THE COMMISSION OF THE EUROPEAN COMMUNITIES,

Having regard to the Treaty establishing the European Community,

Having regard to Council Regulation No 17 of 6 February 1962, the first Regulation implementing Articles 85 and 86 of the Treaty(1), as last amended by Regulation (EC) No 1216/1999(2), and in particular Articles 3 and 15(2) thereof,

Having regard to the complaints lodged on 18 March 1999, 19 July 1999 and 20 July 1999 by Mannesmann Arcor AG & Co. and 14 German regional fixed-network operators, alleging infringement of Article 82 of the EC Treaty by Deutsche Telekom AG and asking the Commission to put an end to that infringement,

Having regard to the Commission decision of 2 May 2002 to initiate proceedings in this case,

Having heard the undertakings concerned in accordance with Article 19(1) of Council Regulation No 17 and Commission Regulation (EC) No 2842/98 of 22 December 1998 on the hearing of parties in certain proceedings under Articles 81 and 82 of the EC Treaty(3),

Having consulted the Advisory Committee on Restrictive Practices and Dominant Positions,

Having regard to the report by the Hearing Officer,

Whereas:

I. THE FACTS

(1) This decision concerns unfair pricing contrary to Article 82(a) of the EC Treaty. The prices in question are charged to competitors and end-users by Deutsche Telekom AG ("DT") for access to its local networks. DT's local networks each consist of a number of local loops. In accordance with Article 2(e) of Directive 2002/19/EC of the European Parliament and of the Council of 7 March 2002 on access to, and interconnection of, electronic communications networks and associated facilities (Access Directive)(4), the local loop is the physical circuit connecting the network termination point at a subscriber's premises to the main distribution frame or equivalent facility in the fixed public telephone network.

(2) On 18 March 1999, Mannesmann Arcor AG & Co. lodged a complaint against DT under Article 82 of the EC Treaty and against Germany under Article 86 of the EC Treaty.

(3) The Commission received two further complaints in respect of the same facts, one on 19 July 1999, from TeleBeL GmbH and seven other companies (see recital 9) (Case COMP/C-1/37.37.58) and one on 20 July 1999, from EWE TEL GmbH and five other companies (see recital 10) (Case COMP/C-1/37.579). All of these additional 14 complainants are German local and regional telecommunications operators active in different German towns or cities.

(4) The main contention in all three complaints is that the margin between the prices DT charges its competitors for unbundled access to local loops in Germany and the prices it charges end-users for access to its fixed network is not sufficient to enable its competitors to compete with it to provide end-user access over local networks. The main accusation made against Germany is that the German regulatory authority for telecommunications and posts (Regulierungsbehörde fur Telekommunikation und Post, abbreviated to RegTP and hereinafter referred to as "the regulatory authority") has fixed the wholesale charges at a level exceeding the retail charges.

(5) Charges for access to local networks are partly regulated by the regulatory authority, but this decision is concerned with unfair prices which have been set by DT itself in the exercise of its own commercial freedom, and for which it is directly responsible.

II. THE UNDERTAKINGS

A. THE PARTY AGAINST WHOM THE COMPLAINTS ARE MADE

(6) DT is the incumbent telecommunications operator in Germany. It operates the fixed telephone network originally built using public resources. DT was at one time wholly owned by the German State. On 18 November 1996, 25 % of the equity was sold on the open market to private investors: this package amounted to 714 million shares known as "T" shares, and was sold for DEM 20,1 billion. Following a capital increase in June 1999, the percentage of shares owned by private investors rose to 33 %. At that time a 65 % stake was still held by the German State (43 % direct and 22 % through the German recovery bank Kreditanstalt für Wiederaufbau, or "KfW"), while 2 % was held by France Télécom. When DT took over the United States mobile operator VoiceStream/Powertel in 2000, the State and KfW gave up part of their holdings. France Télécom sold its shares back to DT. Currently, 30,92 % of the shares are held by the State, 12,13 % by KfW, and 56,95 % by institutional and private investors.

(7) Before the full liberalisation of telecommunications markets, DT enjoyed a legal monopoly in the retail provision of fixed-line telecommunications services. Since 1 August 1996, when the Telecommunications Act ("the Act")(5) entered into force, the German markets in the provision of infrastructure and in the provision of telephone services have been liberalised. DT now faces varying degrees of competition from alternative operators on the two markets.

B. THE COMPLAINANTS

(8) The complainant in Case COMP/C-1/37.451 is Mannesmann Arcor AG & Co., one of Germany's largest fixed-network operators, which offers end-users a wide range of telephone services. In 2000 Mannesmann AG was taken over by Vodafone Airtouch plc(6). Since April 2001 the complainant has traded under the name Arcor AG & Co. (hereinafter "Arcor"). On 30 September 1998 Arcor concluded an outline agreement with DT for local loop unbundling, in which charges were agreed only provisionally, pending authorisation by the regulatory authority, as required by the German rules on price regulation.

(9) The complainants in Case COMP/C-1/37.578 are TeleBeL GmbH (Wuppertal), CNB GmbH (Bremen), Citykom GmbH (Münster), HTN GmbH (Hanover), Hamcom GmbH (Hamm), KomTel GmbH (Flensburg), DOKOM GmbH (Dortmund) and KielNet GmbH (Kiel).

(10) The complainants in Case COMP/C-1/37.579 are EWE TEL GmbH (Oldenburg), HanseNet GmbH (Hamburg), ISIS Multimedia Net GmbH (Düsseldorf), NetCologne GmbH (Cologne), tesion Communikationsnetze Südwest GmbH & Co. KG (Stuttgart) and VEW TELNET GmbH (Dortmund).

(11) All 14 complainants in Cases COMP/C-1/37.578 and COMP/C-1/37.579 are local and regional fixed-network operators with geographically restricted licences, who connect end-users to their own networks within their licensed territory, in so far as their networks are within reach and operational. To connect customers that they cannot reach with their own networks these complainants need unbundled access to DT's local loops (see recital 64 et seq.). All 14 have concluded agreements with DT concerning local loop unbundling.

III. FACTS AND FIGURES

(12) In order to compete with DT, competitors secure network access either by using their own infrastructure (optical fibre, cable television, power lines, etc.), or by using DT's local network on the basis of unbundled access to local loops. The latter option is less cost-intensive, and gives even financially weaker competitors, who are unable to build complete infrastructures of their own, direct access to the German retail market. Countrywide providers of telecommunications services also depend on shared use of existing infrastructure. But in the case of telephone calls, as a result of network interconnection, alternative operators wishing to provide countrywide services in Germany no longer face any comparable bottleneck.

(13) New entrants do not have network infrastructures of their own that are as extensive as those of DT, and with traditional technologies they are unable to match the economies of scale and the coverage of the incumbent operator, which rolled out its local network over a long period under the protection of exclusive rights, and funded its investment out of monopoly rents(7).

(14) DT offers access to its local networks to other telecommunications operators and to end-users. The rules governing telecommunications in Germany regulate the two types of access in different ways.

A. WHOLESALE ACCESS: FULL UNBUNDLING

(15) At local level a distinction can be made between two different forms of access to incumbents' fixed telephone networks: one is full local loop unbundling, and the other is line sharing, or shared use of local loops. The charges for the two forms of access are different. This decision relates only to fully unbundled access to DT's local loops.

(16) With effect from June 1997 DT was required to offer its competitors fully unbundled access to the local loop(8). The requirement was imposed by decision of the Federal Ministry of Posts and Telecommunications in May 1997(9); at that time no such obligation yet existed under Community law(10). DT challenged the decision before the administrative courts(11); DT's application was finally dismissed by the Federal Administrative Court in 2001. On 30 August 1998, on the basis of this unbundling requirement, an outline agreement on unbundled access to DT's local loops was reached between DT and Mannesmann Arcor.

(17) Under German telecommunications law, charges for access to the local network must be cost-oriented(12) and must be authorised in advance by the regulatory authority(13). When deciding whether to authorise the wholesale prices that DT charges other operators, the regulatory authority has to satisfy itself that they correspond to the cost of efficient service provision(14), contain no special extra charges or discounts(15), and do not confer anticompetitive advantages on some operators only(16).

(18) In March 1998, acting under these provisions in response to an application made by DT on 23 December 1997, the regulatory authority for the first time authorised monthly net charges for unbundled access to DT's local loop (all charges specified in this decision are net charges)(17). DT had requested authorisation for a monthly charge of EUR 14,73 for the rental of a basic analogue local loop(18). DT had also applied for one-off charges of EUR 309,84 for opening a new connection, no additional work being needed(19), and EUR 135,49 for taking over an existing serviceable connection(20). On 9 March 1998 the regulatory authority rejected part of the costing submitted by DT, and authorised a monthly charge of EUR 10,56 for the rental of a local loop. It authorised the one-off charges requested for the time being. DT did not at that time charge its competitors separately for discontinuing access to local loop; the cost of discontinuance was included in the charges for access provision.

(19) While granting this partial authorisation, the regulatory authority also ordered DT to submit a more detailed cost calculation, by the middle of 1998, using the cost accounting system DT had recently introduced (INTRA). It told DT that the corrections ought to bring the charges finally sought for unbundled access for competitors to well below EUR 10.

