Cisco HWIC-4A/S 4-Port Async/Sync Serial HWIC

Cisco interface cards are classified according to the technologies they support. For example, WAN interface cards (WICs) support WAN technologies, such as Gigabit Ethernet; and voice interface cards (VICs) support voice technologies. Voice/WAN interface cards (VWICs) can support voice, data, and voice and data applications, depending on the capabilities of the router in which the VWIC is installed. Enhanced High-speed WAN interface cards (EHWIC) provide expanded LAN and WAN capabilities, such as Gigabit Ethernet and Ethernet switching.

HWIC-4A/S is 4 ports low-speed synchronous/asynchronous interface module for 1800/1900/2800/2900/3800/3900 Series integrated services Routers. With integration of module to the router can either transporting traditional traffic across a TCP/IP network or connecting with console and craft ports to manage network remotely. The HWIC-4A/S provides four serial async/sync ports using Smart Serial connectors and cabling. Each port can operate up to 256 Kbps in sync mode, or up to 230.4 Kbps in async.
