HWIC-16A 16-Port Asynchronous High-Speed WAN Interface Card (HWIC-16A)-Sixteen asynchronous EIA-232 ports
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 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.
Asynchronous ports provide highly flexible connections that allow access to EIA-232 devices across a TCP/IP network. This capability allows out-of-band management of console and craft ports, allowing the network operator to manage a network of remote devices from a central location
The Cisco 8-Port Asynchronous HWIC and 16-Port Asynchronous HWIC use one (HWIC-8A) or two (HWIC-16A) high-density 8-port connectors. The 8-port asynchronous cable provides the high-density connector on one end and eight RJ-45 plugs on the other. RJ-45- to DB-25 modular adapters are used to convert the RJ-45 to a DB-25 DTE or DB-25 DCE connection.
