Local-loop unbundling

Local-loop unbundling

Local loop unbundling (LLU) is the regulatory process of allowing multiple telecommunications operators use of connections from the telephone exchange's central office to the customer's premises. The physical wire connection between customer and company is known as a "local loop," and it is owned by the incumbent local exchange carrier, (also referred to as the "ILEC," "local exchange," or in the United States either a "Baby Bell" or an Independent telephone company).

Policy background

LLU is generally opposed by the ILECs, which in most cases are either former investor-owned (North America) or state-owned monopoly enterprises forced to open themselves to competition. ILECs argue that LLU amounts to a regulatory taking, that they are forced to provide competitors with essential business inputs, that LLU stifles infrastructure-based competition and technical innovation because new entrants prefer to 'parasitise' the incumbent's network instead of building their own and that the regulatory interference required to make LLU work (e.g., to set the LLU access price) is detrimental to the market.

New entrants, on the other hand, argue that since they cannot economically duplicate the incumbent's local loop, they cannot actually provide certain services, such as ADSL without LLU, thus allowing the incumbent to monopolise the respective potentially competitive market(s) and stifle innovation. They point out that alternative access technologies, such as Wireless local loop (WLL) have proven uncompetitive and/or impractical, and that under current pricing models, the incumbent is (in many cases depending on the regulatory model) guaranteed a fair price for the use of his facilities, including an appropriate return on investment. Finally, they argue that the ILECs generally did not construct their local loop in a competitive, risky, market environment, but under legal monopoly protection and using ratepayers (or possibly taxpayer's) money, which means - according to the new entrants - that ILECs ought not to be entitled to continue to extract regulated rates of return which may include monopoloy rents from the local loop.

Most developed nations, including the USA, Australia and the European Union Member States, have introduced regulatory frameworks providing for LLU. Given the above-mentioned problems, regulators face the challenging task of regulating a market that is changing very rapidly, without stifling any type of innovation, and without improperly disadvantaging any competitor.

The process has been long - the first action in the EU resulted from a report written for the European Commission in 1993. It took several years for the EU legislation to require unbundling and then in individual EU countries the process took further time to mature to become practical and economic rather than simply being a legal possibility.

The 1993 report referred to the logical requirement to unbundle optical fibre access but recommended deferral to a later date when fibre access had become more common. In 2006 there were the first signs that (as a result of the municipal fibre networks movement and example such as Sweden where unbundled local loop fibre is commercially available from both the incumbent and competitors) policy may yet evolve in this direction.

Unbundling developments around the world


Some provisions of WTO telecommunications law can be read to require unbundling:
* Sect. 5(a) of the GATS Annex on Telecommunications [ [http://www.wto.org/english/docs_e/legal_e/26-gats_02_e.htm#articleXXIX WTO | legal texts - Marrakesh Agreement ] ] requires WTO Members to guarantee service suppliers "access to and use of public telecommunications transport networks ... for the supply of a service". New entrants argue that without LLU they cannot supply services such as ADSL.
* Sect. 2.2(b) of the 1998 Reference Paper, [ [http://www.wto.org/english/tratop_e/serv_e/telecom_e/tel23_e.htm WTO | Services: Telecommunications - Negotiating Group on Basic Telecommunications 24 April 1996 ] ] to which some Members have subscribed, requires "sufficiently unbundled interconnection" with major providers. However, the Paper's definition of interconnection appears to exclude LLU.
* Sect. 1 of the Reference Paper requires Members to maintain "appropriate measures ... for the purpose of preventing [major] suppliers ... from engaging in or continuing anti-competitive practices." New entrants argue that such practices include not giving competitors access to facilities essential to market entry, such as the local loop.

The question has not been settled before a WTO judicial body, and, at any rate, these obligations only apply where the respective WTO Member has committed itself to open its basic telecommunications market to competition. About 80 (mostly developed) Members have done so since 1998.


The implementation of Local Loop Unbundling is a requirement of European Union policy on competition in the telecommunications sector and has been introduced, at various stages of development, in all member states (Operators with Significant Market Power shall publish (from 31 December 2000, and keep updated) a postreference offer for unbundled access to their local loops and related facilities. The offer shall be sufficiently unbundled so that the beneficiary does not have to pay for network elements or facilities which are not necessary for the supply of its services, and shall contain a description of the components of the offer, associated terms and conditions, including charges).

European States that have been approved for membership to the EU have an obligation to introduce LLU as part of the liberalisation of their communications sector.


As of 14 January 2006, 210,000 local loop connections had been unbundled from BT operation under local loop unbundling. Ofcom had hoped that 1 million local loop connections would be unbundled by June 2006. However, as reported by [http://www.theregister.co.uk/2006/06/15/llu_openreach/ The Register] , on 15 June 2006, the figure had reached only 500,000, but was growing by 20,000 a week. Ofcom announced in November 2006 that 1,000,000 connections had been unbundled. [ [http://www.offta.org.uk/updates/otaupdate20061107.htm News | Office of the Telecoms Adjudicator ] ] By April 2007, the figure was 2,000,000.

