Data Sheet
Cisco ISDN BRI S/T WIC for the
Cisco 1600, 1700, 2600, 3600, and 3700 Series
Introduction
Four versions of the ISDN Basic Rate Interface (BRI) S/T WAN interface card (WIC) exist (product numbers: WIC36-1B-S/T, WIC-1B-S/T, and WIC-1B-S/T-LL, see Figure 1). Offering a single ISDN BRI S/T interface, these WICs may require an external Network Termination 1 (NT1), depending on the region of the world. The WICs insert 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 through a WIC enables administrators to maximize valuable slot space while providing additional connectivity options, such as Ethernet, on the same module.
Note: The WIC with part number WIC-1B-S/T-LL is for leased-line BRIs.

WIC-1B-S/T
You can tell the difference between the BRI-S/T WICs in the following ways:
- The product number is printed on a label on the under side of the WIC.
- The WIC36 has a keying tab on the left side of the WIC.
- The WICs with part numbers WIC-1B-S/T have an "OK" LED.
- Use the Cisco IOS® show diag command to see which WIC is in a network module.

Note: The Cisco IOS Software releases provided are typically the minimum version required to support the platform, module, or feature in question. Use the Software Advisor to choose appropriate software for your network device: match software features to Cisco IOS and Cisco Catalyst® Operating System (Catalyst OS) releases, compare Cisco IOS releases, or find out which software releases support your hardware. The Software Advisor and other tools are available in TAC Tools for Access-Dial Technologies.
Configuration
The WIC BRI interface configuration is similar to any other BRI interface. When the WIC is inserted into the router, it behaves like any BRI interface built into the router (for example, Cisco 800 and 1600 series routers).
If you need to troubleshoot the BRI circuit, refer to the BRI Troubleshooting flowchart.
