Serial & Asynchronous High-Speed WAN Interface Cards for Cisco Integrated Services Routers .


Models:
  • 4-Port Serial High-Speed WAN Interface Card (HWIC-4T)-Four high-speed serial ports
  • 4-Port Asynchronous/Synchronous High-Speed WAN Interface Card (HWIC-4A/S)-Four low-speed synchronous/asynchronous ports
  • 8-Port Asynchronous/Synchronous High-Speed WAN Interface Card (HWIC-8A/S-232)-Eight low-speed synchronous/asynchronous ports, EIA-232 only
  • 8-Port Asynchronous High-Speed WAN Interface Card (HWIC-8A)-Eight asynchronous EIA-232 ports
  • 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.

WAN Aggregation
Serial interfaces can be used to aggregate WAN connection from remote sites. With support for serial speeds up to 8 Mbps per port, the 4-Port Serial High-Speed WAN Interface Card is ideal for low- and medium-density WAN aggregation.

Legacy Protocol Transport
Serial and synchronous/asynchronous ports are ideally suited to transport legacy traffic across a TCP/IP network. This enables network convergence, eliminating costly separate leased lines for this traffic. Legacy protocols supported by Cisco IOS® Software include:

  • Systems Network Architecture (SNA) and Synchronous Data Link Control (SDLC) Protocol
  • Binary Synchronous Communications Protocol (Bisync)
  • X.25 Protocol

Console and Terminal Server
Asynchronous ports provide highly flexible connections that allow access to EIA-232 devices across a TCP/IP network. This allows out-of-band management to console or craft ports, allowing the network operator to manage a network of remote devices from a central location.

Dial Access Server
Asynchronous HWICs can connect to external dial modems to provide low-density dial access servers.

Connectors and Cabling
Serial and asynchronous HWICs have connectors and cabling that allow high port densities in the compact HWIC form factor.

Smart Serial Cabling
The 4-Port Serial High-Speed WAN Interface Card and 4-Port Asynchronous/Synchronous High-Speed WAN Interface Card each have four Smart Serial ports. These ports use the same connectors and cabling as the WIC-2T and WIC-2A/S.

High-Density Synchronous/Asynchronous Cabling
The 8-Port Asynchronous/Synchronous High-Speed WAN Interface Card uses two high-density 4-port connectors. Each connector supports four ports of EIA-232 with data communications equipment (DCE) or data terminal equipment (DTE) interfaces. All four ports on one cable use the same DTE/DCE mode.

High-Density Asynchronous Cabling
The 8-Port Asynchronous High-Speed WAN Interface Card and 16-Port Asynchronous High-Speed WAN Interface Card 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 DB-25 DTE or DB-25 DCE connections.

Platform Support
Serial and asynchronous HWICs are supported in the HWIC slots of Cisco 1800, 1900, 2800, 2900, 3800 and 3900 series integrated services routers.
