from the APO. LLUMS & Billing System Inventory records updated & billing triggered. Yes Openreach / EIPB APO Power capacity survey(s) undertaken Enough ac power capacity for an increase? No Customer informed of power capacity situation and indicative timescale before an increase may become possible. Finish

FCP-Augment (applies to in-life FCP Po. P that originated as a new build or via FCP-Modify). • Process would be similar to FCP-Modify and begin with a customer requirements definition exercise to ensure that the need / indicative pricing is documented and agreed. • APO placed as the customer’s authority to proceed. • APO survey would be undertaken for each Po. P in scope. • Response to customer based on ‘art of the possible’. • Customer firm order decision. • Delivery planning, date setting, installation, QA. • Handover to customer. • Billing & inventory.
