The Demise of DOCSIS 1.2?

Facing heat from vendors and operators that have struggled simply to rollout DOCSIS 1.0 products in volume, CableLabs has put plans for adding an advanced PHY to the DOCSIS standard on the back burner. Commonly referred to as DOCSIS 1.2, this next-generation spec was to include Terayon's S-CDMA technology, as well as Broadcom's proposed frequency-agile TDMA solution. CableLabs has asked vendors to take their time and also evaluate other advanced PHY options, such as orthogonal frequency division multiplexing (OFDM), intentionally slowing the DOCSIS 1.2 development timeline.

CableLabs' rationale for the DOCSIS 1.2 slow down is that the benefits of an advanced PHY do not outweigh the damages of market confusion created by unreasonably rapid standards evolution. The last thing MSOs want to hear from consumers is "why bother buying a DOCSIS 1.0 or 1.1 modem when 1.2 is coming?" It is not an untenable position.
