4 1 Introduction 1.1 Overview The Baseband (non FTTH) Service enables the delivery of PSTN analogue telephony services over a range of access technologies such as copper, PCM, IP and radio systems from the end customer to a service provider. When ordering UBA on the same copper pair as Baseband Copper or Baseband IP you must be the same for both services. Where Baseband Copper or Baseband PCM is an input service to Telecom POTS then UBA and POTS can have different service providers. This enables the customer to take a bundle of UBA with resold POTS, which we have an obligation to supply under the Open Access Deeds of Undertaking. 1.2 Updates This product user guide is subject to change from time to time and will be updated to reflect changes as new developments are made. Any specific technology mentioned in this document is current as at date of issue and is for guidance purposes only. We reserve the right to adapt the technology employed to deliver the Baseband service. 1.3 Relationship with other documents This document outlines the operational functioning of Baseband. Baseband can be offered in conjunction with UBA and VDSL. When read in conjunction with the respective product user guides, this document outlines the operational functioning and description of UBA with Baseband and VDSL with Baseband. Commercial terms and conditions are recorded in the Chorus Services Agreement (CSA). This document does not constitute an offer to provide Baseband. A capitalised term in this product user guide has the meaning given to it in the Baseband (non FTTH) Service Description. 1.4 Intellectual Property We owns all copyright and all other intellectual property rights in this document. 4 Baseband (non FTTH) product user guide Sept 2016

5 2 Product Description 2.1 Introduction Baseband (non FTTH) service is categorised into the following product variants; Baseband Copper: Where a copper path exists between your customer s ETP and your handover point in the local exchange. The copper path can be directly from the local exchange to the ETP or transverse via an active cabinet. Baseband IP: Where a copper path exists between your customer s ETP and our Digital Subscriber Line Access Multiplexer (DSLAM). At the DSLAM voice frequencies are converted into a bitstream service and delivered to you on a Virtual LAN at a handover connection at the first data switch or backhauled using the Baseband IP backhaul service to our Point of Interconnection (POI) in one of the five regional service areas; Northland Auckland, Central North Island, Lower North Island, Upper South Island and Lower South Island. Baseband IP is intended to replace Baseband PCM over time and provides a stepping stone from switched voice to Voice over IP. Baseband PCM: Where a digital transmission system (mostly pulse code modulation) is used between the local exchange and the cabinet. Voice frequencies from an end customer s ETP are multiplexed on to the digital transmission system and delivered to your handover point. Baseband Remote: Where Pair Gain, Customer Multi Access Radio (CMAR) or Country Set systems are used to provide connection to your customer s ETP when there is no end to end copper path. Baseband PCM is available at distribution (or active) cabinets with PCM systems from the local exchange. Baseband Remote is available where we has deployed Pair Gain, CMAR, and Country Set equipment. Currently, Baseband PCM and Baseband Remote are only available as an input to Telecom POTS. Where we is unable to make Baseband PCM available to a service provider from a distribution cabinet with PCM systems from the local exchange, we intends to make available Baseband IP to you. This product user guide only focuses on Baseband Copper and Baseband IP. See the Baseband (non FTTH) Service Description for further information on Baseband PCM and Baseband Remote. Baseband Copper and Baseband IP can be provided to your customer in conjunction with UBA or VDSL over the same copper pair. 2.2 Baseband Copper description 5 Baseband (non FTTH) product user guide Sept 2016

6 Baseband Copper allows access to the voice frequency on a copper pair from your HDP in the local exchange through to the ETP. Baseband Copper is only intended to support a voice service. To connect from the HDP in the local exchange you must also have in place UCLL Colocation or Exchange Space. You must comply with PTC 190 Requirements for 0-4 khz systems for connection to metallic copper and PTC 200 Requirements for Connection of Customer Equipment to Analogue Lines. See the Baseband (non FTTH) Service Description for requirements if we replace PTC 190 and PTC 200. If your equipment causes impairment or interference to another service that breaches PTC 190 or PTC 200 then Baseband Copper will be suspended and you will be liable for any investigation costs. Baseband Copper can be used to support Basic Rate ISDN. Service providers can use frequencies from 0 80 khz when connected to Baseband Copper. ISDN BRA is incompatible with UBA or VDSL and is only supported on standalone Baseband Copper without any derived systems for pair gain. Very long Baseband Copper lines may require you to use alternative voice equipment at the local exchange to power these lines. They have greater than 10dB loss at voice frequencies and have range extending techniques such as loading coils and battery boosters employed to allow a cleaner voice frequency signal at the ETP.

