Three versions of the ISDN Basic Rate Interface (BRI) S/T WAN interface card (WIC) are available: the WIC36-1B-S/T, WIC-1B-S/T and WIC-1B-S/T-LL. These cards offer a single ISDN BRI S/T-interface. These WICs can require an external NT-1 that depends on the region of the world. The WIC inserts into a mixed-media network module or directly into the WIC slot on the Cisco 1600, 1700, 2600, 3600 or 3700 chassis. The ability to add BRI connectivity via a WIC lets administrators maximize valuable slot space while it provides additional connectivity options, such as Ethernet, on the same module.
Note: The WIC-1B-S/T-LL is for leased line BRIs.
These are the differences between the two:
The product number is printed on a label on the under side of the WIC.
The WIC36 has a keying tab on the left-hand side of the WIC.
The WIC-1B-S/T has an "OK" LED.
Use the Cisco IOS® show diag command in order to see which WIC is in a network module.

The WIC BRI interface configuration is similar to any other BRI interface. Once the WIC is inserted into the router it behaves just as any BRI interface built into the router, for example, Cisco 800 and 1600 Series Routers.
Refer to the BRI Troubleshooting flowchart in order to troubleshoot the BRI circuit.
