Cisco 2-Port Asynchronous/Synchronous Serial WAN Interface Card

The 2-Port Asynchronous/ Synchronous Serial WAN Interface Card helps to enable applications such as WAN access, legacy protocol transport, console server and dial access server. Serial and synchronous/ asynchronous ports are ideally suited to transport legacy traffic across a TCP/IP network, facilitating network convergence and eliminating separate leased lines for this traffic.
