COMMON APPLICATIONS
These highly flexible interface cards enable several important applications.
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 (Figure 2).

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