Although a then-state-of-art switching system 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.

This fall has not yet been made up for by revenue from broadband businesses. It is necessary to change the revenue structure by expanding revenue from Broadband services provided on the NGN.

ProposedProposed statusstatus ofof broadbandbroadband networksnetworks inin 20102010 Proposed on Aug. 11, 2006 1. 100% broadband network The projected status of a 100% broadband network, through which broadband services are made available to all communities, is as follows: (1) Overall, a variety of wireline and wireless technologies will be seamlessly linked, and broadband service based on one or more of these technologies will be available nationwide. (2) In areas where cost-effective investment is difficult, broadband infrastructure will be built taking both investment efficiency and the needs of communities into account. Specifically, the following will be used in addition to ADSL and cable modems: (a) Wireless broadband using wireless LAN and other technologies; (b) Integrated broadband, in which “wireless and ADSL/VDSL”, “optical fiber and infrared transmission”, or “optical fiber and ADSL (in so-called Fiber To The RT (FTTR))” are integrated. (3) Of these varieties of broadband service, super-high-speed broadband access, mostly based on FTTH, will cover 90% of households nationwide. 9 (C)2007NTT Dramatic increase in the number of FTTH subscribers Number of users (Million) 16.0 14.0 12.0 10.0 Optical access is being promoted so aggressively that the number of FTTH subscribers is 8.0 of DSL subscribers has now gradually begun to fall. 6.0 4.0 2.0 0.0 02 Q2 02 Q4 03 Q2 03 Q4 growing rapidly and the number 04 Q2 04 Q4 05 Q2 05 Q4 06 Q2 06 Q4 07 Q2 CATV DSL 07 Q4 FTTH ADSL (NTT) Source: Ministry FTTH (NTT) Affairs and Communications of Internal (C)2007NTT 10 Intense competition in broadband access •Competition in the telecommunication market is intensifying in Japan. •NTT faces strong competition in gaining share in broadband access.
