At last, the wait is over.
SURFboard technology leaves
traditional modems obsolete.
Waiting. It may be the greatest irritant in web surfing.
Waiting for your modem to transfer a document. Waiting
for the busy signals to stop; waiting for a connection.
Waiting. With GI's SURFboard cable modem, the waiting
is over. You're always on...always connected.
GI offers 3 models in the SURFboard cable modem
family: the SB2100, SB2100i and the SB2100D. The
standard SB2100 offers customer friendly, quick Internet
access via a single cable. The SB2100i international
modem supports universal power supplies providing
GI's plug-and-play convenience to customers across the
globe. Additionally, the SB2100D dual-return modem
automatically detects available return path in one-way or
two-way plants and configures itself accordingly. The
SB2100D is the same unit as the SB2100, but with facto-
ry added components like an analog telephone modem
included inside for one-way systems.
SB2100/SB2100i/SB2100D SB2100/SB2100i/SB2100D
3 models available: SB2100, SB2100i
international version, and the
SB2100D dual-return
High-Speed Access creating more
"bandwidth per dollar" with speeds up
to 100x's faster than 28.8 telco dial-in
Telco equipment limitations
eliminated with RF-return
cable modem
Increase return on investment for
plant upgrades
Cable operator can compete today
as high-speed data service provider
DOCSIS standardization and
interoperability of cable modems
provide longevity of purchased
headend equipment
Supports up to 32 users
