Conclusion © 2007 2 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.

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. y NTT already provides an IP phone service “Hikari Phone” using the ordinary telephone numbering plan.

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 Number ofsubscribers(millions) 1.4 7 1.2 6 1.0 5 ADSL 0.8 4 0.6 3 0.4 2 FTTH 0.2 1 0 0 Net increase in numbers (millions) -0.2 Q2 Q3 Q4 Q1 Q2 Q3 Q4 Q1 Q2 Q3 Q4 Q1 Q2 Q3 Q4 Q1 Q2 Q3 2002 2003 2004 2005 2006 Source: Website of the Ministry of Internal Affairs and Communications © 2007 5 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. 9.2 Fix-line-based operators （billion 8.8 -2.7 NTT East/West/Communications +0.4 US$） 6.5 6.9 ProfitProfit Profit +0.4 2.8 +530 2.6 1.8 2.0 （billion Mobile (NTT DoCoMo) +1.0 -0.2 -0.6 US$） 55 50.6 RevenueRevenue RevenueRevenue 49.4 48.0 50 47.2 45 42.1 40.1 40.4 39.7 40 35 2002 2003 2004 2005 2002 2003 2004 2005 © 2007 6 Hokkaido rticularly fierce in urban areas Aomori Akita Iwate Miyagi 7 Yamagata TT faces tough competition and is falling Fukushima Ibaraki Tochigi Gunma Saitama Chiba Tokyo Kanagawa Yamanashi © 2007 Nigata Toyama Ishikawa Gifu Nagano Shizuoka Aichi Fukui Mie Nara Kyoto Osaka Shiga Competition for share of FTTH (Asis paof March 2005) Wakayama Hyogo •NTT has over 50% shareFTTH in optical market accessin individual nationwide. prefectures However, in urban areas, Okayama where fibers can be installed efficiently, N Hiroshima behind in many prefectures.
