Core Small Business Fibre Service

6. The core bitstream services provided as part of the Small Business Fibre Service are as follows:
7. One Access-EVPL, consisting of:

  *  **(a)** A single 802.1q VLAN on a designated UNI on the ONT at the End User Premises or Service Provider Premises or NBAP (as applicable).
  *  **(b)** A single 802.1ad VLAN (Service VLAN ID/ Customer VLAN ID) on the E-NNI at the local or, with NGA Tail Extension, regional POI.
  *  **(c)** A QOS bandwidth profile that describes how traffic is carried between these points.
2. Bandwidth overhead for Low Priority to compensate for higher protocol encapsulation overheads. This bandwidth overhead does not guarantee End Users will experience the headline speed as their experience is dependent on a number of external factors including, but not limited to, End User applications and local network, the Service Provider network and location of the content they are accessing.

7. The Small Business Fibre Service includes the options, exercised by Service Request, to:
8. Set the UNI as a tagged or untagged interface.
9. Enable Circuit ID insertion for PPPoE or DHCPv4 as follows:

  *  **(a)** Off – Product Instance ID will not be inserted in any frames;
  *  **(b)** PPPoE – Product Instance ID will be inserted into the Remote Station ID; or
  *  **(c)** DHCP – Product Instance ID will be inserted into the DHCPv4 Option 82 Remote ID field;
3. Specify the following attributes per Access-EVPL:
  1.  **(a)** The Access-EVPL E-NNI;
  2.  **(b)** The E-NNI S- C-VLAN Identifier; and  

If these are not specified then the default values will be assigned by the LFC;

4. Enable Tail Extension Service as an Ancillary Service. The Tail Extension Service allows a Bitstream Service (Access-EVPL or Voice-EVPL Service) to be delivered to a POI outside the End User’s local UFB Coverage Area.
5. The Tail Extension Service for an Access-EVPL or Voice-EVPL service is requested by selecting an E-NNI located outside the End User’s local UFB Coverage Area as part of a Connect, Move, Transfer or Modify Service Request;
6. If the UNI is set to untagged:
  *  **(a)** Untagged frames sent from the End User are 802.1q tagged and marked as Low Priority;
  *  **(b)** Tagged frames sent from the End User are treated as set out in 3.7.7 below; and
  *  **(c)** 802.1q tags will be removed from downstream frames and presented as 802.3 Ethernet frames at the UNI.
7. If the UNI is set to tagged:
  1.  **(a)** Frames sent from the End User that do not have 802.1q tags will be tagged and marked as Low Priority;
  2.  **(b)** Tagged traffic sent from the End User or Service Provider are treated as follows:
    *  **(i)** Frames tagged with PCP = 5 will be treated as High Priority.
    *  **(ii)** Frames tagged with PCP = 0 will be treated as Low Priority.
    *  **(iii)** Frames tagged with PCP = 1, 2, 3, 4, 6 or 7 will be remarked as PCP 0 and treated as Low Priority.
    *  **(iv)** Frames will be treated as follows:  

EIR ≥ 0

Policed at ingress based on CBS/EBS

| Queued and weighted fairly under congestion conditions

Frames classified as EIR dropped first

High Priority| CIR ≥ 0

EIR = 0

Policed at ingress based on CBS

| Strictly prioritised

• (v) Downstream traffic class is determined using the s-tag PCP setting although it is recommended that both the s-tag and c-tag is set to the same value.

