The Best WAN Value The SuperStack II NETBuilder SI platforms deliver today's best overall WAN value with built-in, easy-to-use IP firewalls that provide secure LAN-toWAN traffic as well as protection from Internet intrusion. Predictable system performance, robust multiprotocol routing, and integrated telecommunications functionality make the SuperStack II NETBuilder SI devices the most cost-effective, complete regional office solution for changing wide area networking needs in a secure environment. The platforms can either be used as a remote office connection or as a central site solution in combination with 3Com OfficeConnect® NETBuilder routers in remote branch offices. Cost-Effective Flexibility with Telco Interface Modules The SuperStack II NETBuilder SI platforms have all the functionality you need right from the day you purchase them. When your network requirements change, or you want to change WAN services, you can easily and affordably convert the existing interface by replacing the telco modules. SuperStack II NETBuilder SI ISDN U Module The SuperStack II NETBuilder SI ISDN U module provides an integrated solution for ISDN U interfaces by automatically converting an S/T base unit to ISDN U without the need for additional exterior hardware. SuperStack II NETBuilder SI 56/64 Kbps DSU/CSU Module The SuperStack II NETBuilder SI 56/64 Kbps DSU/CSU module plugs directly into the telco port of the S/T base device, providing an integrated DSU/CSU solution. The module is standards-based to ensure interoperability with a wide range of vendors' equipment. SuperStack II NETBuilder SI FT1/T1 DSU/CSU Module The SuperStack II NETBuilder SI FT1/T1 DSU/CSU module plugs directly into the telco port of the S/T base device, providing an integrated FT1/T1 DSU/CSU solution. The module is standards-based to ensure interoperability with a wide range of vendors' equipment. Enterprise OS Software Features 3Com's Enterprise OS software provides wide-ranging support for internetworking on all NETBuilder platforms and PathBuilder tunnel switches with standards-based features and functionality. s The SuperStack II NETBuilder SI platforms support bridging and multiprotocol routing (IP, IPX, AppleTalk, SNA) over Frame Relay, PPP, ISDN, leased and dial lines (Sync and Async), X.25 and SMDS. s Bandwidth Grooming and data compression features reduce WAN bandwidth utilization and packet transmission time, dramatically reducing usage fees. Features include data prioritization to orga- nize traffic into high-medium-low transmission priority queues, bandwidth aggregation to bundle available links into one flexible pipe, and protocol reservation to assign a fixed percentage of the available bandwidth to a particular protocol or traffic type. s Resource Reservation Protocol (RSVP) provides dynamic quality of service (QoS) for outbound traffic on PPP and Frame Relay virtual ports. s Auto-dial backup and disaster recovery features, such as dial on demand (DOD), bandwidth on demand (BOD) and Virtual Router Redundancy Protocol (VRRP) ensure network reliability and costeffective WAN management. The platforms offer a complete legacy solution for even the most complex IBM environments, integrating multiple types of SNA/legacy devices onto a TCP/IP backbone with comprehensive legacy features such as SDLC, Data Link Switching, IBM NetView support, Binary Synchronous Communications (BSC) conversion and QLLC conversion. Robust Security The platforms provide robust network security with built-in ICSA-certified IP firewalls at every network interface. The firewall includes easy-to-use predefined filters to guard against a number of common intrusions. You can also define your own filters and use the on-board traffic simulator to send test packets through the firewall to confirm the configuration's security. For additional security, the platforms support NAT which gives private TCP/IP networks Internet connectivity without reconfiguring end stations with publicly registered IP addresses. This not only alleviates the administrative burden, but also conceals the internal address structure from public view, preventing direct access to an inside host. In addition, NAT provides address redirection and load balancing of TCP traffic, smoothing integration with the Internet. Flexible Modules SuperStack II NETBuilder SI telco interface modules offer flexibility for changing WAN needs. 2
