Network Configuration
Figure 1-1 shows several configurations including a network application using a
2-port Hotwire 8784 M/HDSL Termination Unit in a central office (CO). In this
configuration, 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.
This figure also shows a standalone-to-standalone configuration using either
another Hotwire 7984 M/HDSL standalone unit with a DSX-1 interface or a
Hotwire 7985 M/HDSL standalone unit with an EIA-530A interface.