(20) On 5 June 1998, contrary to these guidelines, DT submitted a fresh application to the regulatory authority seeking authorisation for a monthly charge of EUR 24,16. It also applied for one-off charges of EUR 384,58 for a straightforward new connection and EUR 323,67 for a straightforward takeover. Under the terms of the Act, the regulatory authority was required to decide on the application within 10 weeks, which meant that the deadline was 30 November(21). But on 27 November 1998, DT, having learnt that the regulatory authority intended to increase the monthly charge to EUR 11,86, withdrew its application, on the recommendation of the Federal Minister for Economic Affairs. The same day the regulatory authority decided to suspend the proceedings and to extend the validity of its provisional authorisation of 9 March 1998, which was now to continue until 30 April 1999(22).

(21) On 20 January 1999 the Administrative Court of Cologne, on an application for interim measures brought by Mannesmann Arcor, held that the regulatory authority was entitled to reach a decision on the level of charges of its own motion, and that in this particular case it was bound to do so(23). However, DT immediately lodged a new application with the regulatory authority, seeking authorisation for a monthly charge of EUR 19,07 and one-off charges of EUR 224,26 for a straightforward new connection and EUR 186,44 for a straightforward takeover.

(22) On 10 February 1999 the regulatory authority authorised a monthly local loop access charge of EUR 12,99 for a basic line(24). It authorised one-off charges of EUR 100,50 for a straightforward new connection and EUR 97,99 for a straightforward takeover. It also authorised a one-off discontinuance charge of EUR 55,07, which DT now showed separately from the charges for access provision. In so far as the charges applied for were higher than these, the regulatory authority rejected DT's application. The authorisation was valid until 31 December 2001.

(23) On 19 January 2001, DT lodged a new tariff application with the regulatory authority seeking a monthly charge of EUR 17,40 for a basic line and one-off charges of EUR 119,51 for a straightforward new connection, EUR 127,04 for a straightforward takeover, and EUR 104,41 for discontinuance of access to the local loop(25) in the case of a basic line. Along with the application DT submitted calculations of the costs of these services based on its own internal cost accounting system; it expressly stated that under the relevant rules of German law these were the only calculations that could be considered for purposes of the authorisation of charges(26).

(24) The regulatory authority decided on the application on 30 March 2001,(27); with effect from 1 April 2001 it authorised a monthly charge of EUR 12,48 for the rental of a basic line(28), and one-off charges of EUR 92,59 for a straightforward takeover and EUR 86,51 for a straightforward new connection(29). The same decision authorised discontinuance charges of EUR 38,06 for a straightforward takeover and EUR 59,24 for a new connection requiring work on DT's cable distribution frame. In so far as the charges applied for were higher than these, the regulatory authority rejected DT's application. The regulatory authority based this partial authorisation essentially on the system of analytical cost accounting developed by the consultant WIK(30), which set out to identify the long-run incremental costs of unbundling in a more theoretically rigorous way(31), as DT's own cost calculations did not meet the legal requirements in every respect.

(25) On 11 April 2002(32), the regulatory authority approved DT's application to reduce one-off charges with effect from 1 April 2002, bringing the charge for a straightforward new basic connection to EUR 81,12, for a straightforward takeover to EUR 70,56, and for discontinuance to EUR 34,94 (with simultaneous transfer of the customer) or EUR 50,71 (without simultaneous transfer)(33). By decision of 30 April 2003, the regulatory authority(34) reduced the monthly charge to EUR 11,80 with effect from 1 May 2003.

B. RETAIL ACCESS

(26) DT offers its end-users two basic variants of access to the fixed network. These are the traditional analogue connection (marketed under the brand name "T-Net") and the digital narrowband connection (integrated services digital network, or ISDN, brand name "T-ISDN"). Both these variants of end-user access can be provided over DT's existing copper pair network. DT also offers end-users a broadband connection allowing broadband services such as faster Internet access (asymmetrical digital subscriber line, or ADSL, brand name "T-DSL"), which it provides by upgrading an existing T-Net or T-ISDN line.

(27) According to information provided by DT(35), the number of DT's analogue (T-Net) and digital (T-ISDN) retail lines, including all lines with an ADSL upgrade, developed as follows between 1998 and 2002:

Table 1

>TABLE>

(28) Of the total number of local loops, an increasing proportion is being equipped with ADSL technology, allowing faster transmission of larger volumes of data. According to information provided by DT, the roll-out of ADSL (T-DSL) end-user connections developed as follows between 1998 and 2002(36):

Table 2

>TABLE>

(29) DT's retail tariffs are made up of two components: a basic monthly charge, which depends on the quality of the line and services supplied, and a one-off charge for a new connection or takeover of a line, depending on the work needed at the two ends of the line(37).

(30) DT's retail prices for analogue and ISDN lines are regulated under the German price cap system, in which a price adjustment guideline is set for a basket of services, whereas retail tariffs for T-DSL are not subject to any advance regulation.

(a) CHARGES FOR ANALOGUE AND ISDN LINES (T-NET AND T-ISDN)

(31) Unlike the prices that DT charges its competitors for access to the local network (see recital 15 et seq.), its retail tariffs for analogue and ISDN lines are not regulated individually in line with cost-orientation principles, but instead fall under what is known as the price cap system. Prices for retail subscription to DT's fixed telephone network and for telephone calls made are not regulated for each service separately, depending on the individual cost of that service: they are regulated for a block of services at a time, with different services being grouped together in what is called a "basket"(38).

(32) Under the German telecommunications charges order, the price cap method is the preferred tariff regulation tool: strict cost orientation is applied to an individual retail service only if that service cannot be allocated to one of the predetermined baskets(39). This means that the firm whose charges are regulated has some discretion to fix its prices on a commercial basis. The price cap system is made up of one price cap decision, laying down the division of services into baskets, the price adjustment guideline and other general terms for a specified period, and other decisions reached on individual applications for adjustments to charges during that price cap period.

(33) A basket is to be composed of services which are in a comparable situation with respect to competition(40). A starting charge level is first determined for all the services grouped in a basket(41), and a target, known as the price cap index, is set for the movement of the basket price over a specified period(42). Price adjustment guidelines have to be arrived at taking account of the general rate of price increases, the anticipated productivity gains of DT, and the relationship between the starting charge level and the long run incremental cost of efficient service provision(43).

(aa) Price cap periods 1998/1999 and 2000/2001

(34) The price cap mechanism for retail fixed-network charges was introduced by decision of the Federal Ministry of Posts and Telecommunications in December 1997(44), and was taken over by the regulatory authority from 1 January 1998. Two baskets were established, one for services to residential customers and the other for services to business customers. Each basket contained access services (standard analogue and ISDN subscriptions), the full range of telephone products offered by DT, such as local, regional, long-distance and international calls, and also satellite calls and optional tariffs.

(35) Under the Ministry's original decision, dated 17 December 1997, DT was to reduce the aggregate price for each basket by 4,3 % in the first price cap period, that is to say the two years running from 1 January 1998 to 31 December 1999. When the first price cap period ended, on 31 December 1999, the regulatory authority decided essentially to maintain the composition of the baskets and to lower the basket prices by a further 5,6 % in the second price cap period, which ran from 1 January 2000 to 31 December 2001(45). In each price cap period the average price index(46) was to be smaller or no bigger than the price cap index(47). These index figures are intended to reflect productivity and efficiency gains on DT's part and the rate of price increases in the economy as a whole, as a result of inflation for example, during the particular price cap period.

(36) Within this framework of binding price reductions, DT could modify the charges for individual components of the basket as it wished. In formal terms, though, any adjustment of the charges needed authorisation by the regulatory authority. DT was entitled to take the initiative and to apply for authorisation at any time; there was no restriction on the number of adjustments that could be made in any one price cap period. In the price cap system, planned adjustments to charges can as a rule be authorised if the average price of a basket does not exceed the imposed price cap index(48), and there are clearly no discounts or discriminatory terms(49). Thus DT was free to increase the charges for one or more components of the basket provided that the overall ceiling for the basket was not exceeded. This meant that an increase that exceeded the price ceiling for a basket was possible only if at the same time the prices of other components of the same basket were reduced. But the price cap system made no provision for mandatory minimum basket prices, and there was nothing to prevent DT from reducing all of the charges grouped in a basket beyond the rates of reduction imposed.

(37) In the first two price cap periods, DT reduced the retail prices in both baskets substantially, going far beyond the mandatory reductions(50). In terms of volume of turnover, in the first price cap period, running from January 1998 to December 1999, the reductions amounted to EUR [...] for the residential basket and EUR [...] for the business basket. Taking out the mandatory reduction of 4,3 %, the additional, unimposed reductions for the two baskets together amounted to EUR [...](51). In the second price cap period, running from January 2000 to December 2001, the additional, unimposed reductions, after the mandatory reduction of 5,6 % is taken out, amounted to a further EUR [...] in the residential customers basket, and EUR [...] in the business customers basket(52). This means that over a period of four years, DT undertook voluntary price reductions that went beyond what was required by a total of EUR [...](53).

(38) The reductions applied to call charges only: the monthly and one-off access charges for standard analogue telephone connections remained unchanged throughout the entire time from 1998 to the end of 2001.

(39) In that period DT's basic monthly charge for retail access to a standard analogue telephone line ("T-Net standard") was always EUR 10,93. DT claims that this charge does not cover the cost to DT of providing end-users with analogue access to the telephone network. DT contends that it has not yet fully eliminated the revenue shortfall on retail access to the fixed network(54). DT's predecessor, Deutsche Bundespost, had permitted this shortfall essentially on social grounds: Deutsche Bundespost offered users access to the telephone network below cost, and made up its losses on access out of above-average revenue from calls, and especially its charges for international calls.

