Which statement best describes channel bonding in DOCSIS networks?

• A. It reduces the need for a separate return path.
• B. It aggregates multiple downstream/upstream channels to increase total throughput.
• C. It shortens the length of coax cable.
• D. It stops interference by limiting channels.

Answer: (B)

Channel bonding in DOCSIS networks means combining multiple downstream (and/or upstream) channels into a single, wider pathway so data can flow in parallel. This lets the modem achieve higher total throughput because several channels are being used at the same time rather than just one. It doesn’t shorten the coax cable, nor does it eliminate the need for a return path—the upstream channels still carry data back to the network. It also isn’t about stopping interference by limiting channels; bonding increases capacity by using more channels in parallel.
