Overview

The NGA Tail Extension Service (TES) is an ancillary service that allows you to aggregate UFB Bitstream services from multiple UFB candidate areas on a single UFB handover connection service located at a Regional Point of Interconnection (POI).

An NGA tail extension allows you to serve multiple NGA coverage areas from a single (regional) NGA handover connection. As we have five regional hubs, in Auckland, Hamilton, Wellington, Christchurch and Dunedin, you can provide national NGA service with at least one handover in each hub.

The tail extension service is made for service providers who require local, regional or national transport of customer traffic between their network point of presence (POP) sites, or between their POP site and a Chorus handover point where aggregated access services have been presented for handover.

You can also use this service to access tail traffic from a remote Chorus aggregation exchange where it does not make commercial sense to establish a handover link at the remote exchange.

Benefits

Benefits to retail service providers

  • Reach: we deliver fibre in areas where you have no local point of presence. An NGA tail extension is not an any-to-any construct. An NGA tail can only handover at the local point of presence or at a regional point of presence associated with the local coverage area.
  • Flexibility: the Tail extension service works across all NGA areas (UFB, non-UFB, RBI). You can also select the tail extension service for handover at the local point of presence for the following services: NGA Evolve, NGA Business, NGA Business Premium, and NGA voice.
  • Optimisation: this allows you to handover each service locally or regionally. You can even choose differently, for voice and data.
    A UFB handover connection requires 27 points of interconnection to provide service nationally; with tail extension you can do it with five. Tail extension divides New Zealand into five regions, where each region acts as a ‘super’ coverage area (Auckland, Hamilton, Wellington, Christchurch and Dunedin).

Other benefits

  • Reduced set up costs: minimise infrastructural setup costs within smaller and more remote coverage areas.
  • Support competition: this service encourages NGA take-up in smaller and more remote NGA coverage areas, by supporting competition within smaller and more remote NGA coverage areas, and lowering the barriers to entry for smaller and secondary service providers.