(40) Until 31 March 2000 the basic monthly charge for an ISDN connection was EUR 19,56 for T-ISDN multi-device mode (Mehrgeräteanschluss), simple; EUR 20,45 for T-ISDN multi-device mode, standard; EUR 22,67 for T-ISDN, multi-device mode, comfort; EUR 26,23 for T-ISDN point-to-point mode (Anlagenanschluss), simple; EUR 28,45 for T-ISDN point-to-point mode, standard; and EUR 30,68 for T-ISDN point-to-point mode, comfort(55). On 17 December 1999, DT applied for authorisation to reduce these prices to EUR 19,78 for T-ISDN multi-device mode, standard, EUR 21,99 for T-ISDN multi-device mode, comfort, EUR 25,56 for T-ISDN point-to-point mode, simple and standard, and EUR 28,12 for T-ISDN point-to-point mode, comfort, and on 16 February 2000 the regulatory authority granted the authorisation applied for with effect from 1 April 2000(56). These are therefore the prices that applied until the end of the original price cap scheme.

(41) Throughout the whole price cap period 1998 to 2001 DT's one-off retail charges for analogue and ISDN lines of all kinds amounted to EUR 22,22 for a takeover of a serviceable connection and to EUR 44,45 for the provision of a new serviceable connection with no special work required. There were no discontinuance charges for DT customers.

(bb) Price cap period 2002

(42) A new price cap system was approved by the regulatory authority on 21 December 2001 and has been in force since 1 January 2002(57). On 23 May 2001, the regulatory authority published preliminary guidelines for new price cap arrangements to apply from 2002(58), and in October 2001 it announced its intention of adjusting the composition of the baskets and the imposed reductions in the basket prices, known as "X factors"(59). The decision of 21 December 2001 was in line with what had been proposed. In place of the two baskets for residential and business customers, the new system uses four baskets, for end-user lines (basket A), local calls (basket B), domestic long-distance calls (basket C), and international calls (basket D)(60).

(43) End-user lines are now in a separate basket with a negative X factor; this obliges DT to increase charges, restructuring its tariffs further in order to put an end to the existing shortfall on subscriber lines(61). With the imposed X factor of - 1, and an inflation rate of 3,1 %(62), DT is entitled under the new price cap system to increase charges for end-user lines by 4,1 % a year, or 12,3 % over the three-year period covered by the new price cap procedure(63).

(44) On 15 January 2002, DT informed the regulatory authority that it proposed to increase its monthly charges for analogue and ISDN lines by an initial EUR 0,56 each(64). By a decision of 13 March 2002, the regulatory authority made a finding that DT had complied with all the values laid down for increases in the various end-user line charges in basket A, as the average level of charges for all the services in basket A had risen by 4,04 %(65). From 1 May 2002 the monthly charge for an analogue line (T-Net) became EUR 11,49, and the monthly charge for T-ISDN became EUR 20,34 for multi-device mode, standard, and EUR 22,55 for multi-device mode, comfort. The prices of the other T-ISDN variants remained unchanged.

(45) Lastly, on 31 October 2002 DT submitted an application to the regulatory authority for authorisation to increase the monthly rental charge for a T-Net analogue telephone line by EUR 0,99 to EUR 12,48, and to increase the one-off takeover charge for T-Net and T-ISDN lines by EUR 13,40 to EUR 35,62, with effect from 1 February 2003. But in its decision, adopted on 19 December 2002, the regulatory authority authorised only an increase of EUR 0,33 in the monthly charges, bringing them to EUR 11,82, and otherwise refused the application. Thus it did not authorise the increase in the one-off takeover charge that DT had applied for(66). In support of its decision, RegTP specifies that these increases would not have been consistent with the current price cap index figures anymore. DT's one-off charges for all variants of T-Net and T-ISDN continue to stand at EUR 22,22 for a takeover and EUR 44,46 for a new connection. DT still collects no discontinuance charges from its own end-users.

(b) CHARGES FOR ADSL LINES ("T-DSL")

(46) Unlike the tariffs for analogue and ISDN lines, T-DSL tariffs are not subject to advance regulation under the price cap system. The prices of T-DSL services are set by DT at its own discretion, but may be reviewed ex post(67).

(47) From July 1999 to July 2000, DT offered T-DSL only over T-ISDN lines, at a price of EUR 22,74 monthly and a one-off EUR 100,93 for installation. Between August and December 2000, it offered T-DSL over T-Net lines at EUR 13,17 a month, and over T-ISDN lines at EUR 6,56 a month. From January 2001 to February 2002,the monthly charge for a T-DSL upgrade on a T-Net line was EUR 17,59, and on any variant of T-ISDN line EUR 8,77(68). This meant that until 31 July 2000 the total price for T-DSL/T-ISDN multi-device mode, standard, was EUR 43,19, and for T-DSL/T-ISDN multi-device mode, comfort, EUR 45,41. From 1 August 2000 to 31 December 2000, the total price for T-DSL/T-Net was EUR 24,10, for T-DSL/T-ISDN multi-device mode, standard, EUR 26,34, and for T-DSL/T-ISDN multi-device mode, comfort, EUR 28,55. From 1 January 2001 to 24 February 2002, the total price of T-DSL/T-Net was EUR 28,52, for T-DSL/T-ISDN multi-device mode, standard, EUR 28,55, and for T-DSL/T-ISDN multi-device mode, comfort, EUR 30,76.

(48) On 2 February 2001, following a number of complaints from competitors, the regulatory authority initiated an ex post investigation of DT's ADSL prices, on the ground that there might be anticompetitive below-cost selling. The regulatory authority came to the conclusion that DT's monthly charge for T-DSL services over a T-ISDN standard line covered only [...] % of costs. In the same decision the regulatory authority also found that DT's one-off installation charge for T-DSL services covered only [...] % of costs(69).

(49) The regulatory authority nevertheless decided to take no action against these prices, and to close its investigation, because in two further decisions taken on 30 March 2001, it ordered DT to make it possible for its competitors to sell on to other customers local network wholesale services for connections and local and urban calls ("resale"), and to make joint use of the local loop ("line-sharing")(70). But DT did not comply with these orders as expected, and on 18 December 2001 the regulatory authority decided to reopen the abuse proceedings and to investigate the T-DSL tariffs once again.

(50) On 15 January 2002, DT announced that it would be reducing the monthly charge for T-DSL/T-Net from EUR 17,59 to EUR 17,23, and increasing the monthly charge for T-DSL/T-ISDN from EUR 8,78 to EUR 11,20(71). DT has been applying these charges since 25 February 2002. On this basis the current total monthly retail prices are EUR 28,72 for T-DSL/T-Net, EUR 31,54 for T-DSL/T-ISDN multi-device mode, standard, and EUR 33,75 for T-DSL/T-ISDN multi-device mode, comfort(72). As a result of an increase in the T-Net price on 1 February 2003, T-DSL/T-Net now costs EUR 29,05.

(51) From 1 August 2000, DT customers had to pay a one-off charge of EUR 44,46 for the provision of a T-DSL upgrade on a T-Net line or any variant of T-ISDN line. On 15 January 2002, DT announced that it would be increasing this one-off charge to EUR 64,61 with effect from 1 July 2002, and to EUR 86,16 with effect from 1 January 2003. On 22 January 2002, the regulatory authority terminated its abuse proceedings on the ground that the price situation did not now give any cause to suspect that there might be "price dumping" within the meaning of the Act(73).

IV. ASSESSMENT

A. APPLICABILITY OF ARTICLE 82 OF THE EC TREATY

(52) Operators of fixed telecommunications networks and telecommunications services are subject to Articles 81 and 82 of the EC Treaty, because by providing access to fixed networks and services over such networks on a commercial basis they are carrying out an economic activity(74). DT is a registered business undertaking that operates a fixed telecommunications network accessible to the public and provides related services. It therefore constitutes an "undertaking" within the meaning of Articles 81 and 82 of the EC Treaty.

(53) For the provision of network access and related services, DT is subject to sector-specific regulation under Community legislation and the national laws and regulations that implement the Community legislation. DT contends that the Commission is not entitled to proceed against charges which have previously been the subject of regulatory decisions at national level, owing to the division of responsibility between the Commission and the German regulatory authority(75). DT argues that all of the charges at issue were imposed by the regulatory authority, so that DT was left no scope for independent commercial decisions against which competition proceedings might be brought at Community level(76). If there is any infringement of Community law, the Commission should not be acting against an undertaking whose charges are regulated; its proper course is rather to bring infringement proceedings against Germany under Article 226 of the EC Treaty(77).

(54) Contrary to DT's view, however, the Court of Justice of the European Communities and the Court of First Instance of the European Communities have consistently held that the competition rules may apply where the sector-specific legislation does not preclude the undertakings it governs from engaging in autonomous conduct that prevents, restricts or distorts competition(78). This is particularly so in the case of complaints submitted to the Commission regarding possible violations of the EU competition rules. In such cases the Commission has a duty to investigate, and if necessary to order appropriate remedies.

(55) Accordingly the Commission stated in the notice on the application of the competition rules to access agreements in the telecommunications sector: framework, relevant markets and principles (access notice), that cases might be subject both to the competition rules and to national or European sector-specific measures, most notably internal market measures. The Commission had this to say: "In the telecommunications sector, the ONP Directives aim at establishing a regulatory regime for access agreements. Given the detailed nature of ONP rules and the fact that they may go beyond the requirements of Article 86 (now Article 82), undertakings operating in the telecommunications sector should be aware that compliance with the Community competition rules does not absolve them of their duty to abide by obligations imposed in the ONP context, and vice versa"(79).

(56) The notice goes on: "Articles 85 and 86 of the Treaty (now Articles 81 and 82) apply in the normal manner to agreements or practices which have been approved or authorised by a national authority, or where the national authority has required the inclusion of terms in an agreement at the request of one or more of the parties involved"(80).

