CableLabs Certifies DOCSIS 3.0 Gear: Six Modems, 3 CMTSs

CableLabs awarded certification status for Data over Cable Service Interface Specification (DOCSIS) 3.0 cable modems to Ambit, Arris, Cisco, Motorola for two modems; and SMC. This represents the first certification of DOCSIS 3.0 cable modems.

CableLabs also awarded "full" qualification status for Cable Modem Termination Systems (CMTS) to Casa Systems for two devices. This is the first qualification of a DOCSIS 3.0 CMTS representing "full" or complete compliance with all requirements of the DOCSIS 3.0 specification for headends. Motorola received bronze qualification for its CMTS. CableLabs noted that the headends were tested under a tiered program that was created as a way to encourage CMTS makers to submit gear for testing earlier than they otherwise might have done.
The three-tiered program for CMTS qualification--bronze, silver and full--progressively scales compliance with some of the more long term DOCSIS 3.0 CMTS requirements.

DOCSIS 3.0 achieves the higher data rates through channel bonding in both the upstream and downstream directions. In addition, DOCSIS 3.0 is backward compatible with all existing DOCSIS products.
