About the Hotwire 7975 Standalone Termination Unit

Network Configuration

Figure 1-1 shows a network application using a 4-port Hotwire 8775 M/SDSL Termination Unit for access concentration in a central office (CO). A frame relay switch and a router are connected, through the termination unit, to partner units supporting a host or router, and frame relay encapsulated or unframed data.
