3 Measures taken to prolong the lifetime of NTT s PSTN facilities NTT s PSTN consists of several thousand switches. Although a then-state-of-art switching system (NS8000) was developed around 10 years ago, the rapid progress in technology since then has resulted in the discontinuation of production of some components used in the system. Currently, we are trying to prolong the lifetime of the switches by re-establishing sources for such components.

4 Maturing of IP telephony technology in Japan IP telephony is spreading from business users (IP-PBX). Low rates (or free between specific points) offered by ISPs have increased the number of IP phone users in Japan to more than 13 million. NTT already provides an IP phone service Hikari Phone using the ordinary telephone numbering plan. *1 1 Free OCN 2 Free 3 7 / 3min Affiliated ISP s IP network 7 / 3 min 9 / 3 min 14 / min Int l phone network Discount rate OCN.Phone Affiliated ISP s IP phone (178ISPs) *2 Non-affiliated ISP s IP phone (12ISPs) *2 *2 PSTN phone PSTN phone Mobile phone Int l phone Number of subscribers (millions) Increase of subscribers to IP phone service Remarkable growth *1: NTT Communications, Inc.: *2: not changed by distance 4

5 Change in net increase of subscribers to broadband service In the first quarter of 2005, the net increase in FTTH users exceeded that of ADSL users. In the second quarter of 2006, the number of ADSL users began to decrease. In contrast, as anticipated by the u-japan Plan, optical access is increasing rapidly. 1.6 Net increase in numbers (millions) ADSL Q2 Q3 Q4 Q FTTH Q2 Q3 Q4 Q Q2 Q3 Q4 Q1 Q3 Q4 Q1 Q Q Q Number of subscribers (millions) Source: Website of the Ministry of Internal Affairs and Communications 5

6 Decrease in revenues from both fixed-line and mobile phone services of NTT The revenue from the fixed-line phone service has decreased considerably. The revenue from the mobile phone service has also begun to decrease. Fix-line-based operators NTT East/West/Communications Profit Profit (billion US$) (billion US$) Mobile (NTT DoCoMo) Revenue Revenue Revenue Revenue Profit

7 Competition for share of FTTH is particularly fierce in urban areas NTT has over 50% share in optical access nationwide. However, in urban areas, where fibers can be installed efficiently, NTT faces tough competition and is falling behind in many prefectures. Share of FTTH market in individual prefectures (As of March 2005) NTT s share (%) NTT average Toyama Ishikawa Nagano Tokyo Kanagawa Ibaraki Tochigi Gunma Saitama Chiba Akita Hokkaido Mie Nara Aichi Gifu Ehime Tottori Fukuoka Saga Nagasaki Hiroshima Shimane Shiga Kyoto Fukui Oita Miyazaki Kumamoto Kagoshima Yamaguchi Kagawa Tokushima Kochi Osaka Wakayama Hyogo Okayama Shizuoka Yamanashi Nigata Iwate Miyagi Yamagata Fukushima Aomori Okinawa 7

9 Future direction of NTT as a telecom carrier It is urgent for NTT to increase profit by increasing revenue in addition to reducing capital and operational expenditure. Promote broadband & ubiquitous services like FMC and triple play >Revenue shift from telephony Revenue from telephony Cost Revenue from Broadband and ubiquitous services Establish service delivery platform for new seamless businesses >Expand telecom market Migrate telephone network to IP >Reduce capital and operational expenditure 9

10 Key technology for revenue shift (GE-PON) 10

11 Triple play on a single fiber - already commercially available - Broadcasting companies Broadcast VOD Internet I S P Telephone network Broadcast Programs Videos High-speed Internet IP phone IP network Optical fiber : Simultaneous transmission of broadcast programs and IP data IP phone : High-quality videophone Telephone TV : High-quality broadcast and video distribution TV PC Internet : Stable and high throughput environment 11

12 Features of NTT s GE-PON system - Fine-tuned bandwidth control for each user A peak speed of 100M bps bidirectional transmission for each customer is possible under low traffic loads, with IEEE 802.3ah interface conditions. In the event of heavy traffic, the operator can control the minimum bandwidth allocated to each ONU (this enhances the functionality of IEEE 802.3ah). For example, if if 32 users share the bandwidth equally, the operator can guarantee at least 30M bps for each customer.

14 Approach to NGN Build NGN that is of high quality, flexible and secure Develop and spread broadband and ubiquitous services that allow fixedmobile convergence (FMC) Open network that allows collaboration with other carriers and xsps Smooth migration from existing fixed-line to IP telephony, and from copper to optical access Expand business opportunities by exploiting broadband and ubiquitous services xsp: Provide new business opportunities Strengthen competitive edge and financial base, and contribute to achievement of u-japan 14

15 Basic concept of NTT s NGN Lifestyle support, home appliance IP-based network enabling provision of seamless fixed and mobile services Community, e-commerce Broadcast, content providers IMS ASPs and various service players Open network interface NGN Network interface disclosure, to enable various service players to provide a wide array of applications on the NGN Home network Safe, secure, and convenient network equipped with features of both the existing fixed-line telephone and IP networks Office, hotspot, etc. IMS: IP Multimedia Subsystem 15
