The resulting lakes existed until their downstream channels became wide enough to drain them.

The central ComController switch was a modular system offering one downstream channel (transmitter) and one management module.

After the Mekong's waters crest-when its downstream channels can handle the volume of water-the flow reverses, and water flows out of the engorged lake.

Once upstream and downstream channels are established, a subscriber can connect to a service such as an Internet service provider.

One downstream channel can handle hundreds of cable modems.

As video traffic continues to grow, this means that significantly more CMTS downstream channels will be required to carry this video content.

The downstream channels in DOCSIS are organized into slices of frequency groups with guard band between them.

Uplink or downlink (upstream or downstream channel)

Likewise, persistent upstream errors will cause a cable modem to "reinitialize its MAC" and scan for new downstream channels.

Set-top out of band data is generally present only on certain downstream channels.
