Predictable Performance
with the SuperStack II
Platform
The unique SuperStack II system
gives the SuperStack II NETBuilder
SI platforms unmatched perfor-
mance and reliability advantages,
setting them apart from comparable
platforms. 3Com SuperStack II sys-
tems integrate router operations for
WAN connections with hubs and
switches for local networking with
configurations that provide an
added level of flexibility and fault
tolerance, including RPS and UPS.
Predictable system performance is
guaranteed with the ability to per-
form simultaneous functions, such
as compression and data prioritiza-
tion, without compromising the
ability to handle as many additional
packet-handling functions as
needed. 3Com is the only vendor to
offer a complete Fast Ethernet solu-
tion in such a wide range of
stackable platforms.
Flexible WAN Services
The routers’ FlexWAN ports sup-
port leased dial, Frame Relay, X.25,
async, and SMDS, with FlexWAN
cables that support virtually all elec-
trical interfaces including RS-449,
RS-232, V.35, EIA 530, X.21, as
well as DTE and DCE connections.
All these features combined provide
the market’s most flexible WAN
services platform.
