• In North America and Australia, a network termination device (NT1) is
required. Connect one end of the ISDN cable to the WAN Adapter, and
connect the other end to the S/T interface connector on your NT1. Connect
one end of the cable provided with your NT1 to its U interface connector, and
connect the other end to the wall jack installed by your ISDN service provider.
These connections are shown in Figure 5 below.
