The law concerning the Nippon Telegraph and Telephone Corp. group should be revised to grant more freedom to its two local calling companies and the revision should be a prerequisite to any further cuts in the connection fees it charges other telecommunications firms, the NTT Corp. president said Wednesday.

"In attempting to make further progress in the interconnection charge issue, revision of the law will inevitably become involved," NTT President Junichiro Miyazu told a regular press conference.

Miyazu made the comment in response to Monday's remarks by Hiromu Nonaka, secretary general of the ruling Liberal Democratic Party. Nonaka urged the NTT group to reduce its interconnection fees by supplementing the lost revenue with profits from sales of NTT DoCoMo Inc. stocks.
