Jupiter Telecommunications Co. Ltd. -- the Japanese cable MSO owned by
Liberty Media Corp. and Microsoft Corp., among others -- will launch a
three-month Internet-protocol telephony test Nov. 1.

The company said 100 homes in Urayasu City, Japan, will participate in the
free technical and operational trial.

The MSO is using equipment and technology from Broad Net/Mux Corp./Toshiba
Corp., Motorola Inc., Sonus Networks Inc. and Cross Beam Networks/Terayon
Communication Systems Inc.

The test will focus on call destinations, number portability and emergency
calls, as well as operational issues such as installation, call-cost allocation,
billing and customer service.

It's the second IP trial for Liberty this year. This summer, a Liberty cable
affiliate in Puerto Rico launched an IP-telephony test with Net2Phone
Inc.
