DENVER – Some comments made here at the SCTE Cable-Tec Expo suggest that the so-called “DOCSIS 2.0b” project – considered a shorter-term, interim step to DOCSIS 3.0 -- is anything but a slam dunk.
Speaking during the morning technical session Wednesday, CTOs from Comcast Corp. and Adelphia Communications said they remain committed to DOCSIS 3.0, and are not much interested in an interim step, particularly if there are any questions about whether it is forward-compatible with DOCSIS 3.0 gear or backward-compatible with DOCSIS 2.0.
DOCSIS 2.0b, as it’s been described, looks to bond a minimum of two DOCSIS 2.0 downstream channels, but does not bond any upstream channels.
The focus remains on 3.0 and getting those specs finalized, said Adelphia CTO Marwan Fawaz. He said today’s DOCSIS 2.0 technology should, in the coming couple of years, be able to handle data speeds Verizon or any other competitor throws into the marketplace.
David Fellows, the EVP and CTO of Comcast, said his company may look into testing 2.0b, but he would not be a fan of anything that stands in the way of DOCSIS 3.0’s progress.
