Serial high-speed WAN card (HWIC) for T1 provides highly flexible connections for Routers

HWIC-1DSU-T1 replaces WIC-1DSU-T1 V2 cards. 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

These highly flexible WICs facilitate WAN access and aggregation and legacy protocol transport-

WAN Access and Aggregation
Serial interfaces can be used to provide WAN access for remote sites. The HWIC-1DSU-T1 also offers an
integrated CSU/DSU, simplifying configuration and management. Integration allows management of the
router and CSU/DSU as a single SNMP entity while also providing detailed troubleshooting capabilities.
Troubleshooting features include self-test, loopbacks, CSU/DSU reset, alarm counters, and T1 statistics.

Legacy Protocol Transport
Serial and synchronous/asynchronous ports are ideally suited to transport legacy traffic across a TCP/IP
network, facilitating network convergence (Figure 3) and 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

Supported Platforms
Cisco 1841, 1941, 2801, 2811, 2821, 2851, 2901, 2911, 2921, 2951, 3825 and 3845 routers
