1. FCP-Modify – High level Process & Illustrative Examples
Version 1 – 15th April 2013

2. May be considered for any existing ‘pre-FCP’ PoP type.
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’ PoP type.
Firm order acceptance is always subject to survey. For some PoPs, 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’ (CuC).
Lowers DC energy costs due to >95% power efficiency (cf 89%-92%)
Can help customers to prepare for consolidation of their LLU estates.

3. Definitions – Categorisation for APO
FCP-New Build is the provision of a new PoP in response to a customer order.
FCP-Modify is the means to upgrade an existing ‘pre-FCP’ LLU PoP 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 PoP.
FCP-Augment will entail re-engineering of an in-life FCP PoP to increase its spatial and/or maximum power capacity envelope beyond the original expected future maximum.
LLU-Regrade applies to any Non-FCP LLU PoP and encompasses changes of a minor engineering nature within the existing design limits of the relevant product type.

4. 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 PoPs 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.

The PoP following upgrade via FCP-Modify
All power now via Power Base. Old ac removed.
Capacity for up to 30 additional ties in PowerBase.
Customer is able to clear and re-use RSU3 due to recovery of their old DC system.

21. 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 CuC 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

22. Example 14 Hostel Bays (Type A and B)
“I want to exploit my Hostel Bay and add capacity. I need 8kW now and up to 10kW in the future. I want two more 600W x 800D RSUs each with a CuC 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 8kW / 3.6metres
FCP HDF
AC Supply to Hostel room continues to be used
Bay 2 Type B 4kW / 1.8 metres
CP ‘Z’ – no change

23. FCP-Refresh – Power capacity increase
Start
FCP PoP
LLUMS & Billing System
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 is advised of order completion via an itemised statement of new charges arising from the APO.
Inventory records updated & billing triggered.
Customer places APO quoting LLUC(s) and the required new ‘usable maximum power’ value required (xx.xkW).
Yes
Customer informed of power capacity situation and indicative timescale before an increase may become possible.
Openreach / EIPB APO Power capacity survey(s) undertaken
Enough ac power capacity for an increase? No
Finish

24. FCP-Augment (applies to in-life FCP PoP 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 PoP 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.

25. LLU-Regrades (‘Minor-works’)
In scope:
MCU-Max & Aux: 4.95kW to 6.6kW (rectifier infill)
B-Buss3: 4.4kW to 6.6kW (rectifier / battery infill)
Additional DC sub-distribution connected to existing DC system
Additional AC sub-distribution connected into existing AC system.
MCU1 to MCU2 (+1 rectifier & +5 HDF sub-racks + RSU#2 if space).
B-Buss7 Supplementary HDF rack
B-Buss7 to B-Buss3 downgrade
Inverter tower
Non-ESS to ESS transfer
Retrofit sub-meter.
HDF sub-rack provision into available space in or adjacent to the PoP.
Note: The above is not and exhaustive listing – further low-capex re-grade solutions of a minor engineering nature may be added.
