J:COM Deploys DOCSIS 3.0 with Cisco

Japan's Jupiter Telecommunications (J:COM) has begun deployment of the Cisco DPC3000 DOCSIS 3.0 Channel Bonded Cable Modem for use in its J:COM NET Ultra 160M Course broadband service, which offers download speeds of up to 160 Mbps.

The Cisco DPC3000, which has received CableLabs DOCSIS 3.0 certification, uses four bonded channels for both the downstream and upstream data, enabling downstream data rates in excess of 160 Mbps and upstream data rates up to 120 Mbps. It is designed to be backward-compatible for use as a single-channel cable modem with DOCSIS 2.0, 1.1 or 1.0 networks.

In addition to DOCSIS 3.0-compliant cable modems, the Cisco downstream channel-bonding solution features the Cisco uBR10012 cable modem termination systems (CMTS) and Cisco xDQA-24 edge quadrature amplitude modulators (QAMs).

  • In April 2008, Motorola announced that Jupiter Telecommunications (J:COM), Japan's largest multiple system operator (MSO), had selected Motorola's channel bonding technology to deploy the company's first DOCSIS 3.0-based Cable Modem Termination System (CMTS) and cable modems. Specifically, Motorola said the deployment uses its DOCSIS 3.0-based BSR 64000 CMTS/Edge Router and SURFboard SB6120 cable modems. Financial terms were not disclosed. Motorola said its solution is capable of delivering up to 160Mbps throughput to residential and commercial customers.
