3.5 Key interconnect issues in APEC member economies
Transparency of interconnection arrangements
Unbundling of service elements and local service competition
Resale and market structure
However, common to all economies are:
The more effective the interconnection regime in an individual economy in promoting the development of competition, the more likely the collective objective for the APEC region will be realised.
In this context, we believe that the key interconnection issues for APEC are:
Each of these issues is dealt with below.
-- Transparency of interconnection arrangements
-- Residual market power of incumbents and competitive safeguards
-- Unbundling of service elements and local service competition
Role of the regulator and of regulation
The need for regulatory agencies which are independent of telecommunications operators is well recognised within APEC member economies. Independence of regulatory (implementation) activity from government (policy) activity is not as well recognised in current arrangements. The power and authority of regulators to intervene, the circumstances under which they may do so, and the level of discretion afforded by legislation, are critical matters in the interconnection policy framework.
To date, throughout the APEC economies, there have been limited opportunities for regulators to become involved in resolving inter-carrier disputes or failures associated with the negotiation of interconnection agreements. Interconnection regimes are commonly of such recency in many jurisdictions that opportunities have not yet fully arisen that require regulatory agency intervention.
A key issue is whether the development of interconnection regimes, and the achievement of the consequential benefits for enhanced competition, will be hastened or retarded by the absence of regulatory involvement. In some jurisdictions, notably New Zealand and Australia, there is heavy emphasis on self-regulation and the bilateral commercial negotiation of operators. Industry self-regulation comes in many forms. In all forms it is largely untested. It remains to be seen whether operators in the marketplace, and incumbent carriers in particular, have a greater interest in fully testing the boundaries of interconnection legislation through regulatory and court systems, than in negotiating direct outcomes with each other and with new entrants in a timely manner.
It cannot be stressed too much that the transparency of an interconnection regime and the accuracy of the descriptions of its key requirements are paramount in permitting the introduction of early and effective competition. Functional characteristics of interconnecting services need to be carefully specified to ensure that an end user is not inhibited in any way when establishing a connection between parties via two or more networks. Another case is the publication of clear and comprehensive guidelines concerning the powers of a regulator and the circumstances and processes that relate to its intervention. Participants need to be able to assess the value of regulatory involvement and to assess the risks to them of various courses of behaviour.
Most member economies rely on commercial negotiation between the parties to achieve interconnection agreements. The arrangements arrived at between the parties, in particular the charges, are then treated as commercially confidential information of the parties.
The lack of public information of interconnection charges may lead to undesirable results such as a lack of benchmarks for other entrants when dealing with incumbents, possible strengthening of the incumbents' position in negotiation, and additional delay in negotiating agreements.
A key issue is whether the objectives of regulatory and market reform in this area might not be better advanced by publishing key terms of interconnect agreements, at the possible expense of traditional commercial privacy values.
A critical issue is the ability of both regulators and operators to obtain expeditiously relevant cost and other information especially from the incumbent. Historically information, particularly cost information, is not normally kept in a form which lends itself to analysis for the purposes of interconnect charge determination. As well, incumbent carriers have little incentive to make such information as does exist available to regulators or potential competitors. Well meaning efforts to discern true costs can easily degenerate into lengthy, costly, insoluble, and ultimately irrelevant academic debates delaying the introduction of effective interconnection. In order to avoid this, the regulator should decide on its policy goals, choose a costing policy that is consistent with those goals, and proceed on that basis.
Residual market power of incumbents and competitive safeguards
In most APEC member economies the incumbent carriers have considerable market power which is not only reflected in market share, but also in terms of their access to resources, substantial skill sets, relationships with suppliers, and control of critical information and knowledge. In some economies the incumbent retains functions that might be better placed with the regulatory agencies.
The risk that an incumbent may delay or otherwise inappropriately influence negotiations needs to be firmly addressed in the interconnection framework. As competition increases, the continuing relevance and application of the safeguards will need to be examined.
As a minimum, the framework should address the following issues:
There are essentially two ways of arriving at interconnection arrangements between operators: they can be set by the regulator or they can be commercially agreed between the operators (with or without some degree of regulatory agency involvement). Hybrid arrangements are also possible and in evidence.
