Cable Modem
Motorola's next generation, SURFboard SB4220
Cable Modem, incorporates the latest DOCSIS 2.0
Advanced Time Division Multiple Access (A-TDMA)
technology that provides up to 30 Mbps upstream
data rate in a DOCSIS 1.1 certified cable modem.
Competitively priced, the SB4220 includes
all the features of previous SURFboard Cable Modems,
including USB connectivity, software upgrades
available over the network, advanced RF design,
top-notch field reliability and high-performance

USB interface connectivity to help ensure compatibility
with almost any PC or Macintosh network-ready
computer system.
