DOCSIS 3.1 uses channel bandwidths of up to 192 MHz in the downstream. [14] Upstream: DOCSIS 1.0/1.1 specifies channel widths between 200 kHz and 3.2 MHz. DOCSIS 2.0 & 3.0 specify 6.4 MHz, but can use the earlier, narrower channel widths for backward compatibility. DOCSIS 3.1 uses channel bandwidths of up to 96 MHz in the upstream. Modulation:

PacketCable 1.0 comprises eleven specifications and six technical reports which define call signaling, quality of service (QoS), codec usage, client provisioning, billing event message collection, public switched telephone network (PSTN) interconnection, and security interfaces for implement a single-zone PacketCable solution for residential Internet Protocol (IP) voice services.
In telecommunications, cable Internet access, shortened to cable Internet, is a form of broadband internet access which uses the same infrastructure as cable television. Like digital subscriber line and fiber to the premises services , cable Internet access provides network edge connectivity ( last mile access) from the Internet service ...
A residential gateway is a networking device used to connect devices in the home to the Internet or other wide area network (WAN). It is an umbrella term, used to cover multi-function networking appliances used in homes, which may combine a DSL modem or cable modem, a network switch, a consumer-grade router, and a wireless access point.
Comcast's business Internet plans are similar to their residential plans, with slightly different speed offerings and prices. Notably, the main difference between Comcast's residential Internet and Business Internet is the lack of a monthly data cap with the business plans. [49]
A cable modem that is unable to acquire an upstream channel will give up and resume scanning for new channels. Likewise, persistent upstream errors will cause a cable modem to "reinitialize its MAC" and scan for new downstream channels. This behavior is appropriate for traditional cable modems, but not for cable set-top boxes.