8. The following initial Service Templates are available consisting of a Baseband Service with one instance of the ATA Voice Service and one Access-EVPL Bitstream service as follows:

  1.  **[1]** The ATA service is as described in the ATA Voice Service Description except that the High Priority frames are tagged with PCP 5.
  2.  **[2]** The headline rate is the Layer 2 bandwidth prior to the addition of the overhead described in section 3.6.2.
  3.  **[3]** Low Priority ‘Peak Information Rate’, which is the headline rate plus the bandwidth overhead described in clause 3.6.2, is the sum of Low Priority CIR and Low Priority EIR.
9. Small Business Fibre Service Templates are primary, i.e. include Baseband. A primary Service Template does not require the End User connection to consume any other Service Templates in order for the service to be provided.
10. A Secondary Service Template can be added as an additional service to an End User who is already consuming a Small Business Fibre Service Template. The Small Business Fibre Service Levels only apply to the Small Business Fibre Service Template.
11. The Small Business Fibre Service has similar characteristics to the other services within the UFB family of Bitstream services as identified below:

The Bandwidth options for each Bitstream Service are detailed in appropriate Bitstream Service Description. Clause 3.7.8 above lists options for Small Business Fibre and further options can be developed using the Product Development Process.

12. All Small Business Fibre Services (Access-EVPLs) on a UNI must belong to the same Service Provider and must connect to an E-NNI belonging to that Service Provider. However each Small Business Fibre Service can connect to a different E-NNI at the same or different POI within a Coverage Area.
13. The sum of High and Low Priority traffic profiles of all services delivered at a UFB Handover Connection Service can exceed the UFB Handover Connection Service line rate. If there is insufficient line rate to deliver the traffic then  

frames will be randomly discarded, based on their Class of Service precedence, and Service Levels for that Class of Service do not apply. It is therefore the Service Provider’s responsibility to shape and queue traffic appropriately.
Operations, Administration and Maintenance

8. The Small Business Fibre Service will support Service Provider remote access to the ONT via a service management gateway for appropriate management.

9. The Small Business Fibre Service will support Ethernet Service Operations and Maintenance (OAM) for service integrity testing, fault diagnostics and performance measurement using ITU Y.1731. OAM capability will be phased in as the functionality is developed and deployed in scale and may be updated or amended by the LFC from time to time.
   Service Requirements

10. To use the Small Business Fibre Service the Service Provider must have the capability to access and interconnect with it, by one of the following:

11. co-locating Service Provider equipment at the POI using the UFB Handover Connection Service and Central Office and POI Co-location Service;

12. connecting to third party co-location space at the POI using the UFB Handover Connection Service, and with the third party taking the Central Office and POI Co-location Service;

13. connecting to a backhaul service at the POI; or

14. by using the Direct Fibre Access Service to connect to Service Provider equipment at a remote location within the Central Office area.
    The location of the POIs is detailed in the Operations Manual appendices.
    Additional Service Characteristics

15. The technical specification of the Small Business Fibre Service is set out in Appendix B.

16. The LFC will provide certain support and other assistance as part of the Small Business Fibre Service including:

17. an automated facility for Service Requests;

18. an automated facility for fault notifications; and

19. a tool to assist the Service Provider in determining the location and availability of the Small Business Fibre Service (pre-qualification), each as more particularly set out in the Operations Manual.

20. The Small Business Fibre Service specifically excludes:

21. the UFB Handover Connection Service;

22. provision or maintenance of any cabling or connection or active device:

  *  **(a)** beyond the Service Demarcation Points described in clauses 4.1 and clause 5.1; and
  *  **(b)** between the jack terminating the LFC provided Fibre Lead-in and the ONT where that cabling or connection is not provided by the LFC and the LFC has not agreed to take responsibility for that cabling or connection;
3. configuration, monitoring, operation, on-going support or maintenance of Service Providers’ or End User’s applications, equipment or networks; and
4. supply of AC mains & UPS power, accommodation space, heating, ventilating, and air conditioning and facilities at the POI or End User Premises or Service Provider Premises or NBAP (as applicable).

