The SuperStack II NETBuilder SI bridge/router has two Ethernet ports,
either two or four serial ports depending on the model, and one of the
following WAN ports: ISDN S/T (43x and 53x), ISDN U (44x and 54x),
56/64 Kbps CSU/DSU (45x and 55x), or T1/FT1 CSU/DSU (46x and 56x).
This section describes how to cable each port on your bridge/router.

Boundary router models can use only one Ethernet port and only one
serial or WAN port can be active at a time. You can cable the remaining
serial or WAN ports to be used as back-up. If you upgrade to full router
software, the second Ethernet port and back-up serial ports will be
functional.
