Building upon the success of the SB6120, Motorola's SURFboard SB6121 delivers your complete personal media experience, at lightning-fast broadband speed. It harnesses the power of DOCSIS 3.0 technology to bond up to four downstream channels and four upstream channels--providing you advanced multimedia services with data rates of more than 100 Mbps in each direction. That makes gaming, shopping, downloading, working, high-quality video conferencing, and peer-to-peer networking applications far more realistic, faster, and efficient than ever before.

Please note: This modem is for Internet only. If your cable provider offers a bundled service with telephone (e.g. Comcast XFINITY Voice or Triple Play) you will need to get a specialized modem from them.
