Japan Telecom Holdings Co., a unit of British wireless giant Vodafone Group PLC, said Wednesday it is in talks with several firms, including U.S. investment fund Ripplewood Holdings LLC, over the sale of its fixed-line subsidiary, Japan Telecom Co.

But no decision has been made yet, the Japanese telecom firm said in a brief statement.

According to sources, Vodafone intends to sell Japan Telecom, the nation's third-largest fixed-line carrier, for around 300 billion yen.
