One- and 2-Port Serial and Asynchronous High-
Speed WAN Interface Cards for Cisco 1800, 1900,
2800, 2900, 3800, and 3900 Series Integrated
Services Routers
Speed WAN Interface Cards for Cisco 1800, 1900,
2800, 2900, 3800, and 3900 Series Integrated
Services Routers
Serial and asynchronous high-speed WAN interface cards (HWICs) provide highly flexible connections for Cisco
®
1800, 1900, 2800, 2900, 3800, and 3900 Series Integrated Services Routers. These HWICs help customers
enable applications such as WAN access, legacy protocol transport, console server, and dial access server. You
can mix and match HWICs to tailor cost-effective solutions for common networking problems such as remote
network management, external dial-modem access, low-density WAN aggregation, legacy protocol transport, and
high-port-density support.
Cisco offers four new serial and asynchronous HWICs:
●
Cisco 1-Port T1/Fractional T1 DSU/CSU WAN Interface Card (HWIC-1DSU-T1)
●
Cisco 1-Port Serial WAN Interface Card (HWIC-1T)
●
Cisco 2-Port Serial WAN Interface Card (HWIC-2T)
●
Cisco 2-Port Asynchronous/Synchronous Serial WAN Interface Card (HWIC-2A/S)

Common Applications
These highly flexible interface cards facilitate several important applications:
●
WAN access and aggregation
●
Legacy protocol transport
●
Dial access server
WAN Access and Aggregation
Serial interfaces can be used to provide WAN access for remote sites. With support for serial speeds up to 8
Mbps per port, the 2-port serial HWIC is ideal for low- and medium-density WAN aggregation (Figure 2).
