Wholesale Bitstream Solution Architecture. Figure 1: Overview of the Wholesale Bitstream solution architecture The NBI Wholesale Bitstream Products are delivered by means of an optical fibre connection directly from the End User premises to the Local OLT location and from there to the Regional PoH and onwards over a backhaul network to a National Point of Handover. This technical solution is a Fibre to the Home (FTTH) end-to-end ethernet Layer-2 product delivered using 10 Gigabit/s Passive Optical Network (XGS-PON) fibre. This network is deployed with a maximum Optical Distribution Network (ODN) split ratio of 1:32. At the End User premises it is terminated on an Optical Network Terminal (ONT) providing a standard ethernet termination for connection to the Service Provider CPE. From the PoH, the Wholesale Bitstream traffic is transmitted over the backhaul network to an agreed Service Provider Interconnect location. Details on the Interconnect types and locations are contained in the Interconnect Product Description and Interconnect Technical Manual which are available on the NBI website or via NBI Service Provider Account Manager where applicable. Further details of the design and specification of the Wholesale Bitstream products are contained in the product technical manual. Table D - Performance Parameters
