shows a router of 2-RU height with:
If physical slot W0 is empty and physical slot W1 contains a 1-port serial WIC, the interface
number in the WIC is numbered Serial 0/0.
If slot W0 contains a 2-port serial WIC and slot W1 contains a 1-port serial WIC, the interfaces
in physical slot W0 are numbered Serial 0/0 and Serial 0/1, and the interface in physical slot W1
is numbered Serial 0/2.
If slot W0 contains a 2-port serial WIC and slot W1 contains a 1-port BRI WIC, the interfaces
in physical slot W0 are numbered Serial 0/0 and Serial 0/1, and the interface in physical slot W1
is numbered BRI 0/0.
The slot number for all WIC interfaces is always 0. (The W0 and W1 slot designations are for
physical slot identification only.) Interfaces in the WICs are numbered from right to left, starting
with 0/0 for each interface type, regardless of which physical slot the WICs are installed in.
