Cisco WAN Interface Card HWIC-1DSU-T1

High Speed WAN Interface Card

Cisco HWIC-1DSU-T1

Serial and asynchronous high-speed WAN interface cards (HWICs) provide highly flexible connections for Cisco select series integrated services routers. 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 support.

The Cisco 1-Port T1/Fractional T1 DSU/CSU WAN Interface Card 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.