Most LLU operators only unbundle the broadband service leaving the traditional telephone service using BT's core equipment (with or without the provision of Carrier preselect). Where the traditional telephone service is also unbundled (full LLU), operators usually prohibit the facility where selected calls can be made using the networks of other telephone providers (i.e. accessed using a 4 or 5 digit prefix beginning with '1'). These calls can usually still be made by using a 0800 or other non-geographic (NGN) access code.


Pursuant to the Telecommunications Act of 1996, the Federal Communications Commission (FCC) requires that ILECs lease local loops to competitors. Prices are set through a market mechanism whose effectiveness is not yet clear.

New Zealand

The Commerce Commission recommended against local loop unbundling in late 2003 as Telecom offered a market-led solution. In May 2004 this was confirmed by the Government, despite the intense [http://www.call4change.co.nz "call4change"] campaign by some of Telecom's competitors. Part of Telecom's commitment to the Commerce Commission to avoid unbundling was a promise to deliver 250,000 new residential broadband connections by the end of 2005, one-third of which were to be wholesaled through other providers. Telecom failed to achieve the number of wholesale connections required, despite an attempt by management to claim that the agreement had been for only one-third of the growth rather than one-third of the total. [ [http://www.comcom.govt.nz/IndustryRegulation/Telecommunications/BroadbandMonitoring/correspondence.aspx] Dead link|date=July 2008] That claim was rejected by the Commerce Commission, and the publicised figure of 83,333 wholesale connections out of 250,000 was held to be the true target. The achieved number was less than 50,000 wholesale connections, despite total connections exceeding 300,000.

On the 3rd of May 2006 the New Zealand Government announced it would require the unbundling of the local loop. This was in response to concerns about the low levels of broadband uptake. Regulatory action such as information disclosure, accounting separation of Telecom New Zealand business operations, and enhanced Commerce Commission monitoring was also announced.

On Thursday 9 August 2007, Telecom released the keys to two exchanges - in Glenfield and Ponsonby. Ihug announced that they will be releasing 24 megabits per second broadband for $29.95 in these areas.

In March 2008, Orcon activated ADSL 2+ services from five Auckland-based exchanges - Glenfield, Browns Bay, Ellerslie, Mt Albert and Ponsonby - with further plans for the rest of Auckland and other major centres.


Switzerland is one of the last OECD nations to provide for unbundling, because the Swiss Federal Supreme Court held in 2001 that the 1996 Swiss Telecommunications Act did not require it. The government then enacted an ordinance providing for unbundling in 2003, and Parliament amended the act in 2006. While infrastructure-based access is now generally available, unbundled fast bitstream access is limited to a period of four years after the entry into force of the act.

Unbundling requests tend to be tied up before the courts, however, because unlike in the EU, Swiss law does not provide for an "ex ante" regulation of access conditions by the regulator. Instead, under the Swiss "ex post" regulation system, each new entrant must first try to reach an individual agreement with Swisscom, the state-owned ILEC.

Hong Kong

Mandatory local loop unbundling policy (termed Type II Interconnection (Traditional Chinese:第二類互連) in Hong Kong) started in 1995 (the year of telephone market liberalisation), to ensure choice to customers. After 10 years, new operators have built their networks covering a large region of Hong Kong; the government considered it a good time to withdraw mandatory local loop unbundling policy, to persuade operators to build their own networks and let businesses run themselves with a minimum of government intervention.At the meeting of the Executive Council on 6 July 2004, the Council advised, and the Chief Executive ordered, that the regulatory intervention under the current Type II interconnection policy applicable to telephone exchanges for individual buildings covered by such exchanges should be withdrawn, subject to conditions documented in [http://www.ofta.gov.hk/tas/interconnect/ta20040706.pdf this Statement of the Telecommunications Authority] . After that, the terms of interconnection will be negotiated between telephone operators. Hong Kong is the first and the only advanced economy that has withdrawn the mandatory local loop unbundling policy.

outh Africa

On 25 May 2006 the Minister of Communications of South Africa Dr Ivy Matsepe-Casaburri established the Local Loop Unbundling Committee chaired by Professor Tshilidzi Marwala to recommend the appropriate local loop unbundling models. The Local Loop Unbundling Committee submitted a report to Minister Matsepe-Casaburri on 25 May 2007. This report recommends that models that permit customers to access both voice and data be offered by many different companies. The models recommended are Full Unbundling, Line Sharing and Bitstream Access. It is recommended that customers should exercise carrier pre-selection and thus be able to switch between service providers. It is also recommended that an organisation be created to manage the local loop and that this organisation should be under the guidance of the regulator Icasa and that Icasa be capacitated in terms of resources. The committee recommended that service providers approved by Icasa should have access to the telephone exchange infrastructure whenever necessary. The committee recommended that a regulatory guideline be established and be managed by Icasa to guarantee that strategic issues like quality of the local loop be optimised for regulation and delivery of services. Based on this report the Minister has issued policy directives to Icasa to move swiftly with the unbundling process.