(57) This decision concerns abuse by DT in the form of a margin squeeze generated by a disproportion between wholesale charges and retail charges for access to the local network. The charges in both cases are subject to sector-specific regulation (see recitals 17 et seq. and 31 et seq.), but DT has a commercial discretion which would allow it to restructure its tariffs further so as to reduce or indeed to put an end to the margin squeeze (see recital 163 et seq.). The margin squeeze therefore constitutes the imposition of unfair selling prices within the meaning Article 82(a) of the Treaty.

B. DOMINANT POSITION

(58) DT enjoys a dominant position on the German markets in access to local fixed networks, both wholesale and retail; in the case of retail access, the market has to be further divided into narrowband and broadband access. DT does not dispute this definition of the markets, nor the fact that it has a dominant position on the markets thus defined.

(a) RELEVANT PRODUCT OR SERVICE MARKETS

(59) The relevant product or service markets are markets in the provision of local access to fixed telecommunications networks. According to the Commission guidelines on market analysis and the assessment of significant market power under the Community regulatory framework for electronic communications networks and services(81), Markets in access are to be distinguished from markets in the services provided to end-users over the networks, such as telephone call services for example.

(60) As a result of the liberalisation of voice telephony services in Germany, a number of competitors have entered the market in recent years and now offer telephone services to end-users. The service offerings of new entrants have developed quickly, particularly for international calls, and to a lesser extent also for domestic long-distance and local calls. Given the high cost of building an alternative local access infrastructure, and the resulting dependence of the new entrants on the service offerings of the incumbent, competitors provide a far smaller proportion of access services to end-users in Germany. Whilst DT's share of the market in international and domestic long-distance call markets has fallen substantially, DT still delivers the bulk of local calls and of access services to end-users. Thus competition between new entrants and the incumbent operator continues to be concentrated on business customers and urban areas.

(61) Two separate markets in access to the local network have to be distinguished: the wholesale market, which is the upstream market in local network access offered by infrastructure owners to their competitors, and the retail market, which is the downstream market in access services offered by telecommunications operators to their own end-users(82).

(62) The two markets, in wholesale and retail access, are closely linked to each other. Infrastructure owners provide access services both to their end-users, either directly or through an associated undertaking, and to other operators who have no networks of their own or whose networks are geographically restricted. These competing operators need network access as an input to their business, in order to be able to offer access and services to their own end-users.

(63) According to the guidelines mentioned in recital 59, on the retail access market a further segmentation has to be made between narrowband access over analogue copper lines and ISDN lines, on the one hand (see recital 74 et seq.), and broadband access to local loops for high-speed data transfer, such as ADSL, on the other (recital 78 et seq.)(83). This additional segmentation does not apply to wholesale markets, because so far it is only to a very limited extent that DT offers its competitors narrowband and broadband wholesale access separately (recital 64 et seq.).

(aa) Upstream market in wholesale access

(64) The local loop can be rented to competitors as an input to their business. In Germany local loop unbundling now requires the incumbent operator to allow access to its network, and since the beginning of 1998, a new market in wholesale local network access has developed, upstream from the retail access market. So far DT has concluded about 100 local loop transfer contracts with other providers. The competitor pays DT a charge for this wholesale service.

(65) None of the other owners of local telecommunications access infrastructure, such as local authorities and regional carriers, some of which are among the complainants in the present proceedings, has yet been able to build up local networks equivalent to those of DT. They have established local access networks only in geographically restricted areas, mainly in and around individual towns and cities. From the point of view of competitors seeking entry to the German market, the density of DT's fixed network, together with the technological facilities it offers, make wholesale access to that network the only commercially viable option.

(66) According to the provisions of Directive 97/33/EC of the European Parliament and of the Council of 30 June 1997 on interconnection in telecommunications with regard ensuring universal service and interoperability through application of the principles of open network provision (ONP) and Directive 98/61/EC of the European Parliament and of the Council of 24 September 1998 amending Directive 97/33/EC with regard to operator number portability and carrier pre-selection, telephone users must have the possibility, while maintaining their basic subscription with the original operator, to switch to another operator either with each individual telephone call (carrier selection) or for all calls (carrier preselection)(84). Carrier selection and carrier preselection do not give competitors access to comparable infrastructure, because they enable them only to provide narrowband services. Furthermore, carrier selection and preselection were so far possible in Germany only for long-distance calls, for which there is now some degree of competition, but not for local calls, contrary to the obligations laid down in the Community directives on open network provision(85). Economically, carrier selection and preselection differ from local network access in that selection and preselection charges are based on the duration of calls, whereas for local network access there are one-off and monthly charges.

(67) The wholesale local access market cannot at present be further subdivided into narrowband and broadband services. Until recently DT granted local network access only for the entire bandwidth spectrum, so that competitors at the wholesale level had to rent all bandwidths in the local loop; they then freely decided whether they wanted to offer end-users narrowband or broadband services or both. A division between bandwidths has been possible only since DT at the end of 2001 concluded an agreement with a competitor, QSC AG, providing for line sharing, and the regulatory authority determined the charges for line sharing on 15 March 2002. So far only three line-sharing agreements have been concluded(86). Thus in practice line sharing is not yet used to an extent sufficient to make it a separate wholesale access market in Germany.

(bb) Downstream markets in retail access

(68) Local loops are primarily a form of infrastructure that allows access to and the delivery of retail telecommunications services. In Germany, interconnection and carrier selection and preselection have produced an opening to competition only on the long-distance and international calls markets; indeed despite an amendment to the Act on 1 December 2002 carrier selection and preselection until recently did not allow alternative operators to deliver local call services (call origination).

(69) Local networks are therefore the key infrastructure for providing local access services to end-users, that is to say the initial connection and long-term rental of local loops, and for local telephone calls. Local networks remain largely within the control of the respective network owner.

(70) The provision of access for end-users to the local loop and the provision of services delivered to end-users over the local loop form two separate relevant markets, in services which are not substitutable. On the demand side, customers are not in a position to switch from one market to the other, either because of an increase in price or for any other reason: they cannot replace retail network access by retail services, because the two products do not perform the same functions. The price structures of access and services are also very different. Access prices have remained relatively stable since local loop unbundling was made mandatory in Germany, but the prices of telephone services have fallen substantially. Access and services markets are different on the supply side too, because given the different functions the mere fact that new entrants provide telecommunications services will not under any foreseeable circumstances put them in a position to compete with DT in the provision of local access.

(71) The finding that a separate access market exists is in accordance with the practice followed by the Commission in its decisions(87) and with Commission Directive 96/19/EC(88) amending Directive 90/388/EEC of 28 June 1990 with regard to the implementation of full competition in telecommunications markets(89), in which the Commission distinguishes the following fixed telephony retail services: the initial connection of a local loop, the monthly line rental, local calls, regional calls and long-distance calls.

(72) In the same vein, in its communication, "Unbundled access to the local loop: enabling the competitive provision of a full range of electronic communication services, including broadband multimedia and high-speed Internet"(90) the Commission stated that network access and individual services delivered over the network were not currently substitutable for one another, and would therefore be considered as forming different relevant markets.

(73) The further segmentation of the retail access market into one market for narrowband services and another for broadband services is based on the finding that those are the two main categories of retail services offered over the local loop, with different features from the point of view both of demand and of supply.

1. Narrowband access services

(74) Narrowband access services to end-users form a market separate from the market in broadband access services. In Germany, the market in narrowband access services is already extensively developed and mature, with a number of alternative operators in place offering similar services over their own networks. Most of the new entrants in Germany offer local or regional access services, and have already secured a substantial number of end-users in the areas in which they operate; as well as the traditional analogue connections, most of them offer their customers ISDN connections too.

(75) Narrowband access services include access to analogue lines as well as to traditional digital lines (ISDN) offering bi-directional transmission capacities up to 64 kilobits per second (kbit/s). Such capacities are sufficient for transmitting voice communications, but too limited for the large volumes of data in video files for example. Internet access is possible over narrowband lines, but only in the form of dial-up access with metered tariffs, no flat-rate offer for narrowband Internet access being currently available.

(76) Narrowband access services are usually offered to residential customers who make no demands or only limited demands on Internet access in terms of transmission quality, quantity, and speed. These services are less suitable for business customers, and are not offered to them to any appreciable extent. Their prices are therefore significantly lower than those for broadband access services.

(77) A growing number of end-users are having their connections upgraded from analogue or ISDN lines to broadband ADSL lines in order to improve the speed and quality of transfer. But the contrary form of consumer behaviour, a downgrading from broadband to narrowband connections, does not occur to any appreciable extent, so that substitutability between the two categories of service can be said to be one-way.

2. Broadband access services

(78) Broadband retail access services, delivered in the form of ADSL connections over the local network or via other access technologies, allow high-speed communication to be provided, and form a market separate from the market in narrowband retail access services. ADSL services are network access services provided over an asymmetrical digital subscriber line, with transmission capacities of 128 kbit/s upstream (from the user to the outside world) and of 512 kbit/s downstream (from outside to the user). Some services, such as video on demand, can be provided to a satisfactory quality only over broadband connections(91).

(79) Intensive Internet users with high demands in terms of transmission capacity, quality, security, and speed, and who also attach importance to permanent connectivity, for the most part make use of ADSL services. The special demand structure for broadband connections, as compared with narrowband, also derives from flat-rate pricing, which for intensive Internet users of this kind is cheaper than the traditional charges for metered connections. The only comparable alternative access technology available to residential customers in Germany is cable, but cable is available only in very restricted geographic areas.

