Product description from manufacturer
3Com's suite of SuperStack II NETBuilder solutions provides an unmatched combination of robust features and superior ease-of-use. Loaded with features and competitively priced, these solutions deliver full value and functionality. Whether your network requires links to small, midsize, or large branch offices, 3Com has the right choices - including Ethernet, Token Ring, and ISDN interfaces, Boundary Routing cost savings, and SuperStack II capabilities. SuperStack II NETBuilder 52x series routers support ISDN to bring end-to- end digital dial services to remote LANs. ISDN delivers the fast call setup needed to support routing protocols and the transmission speed to easily surpass analog modems. SuperStack II NETBuilder 52x series routers support two ISDN 64 Kbps data channels and one 16 Kbps control channel via the ISDN Basic Rate Interface (BRI). The two data channels can be used independently to connect different locations or as a single logical connection to a remote site. ISDN end-to-end digital transmission is more accurate and reliable than analog transmission. All-digital transmission is more flexible, too. It offers a range of applications such as integrated voice and data and resource sharing, and it's ideal for teleworking. Adding to ISDN flexibility, SuperStack II NETBuilder 52x series routers offer a choice of Boundary Routing, access routing, or full multiprotocol routing. You also have the option of the ISDN Primary Rate Interface (PRI), providing multiple data channels, with the NETBuilder II bridge/router plus a NETBuilder II WAN Extender 2T1 or 2E1 at the central site. Together, 3Com product advantages and ISDN benefits are unbeatable.