The preference exhibited in most interconnect frameworks among APEC member economies is for commercial negotiation between the operators. There are advantages in this approach, including:
However, there are disadvantages, including:
To minimise the delays and risks inherent in commercial negotiations, some degree of regulatory involvement in the process is usually contemplated, such as:
The interconnection frameworks of the member nations adopt varying degrees of regulatory intervention in commercial negotiation. On the one hand, for example, the model proposed for Singapore contains probably the most detailed and comprehensive provisions for the conduct of negotiations, with regulatory oversight and involvement. On the other hand, New Zealand's framework relies solely on commercial negotiation with ultimate recourse to the judicial system under the general competition law.
The basis on which regulators might intervene is also an important issue. If regulators are to arbitrate, the issue is whether they may apply wide discretion in the context of their agency charters, or whether they are constrained to determine charges and other terms of interconnection in terms of guidelines established by legislation or, in advance, by the agencies themselves. In most APEC member economies there is a clear preference that cost should form the basis for regulatory interconnection charging determinations, and a further preference for incremental costs to be applied, rather than the fully allocated costs of the operator providing access. The experience of most member economies in applying cost considerations to interconnect issues is very limited to date.
The guidelines within which regulators operate, and the precedents that they develop over time, through their various arbitrations and other determinations on the subject of interconnection, will invariably influence the basis on which inter-party commercial negotiations are conducted.
Many APEC economies agree that one of their priorities is to improve service for users, the majority of whom are affected most by the availability and price of local service. Unbundling service elements is an approach to maximise competition in local service and, thereby, bring the benefits of competition ? better and cheaper service ? to the majority of telecommunications users. Unbundling of services can also benefit the incumbent carrier by increasing utilisation of the existing network. For example, in the U.S. and Japan, where local service competition has become a priority after many years of competition in other service areas, unbundling local service elements has been adopted as the preferred approach.
If an economy adopts an unbundled service elements approach, the issues for pricing these elements are similar to those already discussed in relation to the basis for establishing interconnection charges. To briefly recapitulate:
Resale can be used to encourage competition in terms of price and customer service. Resale allows for earlier entry and operation in the market, and can avoid uneconomic investment. New entrants who start as resellers can build a customer base which may grow to enable them to generate the scale necessary to support investments in their own facilities at a later date. In the U.S., for example, the second largest facilities-based carrier, MCI, began as a reseller competing against AT&T.
Significant issues in establishing a framework for resale include:
To date, mobile interconnection terms have been constructed in a different manner to fixed interconnection. There has typically been no relation to network costs. A key issue, as mobile becomes a lower priced, mass market service, will be the merging of interconnection regimes between fixed and mobile services.
Inclusion of universal service contributions, and perhaps also access deficit contributions, in interconnection charges raises issues such as:
Competitive services | Utility services | |
Type of services | Long distance data and broadband services | Telephony services |
Earnings regulation | No |
Rate of return regulation until January 1998 Price caps from 1998 |
CRTC interest in profitability of telco | No | Not after 1998 |
Carriage of investment risks | Shareholders | Customers (for services where sufficient competition has not emerged) |
Investment in broadband capacity | In general, broadband capacity is allocated to this segment and transfer priced if required by utility segment | Can only be included if there is a demonstrated requirement for the bandwidth |
Role of the regulator
To date the CRTC has ordered interconnection to provide competitive long distance and local telecommunications, and wireless services.
The specific interconnection regime developed by the CRTC is seen as being effective in the promotion of competition, because:
(19Y it is open to all competitors
(19Y it has developed common terms and conditions of interconnection and entry obligations
(19Y it includes a competitively neutral universal service contribution regime (see below).
Outline regulation of interconnect
*p1291 the implementation of a Carrier Access Tariff (CAT) to provide for the recovery by the utility segment from the competitive segment and from competitors of charges for contribution, bottleneck services and start-up costs
*p1291 the price imputation test which ensures the telephone companies' rates are not anti-competitive
*p1291 staged pre-set local rate increases to be offset by reductions in basic toll rates
*p1291 the move to price cap regulation in 1998 of the Utility segment after a transitional period
*p1291 the direction to the telephone companies to file tariffs for co-location and the unbundling of bottleneck services to allow for local competition.
Interconnection obligations
For the purposes of local wireline (fixed) service, competitors must interconnect with the PSTN, and must interconnect with each other. Local exchange carriers must allow all alternative providers of long distance services to interconnect with their networks. The obligation is placed on all carriers and service providers entering the local telecommunications market, and is enforced by the CRTC, either at its own request or at the request of an interested party. The CRTC has a range of enforcement instruments at its disposal under the Telecommunications Act.