(80) Business customers likewise for the most part want ADSL broadband services. But for these customers, fibre-optic networks, leased lines, wireless local loops and satellite connections are also attractive options, because although their costs are higher they are better adapted in certain cases to business customers' particular requirements.

(81) This end-user access market is therefore confined to ADSL broadband access services provided to residential customers. In contrast to the market in narrowband access services, this market has grown very unevenly in Germany. In particular, it has developed later(92).

(82) Narrowband and broadband markets need to be clearly distinguished on the supply side too. An operator wishing to convert from narrowband to broadband access services must be prepared to incur substantial additional costs. Along with heavy investment in plant, most notably for special terminal equipment such as digital subscriber line access multiplexers or DSLAMs, substantial spending on marketing and advertising will be needed in order to secure customers for these new services.

(b) LACK OF ALTERNATIVE INFRASTRUCTURE

(83) DT's local networks are not the only technical infrastructure allowing access services to be provided to other operators or to end-users. The main conceivable alternatives to the local networks on all three of the relevant markets described above are fibre-optic networks, wireless local loops, satellites and upgraded cable TV networks. However, none of these alternatives can yet be considered equivalent to the local network in Germany, because they are not sufficiently developed in order to be substitutable. DT currently has about 19000 broadband Internet connections to end-users working on the basis of alternative technologies, and its competitors about 86000(93).

(84) Fibre-optic networks are currently competitive only on upstream interfaces, and in the retail distribution network in special niches, such as networks connecting office buildings or in narrowly defined geographical areas.

(85) Local network access via wireless local loops will in the short and medium term most probably be useful to professional clients and small firms, or meet the particular requirements of individual residential customers; for the great majority of residential customers wireless local loops are likely to remain uneconomical.

(86) Satellites are an alternative mainly for commercial users. At present there are few offers of bi-directional services (send and receive by satellite), which would make satellites completely independent of the local networks. The necessary reservation of bandwidth on satellite transponders and the need to build additional plant in bi-directional ground stations make satellite communication very expensive, and practically out of the question for residential use. For this reason satellite operators have not yet succeeded in penetrating the market in public telecommunications services.

(87) Cable networks were designed for one-way television transmission, and require costly and time-consuming upgrades for the provision of two-way telecommunication services. This has so far been done in only two of the nine German "cable regions", namely in Hessen (where the provider is named "iesy") and in North Rhine-Westphalia (where the provider, named "ish", has since been declared insolvent), with a total of 30000 households connected(94). In the remaining seven regions, the television cable so far remains entirely unused for telecommunication services(95).

(88) On the supply side, broadband cable services are not a substitute for ADSL access services, because the cable distribution network is still extremely fragmented. The network is divided into four hierarchical levels. The lowest level, level-4, comprises the connection between the last relay point in the network and the private household. There are over 100 commercial level-4 operators active in Germany at present, so that an Internet service provider would have to conclude a great number of distribution agreements with these operators in order to achieve a coverage comparable to that of DT's network.

(89) Other innovative technologies, such as the use of electric power networks, are not yet technically or economically mature or reliable enough to be an alternative to DT's local network. The provision of telephone services over existing power lines is still being tested, and is not yet ready to be offered to the public on a commercial basis. Currently only 2000 households in Germany have broadband Internet access over power lines, provided by three different providers(96).

(90) While the situation may change over time, these alternative networks, alone or in combination, cannot at present be regarded as alternatives to DT's copper pair network for the provision of narrowband and broadband telecommunications services to end-users in Germany.

(91) The relevant product or service markets for purposes of this decision, therefore, are the market in local network access for competitors at the wholesale level, and the markets in access to narrowband and broadband connections at the retail level.

(c) RELEVANT GEOGRAPHIC MARKET

(92) The relevant geographic market is the German market, because the local network to which access is sought at wholesale and at retail level extends only over the territory of Germany.

(93) DT's local networks were developed countrywide. Competitors have been given licences by the national authorities, and can be expected to compete on national markets. In those cases where their licences to operate their own networks are restricted to specified parts of Germany, access to DT's local networks is indispensable in order to provide communication with the whole of the country. Access to the local networks is also important to those operators who have not got a network of their own and depend entirely on the incumbent's network.

(94) The bottlenecks in access, local calls and high-speed services do not prevent new competitors from developing local networks in more restricted areas, in densely populated urban areas for example. But as a rule these networks do not enable them to compete on an equal footing across the country with DT.

(95) The geographic market in which competition would take place if there were no bottlenecks is the whole of Germany.

(d) DT'S DOMINANT POSITION

(96) DT holds a dominant position on all the relevant markets, namely the wholesale market in access services for competitors and the retail markets in narrowband and broadband access services for residential and business customers.

(aa) Wholesale access

(97) As regards the provision of wholesale access services, DT is the only German telephone network operator having local networks with countrywide retail coverage. DT grants access to this network to its competitors on a wholesale basis. At present there is no economic alternative to DT's local networks, and it can therefore be accepted that since unbundling began in 1998 DT has had a 100 % share of the market in wholesale access for narrowband and broadband services.

(bb) Narrowband retail access

(98) At the end of 2002 there were about 53,72 million telephone channels in Germany. Of these DT possessed 51,37 million analogue and ISDN channels, while DT's 64 competitors possessed a total of 2,35 million such channels, either in their own networks or on the basis of contracts for unbundled access to the local loop. DT's share of the market in narrowband retail access was therefore 95,6 %. In 2001 its share of this market was 97 %; in 2000 98,3 %; in 1999 99,2 %; and in 1998 99,7 %(97).

(cc) Broadband retail access

(99) The situation on the German market in broadband access services is comparable with that on the narrowband access market. DT has been offering ADSL services (T-DSL) as a mass product only since August 2000, and in October 2002 already had 2580000 customers, whereas its 34 competitors together, including Arcor, QSC and Freenet, had no more than 161000 DSL connections(98). This gives DT a market share of about 94 % of DSL connections(99).

(100) Even if the alternative broadband access technologies are included, DT still has a market share of 90 %. In October 2002, DT had 19000 customers connected by optical fibre, wireless local loop, satellite or leased line, while its competitors had 86000 customers with cable connections(100).

(dd) Potential competition

(101) Given the size of the investment required, the cost to a competitor of building a network reaching as large a proportion of the population as DT's existing local networks is a barrier to entry. The building of a comparable infrastructure is uneconomic using existing technologies, and to extend one over the whole country will remain difficult for the foreseeable future. This prevents competitors from competing with DT on an equal footing, and confines them to building networks of their own covering regional or local markets only. It is highly improbable that the alternative networks taken together will be able to match DT's countrywide local networks and reach a comparable clientele within the foreseeable future.

C. THE ABUSE

(a) MARGIN SQUEEZE

(102) A margin squeeze exists if the charges to be paid to DT for wholesale access, taking monthly charges and one-off charges together, are so expensive that competitors are forced to charge their end-users prices higher than the prices DT charges its own end-users for similar services. If wholesale charges are higher than retail charges, DT's competitors, even if they are at least as efficient as DT, can never make a profit, because on top of the wholesale charges they pay to DT they also have other costs such as marketing, billing, debt collection, etc.

(103) If DT charges its competitors prices for wholesale access to the local loop that are higher than its own prices for retail local network access, it prevents its competitors from offering access via the local loop in addition to call services. If a competitor might be interested in ordering unbundled local loops in order to offer access services to its customers, DT forces it to offset its losses on access services out of higher revenue on telephone calls, as DT itself does. But in recent years call charges have fallen substantially in Germany(101), so that competitors often have no realistic possibility of offsetting one price against another.

(104) DT takes the view that there cannot be abusive pricing in the form of a margin squeeze in the present case, because wholesale charges are imposed by the regulatory authority(102). A margin squeeze, DT contends, must be the result of excessive wholesale prices or insufficient retail prices, or a combination of the two, and it must be legally possible to end the situation by varying either of them. But the wholesale price is fixed by the regulatory authority, so that DT controls only the retail charges, and those are subject to review only for compatibility with the principles of abusive below-cost selling or predation(103).

(105) Contrary to DT's view, however, the margin squeeze is a form of abuse that is relevant to this case. On related markets on which competitors buy wholesale services from the established operator, and depend on the established operator in order to compete on a downstream product or service market, there can very well be a margin squeeze between regulated wholesale and retail prices. To show that there is a margin squeeze it is sufficient that there should be a disproportion between the two charges such that competition is restricted. Of course it has also to be shown that the undertaking subject to price regulation has the commercial discretion to avoid or end the margin squeeze on its own initiative. If it has that discretion, as it has in the present case (see recital 163 et seq.), the question which prices the undertaking can change without the intervention of the State is relevant only for purposes of the choice of remedies to bring the margin squeeze to an end.

(b) METHODOLOGY OF THE MARGIN SQUEEZE TEST

(106) The Commission's practice in previous decisions has been to hold that there is an abuse of a dominant position where the wholesale prices that an integrated dominant undertaking charges for services provided to its competitors on an upstream market and the prices it itself charges end-users on a downstream market are in a proportion such that competition on the wholesale or retail market is restricted(104).

(107) In the case of the local network access at issue here, there is an abusive margin squeeze if the difference between the retail prices charged by a dominant undertaking and the wholesale prices it charges its competitors for comparable services is negative, or insufficient to cover the product-specific costs to the dominant operator of providing its own retail services on the downstream market.

