Serial and asynchronous high-speed WAN interface cards (HWICs) provide highly flexible connections for Cisco
®
1800, 2800,
and 3800 series integrated services routers. These HWICs help customers to enable applications such as WAN aggregation,
legacy protocol transport, console server, and dial access server. Customers 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 Systems
®
offers five serial and asynchronous HWICs:
1.
Cisco 1800/2800/3800 series 4-Port Serial High-Speed WAN Interface Card (HWIC-4T)—Four high-speed serial ports (Figure 1, A)
2.
Cisco 1800/2800/3800 series 4-Port Asynchronous/Synchronous High-Speed WAN Interface Card (HWIC-4A/S)—Four low-speed
synchronous/asynchronous ports (Figure 1, B)
3.
Cisco 1800/2800/3800 series 8-Port Asynchronous/Synchronous High-Speed WAN Interface Card (HWIC-8A/S-232)—Eight low-speed
synchronous/asynchronous ports, EIA-232 only (Figure 1, C)
4.
Cisco 1800/2800/3800 series 8-Port Asynchronous High-Speed WAN Interface Card (HWIC-8A)—Eight asynchronous EIA-232 ports
(Figure 1, D)
5.