Interconnection rights extend to all telecommunications services, and this includes data as well as voice communications.
Interconnect charges
The interconnect regulatory framework requires charges to be set on the basis of costs ? being long run incremental costs plus a mark up for common costs. This cost basis has been in place for a considerable time.
Unbundled local loop
Number portability
How the costs of number portability will be apportioned has not yet been determined. It is likely that it may be on a charge per transaction basis.
An independent third party chosen by the service providers will administer the numbering data base. The costs will be spread over the entire rate base, and will have little effect on the competitiveness of new entrants.
Universal service obligation
Rate regulation and a complex system of cross-subsidies from long distance, business and other premium services revenues are the traditional means used to maintain low cost basic residential service. In principle, all long distance operators have to contribute to USOs for long distance traffic carried on the local networks. These contribution revenues will be disbursed to local exchange operators based on their subsidy requirement (based, in turn, on the operator's costs)
Contributions are based on a per minute charge referable to interexchange traffic volume carried by long distance service providers.
USO contributions are not factored into interconnect charges.

basic services. These include telephony, leased lines and telex. For these services the Government has granted exclusive licences to two 100% government owned companies - PT Telkom for national basic services and PT Indosat for international basic services. Exclusivity runs out in 2005 (Indosat) and 2006 (Telkom)
non basic services. These include value added services. The market for providing these services is open.
Because of the exclusivity arrangements any new entrant must reach a co-operative arrangement with one of the two incumbents. This co-operation normally takes one of two forms:
a joint venture in which the new entrant(s) and Indosat or Telkom create a new company which operates as a separate entity
a joint operation scheme in which a new entrant invests jointly with Indosat or Telkom in a unit which is jointly operated.
In either case foreign participation is limited to 35%.
As well as encouraging joint co-operation schemes the Government has also partly privatised both incumbents - floating 35% of Indosat and 25% of Telkom on the Indonesian and New York stock exchanges.
Under each KSO, private investors, normally one local company and one foreign telephone company, make an up front investment to build out the local network and operate it jointly with Telkom. To compensate Telkom for the financial benefits that it would have received from its existing installation in the region if a KSO had not been entered into, the KSO private investors are required to pay Telkom the Minimum Telkom Revenue, which is an agreed monthly payment for the term of the KSO. In return the private investors receive a share of the additional revenues generated for the fifteen year period from the beginning of 1996. The share covers the investor's operating costs and provides a reasonable return on the investment. The KSO private investors keep all revenue from all national calls and also receives revenue from interconnect charges.
At the end of the 15 year period, all of the lines constructed by the KSO investors are to be transferred to Telkom for a nominal payment. However, under the KSO Agreements, at any time after 31 December, 2005- which is 10m years after the start of the KSO ? Telkom has an option to purchase the new installation. Telkom can pay a purchase price based on the projected value of revenues that would have been generated in the remaining KSO period by the new facilities installed by the KSO.
International fixed services are run under a duopoly between the incumbent Indosat and the new entrant Satelindo.
MTPT's main functions are:
Retail price control(19Y
retail price control (19Y

spectrum allocation.
Telkom can set its line rental, local and long distance prices within the price cap. This gives it freedom to rebalance. However the Minister retains the right to reject price changes proposed, even if they comply with the price cap regime. Telkom made some modest price rebalancing moves at the beginning of 1997.
MTPT still sets international and mobile prices, after consulting the operators.
4.7.4Interconnect arrangements
MTPT determines most of the interconnect arrangements without the operators negotiating, using a similar process to that used for retail price control as discussed in the previous section.
MTPT Decree 75/1994 makes interconnect between operators mandatory. It requires them to interconnect so as to make optimum use of national telecommunications resources. MTPT Decree 70/1994 requires interconnect at the tertiary level within Telkom's network for international services, at the secondary and tertiary level for interconnect with cellular operators, and at the primary level for local interconnect.
Interconnect costs are recovered through a mix of revenue sharing arrangements and interconnect charges. These are published through ministerial decrees. Only in a few cases, such as the interconnect arrangements between cellular and the international operators, are commercial interconnect arrangements negotiated. These commercial arrangements are confidential.