(108) In such a situation, anticompetitive pressure is exerted on competitors' trading margins, which are non-existent or too narrow to enable them to compete with the established operator on retail access markets. An insufficient spread between a vertically integrated dominant operator's wholesale and retail charges constitutes anticompetitive conduct especially where other providers are excluded from competition on the downstream market even if they are at least as efficient as the established operator(105).

(109) In order to establish the existence of a margin squeeze it is essential that the wholesale and retail access services be comparable. The established operator and its competitors as a rule provide retail services of all kinds. It has therefore to be considered whether the established operator's retail and wholesale services are comparable, in the sense that their technical features are the same or at least similar and that they allow the same or at least similar services to be provided(106).

(110) The wholesale charges for unbundled access to local loops can indeed be compared with retail access charges. Wholesale access enables competitors to offer their end-users a range of retail access services (ISDN and ADSL) which goes beyond the basic analogue access.

(111) In order to compare wholesale and retail services, this decision uses a weighted approach to prices and costs. All forms of retail access (analogue, ISDN and ADSL) are aggregated on the basis of the number of each variant that the established operator has marketed to its own end-users (see recitals 112 to 137). The comparable wholesale and retail services are found to be fully unbundled local loop access and retail access in all its variants, i.e. analogue, ISDN and ADSL. If the average retail prices are below the level of the wholesale charges, it can be concluded that there is a margin squeeze. The established operator's product-specific costs for providing its own retail services (see recitals 138 and 139) need to be considered only if the average retail prices are above the level of the wholesale charges. In that case there is a margin squeeze if the product-specific costs exceed the positive spread between the retail prices and the wholesale prices.

(aa) Weighting of retail prices

(112) With full access to DT's local loops, competitors are enabled to offer their end-users on the downstream market a range of different retail services, namely analogue narrowband access, digital narrowband access (ISDN), and broadband access in the form of ADSL services.

(113) In the present case, a single wholesale service (local loop access) has to be compared to a plurality of different retail services (access to analogue, ISDN and ADSL connections). The easiest way to ensure comparability between the different access services at wholesale and retail level is to set a different wholesale charge for each retail service, determining the wholesale charge by subtracting a reasonable margin from the comparable retail charge (the retail-minus approach)(107). Such differentiated wholesale tariffs do not exist in Germany: in setting the monthly charge for local loop rental, the regulatory authority has applied a single wholesale tariff, irrespective of the downstream service the competitor provides over the line.

(114) In the case of fully unbundled local loops, DT rents copper pairs to its competitors for their exclusive use. The competitors have unrestricted control of the customer relationship for the provision of a full range of telecommunications access services over the local loop, including the establishment of ADSL digital connections for high-speed data applications. In such a situation, DT must be considered as imposing an abusive margin squeeze upon its competitors if the charge for full unbundling, allocated as an input cost between the various retail access services which wholesale access makes possible, together with the specific downstream costs, does not allow competitors to offer their own retail access services without suffering a loss.

(115) The tariffs to be taken into account for the comparison of wholesale and retail access services therefore must cover the full range of retail access services which competitors can offer. These tariffs are on the one hand the tariffs for full unbundling of an analogue copper pair (wholesale access service) and on the other the tariffs for a straightforward telephone line, ISDN, and ADSL (retail access service). Extending the comparison of tariffs beyond the straightforward analogue line takes due account of the fact that wholesale access to the local loop allows competitors to offer their customers a range of retail access services wider than the simple analogue subscription.

(116) In order to determine DT's total revenue from retail access services, the individual services have to be weighted. An average price has to be calculated for all retail access services, taking account of the number of each variant of retail access service actually marketed by DT and the respective prices of those lines.

(117) DT contends that it is not right to compare wholesale access charges and retail access charges by this method. The decisive consideration, according to DT, is the point of view of the end-user, and seen from that point of view access to the local network and the calls carried on that network form a single bundle of products. For competitors, access to the local loop is only a necessary prerequisite for the provision of further telecommunications services, and so revenue from those telecommunications services, and especially from telephone calls, must be included in the calculation of DT's revenue on the retail side. DT argues that it takes account of this aspect by offsetting revenues to arrive at its retail charges. In DT's view the wholesale costs for the local loop are overheads both for the provision of retail access and for telephone calls, so that any attempt to allocate costs to individual services in order to investigate the possibility of below-cost selling makes no economic sense and is consequently arbitrary(108).

(118) DT further contends that the comparison between the two charges is incomplete, because the calculation of the average retail price takes no account of the optional tariffs and DT's various ISDN tariff variants(109). Lastly, the margin squeeze test applied by the Commission groups all regions and categories of customer together, which renders it unsuitable for assessing the overall scope for market entry by competitors(110).

(119) Contrary to the view taken by DT, however, revenue from telephone calls should not be included in the calculation of the margin squeeze. This is clear both from the requirements imposed by the Community directives and from economic considerations.

(120) Separate consideration of access charges and call charges is in fact required by the Community-law principle of tariff rebalancing. For purposes of cost-oriented pricing, access to local network lines and the offer of different categories of call are clearly separate services.

(121) Article 4c(3) of Directive 90/388/EEC on competition in the markets for telecommunications services, as amended by Directive 96/19/EC (see recital 71) with regard to the implementation of full competition in telecommunications markets, states that: "Member States shall allow their telecommunications organisations to re-balance tariffs taking account of specific market conditions and of the need to ensure the affordability of a universal service, and, in particular, Member States shall allow them to adapt current rates which are not in line with costs and which increase the burden of universal service provision, in order to achieve tariffs based on real costs."

(122) The reasoning behind this provision is explained in recital 20 to Directive 96/19/EC. It says: "As regards the cost structure of voice telephony, a distinction must be made between the initial connection, the monthly rental, local calls, regional calls and long distance calls. The tariff structure of voice telephony provided by the telecommunications organisations in certain Member States is currently still out of line with cost. Certain categories of calls are provided at a loss and are cross-subsidised out of the profits from other categories. Artificially low prices, however, impede competition since potential competitors have no incentive to enter into the relevant segment of the voice telephony market ... Member States should phase out as rapidly as possible all unjustified restrictions on tariff rebalancing by the telecommunications organisations."

(123) The concept of tariff rebalancing was clarified by the Commission in its Decisions on requests by Ireland(111), Portugal(112), Luxembourg(113), Spain(114) and Greece(115) for additional time to implement the Directives. The Commission said therein: "cost orientation of tariffs means as a general rule that prices are adjusted such that revenues are rebalanced with costs, i.e.:

- connection and rental revenues cover fixed costs (plus a standard margin),

- local call revenues cover local call costs (plus a standard margin),

- trunk call revenues cover trunk calls (plus a standard margin),

- international call revenues cover international call costs (plus a standard margin).

Consequently telecommunications organisations must raise bi-monthly rental and local calls (or at least not decrease these charges) and reduce tariffs for long distance calls."

(124) Article 17(2) of Directive 98/10/EC of the European Parliament and the Council of 26 February 1998 on the application of open network provision (ONP) to voice telephony and on universal service for telecommunications in a competitive environment(116) states: "Tariffs for use of the fixed public telephone network and fixed public telephone services shall follow the basic principles of cost orientation set out in Annex II to Directive 90/387/EEC."

(125) Annex II to Directive 90/387/EEC of the Council of 28 June 1990 on the establishment of the internal market for telecommunications services through the implementation of open network provision(117), as amended by Directive 97/51/EC(118), states: "tariffs must be based on objective criteria and, until such time as competition becomes effective in keeping down prices for users, must in principle be cost oriented, on the understanding that the fixing of the actual tariff level will continue to be the province of national legislation and is not the subject of open network provision conditions ... in order to leave users a choice between the individual service elements and where technology so permits, tariffs must be sufficiently unbundled in accordance with the competition rules of the Treaty. In particular, additional features introduced to provide certain specific extra services must, as a general rule, be charged independently of the inclusive features and transportation as such ... tariffs must be non-discriminatory and guarantee equality of treatment, except for restrictions which are compatible with Community law. Any charge for access to network resources or services must comply with the principles set out above and with the competition rules of the Treaty and must also take into account the principle of fair-sharing in the global cost of the resources used, the need for a reasonable level of return on investment and, where appropriate, the financing of universal service in accordance with the interconnection Directive."

(126) But on economic grounds too it is reasonable and legitimate to apply the margin squeeze test by looking at DT's revenue from access charges in isolation, and to exclude revenue from call traffic. When the margin squeeze test is applied to the case, the question is not how costs should be allocated in order to establish whether or not the costs of an individual service are being covered; if that were the objective, the revenue from call charges might indeed be relevant. The margin squeeze test seeks to compare charges for two particular services at different commercial levels. The comparison would be distorted if revenue from call traffic were to be included, because call services, which are additional to access services, cannot also be included in the calculation on the wholesale side. The question of cost allocation and cost cover will become relevant only at a second stage, if it is found that there is a positive margin between retail prices and wholesale prices. But there too a comparison between the two levels can be made without including telephone calls, provided both the spread between charges and the product-specific costs are treated the same way.

(127) The method used to determine whether there is a margin squeeze in this case is based on the principle that the established operator's tariff structure must enable competitors to compete with that operator effectively, and at least to replicate the established operator's customer pattern. It must not be assumed that the competitors' customer structure and range of services will necessarily be more profitable than those of the incumbent. The primary consideration here is the effect on market entry by competitors, and not the question whether the end-user regards access services and calls as a single bundle of products

(128) Thus DT cannot invoke a calculation offsetting access and call charges against one another in order to challenge the admissibility of the comparison method. It cannot be assumed that all competitors have the same revenue structure as the established operator, and thus the same scope for offsetting one source of revenue against another. Nor should revenue from interconnection (for call termination, for example) be included in the calculation of the margin squeeze, because in accordance with Directive 97/33/EC on interconnection(119) it is required to be cost-oriented, so that with the exception of the permissible return on capital it has only an insignificant impact on the net revenue of the local access network operator.

