Leased-Line Backup Application Example
Another common application example for your 2185 is the Leased-Line
Backup application. In this example, the 2185 is again used to connect a
mainframe to remote users. The primary connection is through a digital
network via DSUs (Digital Service Units). The backup route is through
leased-lines via dial modems. Figure 3-10 shows this application.
