Amendment Application for Optical Subscriber Lines
Interconnection Charges


On January 9, 2008, Nippon Telegraph and Telephone East Corporation ("NTT East") submitted to the Minister of Internal Affairs and Communications an application seeking authorization to revise Articles of Agreement Concerning Interconnection to Designated Telecommunications Facilities, applicable beginning the fiscal year ending March 31, 2009. In response to a request from the Minister, which was based on the report from the Telecommunications Council on March 27, 2008, NTT East submitted today its amendment application to the Minister.


1.Summary
(1) Revision of the demand estimates for optical subscriber lines (dark fiber) that will be used by interconnection service providers.

We changed a part of the demand estimation for optical subscriber lines of the application for the authorization on January 9, 2008. The interconnection demand growth rate observed during the period of demand expansion in the ADSL market is employed to estimate the demand for an optical main subscriber line and an optical branch subscriber line by interconnection service providers.

(2) Revision of the concept of adjustment of disparities between results and forecasts

The concept of disparities to be adjusted in the subsequent calculation period is changed from "difference between actual revenue arising from interconnection charges*1 and actual interconnection cost" to "difference between actual revenue arising from interconnection charges and estimated interconnection costs (estimated revenue arising from interconnection charges*2)".

*1: Actual revenue arising from interconnection charges = actual number of core-cables in use × interconnection charges in the calculation period.
*2: Estimated revenue arising from interconnection charges = estimated number of core-cables in use × interconnection charges in the calculation period.
