Japan's J:COM Deploys pre-DOCSIS 3.0 with ARRIS

J:COM, the largest multiple system operator (MSO) in Japan with 2.62 million subscribing households, is deploying the ARRIS FlexPath pre-DOCSIS 3.0 wideband channel bonding solution to its residential customers, enabling Internet service capable of downstream speeds of 160 Mbps, and upstream speeds of 10 Mbps.

The service carries the brand "J:COM NET HIGHGRADE", and will be offered to customers living in single dwelling units, individual homes and smaller apartment buildings within the J:COM network footprint beginning this month. Initial J:COM NET HIGHGRADE service deployments are in the Kansai area at the Minami Osaka, Izumi, and Izumi Ohtsu systems.

J:COM is using the ARRIS C4 CMTS situated in J:COM's headend and ARRIS Touchstone Wideband Modems WBM650C in the customer premises.

ARRIS said its FlexPath software can be installed into existing C4 CMTS with a simple software upgrade and all legacy DOCSIS modems -- 1.0, 1.1 and 2.0 -- can coexist on the same downstream channels as the FlexPath modems. The Touchstone Wideband Modem WBM650 delivers end-user data speeds of up to 160 Mbps in the downstream and up to 120 Mbps in the upstream. It does this by bonding up to four 256-QAM DOCSIS channels using packet-based bonding. The company also noted that its C4 CMTS is fully upgradeable to DOCSIS 3.0 and the Touchstone Wideband Modems WBM650 are forward compatible with DOCSIS 3.0.

  • In November 2006, ARRIS announced that Hyundai Communications and Network (HCN), South Korea's third- largest cable system operator serving over 1.1 million video customers, is now delivering full duplex data speeds in excess of 100 Mbps to its customers using the ARRIS FlexPath wideband data solution.

  • In September 2006, ARRIS announced that Korea's KCTV JEJU Broadcasting completed field testing of its wideband data solution.
