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

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.
