ACS-PRI/BRI Card Configuring ISDN Features
You must assign an interface ID to any WAN link that will contain B channels before you will
be able to assign the specific B channels to that facility. If you assign a B channel to a WAN
that is not assigned an Interface ID, the system message, "Intf.ID must be uniquely identified,"
will appear when you try to activate the D channel. In the example shown in Figure 6-9, for D
channel #1, the user plans to assign B channels on WAN 1-1, 1-2 and 2-1.

configuration screen.