Service Demarcation

Service Demarcation Point at End User Premises or Service Provider Premises or NBAP (as applicable)
The Service Demarcation Point at the End User Premises or Service Provider Premises or NBAP (as applicable) is the 100/1000Base-T UNI on the ONT. The Small Business Fibre Service excludes the End User Premises or Service Provider Premises or NBAP (as applicable) wiring. If a fault reported by the Service Provider is found to be caused by the End User Premises or Service Provider Premises or NBAP (as applicable) equipment (CPE) or the wiring at the End User Premises or Service Provider Premises or NBAP (as applicable) beyond the Service Demarcation Point, then the Service Provider may be charged the “No fault found” Ancillary Charge in the Price List. Note the wiring should comply with the industry standard Premises wiring requirements which are available at www.tcf.org.nz.

Service Demarcation Point at POI

Where no Tail Extension Service is used, the POI Service Demarcation Point is:

1. The physical Service Demarcation Point is the MOFDF in the Local POI, which is part of the UFB Handover Connection Service, and
2. logically, the single S-VLAN per Access-EVPL or Voice-EVPL on the E-NNI at the Local POI, which is part of the UFB Handover Connection.

Where Tail Extension Service is used, the POI Service Demarcation Point is:

1. The physical Service Demarcation Point is the MOFDF in the National POI, which is part of the UFB Handover Connection Service, and
2. Logically the single S-VLAN per Access-EVPL or Voice-EVPL on the UFB Handover Connection located at the National POI.
3. The logical demarcation between the Small Business Fibre Access service and Tail Extension Service is the middle of the Ethernet Aggregation Switch at the local POI. There is no physical demarcation point and the E-AVPL is provisioned as a single entity

Service Prerequisites

1. The UFB Handover Connection Service is a separate service and is a prerequisite to the supply of the Small Business Fibre Service i.e. Service Provider’s must first purchase and then continue to maintain a UFB Handover Connection Service at all times while taking the Small Business Fibre Service.

LFC and Service Provider Responsibilities

Other LFC and Service Provider responsibilities are detailed in the General Terms and the Operations Manual.

Fibre Diversity

• The Small Business Fibre Service provides a single service instance at the End User Premises, Service Providers Premises or NBAP (as applicable).
• Diversity for Small Business Fibre Service is limited to a second or subsequent instance of the Small Business Fibre Service and does not include route diversity or Central Office diversity. A diverse lead-in between the Fibre Access
• Point and the Premises may be available as an option for some but not all Premises. Standard Installation Charges and Service Levels do not apply to the provision of the diverse products that involve diverse access to the End User
• Premises or Service Provider Premises or NBAP (as applicable). Each instance of the Small Business Fibre Service, primary and diverse, will be treated as an individual line for the purpose of availability Service Levels.

Small Business Fibre Service Levels

• Service Levels for both the Layer 1 and Layer 2 components of the Small Business Fibre Service are set out in the Service Level Terms for the Bitstream Services.
• It should be noted that the Small Business Fibre Service is subject to the Enterprise Service Level for Fault Restoration as described in the Service Level Terms for the Bitstream Services.

Appendix

Appendix A – Diagram

This is a generic diagram showing the standard configuration and Service Demarcation Points. It is not intended to represent every situation or detailed physical architecture. The following points should be noted:

• The Small Business Fibre Service and pricing applies from the UNI to the logical demarcation point at the local POI.
• Service Levels (availability, network performance) apply from UNI to the E-NNI at the local POI.
• The tail extension service, service levels and pricing applies from the local POI to the E-NNI where the service is handed over.
• Access node and aggregation interconnection may use redundant links to meet Service Level requirements.

The Bitstream services support simultaneous delivery of multiple Service Templates from the same or multiple Service Providers as follows:

• Multiple Access-EVPLs can be delivered to the same UNI.
• A Voice-EVPL can be considered an Access-EVPL with an ATA Voice port at the End User interface. The class and bandwidth characteristics of this Access-EVPL are optimised for voice.
• All services delivered to a UNI must belong to the same Service Provider but can be mapped to the same or different E-NNIs.
• The initial Small Business Fibre Service Templates contain a single Access-EVPL and one ATA Voice Service.
