Broadband, the Local Loop and New Operators Doc Ref 00712/PN/774.1
Unbundling – the herald of competition • Unbundling is …. • Politically popular; • An admission that previous policies have not really worked; • New route to market for broadband services; • Probably potentially profitable for some • Unbundling is not…. • A way of providing USO wide band services; • An easy option Doc Ref 00712/PN/774.1
ULL – the standard picture • The Characteristics of Local Loop Unbundling are: • It is an access service between the Network Terminating Point (NTP) and the Main Distribution Frame (MDF); • It is open to providers other than the Incumbent, so removes a bottleneck to competition • And it can take various forms • Copper pair rented by new operator for its exclusive use to provide full services including DSL (Full Unbundling) • Incumbent continues to provide POTS & the new operator provides high speed services. The local loop remains part of the public switched network (Shared Access) • Incumbent installs DSL to the customer and sells wholesale to the new entrant. There is no unbundling involved! (Bitstream) Doc Ref 00712/PN/774.1
ULL – the full story • Simple DSL resale – a new entrant resells an undifferentiated DSL access service in conjunction with its own portfolio of value added services • Wholesale DSL or bitstream access - a new entrant delivers its own access services that incorporate DSL elements provided by the incumbent • Unbundled local loop – a new entrant uses the ‘metallic path’ between the incumbent’s local exchange and an end user’s premises as a constituent part of its own services • Line sharing – a new entrant uses the portion radio spectrum on the ‘metallic path’ that is not used for PSTN or ISDN services as an element in its services; the PSTN or ISDN portion remain in the control of the incumbent and may be used by the incumbent to provide other services • Sub loop unbunding – a new entrant uses the ‘metallic path’ over a segment of the local loop from the end user’s premises, to an intermediate point in the local loop as a constituent part of its own services. • Duct sharing – a new entrant places its own infrastructure in the ducts or on the poles of the incumbent • Trench sharing – a number of operators collaborate to dig a combined trench and each then lays its own ducts and cables.

Relationship between alternative forms of access and ancillary services Doc Ref 00712/PN/774.1
Collocation Site Boundary Other Licenced Operator’s POP (Switch Location) Incumbent Operator’s POP (Telephone Exchange) OLO Cable Chamber OLO infrastructure • Advantages • Own local POP not required • Ability to address Local Loop access at a later stage • Disadvantages • Cost, access, security • Installation and Maintenance • Requires OLO Infrastructure Doc Ref 00712/PN/774.1
Sharing physical infrastructure • Advantages • Reduced environmental impact • Reduced traffic disruption when an OLO builds out a new network • Reduced overall investment requirement by a new entrant to a market • Improved return to the incumbent on an investment in infrastructure. • Disadvantages • Network integrity • Availability of spare capacity Doc Ref 00712/PN/774.1
Collocation • Collocation space may be provided: • In a distinct caged space accessible to an OLO with or without separate entrance facilities. The OLO can request space to locate its equipment within the incumbent operator’s local Main Distribution Frame (MDF) site or equivalent distribution point closer to the user premises, either in the building containing the MDF or in other space that could be made available in the site (such as adjacent buildings, car parks or warehouses). • In a separate uncaged space. This space can be fitted and operated in an area within a incumbent operator’s exchange where the incumbent operator houses its own equipment, • Within a single overall space shared with the incumbent; this form of collocation is often referred to as co-mingling • As virtual collocation space, where the equipment is managed in its entirety by the incumbent on behalf of the OLO. • At a distant or adjacent collocation – an OLO can choose to use its own premises and connect to the incumbent operator’s local MDF site or equivalent distribution point closer to the user premises. Doc Ref 00712/PN/774.1
Collocation and Facility Sharing • The regulator should encourage sharing of facilities and/or property • Agreements are normally commercial and technical between the parties • The regulator would usually intervene in case of dispute • After public consultation a regulator may impose facility or property sharing Doc Ref 00712/PN/774.1
Collocation Services • Hand-over Distribution Frame (HDF) , including the street cabinet where this is relevant to sub loops • Tie Cables • Internal Tie Cable • External Tie Cable • OLO’s External Tie Cable Pull-Through Service • Transmission and backhaul Services • Power • Air conditioning/chilling/heating (as relevant) • Access to collocation space • Equipment moving assistance (where lifting/hosting apparatus is needed) Doc Ref 00712/PN/774.1
The wider scope of sharing • Masts • Allows second operator to rollout network faster • Requires rules for access, safety, loading etc • Widely mandated (e.g. Bahrain) • Ducts • Often not feasible or prohibitively expensive to install new ducts • Widely mandated (e.g. Singapore) • Affects rollout speed of both national and local network • Exchange space • Essential for access to unbundled local loop • Usually implies significant overhead (e.g. access controls to preserve security) Doc Ref 00712/PN/774.1

