ADVANCED NETWORK & TELECOM SYSTEMS
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.
SB3100/SB3100i/SB3100D SB3100/SB3100i/SB3100D
3 models available: SB3100, SB3100i
international version, and the
SB3100D dual mode
Hardware ready for DOCSIS 1.1
Attractive compact design
(40% smaller casing than the SB2100)
Improved LEDs for troubleshooting