Mobile interconnect
Technical arrangements
all other networks must interconnect through Divnet rather than directly with the terminating network. Recently two exceptions were made to this rule. Cellular operators can now interconnect directly with the international operators and the regional cellular operators can interconnect directly with each other
the KSOs run local switching (primary centres plus local exchanges) only. All long distance calls requiring routing through a secondary or tertiary centre (ie trunk switching levels) must use Divnet. Many calls within a KSO region use Divnet.
Commercial arrangements
There are no interconnect payments between the KSOs and Divnet. A sender keeps all principle is used for all national calls between fixed line subscribers. The costs of Divnet are recovered through the revenue sharing arrangements for the joint operating schemes.
International:
Telkom bills end users on behalf of the international operators and passes to them the revenue collected (net of any interconnect payments). Historically interconnect between the international and national network was done on a revenue sharing basis, with Indosat paying 25% of its call revenue to Telkom. But, following Decree 108/1994, the international operators now pay fixed charges to Telkom.
Cellular Mobile:
The current interconnect arrangements between the cellular operators and Telkom are set out in Decree 05/1997. The end user pays the air time charge plus the appropriate PSTN charge depending upon the distance between the two users. Interconnect charges are levied on a revenue sharing basis. The percentage splits are designed to give the cellular operators a share of the profits which Telkom currently makes from long distance calls. In this way the Government hopes to stimulate use of the cellular networks.

Fixed networks
For domestic services, the incumbent operator is NTT. There are also around 120 competitors known as new common carriers (NCCs) which provide long-distance domestic, regional domestic, international, satellite and mobile services, and a few cable TV companies which are now entering the local telecoms market. These NCCs accounted for about 40% of the long distance market in 1996.
Despite the introduction of competition, NTT retains a near-monopoly in the local access market (other local access providers accounting for <1% of the market), with the result that all carriers are dependent on interconnection with NTT's local network in order to provide their own services.
Mobile networks
In July 1995, the PHS service was launched by three new groups. PHS service providers deployed their services mainly in the urban areas and applied different pricing policy from the cellular services.
The mobile communications service, including cellular and PHS, are now divided into 10 licence areas. In each area, a maximum of four licences are given for the cellular service and three for PHS.
4.8.3 Regulatory framework
MPT consults the Telecommunications Council on policy issues and administrative procedures, and refers applications from Type 1 carriers for proposed new or amended charges. If the Telecommunications Council approves the rates, MPT will approve them accordingly.
In January 1996, MPT released its deregulation package 'Promotion of Deregulation towards the Second Info-communications Reform'. The principal objectives of the reform are:
4.8.4 Commercial interconnect arrangements
Therefore, interconnect charges between operators were negotiated and must then submitted to the MPT for approval.
The MPT ensured that these interconnect prices were based on fully allocated cost of running intra-prefecture service. The prices excluded any access deficit contributions. They allowed for a return on assets employed of around 5% per annum. NTT's relevant cost base was subject to accounting separation and scrutiny by MPT.
For fixed to mobile calls, NTT billed the calling customer, kept the interconnect charge and passed the remainder of the retail tariff to the mobile operator. For mobile to fixed calls, the mobile operators billed the calling customer and passed the interconnect charge on to NTT. The interconnect charge in both directions was the same.
The 1996 review
From these and other examples, the MPT concluded that the interconnect framework does not allow for speedy and effective resolution of the disputes which inevitably arise.
New interconnection framework
Technical principles
- ministerial authorization will be required for interconnection tariffs setting out interconnection charges and technical rules
- the charges must be based on interconnection accounting
- interconnection must be provided on an unbundled basis and according to unbundled charges. (A recent report from the Telecommunications Council has recommended unbundling of subscriber terminating equipment, the local loop, local switching, inter-exchange transmission, and the signalling network.)
- terms and conditions for interconnection with essential facilities should be at least equal to those for comparable services provided by designated carriers
In September 1995, NTT announced its Open Network Plan (ONP). The ONP in principle allows the NCCs, including CATV companies which are planning to offer telephony services and Personal Handiphone Service (PHS) providers, to access the NTT network at multiple points of interconnect. In particular the plan:
ONP has the potential to increase competition and customer choice in local telecommunications services. However, local interconnect will not in practice be available until the start of 1998 at the earliest.