7 The Baseband Copper service is only available to a service provider where it ll be the only service taken over a particular copper line, or where the only other service being taken by a service provider in conjunction with the Baseband Copper service over the relevant line is a UBA service (that we supply). It cannot be supplied to you over a copper subscriber line where the UCLL service or sub-loop UCLL service is also being supplied by us. It is only available on exchange-based lines and on those lines that are connected to a distribution cabinet that are notified by us to you via our website TENURE We ll notify you when Baseband Copper is not available either on a standalone basis or in conjunction with the UBA service on certain exchange-based lines and on certain lines which are cabinetised. In addition, we ll also notify you of the reasons for nonavailability, which may extend to include the following: the absence of equipment catering for the UBA service at the distribution cabinet, or the physical hard wiring of the broadband equipment to the voice equipment, makes the provision of the Baseband Copper service in combination with the UBA service unfeasible; the distribution cabinet, which does not have a copper connection to the exchange, does not support the Baseband Copper service; the copper feeder between the exchange and the distribution cabinet, which is only used as an access copper bearer for the equipment in the distribution cabinet, does not support the Baseband Copper service; certain other engineering purposes (eg order-wire) prevent the delivery of the Baseband Copper service from the distribution cabinet; the distribution cabinet has limited capacity on the copper feeder and does not support the Baseband Copper service SERVICE PROVIDER HANDOVER POINT The Baseband Copper service is delivered from the MPF side of the HDP block on the MDF. This does not preclude the connection of the MPF to our equipment between the exchange entry point and the HDP block. Where you take the Baseband Copper service in conjunction with the UBA service, the low frequency connection that forms the Baseband Copper service will traverse the tie cables between the MDF and the DSL splitter before appearing at the HDP block. To avoid doubt, any Tie Cables used to connect to and from the DSL splitter fall within the scope of the Baseband Copper service and will not be charged as tie cables connecting the HDP block to your equipment END CUSTOMER HANDOVER POINT The Baseband Copper service is delivered to the ETP at the end customer s building. 7 Baseband (non FTTH) product user guide Sept 2016

8 It excludes premises wiring. Either you or your customer will be responsible for customer premises equipment (CPE) and wiring beyond the ETP. You should (but are not obligated to) ensure that TelePermit requirements (available at and the Code of Practice for Residential and Small Office Premises Wiring (available at are adhered to TELEPHONE SERVICES You re responsible for end customer requirements related to the telephone service, including items such as numbering, emergency services contact, call signalling, call transportation and value added services such as call diversion, caller number display, messaging SPECIFICATION The parameters of Baseband Copper are defined for the MPF from the MDFDF (SLES) to the cabinet DF and from the cabinet DF to the ETP (sub-loop UCLL) When testing the parameters, Baseband Copper must be tested in isolation from cabinet wiring and equipment and from your wiring and equipment. Parameter (note 2) Parameter value (taking account of notes 1 to 2) Minimum insulation resistance between conductors 100k Ohms Minimum insulation resistance between conductor and earth 100k Ohms Table 1 Baseband Copper Line Parameters Note 1: The Sub-loop Extension Service MPF will be categorised faulty if any measured resistance is below the parameter values. Note 2: Any measurement made with respect to earth will be made using the earth at the exchange MDF or cabinet DF site as appropriate. 2.3 Baseband IP description Baseband IP converts an analogue PSTN-compatible 2-wire end points media to SIP media at our DSLAM. The SIP media is then delivered from the DSLAM as Bitstream over VPLS to your handover connection within the same region. The handover connection can be at the first data switch or backhauled to a handover connection at a separate Point of Interconnection (POI) with in the same region. The 8 Baseband (non FTTH) product user guide Sept 2016

