The SuperStack II system is 3Com’s industry-leading integrated network architecture with an advanced feature set to carry your network into the next century. Simple to install, use, and manage, SuperStack II products deliver scalability across each key network parameter—performance, density, connectivity, and LAN technology —to give you complete freedom to grow your network on your terms. You can easily build and rebuild stacks to accommodate change while simultaneously protecting existing infrastructure investments.

These upgradeable, compact, SuperStack II routers or stand-alone Token Ring routers include the SuperStack II NETBuilder 327 router for multiprotocol routing and SuperStack II NETBuilder 323 router for SNA Boundary Routing technology. Each includes software, documentation, an integrated UTP and STP Token Ring LAN connection (supporting either 4 or 16 Mbps), connectors (including an advanced redundant power system connector), and a rack mount kit to eliminate the need for extra cables and components. Support for Transcend network management software provides an easy-to-use graphical interface with a common look and feel, and SNMP MIB II compliance supports many standard MIBs. Loaded with features and competitively priced, these routers offer convenience, rich functionality, and real value.

• Upgradeability (SuperStack II NETBuilder 323 to 327 router functionality) protects your investment and simplifies growth

• 3Com’s optional advanced redundant power system, uninterruptible power system, and -48V DC power systems ensure mission-critical fault tolerance; see pages 13-2 to 13-4 for details

• Router software supports industry-standard data compression and dial services to increase effective bandwidth and reduce dial-up line usage fees; bandwidth-on-demand to handle peak traffic; dial-on demand to control line use; and smart filters to block superfluous remote traffic
