Annual report 2012

Fixed access network

The Group achieved all key indicators relating to the management of access devices for fixed services, transmission systems, electromechanical devices and real estate used for technological purposes. Service availability indicators due to the Group’s impact, the number of incidents and duration, and the consumption of electricity were within planned target values. We also successfully controlled costs, which were within planned values in all segments.

The trend of a falling number of PSTN and ISDN connections continued, while growth in broadband services, VoIP telephony and fibre optic FTTH services likewise continued.

Telekom Slovenije conducted a study regarding the achievement of Digital Agenda 2020 objectives. The latter envisages broadband connections to all household in Europe by 2020, accompanied by the resulting economic growth. A detailed analysis of the existing network, technological capacities and possible upgrades serves as the basis for the drafting of a plan that meets all criteria set out in the aforementioned project.

The study proposes the upgrading of the existing network with the less expensive combination of a shortened copper loop (FTTH+VDSL2), fibre optic FTTH networks and the construction of open base stations. Due to the co-use of the existing infrastructure, such solutions are more economical than the construction of completely new fibre optic networks, while the usefulness of the above mentioned network is significantly better. Past experience indicates that bringing the capacity of fibre optic networks close to that of existing, previously built networks can only be achieved with difficulty. The general and professional publics, and representatives of regulatory bodies, the competent government authorities and EU bodies were briefed on the results of the study.

Due to the disconnection or migration of subscribers, the Group continued to optimise connections during the replacement of time division multiplexes (TDM) and TDM DSLAMs. The entire migration of subscribers from TDM DSLAMs to IP DSLAMs was carried out at the end of the year. Savings from the entire optimisation process cover the procurement of back-up units and premises, and the reduction in electricity consumption for power supply and air conditioning units.

Transmission systems

The Group successfully integrated the mobile and fixed sections of the SDH network in joint control and thus reduced operating costs associated with maintenance and management. Flow units are duplicated at key and critical elements of the core network, thus reducing the risk associated with failures. While building the DWDM network, we increased the capacity of the Ljubljana and Maribor Tabor nodes by building in expansion modules, and built the Maribor Tezno node. The Group built a new DWDM system along the Maribor Tezno - Ljubljana - Bled - Nova Gorica - Koper route for the needs of international and national connections. We replaced old SDH elements with newer, more cost and energy efficient elements at 16 locations on the access segment of transmission systems.

Electrical equipment and environmental protection

The Group continued to replace air conditioning units and reconstruct electricity systems in line with planned investments. By doing so, we implemented measures to reduce electricity consumption, which was 3% lower at Telekom Slovenije than the previous year, despite the inclusion of new users (TV studio Stegne and data centres). Completed among major investments was the first phase of the reconstruction of the air conditioning system at a facility in Maribor and the replacement of the transformer station at the Stegne location, which facilitates the smooth functioning of the TV studio.

The Group continued to refurbish worn out electrical installations and set up lightning conductors. We thus improved safety and functional reliability, and complied with legal requirements. No irregularities were identified with regard to the management of greenhouse and fluorinated gases during a visit by an inspector for the environment and spatial planning. During a visit in 2011, an inspector imposed a mandatory fine due to the inappropriate registration of air conditioning devices with the Slovenian Environmental Agency in 2010.

Regular maintenance ensures the reliable functioning of devices. There were no major disruptions to telecommunications traffic due to disruption to the electricity supply or the air conditioning system, despite problems in electricity distribution networks. The proportion of work carried out internally with respect to maintaining energy systems and the fulfilment of legal obligations is increasing. This is reflected in a decrease in expenditure for external service providers of more than 30% relative to 2010, although the scope of built-in equipment has risen.

Technical inspections of eight of the most energy demanding buildings are in their final phase. The project to obtain ISO 50001 energy management certification continues with the implementation of energy guidelines to reduce the environmental burden and lower costs.

Electromagnetic radiation

The Groups complies in full with requirements regarding the strength of electromagnetic radiation. Slovenian requirements are even stricter than those of the EU in some respects. In January 2012, the Group submitted 74 sets of comprehensive base station measurement documentation, and an additional 109 by the end of the year. With the next submission in 2013, the total number of sets of base station measurement documentation will exceed 1,000. Documentation was drafted by authorised institutions and is accessible in full to all interested local communities. Many of those communities have already been briefed on the aforementioned information (e.g. Jesenice, Kamnik, Škofja Loka and Velike Lašče).