9 backhaul to the remote handover connection will consume tail extension from the first data switch to the designated handover connection. Our POIs for Baseband IP are the same as for Enhanced UBA first data switches. There are five regions corresponding to the five regional Ethernet networks: Northland Auckland, Central North Island, Lower North Island, Upper South Island, and Lower South Island. The region the first data switches are in is provided in the Baseband IP Tail Extension spreadsheet on our website. Figure 2 Baseband IP and UBA from a cabinet TELEPHONY FEATURE SUPPORT The Baseband IP access provides the following telephony feature support: 2-Wire analogue lines G.711 A-law Codec with 10ms packetisation SIP simple mode configuration (also known as tightly coupled in the ETSI TSPAN TS ) NZ PSTN tones & cadences Fax and low-speed modem support Hook-switch Flash support (for 3-way calling, call waiting, call transfer, call hold) CLIP / CLIR Message waiting indicator ( stuttered dial tone and visual indicator on supported devices) DTMF in band or RFC2833 Fixed destination call immediate (hotline) 9 Baseband (non FTTH) product user guide Sept 2016

10 The Baseband IP SIP user agent (UA) manages the basic call handling capability only. Support for telephony and value add features such as Voic , Call Diversion and Call Forwarding are dependent on the platforms and services provided on your soft-switch or telephony network devices BASEBAND IP SUPPORTED ACCESS SERVICES The Baseband IP access supports the end to end delivery of analogue voice and analogue dial up services. Voice Fax. (only the G.711 transparent pass-through mode for fax (ie T.38 fax relay is not supported) Dial-up Modem (only the G.711 transparent pass-through mode for fax) Corporate Remote Access Services (RAS) Dial-up EFTPOS Monitored alarm systems, for example medical, telemetry and house burglar alarms Set-top boxes (for example, Sky Digital and My Sky) GEOGRAPHIC AVAILABILITY We ll provide a list of locations by exchange and cabinet where Baseband IP is available on you website TENURE If we intends to implement a change to the geographical coverage areas, such change will be communicated in accordance with the Operations Manual SERVICE PROVIDER HANDOVER POINT Baseband IP terminates a VPLS on your Ethernet handover connection in the exchange with the first data switch or a remote handover connection within that region. The handover connection type utilised by Baseband IP is a shared Ethernet handover connection. It can support HSNS, EUBA and Baseband IP. Details of the shared handover connection are in the Handover product user guide. The Baseband IP product utilises session boarder controllers (SBC) to manage the aggregation of the SIP traffic and the forwarding of the traffic to the appropriate handover connection based on the SIP domain contained in the SIP URI credentials recorded during the SIP registration process. We determine the number of SBCs per region. The configuration of your SIP domains(s) is unique per region and will allow for the use of the same SIP domain in each region. You can create multiple SIP domains per handover connection but cannot create multiple handover connections per domain. 10 Baseband (non FTTH) product user guide Sept 2016

11 Figure 3 Example Domain mapping to handover connections (HOC) The following table shows further examples of where you can have the same domain name in multiple regions but not one domain to multiple handover connections.

The coverage areas for Baseband IP are the same as they are for Enhanced UBA. The Baseband IP service excludes the handover connection, which is ordered separately TAIL EXTENSION You can request Baseband IP Tail Extension to have a Baseband IP service backhauled to a handover connection in another coverage area within the same region. Coverage areas are the same as specified for Enhanced UBA. The Tail Extension step A has no charge and applies where the tail is delivered to a handover connection in the same coverage area. Tail Extension steps B, C and D apply where the tail is delivered to a handover connection in a different coverage area. There are 5 regions; Northland Auckland Central North Island Lower North Island Upper South Island Lower South Island You can find further information about Baseband IP Tail Extension steps on the service provider website END CUSTOMER HANDOVER POINT 12 Baseband (non FTTH) product user guide Sept 2016

