2 First Digital components under the First Telecommunications Project: Satellite and Microwave transmission systems TAE backbone and other FO cable systems First TDM Digital Switching systems (80 ths. lines 100 digital nodes) Distributed around country DVB-IP TV terminals network Key features of Current KT s Microwave Network: Quite deeply penetrated network, reaching outlaying mountainous areas Wide range of transmission structures used: SDH STM-1, STM-4, PDH and various hybrid TDM-IP solutions like FibeAir IP10, IP20 etc. Microwave link capacities from 34Mbps to nx1gbps mainly achieved thru spacefrequency diversity principles Project positive effects of CDMA-450 project for the outlaying areas: Lots of villages 2-90 (avg. 40) km distant from regional centers are served by CDMA base stations more then 85% of populated territories covered 100 base stations all around the country in addition to other networks will make the total access network capacity up to 1,5 million voice ports Technical Components under the Digital Horizon Telecommunication Project: A distributed dual-homed SoftX3000 softswitch system Transport network mostly a 10G packet backbone Newly put in operation 470 ths. ASLs and up to 80 ths. ADSL2+ Number of AN nodes - 300, an av. last mile length 0.5 to 1 km Total network capacity (analogue, TDM and MSAN inclusively) ths. of narrowband ports and about 100 thousand broadband ports

5 Active technical reequipment in the Access and Services Planes may open new breakthrough business directions: Unified IMS-based Services Core with FMC elements Entering mobile network market: the radio access network will be mainly built on a Single RAN approach and to serve wireless user terminals of technologies like CDMA, UMTS 2,5G/3G, LTE; Wide spread deployment of broadband based on MetroEthernet, GPON and radio access technologies like Wi-Fi and LTE-advanced especially with an accent on short-wave Femto-cells for Fixed Services in residential sector; Moving MSAN based access infrastructure to regions with lower service demand; Expansion of the voice services subscriber base mostly at the expense of SIPtelephony whipping up mobile segment Wi-Fi based terminal users; Using a single infrastructure based on IP. Now migrating from 1/10GE (//STM- 16) to 100GE/WDM systems