(129) There is still a revenue shortfall on connections in Germany, and the use of call charges to finance that shortfall has been facilitated by the fact that competition in the local network continues to be very limited. For that reason the regulatory authority takes the view that more cost-oriented pricing is needed at the local level, and can be expected to result from the introduction of carrier selection and carrier preselection for local calls(120). Similarly, DT itself, applying for authorisation of charges on 31 October 2002, invoked the organisational necessity of further rebalancing of access and call charges in order to justify the increase in the basic charge it was applying for(121).

(130) Contrary to the view taken by DT, the higher monthly retail charges applying under the optional tariffs should not be included in the calculation of the margin squeeze either, even if the optional tariffs are increasingly being requested by DT's private customers too(122). An increase of this kind in the monthly charges does not reflect any increased value of the line connected, which might be the case if there were technical improvements, for example, or if more sophisticated services were made available. The options tariffs are merely a method by which DT offers its end-users the possibility of paying a higher monthly charge in order to enjoy lower call charges(123).

(131) The optional tariffs represent a bundled offer of access and call services. But for competitors wishing to enter the market in retail access, the decisive consideration is the margin left them between the wholesale and retail charges applied under DT's standard tariffs. The increased access charges in DT's optional tariffs are a component in a contractual formula that offsets access charges and call charges; they cannot be calculated separately. Given their more limited financial resources, competitors are not usually able to do the same thing. This also makes it impossible to allocate costs to the individual components in the service offered, which is why the regulatory authority decided with effect from 1 January 2002 to take the optional tariffs out of the price cap mechanism and in future to regulate them by individual authorisation(124).

(132) DT also argues that the margin squeeze test is incorrect because it includes all regions and categories of customer alike, without further differentiation(125); this argument too must be rejected. The approach taken is in line with the principle that there should be equal and effective competition throughout the country(126). It cannot be supposed that all of DT's competitors compete with the established operator only in a defined region, and want to deal only with customers in the most attractive market segment, in big cities or urban areas for example. Some competitors, such as Arcor, do intend to compete with DT on a countrywide basis, but have so far been considerably hindered in their efforts to do so by the pricing policy applied by DT. And no distinction is made here between residential and business customers, either at wholesale or retail level, because no sufficiently precise demarcation between them is possible.

(133) DT argues that its competitors are not interested in connecting and serving analogue customers, but instead target only ISDN and ADSL users(127); this argument too must be rejected, especially if it can be shown that there would be a margin squeeze even on the supposition that the competitors were using every unbundled customer line for the highest-value services, such as ADSL services provided over ISDN lines. On that assumption there was in fact always a margin squeeze under DT's local network access tariff structure from the entry into force of the unbundling obligation in Germany at the beginning of 1998 at least until the tariff changes on 1 May 2002(128).

(134) Competitors have aimed to win over subscribers on the basis of their specific needs, and to offer them services of all kinds. Digital broadband may indeed be the most profitable, or at least the most promising, of the markets to which access is being offered via the local loop, but it is not the only market competitors would like to enter. Apart from a few operators who have specialised from the outset in DSL services to frequent users and business customers, most competitors have tried to gain customers not only for digital broadband connections, but for analogue and ISDN connections too(129).

(135) In adopting this business strategy, since 1998, when unbundling was made mandatory, the competitors' main objective has been to enter the mass market of telephone customers with analogue lines. In 1998, the great majority of subscribers in Germany were still connected by analogue lines. Digital ISDN lines accounted for only a small percentage, and ADSL-upgraded lines started to be offered commercially only in July 1999. In April 2001 analogue lines still accounted for 75 % of all lines in Germany, and the competitors had a share of only 0,5 % of that market(130).

(136) The reason competitors did not enter the market in greater numbers is that many were deterred by the high wholesale access charges. Even when digital services started to be rolled out more broadly, competitors continued to be interested in analogue lines: they were attracted by the prospect of being able to equip their own customers, over time, with higher-value lines and services(131). In addition, until the European requirements with regard to carrier selection and carrier preselection have finally been implemented in practice in the local network in Germany, operators continue to offer local calls to their own subscribers only.

(137) DT's wholesale tariffs are the same for all varieties of subscriber line, so that it is not necessary to calculate a weighted average wholesale price. For the calculation of the spread by reference to retail prices, these wholesale prices constitute DT's revenues.

(bb) Product-specific costs

(138) The spread between the historic operator's retail and wholesale tariffs can be negative, positive or zero. If the wholesale charges are higher than the retail charges there is a negative spread; in that case there is a margin squeeze in any event, irrespective of the product-specific costs. If the wholesale charges are lower than the retail charges there is a positive spread; in that case there is a price squeeze if the spread is not sufficient to enable the historic operator to cover the product-specific costs of providing its services to end-users.

(139) The point of departure for determining DT's product-specific costs is the total cost of providing end-user access. But the total cost includes a network cost component, for such things as the copper cable, which is not to be taken into account in the calculation. The product-specific costs comprise only the costs of providing those additional services which are needed to give DT's end-users access to T-Net and T-ISDN connections (with or without T-DSL), including billing, customer care, etc.

(c) EXTEND OF THE MARGIN SQUEEZE

(140) Where wholesale and retail services are comparable, as described above, a margin squeeze occurs if the spread between DT's retail and wholesale prices is either negative or at least insufficient to cover DT's own downstream costs. This would mean that DT would have been unable to offer its own retail services without incurring a loss if, during the period under investigation, i.e. since 1998, it had had to pay the wholesale access price as an internal transfer price for its own retail operations.

(141) As a consequence the profit margins of competitors are squeezed, even if they are just as efficient as DT. This means that they cannot offer retail access services at a competitive price unless they find additional efficiency gains. A margin squeeze imposes on competitors additional efficiency constraints which the incumbent does not have to support in providing its own retail services.

(aa) Calculation of the average retail price for local network access

(142) DT's average retail price at the end of each year since the unbundling of local loops began must be calculated on the basis of the number of lines marketed by DT to its end-users in that year (see recitals 27 and 28) and the corresponding retail prices (see recital 31 et seq.). These average prices are composed of two items, the monthly subscription charge and the one-off charge for a new connection, a takeover or a discontinuance.

(143) On 31 December 2002, DT had a total of [...] end-user lines, of which [...] were analogue lines (T-Net) provided at a monthly charge of EUR 11,49 and [...] were ISDN lines provided at a monthly charge of between EUR 19,56 and EUR 28,12. These figures include 3100000 DT lines equipped with ADSL, of which [...] were provided over T-Net at a monthly charge of EUR 28,72 and [...] were provided over T-ISDN multi-device mode (standard and comfort) at a monthly charge of EUR 31,54 or EUR 33,75(132).

(144) As can be seen from the calculations below, at the end of 2002 the average retail price for all services provided by DT over local loops came to EUR 15,17 per month and per line.

Table 3

>TABLE>

(145) Using the same model, the average monthly retail prices at the end of 2001, 2000, 1999 and 1998 can be calculated as follows:

Table 4

>TABLE>

Table 5

>TABLE>

Table 6

>TABLE>

Table 7

>TABLE>

(146) In addition to the monthly fees, DT also charges its customers a one-off fee for taking over an existing line or opening a new one. From 1998 to the present, the one-off charge for taking over a serviceable T-Net or T-ISDN connection has been EUR 22,22 and the charge for provision of a serviceable connection EUR 44,45. New connections are more frequent than takeovers ([...] % of cases compared with [...] %)(133). The average one-off charge to end-users for T-Net and T-ISDN therefore comes EUR [...](134).

(147) When the market was opened up to competition in 2000, DT initially charged a one-off fee of EUR 44,45 for providing T-DSL. It then raised this charge to EUR 64,61 from 1 July 2002 and to EUR 86,16 from 1 January 2003. So the average one-off charge for all DT end-user lines was EUR [...] from 1 July 2002 and EUR [...] from 1 January 2003(135).

(148) Assuming that the average end-user keeps the same telephone subscription for a period of [...] months, allowing in particular for changes of residence(136), these average one-off charges should be divided by [...]. The result must then be added to the monthly charge in order to obtain an average monthly retail price for access to the local network. Using this method, DT's average total retail prices are as follows:

Table 8

>TABLE>

(bb) Calculation of the wholesale price for local network access

(149) Like the retail price, DT's wholesale price for local loop access is also composed of two items - the monthly rental charge payable periodically and the one-off charge for opening a new connection or taking over or discontinuing an existing connection.

(150) From 1 April 2001 the monthly charge for DT's competitors was EUR 12,48 and it has been reduced to EUR 11,80 as of 1 May 2003. From 1 April 2001, the one-off charges were EUR 92,59 for a straightforward takeover, EUR 86,51 for a straightforward new connection and EUR 38,06 or EUR 59,24 for discontinuing a connection with or without transferring the customer. Since 1 April 2002 the one-off charges have been in the first place EUR 70,56 for a straightforward takeover, EUR 81,12 for a straightforward new connection and EUR 34,94 or EUR 50,71 for discontinuance with or without transfer(137).

