Introduction
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.
