Synchronous WAN ports are used for high-speed dedicated connections between two remote local area networks (LANs). Once a connection is established between two remote sites, a wide area network (WAN) is created.
Synchronous WAN connections take place over dedicated leased lines, Frame Relay connections, switched 56Kbps lines, or ISDN lines. Connection rates can range from 9600bps to 2.048Mbps (E1). PortMaster products support any of these connection types that use one or more synchronous ports. For most applications, a dedicated line connects two PortMaster routers, which are located on separate remote networks.