13 Baseband IP is delivered over a 2 wire copper interface to the ETP at the end customer s site. The Baseband (non FTTH) service does not include the provision and installation of CPE and wiring at the end customer s site IP ADDRESSING Baseband IP only supports IPV4 addresses and you will be responsible for end customer IP addressing TELEPHONE SERVICES You will be responsible for end customer requirements related to the telephone service that includes items such as numbering, emergency services contact, call signalling, call transportation and value added services such as call diversion, caller number display, and messaging etc SPECIFICATION Figure 3 Baseband IP architecture The key components of this solution are: Name Description ETP The demarcation point between our network and the end customer premises wiring, located at the entry to the premises or the first phone jack. 13 Baseband (non FTTH) product user guide Sept 2016

14 Baseband IP Access Node This consists of an Alcatel-Lucent 7302 ISAM with ISAM-V cards. The ISAM-V card converts analogue voice to VoIP packets using a G.711a codec with 10ms sampling. First data switch The first data switch is an Alcatel-Lucent 7450 Ethernet aggregation switch that aggregates traffic from all Baseband IP access nodes within a geographical region. The first data switch provides the earliest point at which a service provider can interconnect with the we network and consume Baseband IP Coverage area The coverage area consists of all end customers located within the geographic area served by the First Data Switch. Tail Extension Session border controller The optional tail extension service allows the Baseband IP aggregated SIP traffic to be delivered to a handover point within our regional network. The session border control acts as mediation between the we Baseband IP service and your soft-switches. Its functions include: Setting up a service provider virtual domain for handover of Baseband IP services. Aggregation of traffic and forwarding it to a service providers handover connection Forwarding service providersourced traffic to the ISAM with the registered SIP UA. Binding RSP end customers to their service provider virtual domain. Mediating SIP control messages between the RSP SIP Soft switch and the we Baseband IP Access Nodes. Handover connection The handover connection provides an Ethernet External Network-to- Network Interface (E-NNI) that allows you to interconnect with you Baseband IP services. You can access and interconnect with the handover connection by: co-locating service provider equipment at the Handover Point; connecting to third party co-location space at the Handover Point; connecting to a we or Third Party backhaul service that delivers the service to a remote location; or using the Direct Fibre Access Service to connect to service provider equipment at a remote location within the Central Office area. Baseband IP can be delivered over a shared handover connection. SIP User Agent The SIP User Agent controls and manages the SIP sessions establishment and ongoing sessions within the Baseband IP Access Node. Baseband IP uses a common SIP User Agent across multiple individual Baseband IP sessions and contains common functions such as ringing 14 Baseband (non FTTH) product user guide Sept 2016

15 cadences and dial tones. It is configured in SIP SIMPLE (TSPAN tightly coupled) mode. SBC Mediation/ Partition SIP Soft switch The session border control mediates the SIP message flows between the Baseband IP domain and your handover domains. The SIP soft switch manages the SIP traffic flows. Tightly coupled SIP mode provides you with more control over the end customer experience. Contention Baseband IP traffic is not contended within our network. However you can associate services to a handover such that the sum of all traffic profiles of services delivered at that handover exceed the handover connection 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 your responsibility to shape and queue traffic appropriately TECHNICAL SPECIFICATION Name Description User network interface 2-wire copper pair terminated at ETP.

When ordering UBA on the same copper pair as Baseband Copper or Baseband IP the service provider must be the same for both services. Where Baseband Copper or Baseband PCM is an input service to POTS then UBA and POTS can have different service providers. Your equipment must not interfere with the UBA or VDSL service (which it shares the copper path to the ETP). 16 Baseband (non FTTH) product user guide Sept 2016

Have mapping set up for each coverage area, to handover connection. Have equipment capable of supporting SIP at the handover point. 3.3 Prerequisites to placing an individual Order For transfers, perform a site audit which will provide the ASIDs for Baseband. Validate the status of each telephone number being ported out, and verify that there are no related numbers. The presence of some of these secondary or related numbers such as Faxability, Call Track, Pilot, Stepping, DDI, and Call Diversions may cause the port request to fail. Activate the voice service before the RFS date. The HDP Tie Pair for Baseband Copper is in same Zone as SLES cable pairs in the case of a Zoned exchange. 3.4 Service Order A service provider will forward an order to provisioning using Online Order and Tracking (OO&T). The order will be processed and advised as per current processes. 18 Baseband (non FTTH) product user guide Sept 2016

19 If a number port is required, timing of the separate Number Portability order must be synchronized with the order to minimize the outage for the end customer.

