Now you can ride the wave
faster than ever before!
General Instrument has revolutionized the cable
industry once again. Now accessing and surfing the
Net is better than ever. Hold on tight, because the
fastest connection to the Net is here. Introducing
the newest member of the GI SURFboard family, the
SB3100 cable modem—the most dynamic wave in
external cable modem design yet. The SB3100 cable
modem is hardware-ready to support the DOCSIS 1.1
specification standard, which calls for advanced
Quality of Service (QoS) and Internet Protocol (IP)
filtering functions. QoS guarantees increased Internet
access speed to those businesses or homes demanding
it... this translates into increased revenue potential for
subscribers who require quicker connection. The
enhanced processor included in the SB3100 is
5 times faster than its SB2100 counterpart, making
it the fastest in the market and capable of handling
current and future DOCSIS functions.

THE ULTIMATE IN CABLE MODEM TECHNOLOGY!
Power
Flashes while performing startup diagnostics internal to
modem (after initial power-on or reset), and turns solid
green when modem successfully completes diagnostics.
Receive
Flashes while scanning for downstream frequency,
and turns solid green when modem has successfully
acquired a downstream channel.
Send
Flashes while locating and ranging an upstream channel,
and turns solid green when modem successfully ranges
upstream channel.
Online
Flashes while requesting an IP address (DHCP),
downloading the configuration file (TFTP), and getting
network time (TOD). Turns solid green when modem
has successfully completed DHCP/TFTP/TOD and
activities noted above for Power, Receive, and Send.
Activity
Flashes when data is transmitted on the
downstream or upstream connection. If there
is no data traffic, the amber LED remains dark.
