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.


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


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.

2.2.1 GEOGRAPHIC AVAILABILITY


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.

2.2.2 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 non-

availability, 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.

2.2.3 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.

2.2.4 END CUSTOMER HANDOVER POINT

The Baseband Copper service is delivered to the ETP at the end customer’s building.

http://www.sp.chorus.co.nz/


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 www.telepermit.co.nz) and the

Code of Practice for Residential and Small Office Premises Wiring (available at

www.tcf.org.nz/premwiring) are adhered to.

2.2.5 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.

2.2.6 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


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.

2.3.1 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 183

043)

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)



The Baseband IP SIP user agent (UA) manages the basic call handling capability only.

Support for telephony and value add features such as Voicemail, Call Diversion and Call

Forwarding are dependent on the platforms and services provided on your soft-switch or

telephony network devices.

2.3.2 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)

2.3.3 GEOGRAPHIC AVAILABILITY

We’ll provide a list of locations by exchange and cabinet where Baseband IP is available

on you website.

2.3.4 TENURE

If we intends to implement a change to the geographical coverage areas, such change

will be communicated in accordance with the Operations Manual.

2.3.5 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.


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.

A coverage area is the collection of DSLAMs in a geographic area connected to a

Handover Point. 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.

2.3.6 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.

2.3.7 END CUSTOMER HANDOVER POINT




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.

2.3.8 IP ADDRESSING

Baseband IP only supports IPV4 addresses and you will be responsible for end customer

IP addressing.

2.3.9 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.

2.3.10 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.


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 The optional tail extension service allows the Baseband IP aggregated SIP traffic to be delivered to a handover point within our regional network.

Session border controller

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


cadences and dial tones. It is configured in SIP SIMPLE (TSPAN tightly coupled) mode.

SBC Mediation/ Partition

The session border control mediates the SIP message flows between the Baseband IP domain and your handover domains.

SIP Soft switch 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.

2.4 Baseband with broadband

Baseband may be provided in conjunction with the following broadband variants by the

same service provider on the same copper pair to the end customer;

Basic UBA FS/FS

Basic UBA 256/128

Enhanced UBA 0kbps

Enhanced UBA 40kbps

Enhanced UBA 90kbps

When Baseband is provided in conjunction with Broadband the description of UBA will

show which type of Baseband, for example EUBA 0 with Baseband Copper or EUBA 0

with Baseband IP.

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).

3.2 Prerequisites

3.2.1 BASEBAND COPPER

Before you order Baseband Copper you must have unbundled the local exchange and

installed your equipment (or agreement to another service provider), in the local

exchange where Baseband Copper terminates.

3.2.2 BASEBAND IP

The following prerequisites must be in place before your first order for Baseband IP;

Have a shared handover connection in each region that you wish to serve.

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.


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.

Request types include:

New Connection of Baseband with or without Out Porting

Transfer of Baseband between service providers

Transition from SLU and SLES to Baseband with or without Out Porting

Move address Baseband

Relinquishment of Baseband (leaving UBA or VDSL without POTS)

Change HDP Tie Pair (Baseband Copper only)

UBA/VDSL Request types include:

New Connection of Baseband and UBA or VDSL

Relinquishment of UBA or VDSL (leaving Baseband)

Transition to or from UBA or VDSL with Baseband with or without Out Porting

3.6 Forecasting



Baseband Copper is forecast monthly for 12 months, by exchange cluster on our

forecasting form and sent to [email protected].

3.6.2 BASEBAND IP

Baseband IP is forecast monthly for 12 months, by exchange cluster on our forecasting

form and sent to [email protected].

3.7 Bulk forecasting

For Bulk Orders you’ll provide us with an accurate forecast of monthly numbers, 3

months in advance. 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 1

3.8 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 ASID numbers start with 1625.

3.8.2 BASEBAND IP

Baseband IP ASID numbers start with 1617.

4 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

mailto:[email protected]

mailto:[email protected]


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).


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.
