DOCSIS 3.0 cable performance allows bonding of up to eight channels on downloads, and four channels on uploads, when used with the latest cable systems. DOCSIS 2.0 and 1.1 support provides compatibility with older cable systems.
Zoom cable modems are approved for your cable modem service. Zoom Models 5352, 5350, 5341J, 5341, and 5241 work with all cable modem services in the U.S. and most other countries that support North American DOCSIS. They have been certified by CableLabs, the cable service providers’ primary test lab. This is the only certification required by most U.S. cable services including Cablevision, and hundreds of others. Zoom cable modems have also been certified by Comcast, Cox, Time Warner Cable, and the small number of other service providers who require certification beyond CableLabs.
You will find the approved models on the official website of Comcast, Cox, Time Warner Cable, and Bright House.
