With Cable-plus Phone, KDDI provides the portion equivalent to NTT East/NTT West subscriber lines through partnership with cable television companies, reducing its basic rate than before. In addition, KDDI reduces calling rates by using its own high-quality IP network as relay telephone network. Accordingly, a fee structure that is less expensive and simpler than ever before has been established.