ULL and Interconnect Doc Ref 00712/PN/774.1
A Review of Interconnect • In the early days of telecommunication liberalisation, interconnect meant just ‘interconnection” • Definitions: • The commercial and technical arrangements under which service providers can connect their equipment, network and services to enable customers to have access to the customers, services and networks of other service providers. ITU • linking with suppliers providing public telecommunications transport networks or services in order to allow the users of one supplier to communicate with users of another supplier and to access services provided by another supplier, wherespecific commitments are undertaken WTO • “interconnection” means the physical and logical linking of public communications networks used by the same or a different undertaking in order to allow the users of one undertaking to communicate with users of the same or another undertaking, or to access services provided by another undertaking. Services may be provided by the parties involved or other parties who have access to the network. Interconnection is a specific type of access implemented between public network operators; EU Directive 2002/19/EC • Key points - Interconnection • is essential for telephony services • is specific to public network operators • is a specific type of access Doc Ref 00712/PN/774.1
Access • As competition has evolved so it has become desirable to broaden the scope of interaction between dominant and other operators and the concept of ‘Access’ has arisen • “access” means the making available of facilities and/or services, to another undertaking, under defined conditions, on either an exclusive or non-exclusive basis, for the purpose of providing electronic communications services. • It covers inter alia: • access to network elements and associated facilities, which may involve the connection of equipment, by fixed or non-fixed means (in particular this includes access to the local loop and to facilities and services necessary to provide services over the local loop), • access to physical infrastructure including buildings, ducts and masts; • access to relevant software systems including operational support systems, • access to number translation or systems offering equivalent functionality, • access to fixed and mobile networks, in particular for roaming, • access to virtual network services; EU Directive 2002/19/EC Doc Ref 00712/PN/774.1
Wholesale • Another specific form of access now frequently included under the umbrella of ‘Interconnect’ is access to standard, retail services at a ’wholesale’ price. • Customisation of these services may sometimes be offered – eg multiple leased line services could be offered in an aggregate format • The offering of ‘wholesale’ prices to operators is often viewed as a purely commercial transaction, in principle no different to that between an operator and any other non-operator major user of his services. • However, in certain areas the regulator may deem such services to be necessary to support the development of competition and may influence or determine the terms on which they are offered. Doc Ref 00712/PN/774.1
RIO or RAO? • The RIO should contain at least all interconnect services (i.e. those required to deliver traffic that originates on one network to another) • The RIO may be limited to the services required for the termination of traffic • In this instance, a separate agreement would be needed to cover Wholesale and Access services – the Reference Access Offer (RAO) • Is there a preferred approach? • A combined or consolidated RIO gives a single point of reference • RIO plus RAO distinguishes different types of service • One RIO ensure a uniform approach to provisioning etc • RIO plus RAO admits flexibility (e.g. in the timing of the offers) Doc Ref 00712/PN/774.1

Content of the RAO • Format is similar to that for a RIO – physical interconnect and PoIs, interconnect services, costs and terms. • Content depends on the precise definition of “Access” • This may be limited to the local loop, may extend to wholesale service and could include: • Resale of specified services to licensed network operators or service providers; • Collocation or other forms of facility sharing (e.g. ducts, buildings, masts); • Access to specified network elements or facilities, including, but not limited to Unbundled Local Metallic Path and Line sharing; • Access to technical interfaces, protocols or other key technologies that facilitate the interoperability of services that relate to the relevant market; • Access to specified services needed to ensure interoperability between users, of end-to-end services (end to end services are those network services provided to customers other than network operators as part of a retail service) relating to that market; • Access to operational support systems or similar software systems that are needed to enable fair competition in the provision of services relating to that market. • Finally, the RAO may be available to a wider range of operators than the RIO Doc Ref 00712/PN/774.1
Carrier Pre-Selection Doc Ref 00712/PN/774.1