This forecast will show installations required at an exchange level with increased detail as the proposed installation date approaches. This detail is as follows: Monthly for forecast month 3 and subsequent months Weekly for forecast month 2 Daily for forecast month Service identifiers Baseband will have separate ASID numbers to identify each component individually for billing and reporting faults. An Access Service Identifier (ASID) is a unique 10 digit number assigned to the Baseband Copper or Baseband IP service connection at the time it is ordered BASEBAND COPPER Baseband Copper ASID numbers start with BASEBAND IP Baseband IP ASID numbers start with Bulk Ordering A number of bulk orders types will be supported as detailed. These bulk orders will process in a co-ordinated manner, a set of defined types. The coordination will involve forecasting, planning and management involving you, us and the service companies 20 Baseband (non FTTH) product user guide Sept 2016

21 working through an agreed process aligning with existing practice for Bulk Order of our services (e.g. UCLL). Bulk transfers (at a single locale) Bulk transfers involve the transfer of existing services to Baseband. Separate forecasting of a minimum number of orders for the transfer of existing services at the same exchange or cabinet (locale) must be received to initiate this process. Exception to BAU Exception to BAU orders involve the connection and/or transfer of existing or new services typically as result of a one-off market event and have the following characteristics: require separate forecasting may require increased resource are not required to be associated with a single exchange Bulk transfer for a single end customer (managed provisioning) You can use bulk transfers for single end customer orders to request additional capacity to support a customer and have the following characteristics: there are multiple lines to be transferred or connected in a coordinated manner they relate to a single end user orders are part of BAU forecasting 4.1 Current support - bulk transfers There is an interim process to accommodate bulk transfers for a defined set of transfer order types. The interim process aligns with existing practice for bulk order of our services (e.g. UCLL) but uses a different method of identifying the transfer orders and associating them with the bulk orders. 5 Faults Baseband faults can be reported to we via Online Fault Management portal (OFM) or via the B2B interface. Fault pre-diagnosis must be conducted by you to establish that the fault is not within its responsibility prior to reporting the fault to us, or determine whether to report a Baseband or broadband fault. If the pre-diagnosis indicates that the fault only impacts the Baseband IP service, the problem report has to be created using the appropriate service field value in OFM (Baseband Copper or Baseband IP). 21 Baseband (non FTTH) product user guide Sept 2016

22 If the pre-diagnosis indicates that the fault impacts both Baseband and broadband services, the problem report has to be created using the appropriate broadband service field value in OFM (Basic Unbundled Bitstream Access, Enhanced Unbundled Bitstream Access or VDSL) and choosing combined DSL and voice line for the fault is with field presented further down on that page. We will diagnose and repair any faults in our network. You re responsible for diagnosis and repair of any fault on you customer s premises and within your network. 5.1 Baseband Copper For Baseband Copper there is a charge to change the HDP tie pair if your port is faulty and another port is allocated. 5.2 Baseband IP We can offer you a range of diagnostic tests for checking and troubleshooting Baseband IP lines, with the purpose of establishing the root cause of a fault and recommending steps towards resolving a fault (e.g. rolling a truck). The tests are integrated in the Service Performance Manager (SPM) portal and available for selection under the Baseband IP test category. Note that the tests under the PSTN category will not work for Baseband IP lines. A software module of the 5530 network analyser, called narrowband line testing (NBLT) is the enabler of these line diagnostic tests. For Baseband IP s Tail Extension, faults will either be logged against the Baseband IP access service or the associated Handover Link. 6 Service levels Service level Attribute Service Level Level 1 Order acknowledgement Provide acknowledgment of receipt of each Order to the Access Seeker within 4 Consecutive Business Hours following the Receipt Time 22 Baseband (non FTTH) product user guide Sept 2016