(151) The discontinuance charge is payable for re-connecting an unbundled line to DT's network and is imposed only on competitors at wholesale level(138). The discontinuance charge and the charge for access provision are the only one-off wholesale charges which competitors must pay to DT. In practice, takeovers of lines that are still activated are more frequent than the reopening of deactivated lines(139). This can be used to work out the average one-off wholesale price charged to competitors. As with the one-off retail prices (see recital 148), these average total one-off charges must be divided by [...] and the result added to the monthly charge in order to calculate DT's average prices for providing its competitors with wholesale access services. DT's total wholesale prices calculated in this manner are set out below.

Table 9

>TABLE>

(cc) Spread between retail and wholesale prices

(152) As can be seen from the calculations below, the spread between DT's average retail access price and its average wholesale access price was always negative from the time when local loop unbundling became a legal obligation in Germany in 1998 up to the end of 2001.

Table 10

>TABLE>

(153) Since the spread between DT's retail and wholesale prices was always negative between 1998 and 2001, there is not even any need, for the purposes of proving the existence of a margin squeeze over that period, to determine whether this spread was sufficient to cover DT's downstream costs for customer relations. These negative spreads per month and per line are a direct measure of the margin squeeze between the beginning of 1998 and the end of 2001.

(154) After DT had increased certain monthly and one-off charges in 2002 (see recitals 44, 50 and 51), there was a positive spread between its retail and wholesale prices, which amounted to EUR [...] per month and per line at 31 December 2002 or 1 January 2003 and rose to EUR [...] on 1 February 2003 as a result of the EUR 0,33 increase in monthly charges for T-Net connections approved by the regulatory authority on 19 December 2002. Consequently, in order to prove that a margin squeeze exists for 2002 and at the present time, DT's product-specific costs must be determined in order to assess whether this positive spread is sufficient to cover DT's product-specific costs for providing retail services.

(dd) Product-specific costs

(155) To determine DT's product-specific costs for providing retail access to the local network, it is necessary to deduct the overheads, i.e. the cost of merely providing the network infrastructure, from the total costs. Product-specific costs would arise from any special equipment required to provide analogue, ISDN and ASDL services and from DT's customer relations.

(156) No extra equipment is needed to provide local network access for end-users over analogue lines, so that here the product-specific costs derive simply from the customer relations services such as marketing, maintenance and invoicing. However, specific equipment is required to provide simple local network access over digital narrowband lines (ISDN), generating separate costs. Here too there are product-specific costs arising out of customer relations.

(157) Extra equipment is also needed to provide ADSL services, pushing up further the product-specific costs. The most important cost factors for ADSL services include technical devices at both ends of the copper pair (i.e. a modem and a splitter at the consumer's premises and at the local exchange), multiplexing equipment located at the exchange to manage the data streams from several hundreds of ADSL connections, known as a digital subscriber line access multiplexer (DSLAM), and a broadband access server (BAS) located upstream in the network, to organise the traffic generated by several DSLAMs and sent into a backhaul transmission network, so as to manage the IP layer of the service.

(158) According to DT, the total monthly cost of retail services per analogue line comes to EUR [...](140), the monthly retail cost per ISDN line comes to EUR [...](141) and the monthly retail cost per ADSL line comes to EUR [...](142). These amounts may however include components of network costs (i.e. the cost of the copper pair) and product-specific costs (other service-specific costs of connecting up to the final customer) and should therefore be broken down further in order to determine DT's product-specific costs for providing retail access to its local loop network.

(159) It can be concluded from DT's data for 2001 that the monthly product-specific costs for providing lines are EUR [...] per analogue line(143), EUR [...] per ISDN line(144) and EUR [...] per ADSL connection(145). These costs produce a weighted average product-specific cost of EUR [...] per line, as shown in the calculation set out below:

Table 11

>TABLE>

(ee) Result

(160) The average cost calculation shows that, even after DT's price increases in May and July 2002 and January and February 2003, the margin squeeze still exists, as the product-specific costs still exceed the positive spread between retail and wholesale prices(146). Moreover, DT's average product-specific costs rise considerably with each new T-DSL customer it gains. The size of the margin squeeze after DT's latest price adjustments is shown below:

Table 12

>TABLE>

(161) These calculations show that a margin squeeze still exists in access to the local network, even though it may be decreasing slightly over time. To prove that DT is abusing its dominant position, the margin squeeze affecting competitors under the present tariff structure can be quantified - using a weighted approach - at EUR [...] per line and per month (see recitals 111 and 112). Although DT's price changes in 2002 produced a positive spread between the average retail and wholesale prices, under the calculation method used in this Decision, this spread has hitherto been insufficient to cover DT's product-specific costs for providing retail services.

(162) DT argues that, leaving aside analogue access, no margin squeeze has been applied either in the past or in the present in the higher-value variants of local access(147). However, to examine individual local loop variants on their own would from the outset be inconsistent with the approach followed here, which is to look at average retail access prices in relation to wholesale prices, thereby obtaining a picture of DT's customer structure (see recital 112 et seq.). But even if every unbundled line were to be used by competitors for the highest-value retail service (DSL over ISDN connections), there would still have been a margin squeeze up to 30 April 2002(148). The weighted approach is therefore more advantageous to DT than its own.

(d) SCOPE FOR AVOIDING THE MARGIN SQUEEZE

(163) The facts and figures set out in this decision prove that since 1 January 1998 DT could have avoided the margin squeeze in access to the local network, for example by increasing the existing retail charges for analogue, ISDN and ADSL connections. The fact that such scope does exist is evidenced by the retail price increases so far introduced by DT since the local loop in Germany was unbundled and by reductions in wholesale charges. These are steps in the right direction, but insufficient in volume to rectify the unfair pricing abuse.

(aa) Price cap periods 1998/99 and 2000/01

(164) During the first two price cap periods DT could have avoided the margin squeeze by increasing retail charges for analogue and ISDN connections, because it was entitled to apply to the regulatory authority at any time asking for adjustments to charges (see recital 36). By reducing call charges it could secure an increase in access charges within baskets of services for residential and business customers, provided that the average basket price did not exceed the prescribed price cap index.

(165) The price cap system set up by the Federal Ministry of Posts and Telecommunications and the regulatory authority thus gave DT sufficient scope, during the period between 1998 and 2001, to restructure entirely its tariff system on the basis of the specific costs of the individual services forming part of the baskets. Increases in retail access charges could be offset within the price cap system by reducing call charges within the baskets for residential and business customers. The original price cap system laid down no limits on reductions in tariffs for individual services, so that DT was free to reduce certain individual charges while increasing others by a corresponding amount and hence complying with its obligations for the basket in question. As a lower limit on reductions in call charges, the regulatory authority merely applied the rule that such charges must always be at least 25 % higher than the respective interconnection charges. Accordingly, each time DT submitted applications for the approval of adjustments to charges under the price cap system, the regulatory authority made only a rough assessment to check that the applicable index figures were respected and that the proposed charges did not manifestly breach the requirements of the Telecommunications Act. In the majority of all six tariff adjustment applications between 1998 and 2001 this was the case(149).

(166) During the first price cap period from 1 January 1998 to 31 December 1999, DT reduced the tariffs for calls by more than 20 %, i.e. by much more than the 4,3 % mandatory reduction(150). This meant that, after only a short time, the tariffs lay well below the mandatory levels. Since then DT has further reduced call charges. All in all, the regulatory authority approved six applications for reductions in call charges between January 1998 and February 2000(151). The considerable drop in call charges undertaken by DT between 1998 and 2000 meant that an increase in its monthly and/or one-off charges for retail access was not only economically feasible but, in view of the margin squeeze, a legal requirement, provided that there was no breach of the price cap provisions in force.

(167) More specifically, during the first price cap period between 1 January 1998 and 31 December 1999, DT released turnover of EUR [...] million over and above the mandatory 4,3 % price reduction. During the second price cap period between 1 January 2000 and 31 December 2001, the volume of turnover released, after taking away the reduction laid down by the price cap system, came to an additional EUR [...]. If these amounts had been redirected to connections for residential and business customers, they could have been used entirely to increase retail access charges - either the monthly or the one-off charges(152).

(168) Furthermore, these amounts should merely be regarded as a minimum, as DT was very much in a position to undertake further reductions in call charges at any time within the baskets of services for residential and business customers, in particular tariffs for local calls, and thereby to obtain more leeway for price increases in the monthly and one-off charges for analogue and ISDN connections. The wholesale prices for interconnection between fixed networks, which in accordance with Article 7(2) of Directive 97/33/EC must be cost-oriented, can be used as an indication of the cost of individual telephone calls. However, even after the reduction in tariffs in May 2002, all DT's retail call charges remained considerably higher than the corresponding interconnection charges, indeed up to 570 % higher, depending on the type of call(153). This margin provided scope for DT to end the margin squeeze between access charges at wholesale and retail level through more cost-oriented pricing of the services included in the baskets.

(169) DT argues that under the price cap mechanism all retail charges are fixed by law and no deviations from the approved charges are admissible(154). However, this argument overlooks the two-tier system for approving charges under the price cap mechanism (see recital 36). It is certainly true that the regulatory authority also investigates and approves adjustments to charges undertaken within the price cap to ensure they comply with the mandatory index figures(155). However, there is nothing to prevent DT exerting a constant influence on retail charges by submitting further applications for adjustments to charges, provided that these adjustments stay within the price cap. Indeed DT has explicitly recognised that within the price cap system it enjoys legal scope to restructure further its charges for local network access on the basis of the relevant specific costs(156).

(170) DT also concedes that it took steps in that direction, applying "soft" restructuring measures in the form of optional tariffs with higher access charges and lower call charges(157). However, these are not to be taken into consideration in this Decision (see recital 130 and 131). DT undertook no such price increases in standard access tariffs, which are
