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
processors. The Motorola SURFboard SB4220 features
a user-friendly, convenient, top-mounted stand-by
switch. The stand-by switch disconnects the USB and
Ethernet connection to the CPE without disconnecting
the cable modem from the RF network, providing
security and flexibility. It offers both Ethernet and
USB interface connectivity to help ensure compatibility
with almost any PC or Macintosh network-ready
computer system.
