DOCSIS 3.0 Impaired Service
"Impaired Service" in which case one or more bonded upstream channels are impacted by upstream RF impairments while other bonded channels are not. Since subscriber data is striped (that is broken into pieces and spread across each upstream channel and then re-assembled by the CMTS), some of the data will be lost or have errors while other data will not. Subscribers will most likely notice an impaired condition as upstream data rates slow down due to TCP/IP transmissions and/or VoIP, gaming, teleconferencing and other real-time applications will be noticeably impacted.

DOCSIS 3.0 Partial Service
Partial Service is a new term encountered in the DOCSIS 3.0 MULPI specification and realized in field deployments of DOCSIS 3.0 cable modems using upstream bonding. This was a topic that I touched on in this years SCTE Cable-Tec Expo, but will explore in greater detail in this article. Partial service can be considered a feature because the cable modem will stay online even when one or more upstream transmit channels goes offline.

Fresh Tech | DOCSIS Protocol Analyzer – Can’t stop a good idea!
When I first heard rumor that a knew company had a DOCSIS protocol analyzer floating around I had to see it! With full disclosure, many of you know that after 10 years in RF and fiber-optic transport equipment, I spent a few years designing, marketing and selling DOCSIS protocol analyzers. More specifically I focused on making them available to cable operators because I knew they could detect really difficult to isolate problems. Averna know owns the technology from my Sigtek days, so it is nice to see a new competitor in the space. What's more is that its nice to see this competitor at SCTE Cable-Tec Expo who is interested in cable operator's issues.

BTR | Rollouts Continue as DOCSIS 3.0 Matures
The following article just released by Broadband Technology Report was written by Carl Weinschenk. A number of us from the industry contributed to Carl's piece, but it is a nice high-level summary article on the status of DOCSIS 3.0. Below you will find a snippet of the article with a link to the BTR website for the complete read. Enjoy. Rollouts Continue as DOCSIS 3.0 Matures There are just two areas of concern as the rollout of DOCSIS 3.0 continues: the upstream and the downstream. Observers seem satisfied

Why are my DOCSIS 3.0 cable modems transmitting at 52.2 dBmV?
A recent question from a reader provided an interesting response - the answer: maximum transmit power is 52.2 dBmV for DOCSIS 3.0 cable modems under certain conditions. The answer is very simple. They were transmitting at their maximum transmit level. That being in a 16-QAM modulation with four bonded upstream channels.
