ABI Research released a study detailing vendors’ opportunities with Cable Television Laboratories’ introduction of Data Over Cable Service Interface Specification 3.0.

The research firm said the transition to DOCSIS 3.0 will take place in two phases. First, cable-modem-termination-system gear must be replaced. Then, “partly by a process of natural replacement over time,” cable modems and set-top boxes in consumers' homes will also change to DOCSIS 3.0-compatible equipment -- often residential gateways supporting triple-play services.

“By delivering interactive IP [Internet-protocol] video to the home over DOCSIS, cable operators shift bandwidth demand on their networks to take advantage of the innovative features offered by IP video," ABI principal analyst Michael Arden said in a prepared statement. "CableLabs' release of this nearly final specification will allow vendors to start developing compatible equipment.”

Arden added, “2007 should see the first volume shipments of DOCSIS 3.0-compliant network equipment. Harmonic, Motorola and Cisco [Systems], already in the field with pre-3.0 designs, will certainly be active.”

Outside of North America, much of the interest in DOCSIS 3.0 has come from Asia, according to ABI.
