The SuperStack II NETBuilder 221 boundary router comes with 1 Ethernet port, 1 RS-232 WAN port, and 1 backup WAN port. This router requires a SuperStack II 227 router or a NETBuilder II platform at a central location. Supported WAN protocols include PPP, Frame Relay, and X.25. Routing protocol support (in conjunction with the central router) includes IP, IPX, XNS, OSI, AppleTalk, DECnet, and Vines.

This router is part of 3Com's complete family of SuperStack NETBuilder platforms. These remote access products offer extensive upgradability and the choice of routing in SuperStack platforms or stand-alone configurations. Cost-saving WAN features include industry-standard data compression, bandwidth-on-demand, smart filters, and dial-on-demand support. For IBM support, SuperStack II NETBuilder products offer 3Com's Boundary Routing system architecture optimized for SNA, BAN for native SNA over Frame Relay, and Data Link Switching (DLSw) to tunnel SNA and NetBIOS traffic over IP networks. With Boundary Routing architecture, the remote device does not need to perform packet routing, route management, or network management. It only has to decide whether to pass each packet to the WAN. All other router tasks and all expert administration take place on the NETBuilder II or SuperStack II NETBuilder 227, 327, 427, or 527 router at the central site.