Carrier Pre-Selection Without CPS: LX TX LX With CPS: LX TX LX IX • Pre-selected Operator bills the customer PSOSwitch Doc Ref 00712/PN/774.1
Scope of Pre-selection • Single basket or Multi Basket • Different carriers for different call types (e.g. consumer can select one carrier for National calls, another for International) or one pre-selected carrier for all? • Call by call over-ride • Short code allowing reversion to incumbent? • Operators who have to provide pre-selection • Dominant, Significant Market Power? • Operators eligible for pre-selection • Criteria, such as conformance to safety, security standards, technical soundness etc? • Fixed, Mobile, National, International • Exclusions usually include calls from public payphone lines, special and premium rate services etc Doc Ref 00712/PN/774.1
CPS Issues • Slamming • Unauthorised changes to a consumers carrier selection preferences • Formal change control process • Costs • CPS involves the installation of extra equipment and resources (e.g. billing, switch data changes, customer records). These need to be taken into account in the costing of call transfer • Market competition • Customer information (e.g. for price comparison) • Impact on other services (for example, CPS can diminish the advantage of VoIP services when origination charges are closely aligned with costs (i.e. very low). In this instance the IP based operator has little cost advantage over a conventional competitor, but has added inconvenience (e.g. distributing a VoB converter) • Numbers available for Interconnect Doc Ref 00712/PN/774.1

Regulators role • Most regulators ensure: • availability of carrier pre-selection • each operator has a number plan for their allocated ranges • that number changes are properly managed, advertised and supported • that a clear process for choosing a pre-selected carrier is in place • that a clear change control process between operators is in place • that costs are appropriately apportioned between operators • that consumer issues are demonstrably attended to (e.g. anti-slamming measure, consumer forum for CPS etc) Doc Ref 00712/PN/774.1
Number Portability Doc Ref 00712/PN/774.1
Number Portability • Number Portability is a facility that enables a customer to change network operator and/or service provider while retaining their E.164 number • In the process of changing network operator and/or service provider the customer may lose supplementary services related to the basic service • Requires additional capabilities in the network to properly route the call to the final destination. The two options for implementing number portability are; • Intelligent Network (IN) based solutions, which is the more flexible but expensive option (both cost and load on switches) • Signalling Relay Function (SRF) based solutions, which are simpler and cheaper to implement but not flexible Doc Ref 00712/PN/774.1
Issues in Number Portability • Using Number Portability between fixed and mobile networks would dissolve the geographic numbering plan as geographic numbers will be used for phone calls to mobile phones and mobile numbers for phone calls to fixed lines. • Geographic information in a phone number will be lost, as well as the ability of a differentiated tariff between fixed and mobile, due to the need for harmonised tariffs for these calls. • Different tariffs to fixed and mobile lines may confuse users. Considering those problems, users’ interest for fixed-mobile portability has to be proved before considering its possible introduction. • If a call is originated in the fixed network and the called party is in the mobile network but ported to the fixed network, would a release lead to a database query in the fixed network or in the mobile network? • If the called party is in the mobile network and ported to another mobile network, does the release lead to database query in the mobile network? • Or would it be better to get a routing information from the fixed network? • The situation is further complicated by the emergence of converged networks which open the possibility of using personal identifiers that may be dynamically associated with a network address • All possible scenarios must be investigated concerning their regulatory implications. Doc Ref 00712/PN/774.1
Regulators Role • to evaluate the pros and cons of number portability, with special attention to the emergence of converged networks • to ensure that customer interests are taken into account concerning: • whether customer procedures are simple to follow and how well customers are informed • for what reasons and for how long the porting process can be blocked • which and how many numbers a customer can port per changeover • how limited time scales are for the preparation of the porting • how limited disruption is during the actual changeover. • to administer the porting of E.164 numbers (centralised or decentralised databases) Doc Ref 00712/PN/774.1
Summary • We have addressed a number of issues related to consumer access • ULL, which enables competition among operators in the access network • Carrier pre-selection, which gives consumers choice in which operator they use • Number Portability, which removes a barrier to consumers moving between operators • Each of these promotes interaction between carriers • Each has some bearing on Interconnect Doc Ref 00712/PN/774.1
