J:COM to bond with 160 Mbps Internet service

J:COM, the largest cable MSO in Japan, will use pre-DOCSIS 3.0 channel bonding techniques to deliver a super-fast Internet service that caps downstream speeds at 160 Mbps, and upstream speeds at 10 Mbps.

The service, which carries the provisional brand of "J:COM.NET 160 Mbps," will be offered to individual homes and customers beginning in April 2007 in the operator's Kansai Minami Osaka system service area. J:COM said it plans to extend the service to other regions, as well.

J:COM will sell the new service for ¥6,000 (approximately US $50.50 ) per month.

The faster, DOCSIS-based offering for individual homes complements the MSO's "JCOM.NET Hikari" offering, which delivers symmetrical speeds of 100 Mbps to multi-dwelling unit (MDU) customers. Rather than leveraging DOCSIS and the traditional HFC network, the Hikari service is fed to MDUs via fiber. Once inside the MDU, the service then taps into the existing coax by leveraging a network system and modem/gateway powered by silicon from Entropic Communications, one of the founding members of the Multimedia over Coax Alliance. J:COM launched the Hikari MDU service in August 2005.

The decision to launch the new DOCSIS-based service follows a trial J:COM conducted in August 2006. The MSO did not disclose its cable modem and cable modem termination system (CMTS) partners for the commercial launch in the release, but Motorola Inc. has been linked to some of J:COM's earlier trial work with DOCSIS downstream channel bonding.
