Cisco WIC-1B-S/T-V3= Internal networking card

1-Port ISDN WAN Interface Card (dial and leased line) Features
- One ISDN BRI port (S/T interface, requires external NT1)
- Utilizes an RJ-45 connector
- Supported Onboard, NM-1FE2W-V2, NM-1FE1R2W, NM-2FE2W-V2 and NM-2W

Benefits of an Integrated, Fully Managed Solution
The network modules provide various port densities to meet customer requirements at various price points. The optional, integrated NT1 lets customers consolidate customer premises equipment (CPE) to provide multifunction dial access server, router, and other capabilities within the Cisco routers in power-branch-office environments.
The WAN-interface-card (WIC) option offers a single ISDN BRI port (with optional NT1). The WIC-1B-S/T-V3 inserts into a mixed-media network module (part number NM-1FE2W-V2, NM-2FE2W-V2, NM-1FE1R2W or NM-2W) or is supported on the Cisco 1700 Series, Cisco 1800 Series, Cisco 1900 Series, Cisco 2600XM Series, Cisco 2800 Series, Cisco2900 Series, Cisco 3700 Series,Cisco 3800 Series and Cisco 3900 Series routers. It provides a cost-effective ISDN router with the following benefits of integration:

- Fewer devices and cables to deploy and manage
- Remote and local configuration, monitoring, and troubleshooting via the Cisco IOS® Software CLI and Simple Network Management Protocol (SNMP)
- Flexibility and investment protection
- Single-vendor support
- Enhanced reliability
- Physical space savings

The ability to add BRI connectivity via a WIC enables administrators to maximize valuable slot space while providing additional connectivity options on the same module such as Fast Ethernet.

Flexibility and Investment Protection
The Cisco 1 port BRI-S/T WIC extends the Cisco commitment to providing customers with maximum flexibility and investment protection through modular WICs that are supported on award-winning router platforms. When WAN bandwidth requirements or service provider pricing change, users can easily change WAN services either by changing the software configuration or replacing the WIC. Because the same card can be used on Cisco 1600, 1700, 1800, 1900, 2600, 2800, 2900, 3700, 3800, 3900 Series Integrated Services Routers, the number of stocking units can be reduced, and the WIC can be redeployed from one platform to another.

Enhanced Reliability
An integrated solution has fewer components; hence, fewer points of failure (for example, one less power supply and fewer cables). This leads to enhanced reliability.

Consistency with WIC-1B-S/T
The Cisco WIC-1B-S/T-V3 offers all of the features of the Cisco WIC-1B-S/T and can be smoothly deployed without requiring any additional learning.
