DOCSIS 3.1 In Your Plant Now In last month's article we focused on demystifying OFDM in DOCSIS 3.1. If you did not read the article please do, because we are going to now build on what we learned last time in the Broadband Library DOCSIS Online article titled “OFDM, completely new in DOCSIS 3.1”. You can find it in the archives with this link: bit.ly/OFDM3 - Also, for those not familair with bit.ly, its just a URL shortening service. Just click on the link or type it into

DOCSIS 3.0 Tutorial – Upstream Channel Bonding

Mia Colabrese2021-11-24T09:39:36-05:00August 22nd, 2010|

The focus of this article will be on the mechanics of upstream channel bonding and how it works more from a DOCSIS protocol perspective. Much more detailed information can be found in the DOCSIS 3.0 MULPIv3.0 document located in the Library, but this will provide a high level overview for the layman who is curious about the basics. First lets understand that it is the cable modem that is doing the channel bonding, remember in the upstream the cable modem transmits data to the CMTS. Per DOCSIS 3.0, the CM can bond from one to four channels in the upstream as coordinated by the CMTS. The CM is always under control by the CMTS.

The first part of this article (in CT's March 2009 issue) discussed downstream potential issues, while this one focuses on the potential issues associated with upstream deployments. In particular, this article covers the critical upstream areas that one should be aware of when getting ready to deploy or already deploying DOCSIS 3.0.
