Cisco 1-Port Serial WAN Interface Card - For Data Networking - 1 x Serial WAN
Cisco® 4400 Series Integrated Services Router Network Interface Modules (ISRNIMs) provide highly reliable synchronous serial WAN connections for remote sites. These interfaces use well-known point-to-point WAN protocols such as High-Level Data Link Control (HDLC) and Point-to-Point Protocol (PPP) as well as Frame Relay, offering cost-effective virtualized WAN connections in both point-to-point and point-to-multipoint designs. You can mix and match NIMs to tailor cost-effective solutions for common networking solutions for low- and high-density WAN aggregation.
Cisco offers three new synchronous serial NIMs:
- Cisco 1-Port Serial WAN Network Interface Card (NIM-1T)
- Cisco 2-Port Serial WAN Network Interface Card (NIM-2T)
- Cisco 4-Port Serial WAN Network Interface Card (NIM-4T)
