Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Introduction

The ISDN Basic Rate Interface (BRI) U WAN Interface Card – version 2 (WIC-1B-U-V2) is now available as a replacement for the WIC-1B-U card that is End-of-Sales. The WIC inserts into a mixed-media network module or directly into the WIC slot on the Cisco 1700, 2600, 3600, 3700 chassis. The ability to add BRI connectivity via a WIC allows administrators to maximize valuable slot space while providing additional connectivity options, such as Ethernet, on the same module.
